My girlfriend's older sister wasn't wearing a bra and was unsuspectingly seducing me, pointing her breasts at my crotch. (Hirose Hina, IPX-877)

Was it recklessness? Was it deliberate? My girlfriend's older sister exposed her breasts to me. Her incredibly sexy breasts, always braless. Absolutely soft G-cup breasts. Her erect nipples were clearly visible even through her clothes. How could I possibly resist…? "My breasts are bigger than your sister's, right? I'll give you a milk cannon!" Those were dangerously attractive G-cup breasts. And so, I was repeatedly manipulated by my sister, whose sexual desire and arousal fueled by stimulation and sex.
