Tickle Tale

"I bet that I can tickle you and make you do anything I want you to do.""And if you can't tickle me?" I asked."Then I'll do anything you want me to.""Anything?"Bella nodded. "If I tickle you, you'll do anything I say, and if I can't tickle you, I'll do whatever you want."I noted that she was now leaving off that the bet had the additional step of her being able to make me "do anything". But since I wasn't ticklish in the least, I didn't make an issue of it.
Instead, I said, "If tickled, I'll do, if not tickled, you'll do anything."She nodded. I started thinking about all the things I could get Bella to do. "So, how does this work?""You wear a skimpy string bikini and hold the upper strings between your teeth. If I tickle you enough that you open your mouth, I win.""You just want to see my boobs." Not that my breasts were anything to salivate over, but still.
She shrugged. "That's just a bonus.""Done, " I said. We shook on it.
