My girlfriend isn't drop-dead gorgeous but she has a great personality. We've been together for six months now, and when I went to her house for the first time, she introduced me to her older sister. Her older sister is a total knockout; stunning looks, incredible figure, and H cup breasts that seem to be begging to pop out of her clothes. For some reason, she was braless both times we met. One day, I had to go back to her place to retrieve something I left behind, and there she was again—older sister, braless, with those massive tits pressed against my chest. I tried to hold out, but my dick reached its limit and became fully erect before I could stop it.
