Sex was new and exciting again, especially the sex Alice and I had with each other after our various playmates went home.Well, after abut a year of sw...pping partners, Alice found herself talking with a man named Alan who referred to himself as a 'Bull'. He wanted to talk to us about cuckolding. He said that it added a new dimension to swinging and wanted to meet to discuss it.Now Alice and I had usually swung in separate bedrooms but I'd always wanted to watch her with another man without the. She pecked her ‘uncle’s’ cheek and grinned at him. It had been too long since she saw this man. Far too long. ‘Hey you’ he winked holding her up and around his waist, in a seemingly innocent position. ‘Been waiting here for a couple of hours, your dad got asked to extend his business trip so asked me to hang about and keep an eye on the place while he was gone… I knew he forgot you were due home today, don’t mind the company till he gets back, do you?’ ‘Awh really? Well that sucks about Dad,. Since very long, we had not met and fucked so this story is about what happened when we met after a while! My sister had to switch the city and had to go to Delhi from Pune for some job interview. I being a good and responsible brother accompanied her on my dad’s instruction. I was so happy to see my dear sis again as I knew I could have a chance because she strictly denied sex last time we fucked. Actually, she had a boyfriend and was having regular sex with him. And here, I was frustrated and. Up on my hands, her nibbling at my right nipple and sweat pouring off both of us, my cock was going mad, he just had to cum.We have a lot of sex, but somehow this was different, different in as much as she was taking the lead and definitely needed to rut, every part of her body was screaming ‘FUCK ME’ and her pussy was clutching him so tight, the ribs up inside her were going to make him cum.I rolled over onto my back taking her with me, I grabbed a hold of her arse, pulled those little cheeks.
