Her panties, a silent invitation, a secret I dare not share. I slip them on, the cool cotton against my skin, her scent enveloping me. I stroke myself, the taboo nature of my act sending waves of pleasure through me. I imagine her finding me like this, her shock, her anger, her... desire? The thought pushes me closer to the edge, my cock pulsing, ready to release into her panties, claiming them as mine.
