When my husband Ian and I visit his younger sister (Which we do once a month), I know one of three things will definitely happen. Ian and his sister Susan will get themselves steadilly drunk at the pub we always visit when we travel to Susan's and Colins . They'll then get smashed out of their heads on rum and coke, when we get back to Ians sisters house. They'll both either crash out downstairs, or preferably if Colin, Susan's husband, and I can manage to lift Ian upstairs, we'll put them both to bed.
The final thing which will happen, is Colin and I will go into the basement of his home, where he's built a home cinema, and fuck one one anothers brains out. And the reason for this infidelity, both Ian and Susan are incapable of satifying either one of us sexually anymore. They've both turned into piss heads and enjoy alcohol more than sex, so every time I've visited since 2011, myself and Colin have made time to have as much horny dirty sex as we can.
Once Susan came downstairs as her husband was fucking my arsehole from behind. She shouted down to Colin and me to see if we wanted a drink. Colin answered as he rammed my rear fuck hole, by telling his wife "I'm more thasn taken care of Thanks".
Another time when we couldn't get Ian upstairs and there'd been a leak in the basement. I had Coiln fuck me only feet away from my snoring husband. It was so much fun at one point, to have Colins large thick cock pounding my pussy to the same rhythm my husband was snoring to.
We're going again this weekend and Colin has told me, he's bought a reasonably expensive bottle of rum for them to share. It's also a spring festival in the village they live in, so the pub we go into is having a cheap beer night. It can only mean one thing. They'll get pissed up and I'll have a fantastic weekend being fucked by my brother in law.
