Half a year of dating had been a crucial period for deepening my relationship with her. She seemed ordinary at first glance, but her gentle, warm personality made every day enjoyable. When I was first invited to her home, she introduced me to her older sister. Her sister was a flawless beauty with an incredible figure. I'd heard her breasts were a size H, but seeing her in person—braless, with her massive tits nearly spilling out of her clothes—my eyes were instantly glued to her. Later, I had an excuse to return to her place to pick up something I'd left behind, and once again, only her older sister was there. Still braless, her huge breasts pressed against me, and gradually my heart began to waver. In that moment when I reached my limit, my cock became fully erect.
