Jerry dug his fingers into Heather's hair and looking down at her he marveled at the sight of his cock disappearing into her head. He started gently swaying his groin into her and she soon was moving her head with the motion. Her mouth felt like heaven wrapped around him, years of fantasy turning into truth. It was actually happening, he thought, I'm actually naked in the shower with my naked, lovely cousin, and my cock is deep inside her lovely mouth. And this is just the beginning.
He felt his body swinging faster and his fingers gripping her head tighter, and the more Heather's fingertips dug into his ass the more energetic they became: Her sucks attempting to vacuum up his cum and his cock scrunching in time and reaching for the depths of her throat.
