Popular plan where an amateur wife is given one condom and stays overnight at a college student's home. G-cup wife Maki, deeply interested in the younger, naive reactions, leads and puts on the condom for sex. After sleeping together, they feel like doing it again, and the college student asks if he can pull out if allowed to ejaculate outside. However, he accidentally ejaculates inside. Nonetheless, both enjoy it so much that they get hooked on the intense, messy sex with internal ejaculation.
