I went on a hot spring trip with my best friend's couple, but while my best friend drank too much and fell asleep, his girlfriend started complaining, "This guy is cheating on me!" and pushed me down, saying, "I'll do it too! Let's have sex!" She said, "Look, if you say you will, I'll put it in like this?" She rubbed my dick directly against her pussy, seducing me from a distance! I felt guilty, but I cheated on her right next to her boyfriend! I fucked her like crazy!
