ROE-141 "I can't think of anything but you..." The stepmother, Yumi Anno, indulges in unprotected sex with her stepson while on a trip.

Yumi has been married to a man with a stepchild for three months. Although she is on good terms with her husband, her relationship with her son, Kazuki, is not going well. She goes on a hot spring trip at her husband's suggestion, and the distance between the two approaches as a result. However, Kazuki, who felt that Yumi was a woman, couldn't control her desires, and fell asleep. Yumi faints in agony after being squid many times by his intense and earnest piston. To her husband's excellent copulation that can never be tasted, her body can no longer resist his cock.
