The day I visited my beloved girlfriend's house, a busty, horny older sister suddenly started seducing me with provocative words. Though it was our first meeting, she approached me boldly, unlike my shy girlfriend. She was gentle yet erotic, and while I was drawn to her charm, I couldn't help but remain conscious of my girlfriend's presence. With my girlfriend, condom-only sex was the rule, but the older sister allowed bareback and creampie—her free-spirited style was irresistible. Despite being right beside my girlfriend, the raw sensation with her sister was extraordinary, so intensely pleasurable that I couldn't stop thrusting. Overwhelmed by the older sister's seduction, my desire surged uncontrollably.
