Discreetly, I slip into my girlfriend's room, her scent lingering in the air. I spot her panties, still damp from earlier, discarded on the floor. The sight of her pussy's outline on the fabric stirs my desire. I can't resist, pulling them to my face, inhaling her musk. My cock hardens, and I stroke it, imagining her wetness. I push her panties aside, my precum mingling with her juices as I fuck my fist, grunting, until I explode, staining her panties with my cum.
