Riho, a mother, was worried that her daughter's boyfriend didn't use a condom when they had sex... When she gave him a box of condoms while her daughter was out, he asked her to teach him how to use it, so she taught him how to have sex with a condom for her daughter's sake. She only intended to teach him how to use contraception once, but... she got hooked on his young, hard cock! Riho becomes a woman again every time she has sex with him... They have sex over and over again until the box of condoms is empty, and in the end, she even cums inside him raw...!
