I had an amazing marriage that had stood the test of time and my wife had indulged my fantasy to introduce an old boyfriend of hers to our marital bed. The sex could not have been better, but crudely she was struck down with some serious medical problems and had to have major reconstructive surgery. I am a patient man and her recovery was my only concern. Unfortunately not only was sex no longer physically possible, she didn't get the urge and it frustrated her to pay me any sexual attention. So we didn't do anything. I love her and while sex had been great I was lucky to still have her. She had a obviously discussed this with her Mum. Brenda was old when she had my wife so the age gap was huge. We always had a great relationship. She was a buxom lady who was attractive and always smelt great. I first had sexual feelings towards her whilst doing some decorating at her flat. She was staying at our house and I had to move all her stuff out of her bedroom. Under the bed were drawers that contained silky items of clothing I had never seen her wear or appear in her washing line. I suppose as the generation that never liked to through anything away she had retained old corsets, stockings, suspenders slips etc. I was shocked at my own reaction to them and they all smelt so fresh and of her. There was always a lot of banter between us and she flirted openly calling me her boyfriend to her friends. Having thought of her now in a new light I noticed how great her tits looked in her silky full length night dress that had Lacey cups and thin straps. It wasn't designed to be sexy but she filled it amazingly and I never minded when she brushed past me in the small kitchen or hallway. She had returned home after the decorating and was very grateful. She had moved back in and I had put some pictures up late one night and by the time I was finished working she was ready for bed. As I walked up the hallway she called to me from her bedroom. "Are you off only I have got into bed already" I popped my head around the door and she was under the covers. I bent and kissed her on the cheek. Now she had previously said to me "Are you going to get in for a cuddle" but I hadn't taken any notice. I was now thinking of her in a new light. When she asked me this time I knelt and kissed her again. This time on the mouth, gently. She took it in her stride and smiled. She pulled back the covers and I hesitated and asked if she was sure. I kissed her again. This time more lingering and my tongue moved briefly into her mouth. I stood, stripped down to my boxer shorts and slipped in beside her, facing her and we kissed again. First we cuddled and I felt the silky material that clad her full body. We kissed passionately and I managed to move the nightdress up around her waist to discover she didn't wear knickers in bed. I felt her soft large bottom and then moved to the front to feel her pussy. She was completely hairless and the skin was so amazingly soft and warm. She told me she knew I wasn't able to be taken care of at home and she would be happy to provide company for sex. She moved her hand towards my cock which was obvious in our embrace. I removed my boxers and lay on my back and she worked it in her hand. She wasn't particularly practised in the art of wanking but the experience was just mind blowing. I massaged her gorgeous tits through the Lacey material and then freed them one by one. Bringing them out into full view and sucked on her nipples in turn. This distracted her and I could tell she was very turned on by it. I put my hand between her legs again and her mouth opened and gave a few little groans as I slipped a finger inside to find her clit. It was slow, sensuous and beautiful and I bought my Mother in Law to a climax. I knelt up and wanked my cock furiously over her lovely tits. I shot a jet of spunk right between the two and then rubbed the head over each nipple in turn. When I was empty I rubbed the cum all over her wonderful top half and we kissed some more. We cuddled until we almost both fell asleep but I dressed to leave and she just rolled over to go to sleep. She said it was to be our secret but she wanted to make sure I was a happy boy and continued looking after her Daughter. I was very happy with the turn of events and this was the beginning of a wonderful relationship that progressed and lasted for years.
