My girlfriend, a busty older sister with H-cup breasts who wasn't wearing a bra and was unguarded while getting inflated, lost to my overwhelmingly seductive and worst self. (Yami Rin FSDSS-671)

I have a girlfriend I adore. The first time I went to her house, there was a stunningly beautiful woman with enormous breasts... and she wasn't wearing a bra!? The moment I saw her, I fell in love... When I saw her sister's enormous breasts, my lust overcame my love for her. Seeing her exposed breasts in her loose loungewear was incredibly arousing!! No man in this world could resist placing his hands on those beautiful, large breasts! I fondled her swaying breasts and did what my girlfriend and I couldn't do—nipple sex... Even though she was right next to me, my reason went mad!
