Jeff hung there helplessly. In spite of the rude boy's transformation into a girl, Jeff could still taste his male sweat. Where had his girlfriend gone?
A couple of voices drew closer.
"Hey, how do you think I'd look in this one?" the curvaceous blonde said, "I haven't worn a one piece since I filled out."
"Why don't you try it on? Nobody's around. Either the owner left it to dry or she forgot it."
"Well, I guess it couldn't hurt to try it on for a minute?" The blonde undid her bikini top, and hung it in the locker next to Jeff. Then she stepped out of her bikini bottom and lifted Jeff out of the locker.
Jeff had mixed feelings. This woman was hot, but he wanted his girlfriend.
"Oh, it feels like a second skin. It feels a bit tight, oooooooOOOOH, MY!" the blonde's voice changed in mid oooh from soprano to bass.
Jeff felt the woman's body change and felt himself changing too. His straps melted away as he shrank into a man's speedo, and his pouch swelled to accommodate the blonde's new manhood. She had been well-endowed as a woman, and was similarly well-endowed as a man though at lower height.
