I have a girlfriend that I really like. One day, when I went to her house to play, there was a sister who had bigger breasts and more sex appeal than my girlfriend! Even with my girlfriend nearby, the sister didn't care and squeezed my dick between her breasts, sucked it with her mouth, and even inserted it into her pussy. Although I felt guilty towards my girlfriend, such a happy temptation and the situation where we might get caught made my dick hard as a rock! Moreover, she agreed to let me cum inside her, so I kept cumming inside her!
