Fertilization Training (種付調教)

Despite becoming the first volunteer soldier ever, our protagonist who has never held a proper job in his life starts off by protecting the secret of the one and only pilot who can protect the battleship.
You must fight in order to maintain the motivation of that pilot, by using your own young body which has exploded in a great shock of sex appeal.
Masturbation, titty-f*cking, penetration of foreign substances aside, release your lust by ejaculating into mouth, vagina and anus to your heart’s content in this training simulation game!
