Last Sunday we had glorious weather here and whilst I got cracking on some jobs on the house, my wife J took the chance for some indian summer sunbathing. She rarely sunbathes completely topless, usually undoing her bra and part covering her very generous (36EE) chest. She revealed a bit more than usual because, as she said, it would probably be the last chance before winter. By mid afternoon I needed to pop to B&Q for a few bits and left her to it. When I got back I was desperate for a pee so went straight upstairs to the bathroom. As I relieved myself I could see J in the garden, now fully topless, talking to one of our neighbours. This guy has always been very friendly, if a little pervy and J is pretty certain he has spied on her in the past. It was obvious he was eyeing her up and she was quite clearly enjoying the attention and flirting away quite merrily. I finished off, flushed the toilet and watched him scurry away as he obviously heard me coming out to the garden. I didn\'t mention what I had seen and, telling J I was just going to finish a couple of jobs inside, I dashed back upstairs to the bathroom - only to be a bit disappointed that our neighbour did not reappear. That soon changed when J started to slowly massage herself through her knickers. With her eyes closed it was clear that she had been really turned on by being caught topless and she was feeling particularly randy - and I didn\'t seem to figure in her plans! She carried on like this for some time, then thrust her hands down her knickers and really went to town - rubbing her clit and shoving her fingers up herself. She soon started thrusting her hips upwards, then tweaking her nipples as I could tell she was building to her orgasm. Pretty soon she just lost it, fucking herself with her fingers and pulling on her tits and nipples, legs wide apart and eyes tight shut. She came with a loud moan and continued to shake from what must have been a huge cum. By this stage I had my prick out and had been wanking for all I was worth and shot a load all over the bathroom. By the time I got it all cleaned up and went back downstairs she seemed back to normal and even had her tits part covered. The thing is, she must have known the randy old sod of a neighbour would have been watching her and the dirty madam was clearly putting on a show for him. I have a feeling there may be a few more developments that I need to keep an eye on!
