When I went over to my friend's house to play, I panicked because I couldn't find my phone. Hey! Did you maybe put it somewhere? As I was asking around like that, his little sister started smirking while rolling up her skirt... there it was, my phone! And she wasn't wearing any panties either! What's going on here? I thought, feeling confused. But before I knew it, the teasing escalated further, and I just couldn't resist anymore. Despite telling myself not to give in, my arousal got the better of me, and I finally crossed the line, succumbing to temptation as I became fully erect.
