Joce linked her arm through Peter's arm, and leaned against his shoulder, grinning at their mutual transformation fun. The mirrored smile on Peter's face said he enjoyed it as well.
Still, they were now back in their "normal" bodies after messing with the creep in the bar, so it was high time to make the shoulder she leaned against a bit more...cushioning.
Keeping her changes slow and steady, Joce made sure that Peter didn't notice his shoulder puff out and bulge, eventually reaching the size of bowling balls. Spreading the change downwards, Peter's biceps flexed and relax as they rose like baking bread, surpassing his shoulders to the size of basketballs. Joce rubbed her hand against the taught flesh, silently cooing at the visions of the muscle god running through her head.
Peter's chest began to barrel out as his pecs swelled outward, his shirt stretching to show their cut shape and clinging to them like second skin. The change now encompassed his entire body, calves like cannonballs, and his thighs shown through his now stretchy jeans, which left little to the imagination. Joce had Peter unconsciously adjust his stride before going to work on his butt. She ran her hand over it, feeling it rise and expand into the perfect muscled ass, with just enough give to allow her to grab.
Girls waiting outside the clubs began to let their eyes latch onto to Peter's body. He was only a few inches taller than he'd been before, but thanks to Joce's muscle enhancements, Peter would easily push 400+ pounds on the scales.
Shooting the jealous girls a brilliant smile, Joce went to work on her piece de resistance. The bulge in the front of Peter's pants began to swell to a fantastical size, suggesting he might have stuffed a melon down his pants. However, the pants had stretched to nearly to the point of second skin, allowing the discerning viewer to note that it definitely wasn't a melon resting in front.
It was at that point that Peter's poor underwear, unchanged and under stress from both the back and the front, gave way, and the Peter became aware of his new body.
Joce attempted to look innocent, but it was hard to keep her hands off the muscles she adored...
What was going to happen next?
