Hajime is feeling down after his first girlfriend scolds him for being terrible at sex, almost breaking up. His busty gal childhood friend Moka shows up, offering to teach him how to handle her boobs. He takes her up on it, practicing her "How to" instructions. As he gets carried away, Moka starts to let out moans, and before he knows it, he's ditching the "How to" and stripping off her panties. It's a meddling, horny gal's rescue sex lesson.
