This morning got me so worked up! I was fingering myself when my sister's guy unexpectedly walked in. Damn, I was startled, hurriedly covering up all my intimate spots. It was too late, he caught a peek. I felt awkward, yet I couldn't help noticing his hard cock tenting his pants. My mind spiraled with dirty thoughts, imagining his throbbing rod entering every inch of me. I could sense the tension, aching for us to give in to our lustful desires. So, what do you say we act out that naughty scenario together?
