In a private moment, a young man donning a pair of his sister's panties finds solace in his secret ritual. He caresses the silky material, feeling the cool fabric against his heated skin, his cock throbbing with anticipation. Slowly, he slides a hand beneath the waistband, wrapping his fingers around his engorged shaft. He strokes himself, his breath hitching as he builds a rhythm, lost in the fantasy of a forbidden touch. His body tenses, pleasure coursing through him as he nears his release, the panties dampening with his excitement.
