I walked into the unisex changing rooms, and heard moaning, faint and coming from the shower area. I was curious, so I walked back there, box in hand to investigate. I was quiet, sneaking around, following the moaning. I found one room with the door closed, and stood there listening to a couple finish having sex. He asked what she wanted him to go on, she replied find a tissue or something. He told her he had to find a tissue in another stall real quick, and before I could move, the door opened, and he stood there eyeto eye with me. He looked at me, then the box, and grabbed a swimsuit out of the box. He stroked his penis with it, and just as I was pleading for him to stop, he came all over inside the swimsuit. He tossed it at me, and I caught it by the strap, then he smirked and closed the door.
I stood there for a second and wondered what to do, then I thought, why not wash it silly. I went into another shower stall, and closed the door, locking it. I set the box in the room locker(waterproof), hung the swimsuit up, and looked at it. It was a one piece silver metallic swimsuit, with a zipper front 3/4 the way down, and a high cut thong back with Y shoulder straps. The interior liner was black, which made the cum stand out. I noticed it was all still in there. I put my finger in it, and scooped a little out. It was extremely goey, and stringy, playing with it I felt really girly, and suddenly I had to taste it, so I licked it. It was yummy, so I licked it agian, and again, then licked my fingers clean, swallowing it all, feeling really horny, but for cock and for sperm. My male self cried out, while my my female side giggled, gaining more control every moment.
My eyes go back to the swimsuit, and I start to think about putting it on. My male side tries to protest...
