My childhood friend Saki asks me to accompany her to volleyball practice since the recital is coming up.
I was bored too so I said yes without thinking much about it, but there were traps of temptation posted all over the place.

Stretching spreads her legs wide open!
A close-up of her crotch during warm-up exercises!
Her flexible legs spread open, giving you a clear view of her pussy!

Is it unconscious? ? Or intentional? ?
Her flexible crotch stimulates me, and I get an erection that makes me cringe.
I've never thought anything of my childhood friend before, but now I'm starting to feel like a woman and I can't concentrate on practice!

(1) My childhood friend's flexible body gives me an instant erection! Out-of-control leotard sex
(2) Jealous of Saki giving the coach a blowjob, he gets a depressed erection
(3) Continuous ballet ejaculation sex that just won't stop no matter how much he ejaculates
(4) Late-night training... uncontrollable piston-like sex as they seek each other over and over again

The combination of Saki's still-developing body and her tight leotard makes it impossible to control his reason...
