The first time I went to her house, the person there was her super beautiful and sexy older sister (the eldest daughter). She opened her legs and showed me her panties. This was clearly an attempt to seduce me. And even though she was nearby, she started to play with my excited dick so that I wouldn't be noticed, and even made me cum! The beautiful-legged and experienced slutty older sister seemed to like me, and she continued to play with me, and I ended up crossing the line next to her. Because I can't stand this!
