Tomoya, who has reached puberty, was worried about her mother, Yuka. Yuka unknowingly incites Tomoya with her unprotected chest chiller and panchira. In addition, masturbation, which is a daily routine every night, hits Tomoya's crotch directly.

Tomoya finally reaches the limit of patience, attacks Yuka, and pushes up violently crazy. Yuka who raises a sweet voice and cums. However, I did a pursuit piston without worrying about the sensitive pussy immediately after I got it.
