Grandpa, a grizzled veteran of the gay scene, welcomes two eager twinks into his lair. The lads, barely legal and smooth as silk, tentatively explore each other's bodies before Grandpa takes center stage. He strips off, revealing his throbbing, uncut cock, and the twinks exchange a nervous glance before diving in, their tongues eagerly lapping at the veteran's shaft. Grandpa groans, guiding their heads as they take turns sucking him off, their hands exploring each other's asses, fingers probing tight holes.
