When visiting a close friend's house, the group was surprised to see how beautiful and attractive his mother was, especially since she was over 30. Chaino and Saki couldn't help but drool over her fair skin, firm large breasts, and model-like figure. Chaino secretly drugged the drinks, waited for Hayashi and the two friends to fall asleep, and then made his move. Later, this pervert persuaded Saki to join in for a threesome for fun, as Saki had desired to have sex with Blen's mother since they first met. In the end, they were caught by their friend, and Saki and Chaino tied up Blen to continue having sex with Hayashi in front of their close friend.
