This is a follow up to Straying wife from 23 July which you might like to read first. She worked late again last week - apparently! Came in at around 10.30 and announced she had gone on for a bite to eat with a couple of the girls from work - then she headed for a bath and bed. I tried it on with her when I joined her in bed, but she was too tired. The next day she set off for work and I rummaged around until I found her knickers from the previous night. There were clear stains on them as evidence that she had been well and truly spunked the night before, so I was left with just 2 things to do: Firstly I had to have a wank into them. Just the thought of what she had been up to had given me a raging hard-on which I released, wrapped her knickers around and wanked myself stupid. It didn't take long for me to add my spunk to his and I put them back where I'd found them. Secondly, I had to confront her and find out what was going on. When she came in that night she went to put her washing on and came in, holding her knickers, and asked me what the hell I had been up to - wanking in her knickers! I went mental: "what do you mean what have I been up to, what have you been up to is more to the point, mine's clearly not the only spunk on those knickers!" "You stupid man, you don't really think you would have found them if I didn't want you to?" I was dumbstruck, what the hell was going on and how have I lost control of this? It turns out she had seen my car in the car park the previous week - just as she lowered herself onto his cock - and realised that I was watching but not stopping what she was up to. She said that she found it a massive turn on to know that I could see her getting shagged, could see her tits bouncing up and down as she rocked back and forth on his cock, could see the look of ecstasy on her face as she came and knew the exact moment that he unloaded into her. She asked me why I didn't stop her and I had to reply that it was because I had found the whole thing as sexy as hell and had been wanking myself whilst she was shagging. We just stared at each other, then both started grinning at the same time. Before either of us really thought about it, we were all over each other and before long she was bouncing up and down on my cock in the front room, curtains open so anyone could see in. I kept calling her a slut, bitch and whore and she just called me a dirty little wanker - we both came very quickly and lay back to catch our breath before talking the whole thing through. The upshot is that she now has permission to shag him, but must let me know when it's likely to happen so that I can watch surreptitiously, then come home and tell me all about it whilst I add my spunk to her well shagged cunt. It's very early days and nothing has happened as yet, but we can't keep our hands off each other at the moment, so long may it continue!
