Daddy's calloused hands, rough from years of labor, contrast starkly with the son's smooth, sensitive skin. As Daddy's fingers dance along the son's inner thighs, the son's cock twitches in anticipation. Daddy smirks, knowing the effect he has, and slips a finger into the son's mouth to wet it. The son sucks eagerly, his eyes locked onto Daddy's, before the finger is withdrawn and slowly, teasingly, pushed into the son's ass. Daddy's other hand grips the son's cock, stroking it in time with his finger's thrusts, driving the son wild with desire and shame.
