How do you play this game?

Doesn't seem like you can do much except mess with her clothes and use the buttons on the lower left.

you can put a blindfold on her..

Hahaha, you can ejaculate on her and then remove her clothes, leaving the cum untouched. That's a total magic trick.

Also, when you click that button again, the screen flashes similarly to the first time you click it. I think that's implying some kind of reverse orgasm where the unseen male protagonist of this flash animation sucks it back in.

This is great.
