This is such a cool scenario, as I imagine it…  A futanari has a swim competition but gets aroused being near all the hot hentai girls in tight swimsuits, or maybe she likes the guys in speedos either way the futa can’t swim with an erection creating more drag in the water even if her swimsuit is super tight so she quickly jerks off in the corner before her swim race blowing her cumshot on the wall.  Anyone else have a better story to go with this hentai?
