MFYD-212 | I ran into a neighbor while out jogging—she was so incredibly sexy that we ended up having tons of sex at her place while her husband was away. — Rei Saegusa

Why are Rei Saegusa’s sweat and sex so incredibly erotic? With her long legs, a firm, shapely backside, and breasts that practically spill out of her sports bra—Rei, who has been married for a few years, decides to take up jogging (partly to relieve the sexual frustration from her sexless marriage). One day, while out for a run in the park, she ends up getting intimate with a college student who’s an athlete. It turns out I just love working up a sweat during sex…!! Rei’s pent-up sexual desire explodes! From that moment on, Rei Saegusa’s “runner’s high” sex life only continues to escalate—and there’s no stopping it now…!!!
