KSBJ-158 - My new stepmom is constantly teasing and seducing me

Mio Saionji gives a great performance. The story—where she actively seduces her husband's stepchild despite having a good relationship with her husband—adds a lot of depth to the experience. Penetration is limited to just twice: once with the husband and once with the stepchild. Also, they spend way too much time on foreplay, making the actual sex feel a bit too short, which is a bit disappointing.
