A virgin college student misses the last train and ends up staying at the home of a single gyaru mother where he works part-time. He can't resist the big black ass he's been staring at while at work, so he tries to have sex with her right away, but he's too much of a virgin and it doesn't work. He makes up his mind and begs her to take his virginity, and the generous gyaru mother is hesitant but agrees! Busy with work and raising a child, it seems it's been a while since she's had sex, so he gets hooked on his virgin dick! He keeps having sex so much that he uses up an entire box of condoms by morning, and cums inside the single mother until she's satisfied...!
