The Otaku in 10000 B.C.

简介

Unlucky at love and with nothing going his way, Oota's world is turned over when he's magically transported into a land that time forgot. Surrounded by nurturing, big breasted cavewomen with seductive banging bodies, Oota's going to have his hands full teaching them a bunch of firsts in the history of sex! (Source: FAKKU)
