Christmas 2014. My wife was at her mothers Christmas eve. I was at home banging a young guy I'd been fucking for some time. Just as I was pumping my load up his arsehole, my saintly fucking sister walks in. I'd totally forgotten I'd given her a key, and there she was staring at me balls deep up my young friend arse.
Not a problem you would think, after all she is my sister. Thing is, she's also best friends with my wife. My sister gets all holy on me, saying how could I cheat on her best friend and with another guy, especially on Christmas Eve. As if the stupid bitch actually goes to church or something.
To cut a long story short, my wife's back home half an hour later and I'm packing my bags. My young friend had already left (With an arse full of my cum). Then for over half an hour I took abuse from my wife and my, I've never done anything wrong in my life, sister.
Moving on to a month ago. I'm in my small flat where I live alone (And ocassionally fuck my young friend) when I hear the door bell ring. Opening the door I see it's my sisters husband Gary. I asked him what he wanted and let him enter when he said he had something private to ask me.
Also cutting this short, because it took some time for him to finally ask me, but when he did he wanted to know, and get this, what it was like to have sex with a guy.
Gary is what we call a mans man. Big, muscular and known in the area as a hard man. So hearing him wanting to know about gay sex, was like listening to a racist white upper class mother, wanting to know if her prissy little daughter was taking a ten inch black cock up her c**t.
The conversation eventually got round to the fact, Gary had been sexually experimenting with his wifes, my sisters didlos (Not such a saint then). Dropping my loose fitting indoor lounge shorts and revealing all of my eight inch splendour to Gary, I had him sucking on my cock within a minute. Taking a now naked Gary, sporting his six inch erection into my bedroom. Where only a few hours before I'd fucked my young friend (Would still have had some of his anal juices on my cock when Gary was sucking it, come to think of it). I got Gary to kneel up on the bed as I gently at first, inserted my erect condom covered cock up his arsehole.
My young friend (He's eighteen by the way) can take cock up his arse quite well, but Gary after an initial doubt over the pain, was a complete cock slut. I'd cum earlier, so fucking my brother in laws arsehole lasted a long time. And didn't Gary enjoy it. His cock was throbbing by the time we'd switched position a few times and I had him on his back with his ankles on my shoulders.
Surprisingly, to me anyway, I came first, but Gary asked me to carry on fucking him as he was close to his orgasm. So with my cock softening, I carried on fucking my sisters husband, until his cock erupted like a fucking volcano. His cum sprayed everywhere, as each pulse of his ejaculation spewed out more gooey white stuff.
Before Gary walked out of my flat, he asked me not to say a fucking word. Not that I would.
It's strange Gary calls by every couple of days now to have his fun with his brother in law. I don't always fuck him as I have him doing all sorts of nice things sexually for me, but that's for another confession, maybe if my sister ever finds out.
As for her and my wife, It appears from Gary, they're very close now. Wonder if like me, my sister is having it away with my ex other half.
