Sharing His Ass

Where I work, there's a young nineteen year old guy called Eric, who just loves sucking cock and being fucked.
He's a complete fuck slut who at present has three guys sharing him.

We all know he's being fucked by all of us, and sometimes we do get to fuck him together.
But mostly throughout our working day, we'll have Eric suck us off, or if we have enough time, we'll fuck the little cock loving bitch alone.
I'm lucky enough to have a completely private office apart from the main building, and it's in there I fuck Eric, nearly every day.

Some days I'm first to use his butt hole for my pleasure, but mostly I'm second or even third. And I just love those days.

There are two main reasons why I enjoy sloppy seconds or thirds. Partly because my dick is a lot bigger than the other two guys. But mostly it's because I adore licking his asshole when it's full of their cum. In other words I really enjoy felching Eric, before I fuck my junior colleague.
It's been a fetish of mine ever since I began fucking a friend at school. He would always have me tongue him clean after I fucked him, so his parents, or anyone else wouldn't see his cummy boxers.

It was a similar situation with a football coach I was fucking. I'd fuck him in his truck mostly, then give his asshole one hell of a tonguing so his wife didn't know a teenager was screwing her husband.

The other two guys at work don't know I have the fetish, but I have once in a motel room, serviced Eric's fuck hole after they've fucked him.
Luckily they had to leave to get home to their wives. I don't have that problem, so spent an absolute age fetching Eric.

I'm not sure why it's such a horny kink for me. What I do know, is my cock becomes super hard and strains for an ass to fuck. And Eric invariably benefits from my length being so horny for his slut holes.
