Shota Iijima picked up erotic books during his childhood and suffers from a severe foreign sister fetish.
Thereafter, from the years between his age of 12 to 15, he masturbated 999 times. For his 1000th round of masturbation, he had been transferred to a different world.
And Shota is sold as a slave.
A paradise for women and hell for men… Valhalla, the penis mansion.
