My wife and I were married a couple years with no kids, enjoying ourselves to the fullest, in every way possible. We rented the upstairs of a large, 2 family house. Corrine lived below us. The same age as we were, she was a divorced mother of three (really awesome) kids. We had shared this living arrangement for a few years and, as is common with shared spaces, privacy is at times, tested. As is discretion.
In time we got to know each other. Over a year or so we learned a lot of personal information about each other as well. One poignant bit of information was that Corrine and her ex were swingers, as were we! Although we did circulate in different crowds so we never met up in any of the clubs that either of us went to. We knew that she was in the lifestyle, and she knew that we were in the lifestyle as well. The funny thing is we never really spoke about it with each other. Any interest in consequence of us knowing such a personal details about each other was a definite sense of a relaxed atmosphere about each other. To the point that one afternoon while my wife and I were puttering about in the backyard Corrine Came outside to ask us a general question about things and make some small talk. Not unusual for her, she was wearing her bathrobe. Although during the conversation this time the top of it kept loosening. I was treated to a wonderful boob show! One thing I've always admired about her were her fantastic tits! During the conversation that robe kept on opening and my eyes kept on wandering. I am positive she caught me because at one point in the conversation, after what I thought was a clandestine glance at her chest, she flashed me a sly grin and a wink. After that secretive interaction I swear that robe never was adjusted closed again for the rest of the time!
Things with Corrine heated up one evening while my wife and I were making love. We were on a kinky run at the time. Both of us on our backs with my wife fucking me. She was holding my ankles to her shoulders, her strap-on sliding its full length in and out of my ass. While getting hot and heavy, she urged me on by telling me to start using Corrine's name. We often fantasized having three ways with her. So the request wasn't really all that unusual. One thing that was different was that we knew for a fact she was home... alone; the kids were out with Dad. Also, we heard signs of life from below; the unmistakable sounds of her closet door squeaking, bed creaking, television babbling. We also knew she was laying on her bed exactly below us (Corinne was a loud talker on the phone).
Just to try something different, and to see what my wife's reaction would be, I groan out her name, "Mmmmm yeah Corrine". After a few strokes more in and out of me, she tells me to repeat her name, "but this time really mean it baby. "
Then again, but louder. We knew one way or another, there would be repercussions if we continued down this path. Still; yet again she demanded I invoke Corrine's name. We were, once again, imagining her with us. I comply by moaning and mewling her name, begging her, "Please peg me Corinne! Yeah baby! God I love it Corinne!" Soon I look back at you, just to see you full of lust and grinning while fucking my ass! I was able to moan, "Your turn, My Love." My wife didn't miss a beat. "Yeah Corrine! Fuck my husband baby! Do him Corrine, make him your slut!" Before long we both are moaning for Corrine. Saying her name again and again as we share our visions of her joining with us.
