Chichi Ai Dorei Choukyou Keikaku

This is a titjob-only training game.
Cowgirl-style titjobs, vertical titjobs, upside-down titjobs, suspended-in-the-air titjobs, while-she-sleeps titjobs, hand-holding titjobs, exhibitionist titjobs... she'll do it all!
There's every kind of boob play you can imagine.
Every last drop of semen gets shot between her boobs. That's the one unbreakable rule here.
You can also train the girls in special situations like semen baths or virtual reality scenarios.
