In the dimly lit room, Marcus and Dex stand, their bodies tense with anticipation. Dex, holding a bottle of lube, smirks at Marcus, "Ready for your gift, son?" Marcus nods, his heart pounding in his chest. Dex lubes up his thick, veiny cock, the sound of his hand stroking up and down echoing in the room. He turns Marcus around, pushing him down onto the bed, and spreads his ass cheeks. Marcus tenses as Dex presses his cockhead against his hole, then relaxes as Dex pushes in slowly, filling him up. Dex begins to thrust, his hips slapping against Marcus's ass, the sound of their bodies coming together filling the room. Marcus's moans grow louder as Dex picks up the pace, his big cock stretching Marcus's hole, their bodies slick with sweat.
