A man living as the masturbation pet of multiple female students. This work is a compilation of the incredibly erotic daily life of such an irresistibly delicious man. The number of partners at once varies. Sometimes it's one person, other times it's multiple at the same time! Regardless, there's only one dick! But there are countless holes to insert into! And the women's sex drive is insatiable! This situation is like both heaven and hell. No softening allowed! Repeatedly achieving erection after erection, using mouth and hands to serve with all his might! It's exhausting to the point of death, but it's an enviroment every man should experience once. That's the greatest appeal of this work!
