A dominatrix girl and a tiny cock

We were at a hotel and they were having a fetish convention. I met this really cool Domme. I found out we had something in common we liked to make fun of small pathetic penises. She came over in a vinyl dress with a surprise underneath it. She teases Jack's small penis getting him hard and not allowing him to cum. She strokes it, slaps it while making fun of it all of the time. Then its surprise time, she pulls out her strap out from underneath her dress and compares it to Jacks small penis. Guess who wins?
