By this time, we had been together quite a while. Pete and Donna had had a baby who was now about 18 months old. We had a child as well... he was about a year old, so both mums had a lot in common.
Donna and the toddler had come up to visit us for a week or so, leaving Pete at their house, with strict instructions to complete a long list of DIY tasks - or else.
Our home was a chalet bungalow, which we were renting in the Herefordshire countryside. It had a nice room upstairs, immediately above our bedroom. So we made up a bed for Donna up there, and put a second cot for her kid in the spare room downstairs, so the two children could sleep together. The house was a cheaply-built '70's construction, so the floors and walls were paper thin - meaning there wasn't a great deal of real privacy.
The thing was, I'd always quite enjoyed teasing Donna. It had always been pretty obvious that Pete was unable or unwilling to really satisfy her highly-sexed womanly needs. She would constantly complain and say things like, 'I've tried dressing up in stockings and suspenders and everything, but nothing works!'
Conversely, I had acquired something of a reputation for being 'Good in Bed'. There was a time at the nurses' home - I was staying overnight with Laura and was at the sink, cleaning my teeth, wearing nothing more than a pair of skimpy black briefs. If I do say so myself, I was in pretty good shape - years of hard manual work had given me a good physique, well defined muscles and a trim waist.
Donna came barging in through the door on some pretext, but stopped dead in her tracks, eyeing me up and down. Laura and I had just been fooling around a bit, so I was still sporting a semi hard-on and was packing quite an impressive bulge in those briefs. If Laura hadn't been there, I'm sure Donna would have gone for it, right there and then.
When Donna was staying with us, Laura coincidentally had one of her hormonal horny nights. I was fucking her hard, first missionary, then doggy, on our double bed, right below where Donna was 'sleeping'. Laura could be quite vocal when we were having sex like this and I knew perfectly well that Donna would be able to hear all the passionate noises and groans. I made no effort to be quieter - smiling inwardly, the exhibitionist in me knew that our amorous activities would undoubtedly be turning her on. 'Guess what, I'm getting laid and you're not!'
A moment later, we could clearly hear a buzzing noise from upstairs... we both realised, Donna was pleasuring herself with a vibrator! I was astonished when Laura came out with, 'D'you know, it would really turn me on to watch you making love to another woman? I'd love to watch your cock sliding in and out of someone else.'
Gulp. How do you answer that? I gave a rather non-committal reply... 'You do realise that's every bloke's favourite sex fantasy? To have another woman in bed with them and their wife?'
Next, she is saying, 'Do you want me to go up and invite her down here, then?' She gave me a nudge and a sexy grin. 'She's obviously really frustrated.' That was one of those really difficult situations, where you don't know if she actually means it, whether it's some kind of fidelity test, or whether it's just sexy pillow talk. The thought of fucking a frustrated, horny bitch like Donna, while my wife watched, was incredibly erotic. I desperately wanted to say, 'Yes please! Go fetch her and I'll fuck her brains out while you watch! (and hopefully, you join in!)'
But I figured it was just some kind of sexy game, to get me going, and I replied with something really lame, like 'It's a very erotic idea, but we would all have to face each other in the morning. Could be a bit difficult in the cold light of day' and we left it at that, with Donna still buzzing away upstairs. I spent half the rest of the night, kicking myself for turning down what might have been a bloody good opportunity to have some really raunchy fun, and spent most of the next day feeling quite moody.
That night, Laura was back at work on a night shift, so we had an early meal in the evening. The three of us were just chatting about various things while we ate, when Donna, in her inimitable way, out of the blue came out with: 'I much prefer anal sex to vaginal.' This was typical of Donna... just say it like it is. We were both taken aback, and a bit lost for words, but I gulped and managed a rather lame 'Why's that?', secretly hoping to get a bit more detail. She then went on to explain that 'It feels so much more intense; there's much more feeling!' Pete had apparently 'only got a little one' and 'it didn't really fill her up or satisfy her'.
Laura and I had only tried anal on a couple of occasions - both entirely at my insistence. I really wanted to fuck her cute little arse, but even after a few drinks, she only ever let me pop the head in for a few moments, before complaining that it hurt, and telling me to take it out. So it definitely wasn't on her sex menu.
Slightly embarrassed, we managed to change the subject by clearing the plates and taking things out to the kitchen. Laura busied herself with getting ready for work and Donna went to settle the kids down for the night. I washed up and tidied the kitchen, by which time, Laura was getting her coat on, ready to go out.
With the prospect of another pretty boring evening, watching dull TV, I gave her the usual kiss and 'have a good night' routine, at which point, she leaned close and whispered in my ear, 'You can fuck Donna if you like.' It was one of those rare occasions when I was totally lost for words, wondering if I'd heard right. I was still standing there rigidly dumbfounded when her car went off down the road.
My mind was scrambled as I tried to reconcile this in my head... Did she actually say what I thought she'd said? Was I hearing things? Did she mean it? Was it just a 'test', with Donna primed to report back about any advances on my part? Apart from anything else, would Donna actually be up for it? I didn't know what to think, but I could feel my pulse racing.
I was still caught in this dilemma when Donna called out to me and said, 'Is it ok if I have a bath?'
I snapped out of my trance and replied, 'Yes, of course, there's plenty of hot water, go ahead.'
Now, sometime ago I had noticed, when I was sorting some stuff in the loft, that there was a gap in the bathroom ceiling, just where the coving met the ceiling. It was almost invisible from below, but from a vantage point in the loft, I had discovered that it was possible to see the whole of the bath and the toilet area - something that came in very useful when we had a beautiful 19-year old German au pair staying - but sorry, that's another story.
While the water was running, I crept upstairs and positioned myself in the loft, then kept very still. Before long, I saw Donna enter the bathroom and close the sliding door. She stripped off, then sat on the toilet, obviously having a pee before her bath. I had only ever seen her boobs once before, when she was breast-feeding; now was my chance to have a proper look.
It did occur to me, that my perving behaviour was probably unnecessary, because if I'd asked her straight out, she would probably have just stripped off for me. But peeking through the crack in the ceiling gave an added voyeuristic thrill - the stolen glimpse of someone naked, knowing they can't see you looking at them.
Her tits were still quite large with pronounced deep brown areolae round her rubbery nipples. She bent over the bath, to stir the water and check the temperature and in the process, gave me a lovely view of the curve of her bottom. As she lowered herself into the bath, I could see the triangle of curly pubic hair round her pussy. I watched with interest and got quite aroused as she washed her body all over. She seemed to be paying particular attention to her breasts and pussy, and I was hoping she might continue on to masturbating properly and give me a proper show.
But she then sat up and started to wash her hair. I reckoned I'd seen the best part, so decided to creep out of the loft while the coast was clear. Heading to the bedroom, I undressed and changed into my dressing gown, to be comfortable for the evening. Then I went back to the lounge, when suddenly there was a cry from the bathroom: 'Ow ow ow! Help!'
