The main character, Yuichi, is exhausted on his way home from a drinking party with two gals "Riko" and "Anna", who have a rotten relationship, and tries to rush to Yuichi's house because he can't drink enough.
In the meantime, Yuichi is forced to rub their raw breasts by the two of them discussing the tondemo theory that "Yuichi is an erotic woman who doesn't fall no matter what he does"!
As expected, Yuichi was at the limit of his patience, and the moment he arrived home, the after-party began to be with two plump erotic bodies——!?
