Me and my wife of 15years, Fay, were discussing our friends marital strife. Ben had come home early to find his neighbour Mohammed happily jizzing over ben's wife's face. She blurted out sorry accidentally spitting spunk into Bens eye. Not a happy time but he decided to forgive her and they are trying to move on. Anyway, Fay asked me how I'd feel if she had sex with someone else. Fine I replied, as long as I can watch. She laughed. Kinky bastard she said. It would be Brendan I suppose, I asked to which she sulked as I'd often accused her of going with Brendan despite her constant denials. Later in bed we got horny talking about group sex and infidelity and rounded it off with a great fuck. A few nights later I was having a consoling beer with the still distraught Ben. Although tortured he kept reliving the sight he'd seen which suited me because the thought of his wife covered in another mans cum aroused me. Then I got a text from Fay that said. Hurry home I'm horny. I couldn't walk out on a mate in need so it was 2 hours before I got away. As I walked up the path I saw the bedroom lamp on. A sure sign that Fay was still awake and ready for cock. I tore my clothes off as I climbed the stairs. There was my wife on the bed, black stockings and suspenders and heels. What surprised me was she was on all fours with Brendan hanging out of the back of her. She smiled through her misty cum eyes. I couldn't wait she said. I went semi as if my cock couldn't decide how to compute this scene and Brendan just remained very still, hands still resting on her round black ass, wandering how I'd react. Fay tutted. Come on she growled at Brendan grinding her arse back against him. He resumed pumping into my wife glancing nervously up at me. My cock decided it liked the show and stood proudly to attention. Fay laughed at the view saying you really are a kinky bastard, I'm being fucked and you like it. Brendan said fucking hell Fay he's huge. Again she laughed. Why do you think I've been with him so long? She reached back and kissed him. Fuck me harder. He obliged slapping his balls up her fiercely. Finger my arse she whispered hoarsely. I know my wife very well. I could tell she had already cum several times and was about to again. I found myself wanking my raging hard on. She came noisily and slumped forward onto the bed. Brendan went to withdraw but I said Leave it in mate. Fay likes the cock to stay in after orgasm. Thanks she smiled at me, he keeps doing that. She looked so beautiful, I moved forward and offered my erection to her mouth but she just kissed the tip once and said we've moved on from the foreplay. She moved forward and Brendan fell out of her revealing that he was indeed quite poorly endowed. He was also bare. Maybe it's our 15yr relationship that made me know what was next. Fay had enjoyed anal with her ex but found me too big for her so I just stimulated that area with fingers. Brendan nearly choked and I thought he'd spurt when Fay demanded. Fuck my arse Brendan. He looked around desperately for lubricant but Fay demanded just shove it in. Her delight at finally having a man up her arse after so many years was beautiful to see and I settled back on the bed to enjoy watching my wife sodomised. I didn't expect what happened next tho. She deftly manoeuvred around followed by poor Brendan struggling to keep his little cock in her. She straddled me and gripped my cock slowly impaling herself and then she fucked me. Brendan's balls slapped against mine as he continued rutting her arse. I was amazed at his restraint although it transpired he'd already seeded her cunt earlier. I managed to hold on until I saw the telltale signs of fays impending orgasm and me and her came together. I blasted loads of hot cum into her willing hole. We lay in contented bliss rocked gently by Brendan's continued arse fucking. As I softened and slipped out he was keen to take my place and his thrusts took on more urgency as he fucked her cunt from behind. She lay in my lap gazing lovingly at me. She wouldn't be unkind enough to say but I knew Brendan's cock wasn't doing anything for her now she'd cum on mine. But she lay patiently as he fucked away at her as hard as he could until eventually his ball content joined mine in my wife. I could tell now that she had never fucked Brendan before and wouldn't again but it was a great experience for all three of us. Oh and that night I phoned Ben. "You'll never guess what mate....
