"Please Jimmy we have to stop" Grant insisted hating the petulant whine that crept into his voice as he spoke, "I'm your father for God's sake!" "Oh really?" The younger man asked with a wicked grin "You don't much look like it from where I'm standing." Grant felt his son's fingers tangle in the raven tresses of his hair. Pulling his head back until he was facing his own beautiful reflection in the mirror. "My father was in his fifties. Mostly bald, about twenty pounds past heavy set and more importantly a man. Tell me, do you see anyone here that matches that description?" Grant shook his head trying to deny it even as the girl in the mirror copied his every motion. "Jimmy, son, try to understand," Grant begged once more "all this is only temporary. Once I get the parts for my machine..." His pleas dissolved into whimpering moans as Jimmy's thrusting cock found the entrance of his cunt.
