Biff tried to go to bed early that night, but he couldn't sleep. He had checked his ass in the mirror when he got home, and it definitely looked bigger than before. In fact, it looked kind of girly. He tried on his Speedos, and they still fit reasonably well, but he was a bit worried about the swim meet the next day. Would the change to his rear end affect his performance?
Biff tried to distract himself by looking at some porn online. He surfed around for a while and accidentally clicked on a shemale video. For some reason, the sight of a chick with a dick really turned him on all of a sudden. Making sure his bedroom door was locked, Biff started to jerk off.
When Biff felt himself about to orgasm, he grabbed some tissues. His hips bucked as he came, just before he got the tissues to his crotch, but it didn't matter... nothing came out. Biff touched his cock, and felt the sensation at the tip starting to fade. The skin started to look slightly shiny... almost plastic-looking...
"Oh fuck!" said Biff, moments before his dick fell off again.
Sure enough, he had a smooth, pink pussy in between his legs again. He picked up the double-ended dildo that had been his cock a few seconds ago. Both ends were erect now - instead of the soft, floppy rubber it had been before, it was now stiff and firm. One end was significantly bigger than the other this time. Biff dug out a measuring tape and measured. The big end was a full 9" long, and the smaller end was only 5" long, and a bit thinner too. The lump in the middle that looked like it was a sculpted scrotum seemed sized for the small end, rather than the big one.
Biff knew that his penis had been a full seven inches long, when hard, before any of this started to happen, so he was confused about why there was such a disparity now. Shrugging, he tried sticking the dildo back into his pussy, small end first.
The small end slid inside him easily enough, but other than feeling kind of nice, it did nothing for him. He flipped the dildo around and tried jamming the big end inside. It felt really big, almost uncomfortably so, but still nothing happened. Biff tried sliding it in and out while rubbing his clit again, but STILL nothing happened. After a long while, he managed to bring himself to a small orgasm, but then the dildo fell out of his wet pussy, leaving him feeling scared and frustrated. What was going on? And how was he going to compete in his race tomorrow without a penis?
Biff slept uncomfortably that night, and tried to reattach his cock again in the morning. Nothing worked, though, and he couldn't even make himself orgasm this time. He was just making his pussy sore.
Feeling stressed and worried, Biff tried his Speedos on again. With his swollen ass, they pulled tightly around his crotch, and it was very obvious that there was something missing in the front. Biff was trying to stop himself from freaking out, and not quite succeeding. Finally, he tried balling up a pair of socks and shoving it in the front of his Speedos. It wasn't quite right, but as long as you didn't look too closely, it looked passably like a cock in his swimsuit. He hoped it wouldn't get too waterlogged...
