This is rather long, and there isn’t much sex in this first part. It is however, totally true, and I think a proper introduction is needed to properly understand the scale of the transformation that my wife has undergone in the last couple of years. We are both approaching 50, but hopefully look younger. Unlike most posts on here, Sue hasn’t got huge firm boobs or long legs, but her body is still trim and certainly doesn’t show her age. When I met my wife Sue, she was in her mid-twenties, slim, brown haired and a virgin. Not only was she a virgin, but she hadn’t even been touched, and had never had an orgasm – all the result of a strict Catholic upbringing. She had a long history of short lived relationships, that all ended abruptly after a few weeks, when it became clear that sex wasn’t on the agenda. Sue told me years later, that when we started dating, she immediately decided that I was “the one”. Even then, it was nearly 2 months before I got her naked and she had her first orgasm, and a further 3 months before we made love (she wouldn’t dream of using the word “Fuck” in those days). The first blow job was still nearly a year away. Despite Sue’s late start, and background, we did have a few years of good, conventional sex. Sue would occasionally shave her pussy, and on holiday I did get the odd naughty photo. Probably quite a typical situation. When the kids came along, sex became less frequent, and even less adventurous. When I got the chance, I would play with Sue’s pussy to give her a clit orgasm – which would typically take around an hour, After she had cum, sex would be good – but this was only happen 2 or 3 times a month. On other occasions, Sue would “fob me off” with a quick blow job. We both knew this was the case, but I didn’t say anything as she would have stopped that as well. Everything else was good in our lives, Sue didn’t miss frequent sex – partly due to her sex-free upbringing, but also because she didn’t feel sexy. This was despite me frequently and truthfully telling her she was. Sue has always (unknowingly) given off an air of sexuality – hence the earlier stream of short-term boyfriends. If anything, this was increasing as she matured, and was very frustrating for me. Fast forward to our late 40s, and the kids were about to fly the nest. We finally had more time as a couple – rather than parents – and we started to communicate more. I shared my frustrations, Sue shared hers, and gradually our sex life started to improve. Still very conventional and not as frequent as I would like, but much improved and again, probably a very typical situation. One Monday, Sue had a day off work. This had made her relaxed the previous evening and so unusually we had made love the previous night before sleeping. This meant that Sue had slept naked – also not typical. When my alarm went off, I saw Sue facing away from me and I jokingly gave her bum a couple of gentle slaps. I expected her to turn over and push me away, but instead she turned on her front making it easier for me to continue. I did so for a minute or so before getting-up and hurrying off to work. That evening when I returned, Sue was a changed woman. She dragged me upstairs to the bedroom, telling me to strip, whilst quickly removing her own clothing. She pushed me on my back and climbed on top, my dick sliding straight into her soaking wet pussy. She rode me frantically and came just before I did – her first ever orgasm without her clit being worked on. As we lay recovering Sue told me that she had been turned on all day and had cum three times whilst playing with her own clit. The light spanking had turned her on like never before, and she wanted more – much more. This was quite a shock to both of us, and we spent most of the evening discussing how we felt about this. I wasn’t sure that I could give her the hard spanking she was asking for, and I was also concerned that if it didn’t have the effect she wanted, she would blame me for hurting her. We agreed to sleep on it, and that if Sue really wanted to have a hard spanking that she should be “dressed appropriately” when I returned from work the next evening. It was difficult to concentrate at work the next day – I thought Sue would reconsider in the cold light of day, but I was hoping that the new sexy Sue would remain. I also wondered, what she would consider as appropriate dress – she had always resisted my attempts to get her to dress sexily, and I had insisted on the dressing up element to see how serious she was. Around 4pm,I got a test from Sue saying that she had finished work early and was going shopping – I wasn’t to go home before 6pm, but to not be too long after. Any hope of concentrating, on my work was gone, as my imagination went wild wondering what Sue was going to wear, as her text left little doubt that she intended to go ahead. On the way home, I told myself not to get too excited as Sue would probably have come to her senses, and we’d be back to normal. I arrived home about 10 past 6 and the first thing I noticed was that the lounge curtains were closed, despite it being broad daylight. I went into the lounge and couldn’t believe my eyes: Sue’s shoulder length hair had been curled and gelled, she had heavily made up her eyes, and wore bright red lipstick, She was wearing a red see-thru blouse, with most of the buttons undone and clearly no bra underneath. Her black mini-skirt hardly covered her bum, and as she turned she lent forward so I could see she was wearing a small g-string, and as no hairs were escaping, I suspected (correctly as it turned out) that she had shaved. Her black hold-up stockings finished inches below her skirt, and she wore red high heel shoes. She looked like a total slut – and I loved it. Sue then asked if I was going to give her a good spanking for wearing such an outfit and being so naughty frigging herself off again. I said no I wouldn’t, but I would give her a really good spanking for not doing it years ago. To be continued….
