"Mark, I love you honey, but you did accept the bet, so, i'm going to turn you into a pair of black silk panties." You say.
Mark half smiles, half frowns at this, even as he begins to shrink his flesh takes on a fluid-like sheen and begins to wave and slither as if it had a mind of it's own as Mark shrank int his clothes, eventually getting swallowed up. Squealing, You rush over and dig through his clothes, finally finding the black silk panties.
"Well girls, we should go get cleaned up. I don't want to gross my boyfriend out by putting him on all sweaty." You all make your way to the showers in the woman's locker room. Grabbing your bag from the locker, you remove some soap, shampoo and a towel, grabbing your change of pants and your blouse, leaving the thong you had brought. Then finding the bra, you checked your watch. By the time you got out of the shower, your breasts should grow back. Grabbing the bra and Mark, being careful with him, you made your way to an empty shower stall.
Suddenly realizing that you were about to get naked in front of him for the first time, you tried your best to give him a good view of your body. Then you started stripping, teasing him first by pulling off your shirt, over you flat chest. You threw the shirt on the bench close by and merely shrugged out of the useless sports bra, tossing it with the shirt. Now came the shoes, then the socks, ever so slowly. You knew you were taunting him, but finally got to you shorts. Leaning up to him, you ask, "You want to know something?" not expecting an answer, you continue."I run without underwear." then you tease a little more by slowly peeling the lip of your shorts down your waist, making a little dance out of it, one of swaying hips and curves.
You were sure he was screaming now, and pulled them down faster, finally dropping them on the bench too. Then you stood and turned toward the shower controls as you turned it on, working it up to the desired temperature. Then you proceeded to preform an exotic belly dance as the warm water fell over you. As you swayed, you would turn to get more water to fall over your body. As you soaped up, you tried to make it look as sexy as possible. "Unfortunately, you'll have to wait for more." you tell Mark as you lather up your hair to wash it. In truth, you could think of no way to make that look sexy. when you were done, you turned off the water and began drying off. However, you noticed your breasts beginning to grow and moved the towel out of the way so Mark could watch.
Finally, they were as big as the were going to get, so you finished drying off. You reached for Mark first, feeling his soft fabric in your hands. It felt so good as you pulled him up your legs to rest between your sex. His caress was soft and smooth, gentle. It made you horny. You let him watch as you proceeded to don the bra, then your shirt. "Oh, my god, you are so sexy when you want to be." you heard a man's voice, and almost freaked out, until you realized it was coming from Mark.
"God! you scared me!" you say. "Well, it was my first time trying to be sexy. You feel so good, you make me horny." you whispered. "Sadly for you, I need pants before I can leave."
"Oh, well." Mark replied as you pulled your pants over him.
