The room pulses with the rhythm of their desire, the scent of sex heavy in the air. Robert's girlfriend straddles him, her hips grinding against his hardness. She unzips his pants, freeing his cock, and strokes it, her thumb swirling over the tip. He groans, pushing her panties aside and slipping a finger inside her. She gasps, her head falling back, her hair cascading down her shoulders. He guides her onto his cock, her tight pussy enveloping him. She rides him, her tits bouncing, their bodies slapping together, until they both come undone, their moans filling the room.
