It wasn't his body.
That's what Tommy told himself and he lost the bet with his buddy Ron. Tommy really should've quit sports gambling - he never won - but this bet cost him a lot more than money.
Tommy had to take one of those pink pills and turn himself into a woman, then go as Ron's date to Ron's company holiday party. After he transformed into a woman and felt really weird, Tommy told himself all those weird feelings weren't really him, they were his body. Like how his body got all flushed and warm when he stood next to Ron...
The holiday party was weird too. There had been so many eyes on "Tammi". "She" felt so small and vulnerable, but also desired and pretty. "She" had a few drinks and hung on Ron's arm the whole night. He was sweet and attentive, and even called out some of his more lecherous colleagues' stares to get them to quit it. "Tammi" liked that Ron was so protective. It made "her" want to cling to him even closer.
By the end of the night Tommy recognized his body was feeling more than 'close' to Ron. Tommy's woman's body was turned on and horny and grateful. It felt wonderful to be tipsy and wet, and one thing led to another as Tommy realized he couldn't deny his body what it wanted.
Only when Tommy was staring down in disbelief as he came hard on Ron's dick did Tommy realize there might be more to this than just what his "body" wanted. Tommy had really had a good time that night, playing Ron's girlfriend, and the most incredible orgasm of his life made him realize that maybe - just maybe - he'd be happier as Ron's girlfriend for real.
In the end it wouldn't be something Tommy would have to agonize over too much. Having lost the bet, Tommy was responsible for purchasing the pink pill himself. Figuring he was going to have to buy clothes and who knew what else as a woman, he'd opted to minimize his losses and buy the cheapest pink pill in the store. There was a sale on pills branded as "Resistance". Tommy thought it was just a marketing name and that all the pills were treally more or less the same. If he'd read the box more carefully, he might've learned that an "Resistance" pill became permanent if you orgasmed while you were on one.
When Tammi did figured out her mistake, she was pretty embarassed. It didn't take long for her to ask Ron if he wanted to date her for real though.
Ron of course said yes. How could he not? All other benefits of dating your best-friend-turned-lascivious-woman aside, there was just something super hot about the way she'd loved to watch her "body" get fucked.
They were going to make a great couple.
