Mizuhara Misono, Arioka Miu, and Haruna Noa infiltrate a men’s massage parlor rumored to employ only huge-breasted therapists.

When the stimulation makes him accidentally cum, they climb on top and use their voluptuous bodies in grinding cowgirl to drain him repeatedly, leaving him completely spent.
