Most weekdays Greg calls by our home and expects my asshole to be ready for him. He never stays long and wants me naked, lubed and kneeling up when he texts he coming over. His cock is invariably rock hard by the time he reaches the bedroom, and within seconds of him entering, he's usually driving his long thick cock up my asshole. Gripping my hips, he fucks me SO hard and so deep, I'll normally cum within five minutes. As he tells me I'm his bitch, he'll grind right into my hole and then his cock will explode spurting his hot liquid far into my bowels. Pulling out, he'll tell me if he might be round the following day. I'll hear him getting himself sorted out and listen as he drives away from our home. It's something that has been happening for the last eight months or so, ever since he caught me tossing myself off to gay porn. He'd called by to see his daughter, but discovered his son on law masturbating to gay sex and saying "I wish that was my ass". From that day to this, my father in law Greg has been fucking me whenever he wants, and I love it.
