In this adult school-club role-play, a quiet, bespectacled student with enormous J-cup breasts studies the male body through hands-on practice with her teacher so she can draw better erotic manga. She transforms into an insatiable researcher who licks his balls, nipples, and armpits, wraps his cock in titjobs, rides him while her breasts bounce wildly, and holds him close through thick creampies in multiple positions. Every ejaculation is merely more reference material, and although he knows he should stop her, he cannot resist her soft, voluptuous body or her runaway curiosity.
