Swimming Lessons: Tim Asks Mike For Help

"Hey, Mike." Tim smiled at his friend. The other man cocked his head to the side at his friend's casualness. "I got to ask for a favor."

"That is?" Mike looked to Alison, who gave a meek wave to the man. His eyes glanced down at their thickening thighs and large hips with curiosity.

"You got to..." Tim could see a few people stare over at them and quickly led them away. The blonde man pulled Mike aside near the edge of the bleachers, keeping his voice low while Walter-son followed the pair. Another slow, warm pulse rippled through their glutes, pushing them just a little fuller. The swimsuit was now visibly struggling against their curves. The fabric stretched thin across the expanding cheeks, the leg openings cutting into soft, plush flesh that definitely hadn’t been there at the start of practice. "...have sex with her."

“Okay, It’s… not exactly what you think,” The blonde man started, rubbing the back of his neck. "This isn't Alison...it's...well..."

Mike raised an eyebrow, still glancing over at “Alison” with open curiosity. “Dude, it’s one of those sex clones you keep talking about, right? You, your brother, and your dad talk about that shit all the time."

Walter-son and Tim exchanged a quick glance. Walter-son's cheeks flushed pink.

“Yeah…” Alison’s voice came out in a light, slight embarrassed laugh. “You caught me. I’m a sex clone. Just… helping out today.”

Mike let out a relieved laugh, shoulders relaxing. “Thank god. I wasn’t about to cuck my best friend. That would’ve been messed up.” He looked “Alison” up and down again, eyes lingering on the way the swimsuit was riding up higher and higher on their noticeably rounder, thicker ass. “So… you’re cool with this? Because damn, you’re looking extra thicc today. Like, really thicc.”

Walter-son felt another insidious swell deep in his rear; a slow, teasing, unstoppable. The cheeks pushed outward and downward, gaining a heavy, jiggly softness that made even standing still feel different. (S)he had to fight the urge to reach back and adjust the suit again. Instead, (s)he gave Mike their brightest, flirtiest smile.

“Extra thicc and still growing, apparently,” Walter-son mewled out, trying to sound playful even as panic and a strange new sensitivity warred inside him. “The iBod that made me glitched. My ass won’t stop expanding. Coach Ramirez is already suspicious. If we don’t do something soon, this is going to be all over the team Snapchat.”

Mike’s grin widened, clearly intrigued. “So you need me to… help reset it? With sex?”

Walter-son nodded, biting their lower lip as another warm wave made their swelling backside wobble slightly. “Yeah. A good, hard fuck from behind should flood the system with enough hormones to pause the growth temporarily. I'm planning on going to the locker room, are you in?"

Mike didn’t even hesitate. “Hell yeah, I’m in. As long as it’s just a clone thing and Tim’s cool with it.”

Tim looked mortified but nodded stiffly. “Just… keep it quiet. And don’t be weird about it afterward.”

“Deal.” Mike clapped Tim on the shoulder, then turned to Walter-son with a hungry look. “Lead the way, ‘Alison.’”

The three of them slipped toward the girls’ locker room while the rest of the team was still focused on drills. Walter-son walked ahead, hyper-aware of every jiggle and sway in their backside. Their ass had grown even more during their short conversation. Their cheeks were now unmistakably thick and round, the swimsuit wedged deeply between them like a thong. Each step sent a soft, humiliating bounce through the expanding flesh, and the sensitive nerves lit up with every brush of the tightening fabric.

Once inside the locker room, the door clicked shut behind them. It was empty for the moment, the echoing space smelled of chlorine, old sweat, and shampoo. Mike wasted no time, stepping up behind Walter-son and running his hands over their dramatically swollen curves.

“Fuck… this glitch is doing wonders,” Mike murmured, squeezing the soft, heavy cheeks. “Never seen Alison’s ass like this. So big and soft already…”

Walter-son gasped as the touch sent sparks shooting through them. The expansion was still creeping forward, slow and relentless, making his rear even plumper under Mike’s palms.

“We don’t have much time,” Walter-son whispered urgently, bending forward over one of the benches and arching their back. The swimsuit was stretched to its limit, the material digging into the deep cleft of their ass. “Just… do it. Before it gets any worse.”

Mike hooked his fingers into the leg openings of the suit and yanked it aside, exposing the massively swollen, jiggling ass that no longer looked anything like the real Alison’s athletic bubble bottom. Walter-son felt the cool air on newly expanded skin, followed by the hot press of Mike’s cock against the cleft.

Tim stood guard near the door, his face burning from this predicament, while Mike pushed in slowly at first, then harder, gripping the thick hips as he started to thrust.

Walter-son moaned in a soft girlish twee— as the first deep strokes sent waves of pleasure crashing through their overly sensitive, still-growing body. Each powerful thrust made the swollen cheeks ripple and bounce heavily. Their expansion was temporarily forgotten in the rush of hormones and sensation.

But even as the fucking intensified, Walter-son could still feel it: that faint, warm tingling deep inside, stubbornly refusing to stop completely.
