In the privacy of my room, I spread out my neighbor's discarded panties, their delicate fabric a stark contrast to the crude, lewd thoughts running through my mind. I'm alone, but the thought of her makes my cock twitch. I stroke myself, my grip tight, matching the rhythm of my fantasies. I imagine her wearing them, her hips swaying, her wet pussy leaving traces on the fabric. I groan, my pace quickening, my balls tightening. I cum, my hot seed splattering onto the panties, marking them as mine. I collapse, my body shuddering, my mind filled with the scent and feel of her.
