Andy should’ve messaged that weird patron again because he didn’t remember the full effects of the toy. Their message history was deleted somehow. He went back to the website to try and find the original listing, and while he saw other magical stuff, he couldn’t find the same item that he had received, even in his order history. As soon as Spencer left with it, he started to wonder if there was a chance that it did more than just grow dick size, and he couldn’t remember if there were special instructions. Regardless, the magic was still working, as evidenced by Spencer’s reply text.

Andy was a little worried about letting an already-attractive straight boy get away with fixing his seemingly-only flaw. Maybe that tiny dick had humbled him. He figured the size would go right to his head and make him a cocky fuckboy like every bully from his past. But at the same time, Spencer had been so nice to Andy that afternoon; it was hard to imagine that his personality would flip so dramatically. Andy was also hoping that if Spencer did want to experiment, he wouldn’t insist on topping for some toxic masculinity bullshit reason. Not that Andy never bottomed; it was just rare. Same for sucking dick — while he sometimes fell in love with a pretty cock, he was usually much more interested in a man’s ass, his hole, and opening him up nice and slow.

So, sure, Andy was a little disappointed by the nature of Spencer’s text, but he couldn’t blame the guy. He must’ve developed a size complex at some point, so maybe this was good for him. And Andy also couldn’t help but wonder just how much Spencer had managed to grow. Fuck, actually the thought was pretty hot. The dude was sex on legs, 24/7, so who could blame Andy for wanting to contribute further improvements?

Andy drove a little recklessly to the address. While he was hoping that Spencer had had a change of heart after using the toy, he wasn’t at all prepared for the extent, and exactly what was waiting behind Spencer’s apartment door. The doorbell was answered almost immediately.

“Fucking, hell, Spence!” Andy whisper-yelled, pushing the jock back into his apartment and shutting the door. Spencer was completely naked, except for the backwards baseball cap he was still wearing. “Do you want your neighbors to… ohmigod, like, what the hell happened to you?”

“Um, hello to you too, bro?” Spencer looked a little offended.

“Okay, sorry, that was so rude of me.” Andy rolled his eyes. “Hi, hello Spencer. Lovely to see you for this 1 AM booty call. Question, why is what I am seeing of you right now so different from what I saw so recently?”

Spencer just looked confused at his phrasing.

Andy bit his lip. Why was slightly stupid turning him on right now? “I’m sorry, let’s start over. Hello. Good to see you again, tonight, since we saw each other a few hours ago. You’re looking extremely hot, but different from before. I am surprised to see your dick out so soon.”

This time Spencer blushed pleasantly. “Heh, thanks bro. Uhh, sorry for being naked? But my underwear didn’t feel right, so I gave up on clothes.”

Andy sat on Spencer’s couch, waiting for him to connect the dots on why that was. The bigger man silently joined him, leaving absolutely no space between them. Andy wanted to run his hands through the light blond hairs on his muscled chest, but he figured that would cross the “bro” line.

“How big is your dick now?” Andy asked amicably, noticing that he currently looked average in size, instead of small. He hid any disappointment; Andy had thought the toy would give Spencer a cock just as big as his own, but it was still smaller than his original 6.5-incher.

“Almost six inches. I’ve cleaned your toy if you want it back.”

Andy hadn’t really intended on getting it back for himself. He watched Spencer’s expression. There was clearly something else on his mind. “And did you notice that your dick isn’t the only thing that changed?”

Spencer looked… embarrassed? “I didn’t think you’d be able to tell…”

That made absolutely no sense. “Um… bud, do you, like, own a mirror?”

Spencer’s embarrassment broke for confusion. “Wait, a mirror? What are you talking about?”

Andy couldn’t hold back any more. “Fuck, Spence, your ass just looks… fantastic now. Like, just hours ago you had a tight little jock booty. Cute, but nothing special. This… Spencer, that’s a bubble butt and a half that any gay man would kill to have. And I think your hips are wider, your thighs look thicker, and if I’m not mistaken, your pecs look way beefier and not so tight and flat.”

Spencer rushed to the bathroom to look at himself in his only mirror, and Andy followed in awe, considering their (clearly opposite) experiences with the prostate toy. It hadn’t changed anything about Andy other than his dick, and that got enormous! But for Spencer, it only gave him a relatively average 6-incher but made him look like a gym-dedicated bottom!

Andy couldn’t stand how sexy Spencer looked, especially twisting his waist and trying to see his bigger ass from all different angles. What he needed was a full-body mirror like Andy had back home. But regardless, his mind drifted back to thinking about the toy, Spencer’s changes, and how they differed from his own. Spencer must have done something differently to get different results, and he wanted to know what that was. He had no need for the toy himself and was growing curious what might happen if Spencer took another spin.

“So, yeah, it looks like you got more than just a bigger dick out of the magic,” Andy commented dryly.

Spencer still looked a little embarrassed, even though he was clearly pleased with himself too. He led them from the bathroom back to his bedroom where the freshly-cleaned toy was ready on his nightstand.

“What’s up?” Andy asked point-blank, sitting on the mattress.

“Uhhh… I know why it happened, is all.”

Andy was surprised. Not to be mean, but Spencer wasn’t one to draw many conclusions. Unless it was about baseball. “Oh really? Why’s that?”

Spencer adjusted his backwards cap and rubbed the back of his neck. “Well, the whole time I was, you know, using the toy, I was wondering what it’d be like if it was your cock fucking me instead.”

Andy couldn’t help it when his eyes went wide in shock, and Spencer continued quickly, “And bro, I know how that sounds because I just told you I was straight, but like, I dunno, I guess I’ve never thought about it before and maybe I am a little bi? Or extremely bi? Or just very, very, very into hitting that spot the toy is able to hit. And bro, if you can do that, with your big beautiful cock…” Spencer looked like he was about to beg.

“Wow, oh, this is…” Andy was at a loss for words. “Spencer, you’re… gorgeous, and sweet, and… well, do you still want to do that stuff with me?”

Spencer looked hopeful. “You mean you’re into that too? I didn’t wanna presume just because you’re gay and have a huge dick that you’d wanna fuck me…”

Now that was a lie. He totally knew Andy would be into this, but he was being too vulnerable and sweet to tease him about that. If Spencer wanted to act all submissive, Andy would gladly take the reins.

“Well here’s what I’d be into,” Andy said assertively in his light voice, pulling Spencer by the hand into bed with him. “Either you can put that toy back in your ass and suck me off while we watch what a round two does to your body…” Spencer’s pupils dilated, and Andy continued, “Or I can fuck you for real so you can get a comparison against the magic toy.”

“¿Por qué no los dos?” Spencer asked eagerly in a bad Spanish accent.

“Oh, so you’re a greedy bitch. This is gonna be so fun.” Andy swore he saw a drip of pre develop on Spencer’s half-thickened dick when he called him a bitch.

“Okay, get ready for a late night and get that toy back inside.” He bit his lip watching the naked jock lean over him to grab it off the nightstand. “I’ll bet it feels even nicer this time around, judging from the looks of that juicy hole.” He slapped a cheek possessively, watching it wobble.

If Spencer’s deep, gravelly moans were any indication, Andy was right on the money. He eagerly lubed and inserted the toy.

“So imagine I’m not here, Spence, what did you do earlier to get yourself off? Jerk to some porn?”

Spencer caught his breath, laying down in the middle of the bed. He felt shaky from the magically electric zaps being a little too pleasurable. “No, I— I already told you. I was laying here, thinking about you, and learning about my g-spot.”

Andy watched in awe as Spencer flexed a practiced pattern, his dick twitching with pleasure but remaining ignored. “You didn’t touch yourself at all?” he asked calmly so it didn’t sound like that was surprising.

“Nah, not my dick. I wanted it to last because it felt soooo gooood.” He took a breath. “I always jerk off too— too quick and never really enjoy it.” Breath. “Hell, I don’t think I’ve enjoyed sex as much as I love how this toy feels!”

Andy was shocked, and maybe a little guilty. All the same, he was going to reap exactly what he had sown. How could he have known? Apparently different uses caused different effects. He must’ve naturally had the urge to jerk off to keep his focus on his cock, and sure it had been a quick session but it was how long he came afterwards that he remembered most.

Clearly, though, Spencer was enjoying himself. Andy didn’t have to force a thing, and Spencer was the opposite of upset. The moment Andy lowered his shorts while sitting on the edge of the bed, Spencer was back up out of bed, on his knees, between Andy’s legs, worshipping the nine-inch masterpiece. The muscle bro was quivering the whole time, still having fun with the toy, but careful not to push himself over the edge. Andy groaned and moaned in a higher and higher pitch as Spencer made love to the entire length, giving him a brief hand job before leaning in and kissing it, then running his tongue along the length. Andy didn’t say a word as Spencer had his own fun, obsessing over every musky inch. Maybe he was wishing his was the same size or bigger, or maybe just enjoying another man for the first time.

Spencer’s cloud of embarrassment from earlier was gone, and Andy pushed him off his new obsession so he could lean in for a rough kiss. Spencer’s thick stubble scraped against Andy’s smooth face as their tongues met. Andy finished undressing then centered himself on the bed, with Spencer rejoining him but staying between his legs — he didn’t want to let that beautiful cock get too far away. Then Spencer began taking it into his mouth with purpose, attempting to deep-throat the entire length at once, choking, then working himself up to it again. Andy watched in awe at the beautiful sight below him, Spencer making love to his cock and letting out all sorts of vulgar slurping sounds.

“Fuck yeah, you really do love cock, don’t you?” Andy asked rhetorically.

Spencer looked up at Andy, making eye contact and moaning with his mouth full as he realized what he was doing. He didn’t stop, either.

He fell into a sort of rhythm of trying to take more and more length, pulling back and dipping down again, in time with his asshole flexing around the toy. Andy’s hands began roaming Spencer, practically in heaven — first, that he was getting the opportunity to play with this sexy jock bro, but second that Spencer was becoming a cockslut before his eyes. Most of his experience topping came from other twinks, so it was a novelty to have someone so large and hairy taking up the space between his legs, begging for cock. Eventually, even Andy couldn’t resist how good Spencer was getting, and he tapped the back of his head.

“Spence, I’m gonna come if you don’t—” Andy gasped, but once he said that Spencer only redoubled his efforts, and soon Andy yelled in ecstasy as he unloaded in Spencer’s mouth. The new dick-devotee swallowed because his reflexes didn’t know what else to do, and the realization of what he was doing coupled with the toy pushed him over the edge moments later, unloading into the sheets while his dick was once again untouched, flaccid.

While Andy’s load had been moderately large, Spencer’s toy-assisted orgasm was overwhelming. But this time, Andy got to spectate the changes. Spencer’s dick did swell up bigger, inflating to a rather flaccid eight-and-a-quarter inches. Just edging out Jeff for length, and maybe even girth, but Andy was quick to note that it wouldn’t compete in firmness. Even as turned on as Spencer clearly was, he wasn’t erect at all. His balls got bigger too, but that wasn’t Andy’s focus at all. As he grabbed the bouncing bubble butt in front of him (and Spencer groaned in approval) it swelled up even larger, going from a normal big booty, to two fat melons strapped to Spencer’s back.

“Oh wow, I can’t wait to fuck this,” Andy said, slapping one cheek and watching the skin ripple, and Spencer grunt and squeal in pleasure.

“Oh fuck,” Spencer panted, looking up but still out of breath. “I need you to fuck me.”

“Oh Spence, those are some DSLs you didn’t have before.”

“Uhhh, what?” Spencer asked, confused.

Andy swooned. “I watched your ass get fatter, but I just noticed, you also got some nice dick-sucking lips now.”

Spencer reached a hand up and kissed his palm, and sure enough, it was nothing like the thin, dry lips he’d always had. These were plump, wet, and pouty.

Andy got a little jealous of the self love and leaned in for a kiss of his own, moaning as he bit on the swollen lips. “You’re one hot fucker, Spence. But I should take this out before you get going again.” He reached around to pull out the magical prostate toy, noticing that while it was once jet black it was now a uniformly grayish color.

“Do you wanna stay here tonight?” Spencer asked simply, pulling his thoughts from the magic immediately.

“Yeah, it’s already getting late,” Andy answered with a yawn, stretching backwards in the bed.

“Don’t get tired on me, you still owe me a real fuck.” Spencer pouted.

Andy laughed. “Believe me, I’m too eager to wait till morning to get a piece of this,” he said, grabbing one cheek and jiggling it.

Spencer sighed, seemingly in relief.

“What’s on your mind?”

Spencer settled his stubbly face on Andy’s smooth chest and smiled. “Glad that still feels good after the toy came out. I was wondering if it was showing me new pleasures, or just fooling my brain.”

“So after I took it out you didn’t, like, become a homophobe or anything?” Andy asked, half-joking.

Spencer just laughed. “No way I could be afraid of feeling like that again. Even sucking you off was awesome.”

Andy smiled.

“But I do have a question for you…”

“Shoot,” Andy said.

“Do you think you wanna be… even bigger?”

Andy’s eyes went wide, which Spencer couldn’t see.

“Like, don’t get me wrong, I love your size so if you’re happy I’m happy. But if you fuck me with the toy in yourself… I bet you’ll get even bigger!”

“Oh, fuck, Spence, that’s hot but… don’t you think I’m already a little too big?”

Spencer turned his head up to look at Andy. “No way, bro. I can train my throat more if my blowjob wasn’t good enough, that was just a former straight dude’s first attempt.”

Andy laughed deeply, shaking his head. “But like, I have no clue what’ll happen. My ass didn’t get bigger when I used it. But yours did. And neither of us could control how much we grew.”

“So?” was all Spencer said.

Andy considered that.

So?

Did he want an even bigger dick? Well… hypothetically, sure. He knew nine inches was far from the limits of human physiology, but he also knew that was getting into a different territory, where people would be more fearful of — and less excited by — his size. As long as Spencer was still on board, that meant theoretically other potential partners existed. Maybe he could indulge himself. And if that meant letting go of some control… so?

Andy acquiesced, and Spencer was eager as he prepped the toy and Andy’s hole with lube. The toy slid in easily once more, and once it was inside Andy felt a rejuvenating surge of vitality. While turned on, he was a little afraid of being able to muster up another load, but the toy made that a non-issue.

Spencer didn’t waste much time on Andy’s butt, instead rolling him onto his back once the toy was in place and stroking his cock to hardness once more, coating it in a healthy amount of lube.

“Dude, I’d never thought I’d call a dick pretty before,” Spencer admitted to Andy, “but yours really is. I can’t wait until this thing is in me, bro.”

Andy was starting to believe his circumstances, if only because the pleasure was too amazing to be imagined. “And your ass is gorgeous. Can’t wait to teach you what a toy can’t do.”

Spencer shivered. “Oh, fuck, my hole is literally quivering for you, bro.”

“Yeah? My swole muscle bro is just a big fat pussy when it comes to my cock, huh?” Andy forgot how much he loved dirty talk. He flexed around the toy in his ass.

“Oh shiiiiiit,” Spencer moaned in his deep voice. “I am, I am a pussy for cock. Please Andy, put your cock in my pussy!” Spencer rolled over in bed onto all fours and arched his back, sticking his fat ass up in front of Andy. He quickly got behind him in bed and teased his fingers along the inside of his asscheeks.

“Ooooh,” came the wordless groan from below, but Andy ignored him.

“That toy was pretty small, so it didn’t really stretch you open like I’m going to.” Andy suddenly plunged two fingers inside, meeting no resistance from the silky-smooth, lubed skin.

“Pleeeeease,” Spencer begged without elaboration.

“I guess this magic ass was made to be fucked because you’re already relaxed.” As evidence, he gently pushed a third finger inside with no trouble.

“Harder!” Spencer demanded.

“No, not yet, I’m trying to get you ready for girth first. But maybe I don’t need to.” Andy pulled his fingers out, then lubed the rest of his hand. He pushed four slick fingers inside together, eliciting a whine from Spencer. Andy had a devilish thought and tucked his thumb inside too, then kept pushing until he passed the widest part of his hand and Spencer’s ass sucked him inside to the wrist.

“Whoooaaaaaaaaaa,” Spencer’s eyes rolled in the back of his head from the new type of pressure as Andy curled his fingers inside.

“Ok, clearly you’re up for whatever,” Andy said with a laugh, pulling out his fist and flexing the toy in his own butt once more. His cock throbbed in desire. “Most of all, I wanna make sweet love to your bro pussy.”

“Yeah, yeah bro, fuck me, fuck my fucking ass pussy, bro!” Spencer begged.

Andy could hardly wait, and pulled the fat cheeks to either side so he could more easily plunge his length inside.

“AAAIIYYYEE!” Spencer screeched, and Andy froze as he leaned on Spencer’s wide back for support.

“Shit, shit, sorry, too fast?” Andy had gotten his head and maybe another two inches of length inside, so there was still at least half to go.

Spencer gasped for breath. “No it’s, it’s just soooo much bigger than that toy,” he said in a daze. “You’re already rubbing against the spot.”

Andy went from fear to deviousness, slowing down and grinding with more pressure at what he hoped was the right angle.

“Guhhhhhh,” Spencer drooled, unable to control his vocalizations, as pre dribbled out of his engorged, useless cock.

Andy noticed the mess and reached around to grab it and give the length a few strokes since Spencer was still ignoring it. “What’s going on here, Pussybro? I gave you more dick, now why aren’t you using it?”

Andy pushed the final length inside, finally coming to a rest against his spread-wide cheeks, their balls swinging and tapping against each other.

“Pussy’s better!” Spencer shouted, spurting a glob of pre into Andy’s hand. “Fuuuuuck, you’re soooo big!”

“Milk a load out of me and I might get bigger, babe,” Andy whispered behind his ear, and Spencer shuddered in anticipation, squeezing tight around Andy’s cock.

Then Andy pulled back, and thrust forward again, not too hard, but insistently.

“Ffwhoa,” Spencer grunted.

Andy released Spencer to get a better grip on his widened hips, slapping a cheek in appreciation, then repeated the thrusting motion back to back.

“Gooooooo,” Spencer moaned, falling face-first into a pillow. “Keep gooooing.”

Andy laughed, then built up a more steady rhythm, fucking Spencer but not completely wrecking him like a more forceful part of himself wanted to. No, he wanted this to be as good for Spencer as possible, not just himself, so this wasn’t the time for a jackhammer. Clearly Spencer was having fun already, but Andy pulled out to roll him over on his back and change the angle.

Spencer’s pouty face was cute (and exaggerated by his new lips poking out of the dense stubble), but eased immediately when Andy quickly resumed his purposeful fucking — grinding and milking Spencer’s prostate for all it was worth while still feeling little zaps from the toy in his own ass. He would’ve been over the edge already if he hadn’t come so recently.

Andy pressed his lithe, smooth chest against the golden hairs coating Spencer’s pecs and abs, grabbing purchase around his huge shoulders and thrusting more deeply with his hips, grinding around to really put the pressure on. They breathed each other’s air and watched each other with a smile, breaking every once in a while to kiss or flip over and change positions again.

Andy held out from succumbing to the pleasure of the toy, until at long last Spencer moaned that he couldn’t hold back any more and shook in rapturous pleasure on a well-timed thrust from Andy. Seeing the ecstasy painted on Spencer’s face, knowing he was responsible for his first time, and feeling the tremors run through his hole, Andy finally let loose and began blasting what felt like a never-ending load into Spencer. The two men writhed together, gasping for air and each other, for what seemed like an eternity but amounted to a little over a minute.

The second session had lasted quite some time, and they were exhausted both from the activity and the extremely late hour. Andy finally withdrew himself, but became dissatisfied with how much cum was leaking out of Spencer’s well-used hole. Without thinking, he pulled the p-toy out of his ass and stuck it in Spencer to plug him up. Spencer was too exhausted to protest, or was secretly happy with the development, or both. Regardless, they fell in bed together and Andy fell asleep in Spencer’s arms not long after.

---

Andy was a little disoriented waking up in an unfamiliar bed, but the large man spooning him brought back the events of the previous night in a hurry. After basking in the memory of such an amazing night, he recalled that he let Spencer convince him to use the toy again!

Andy looked down (his chest fluttering at the hairy, well-muscled arm slung over his side) to be greeted by his morning wood. Redwood, that is. The log sticking out of his crotch was gigantic! Was this what he pulled out of Spencer last night?! Once he had the opportunity to measure he would learn that his new erect length was 10.5 inches (26.7 cm), but at first glance he thought he had a footlong! The girth was shocking, too; he jostled Spencer awake in reaching for his dick, finding that he had trouble getting one hand around the whole thing. He gave it a few loose strokes, feeling his swollen balls jostling around as well, as Spencer stirred behind him.

His arm flexed and his hand stroked across Andy’s chest. “Mmm, mornin’,” he mumbled into the back of Andy’s neck.

“Good morning, cutie,” Andy replied, turning his head to peck a kiss on Spencer’s nose.

That gave Spencer a better look at the situation he had going on downstairs.

“Whoaaaa, bro, you did get bigger again!” He was immediately more awake, and reached down to give the throbbing cock some lazy strokes of his own. Even Spencer’s bigger hands had trouble managing the new size.

“Nnngh, oh Spence, it’s sensitive!”

“Good,” Spencer whispered in his ear, turning Andy around so they were facing each other in bed. “Oh fuck, that’s hot.”

Andy looked between them to see Spencer comparing his dick against Andy’s own. While Andy was rock hard and beginning to drool pre, Spencer’s eight-incher was barely able to get a chubby.

“Is that as hard as it gets now?” Andy asked bluntly.

Spencer flushed. “Yeah, I… I think so. Why is that turning me on?”

“What? Why is it hot that you turned yourself into such a bottom that even with the massive cock you’ve always wanted, it’s just gonna be a useless flopping softie while you get your new pussy plowed?”

Spencer groaned, and started stroking Andy in earnest, with both hands, leaving his own dick ignored. “Fuuuuck, Andy, you’re so right.” He grabbed the towering cock with both hands and jerked it against his torso, rubbing it against his hairy abs and poking the head against the bottom of his beefy pecs.

“Yeah, such a good boy, such a good bottom bro,” Andy praised as his cock got massaged by the large and slightly calloused hands. “Fucking natural cock worshipper.”

Spencer lapped up the praise. Andy guided him onto his back so he could straddle his torso, thwacking his dick right between Spencer’s newly improved pecs so he could continue his worship. While he did, Andy began toying with Spencer’s nipples.

“Oh, fuck,” Spencer whispered between labored breaths.

“Mhm, I knew you’d like that. You notice how your pecs got bigger along with your ass?”

“Yeahhh,” he answered in a daze.

“You used to have tight muscle just barely jutting off your chest, but now…” Andy massaged around the nipple to emphasize how much more meat there was. “Now you’ve got muscle tits.”

“Whaaa?”

“Muscle tits, Spencer. Sure, you’ve had pecs, just like you’ve always had glutes. Well, now you got a bubble butt — Andy Jr. got well acquainted last night. Same with these tits… look at these huuuge nips!” He continued toying with Spencer’s chest. “I can grab one in each hand, and—” Andy shook his hands up and down, jiggling them and stretching out the nipple.

“AAAYYIYE!” Spencer let out a squeal of pleasure and spurted a bit of pre onto Andy’s legs.

“See how my cock is falling into your cleavage? You’ve got tits, Spence.”

“Brooooooo, you can’t be serioussssss,” Spencer groaned, unable to stop his mounting pleasure.

“Of course I am, but that’s perfect,” Andy continued, “because that means I can tit-fuck you!”

“ANDYYY!” Spencer yelled as the smaller man began pushing back and forth against his chest, refusing to let go of his nipples.

“Oh yeah, Spence, you look beautiful, baby.” Andy finally let go, then pushed down on his dick, adding to the friction as he thrusted again. He was getting close.

“Fuuuuck yeah, bro, fuck my tiiiiits,” Spencer moaned as his head fell back.

Andy couldn’t hold back any longer, and he slid forward as he pushed himself over the edge, coming across Spencer’s face and into his mouth. Immediately after tasting some, Spencer dove in for more, stretching his mouth around the new girth for the first time. (To Andy’s relief, he seemed capable of doing so without teeth. Masterful, really.) Andy twisted back, using an arm for leverage, and with his other teased Spencer’s nipple once more as the himbro polished his knob.

“Nnngguuuh!” Spencer grunted, letting loose a steady stream of cum and crunching up in ecstasy.

“Oh fuck, I didn’t realize you were that close just from sucking me off,” Andy said with a smirk, disengaging himself before realizing that Spencer was still coming. “Wait, Spence, do you have the toy in?”

“Uh huhhhh!” he affirmed in a guttural voice.

“Shit, do you really wanna be bigger? Not just your junk, but all over?” Andy hoped he hadn’t pushed him too far.

“Ohh, yesssss!” he yelled.

If Andy’s eyes weren’t deceiving him, he was picking up in momentum, rather than tapering off. And the growth was visible and obvious. As Spencer’s cock unloaded, it lengthened and thickened, swelling with pulse after pulse. But just as before, that wasn’t all that grew. Since Andy was still facing his front, he wasn’t able to see how much bigger his ass got, but his pecs swelled up even more, the areolas widening and nipples thickening dramatically. As the muscle and fat packed on, the previously moderate cleavage became borderline ridiculous. Andy’s eyes widened, and he gave a double take as he realized that Spencer was still coming!

“Shit, Spence, you okay?” Andy was worried that something had gone wrong. His cock was still getting bigger!

“Fuckin’ — amazing!” he gasped.

Andy didn’t want to pull out the toy because he had no clue what that could do to the magic, so he decided to wait it out. He manhandled Spencer around so he could get a look at his swelling ass (pushing the still-squirting dick down between his legs since the mess was already everywhere). Andy really couldn’t wait to fuck his way into this big bottom. In the mean time, he enjoyed jiggling the cheeks in his hands and making Spencer shiver. As he was fooling around, he noticed that the prostate toy, which was once jet black and just the night prior had been grayish, was now approaching an alabaster white. Just as he made that realization, Spencer’s torrent finally abated, and he began to take deep, calming breaths. Andy gave him a while to recover before withdrawing the toy gently and tossing it aside. He figured that the pigment represented the magic remaining inside, and it was probably just a regular old butt toy now.

“Sorry, Spence, I didn’t know you still had the toy in. I wouldn’t have pushed you—”

“Fucking, shit Andy, that was the best one yet!” Spencer said, excited now that he’d caught his breath.

“Yeah but bud, that was like almost five minutes! Just… go check the mirror.”

Spencer must have felt the shift of weight once he got out of bed. “Oh, shit.”

Then Andy heard him from the bathroom mirror, but not the horror he feared. “Oh, shiiiiiiit,” came Spencer’s pleased voice, and then a few minutes later, “Brooooo! Andy, c’mere!”

Andy made his way into the bathroom to find Spencer with a cloth tape measure, grinning like an idiot. “You go first.”

Andy was about eight and a half inches long while soft, and looking at the new Spencer was enough to get him hard again, to measure at 10.5 inches. Hard he was almost eight inches around!

“Okay, your turn,” he said, handing it back to Spencer.

Clearly he’d already measured himself, but he pulled his cock up and draped it across his counter to lay the tape on it again.

“Fuck me,” Andy whispered.

“No can do, bro. No way for it to get hard anymore.” He didn’t sound too bothered. “But look! A little bit over…”

“Wow.” Andy stared at the tape and finished his sentence, “A little over 13 inches. That’s crazy, dude. Well over a fucking foot long.”

“Yep!” He was so proud. It didn’t matter that it was useless for penetrative sex — he just wanted a trophy, it seemed.

“And what about the rest?” Andy was worried that he didn’t like the other changes and was fixated on his dick.

“What, my bubble butt? These tits? Shit, even my lips?” Spencer was grinning. “Bro, I’m fucking hot now. As long as I’m getting fucked, I’m gonna be happy.”

A pedant would argue that he was sexy before, too, but Andy pulled him into a deep kiss, standing on his tip-toes to reach up and over the pec shelf to get to his lips.

“More of that, please,” Spencer said in a dopey voice when they broke apart.

“Cheeseball.” Andy playfully slapped his chest. “C’mon, let’s get showered. We’re both disgusting with cum.”
