Fuck Slut

He's my own personal eighteen year old fuck slut.
Every time I want to empty my balls down Gareths throat or up his beautifully tight rear fuck hole, it's all mine.
There hasn't been a day over the last eleven months where I've not fucked him. And Gareth just loves the rough hard sex I give him.
He moved into my home, after his mother's new husband and he argued over his gay needs.
His mother, my sister, doesn't say anything, but she knows I'm fucking my nephew.
Gareth is a slut, and knows it. But then so am I in terms of enjoying his beautiful young body.
Gareth will be possibly moving out to go to university in September, but until then I'm going to carry on fucking my nephew.
If he does leave, I've already begun enjoying another young man. He's Gareths friend Robson, and he's also a passive gay young man.
I haven't fucked him yet (Gareth) but Gareth has had him suck me off a few times.
My nephew has already suggested to Robson he should move in if he goes to uni.
