Ma-kun, who lost his mother when he was young, grew up with the love of Yuria, who was his father's remarriage partner. After learning how to masturbate, he is a virgin who is watching slutty videos on the net every night. After that, my parents divorced, and now I live with Yuria. Recently, when I was looking at the face of an erotic actress I found..."Huh? This person looks just like my mom...! Ugh!!!!!" "Well, I don't think so... they just look alike..." "Ma-kun, were you squeezing with this woman?" "Wow, I'm so happy!" Eh...///” (Tukun) Yuria, the normally plain-looking stepmother, turns out to be a legendary superstar AV actress! I'm so happy that I pulled out an erotic costume and started a private lesson for Mr. Ma! From the first blow job to the gold ball sucking, the vacuum blow job suddenly explodes and cums in the mouth! "Oh, I've already put out so much ...". After that, my virgin friend Yamamoto-kun also got involved and I spent the days of gifted SEX education. I kept squeezing until the sperm dried up with serious sex with my mom.
