Adult performer Aya Eikura returns to test the claim that small breasts are more sensitive than large ones. Pale and slender, she has pert little breasts, prominent nipples, big eyes, a small face, and long limbs. Her partner is an older man who enjoys humiliation play, and her uneasy expression shows as she struggles to give his cock a titjob with her small breasts. When he penetrates her deeply, her body responds and her nipples turn fully erect. He finishes by filling her with cum, proving just how sensitive and eager for sex this small-breasted adult role-play character can be.
