The first is Minayo, a Ke'ai young wife with fair skin and plump H-cup breasts. She works part-time at a karaoke bar during the day. She is invited to the house by a student who comes over from time to time, and out of curiosity, she follows him, but when he shows her his erect penis, she allows him to insert it! The second is Mami, a cool married woman with a bob haircut. She is curious about a student who works part-time with her at the company where she works, and seduces him and goes into her house. It turns out that he masturbates every day and it's been several years since he's had sex with a woman. She licks his erect penis, which is so hard it's about to burst, and allows him to insert it raw.
