Grandpa, hairy and confident, lounges naked, his thick cock hard and eager. John, a twink with a straight reputation, enters, nervous yet curious. The grandpa smirks, "You're here for a reason, aren't you, boy?" John blushes, his cock tents his boxers. He hesitates, then strips, revealing his smooth, toned body. Grandpa groans, "You're fucking gorgeous." He pulls John to him, their cocks rubbing. John gasps, his first taste of a man's cock as Grandpa feeds him his length. Soon, John's on his back, legs wide, as Grandpa lubes up and enters him raw, the twink's eyes widen in pleasure-pain.
