The story is, I'm married to a lovely wife and we have 3 children. We have a great sex life and always have done. We've always liked to talk about having other people join us but nothing has ever happened. Recently my wife has joined a gym and started doing some training with a personal trainer called jack. He's only early twenties but apparently very good at his job. Unfortunately I've suspected young jack has been tucking into my wife. I suspected for a while and did mention it to the wife but she just laughed it off. Anyway I went to work supposedly but went and had a cuppa around the corner in the local pret knowing the wife goes to the gym about ten. I went home and as expected wife out. I hid in the spare room and waited for about 20 mins then heard the door open and voices, the wife had brought home her trainer, bitch!! Well I froze as I heard them make there way upstairs. He was saying how much he'd been looking forward to fucking her brains out all weekend, she was saying how much she'd been thinking of him fucking her. Although very angry I found myself very much turned on. Any way it wasn't long before they were at it in our bed, cheeky bitch. I looked in and saw an absolute monster cock going in and out of my wife's pussy, and she was loving it. He was fucking her doggy style really deep and hard, she's normally vocal when getting fucked and she was even louder with this I reaction 8 inch cock pounding her. The cheeky little fucker kept saying how did she like being fucked by a big cock!! She was saying more than my maggot sized husband!! I'm 6 inches and thick, but was really in envy of this young hard cock which was giving my wife pleasure I couldn't!! So I left them too it and waited until they finished. It wasn't long before he left. I went into the kitchen and asked the wife how long it had been going on, she said about a month and she'd stop if I'd forgive her. Bollocks I said do as you want, I've been fucking my secretry for the last two years. Happy fucking days!!!
