"Peter, how do you want to go out today?" Joce called from the downstairs workout room. It was four years into their relationship, living as fiancees just off campus of the university where they both attended as juniors. Joce had always been the early riser of the two of them, which gave her a chance to enjoy her warm up exercises of the day... and get herself thinking about how she and Peter would enjoy themselves. She toweled herself off, considering to herself that she should ask Peter to strengthen her back a little, since he'd been quite fond of her double Hs lately, since it wasn't competition season and she could get away with have some more extreme curves on display.
Speaking of curves, Peter walked out of the bathroom, head brushing the top of the door frame while doing so. With swimming season over, and the height of football not far off, Peter generally stuck to his larger sizes right now, much to Joce's delight. Thick muscles stood at stark attention, with his biceps larger than his head, and thick slabs of pectorals resting comfortably on a slight taut ball gut, to keep up appearances of his bulking sessions with his teammates.
Over the last few years, he'd gotten used to Joce's love of making him large, and found himself enjoying pushing the envelope in new ways. He'd almost always spend a little extra time in the bathroom, running his own hands over his expanse, marveling at the power contained under his skin. Some days Peter was a sleek power swimmer, all toned and well built; other days he rivaled Mr. Olympus and beyond, oozing rock hardness... and then other days, he let loose, letting himself enjoy food contests and just being huge, a powerlifter's physique with bloated guts that were both taut or soft, just enjoying being... big. That, of course, were nothing compared to the extreme sizes they both got to when it was just the two of the. All of them thanks to his and his girlfriend's body modification powers, which only worked on each other; not that either seemed to mind. He was thankful for Ty giving them this gift, along with the slight reality-warping aspect that had people simple accept whatever size Peter and Joce were.
Peter came down the stairs, pondering. "Hmm... well for today..."
