My mother in law lived near the airport. Tiny house, she was a widow, wide hips, big tummy, big tits, but short. She wore girdle type corsets and I was always a little embarrased by her. I was too embarrased to kiss her cheek when ever we met but shook hands.My wife got hospitalised and the hospital was near the airport. After a week when it was obviously going to be a long haul my wife suggested I stayed at Nans.Upstairs was her bedroom, a thin bathroom and a tiny back bedroom. After a week I had my first wank trying to keep it quiet.At breakfast I thought I saw, it might have been my imagination, she was a bit pink and was not looking at me.That evening I kissed her on the cheek, suprising us both and fled to the bedroom. The night I wanked again, not caring if she heard me, but frightened she would. My orgasm lasted ages. The next morning she really did not look at me. In the evenings when I got back we watched TV in the front room by the fire. I found I was watching her tits more and more. I also found I was going into revieries and getting a stiffie. I started keeping my hand in my pocket and doing a one finger stroke wondering how long I could keep it up. I went too far, and found her frowning at me. She said she was going to bed. She went up and I followed her after I heard her leave the bathroom. She had not closed her bedroom door. I stood on the landing for five minutes in total fright. Then ran into my room and shut the door without using the bathroom. Ten minutes later I heard her door click shut.I was a fool I knew, I could have put my head round the door and appologised. She might have been lying on the bedstark naked, herhole ready and willing. I was too angry to wank.The next evening she brushed against me twice as we passed in the coridoors. Usually one or other would back into a room. We had the TV on but really watched each other in a non eye-contacting way. She went to bed and left the bathroom. I went up.Her door was ajar. I cleaned up and went to her room. I knocked gently and pushed the door. She was in bed. Propped up on pillows her little pink bedside light on. Still in her girdle and breathing fast. She licked her lips. I dropped everything I was going to say, and my dressing gown as well. My penis saluted and she opened the covers. Her pubic hair was white with a few greys (she dyed her hair) I climbed on the bed, and straight between her little fat legs.I went straight into her hole with my cock, Her pussy went on forever with big soft lips, before diving for her tits. She had wide arealoes (?)and fat chewable nipples. Her tits were far bigger and softer than my wildest dreams.I fucked her three times the first night over her whalebones. I whispered 'mummy' into her ears when I came.She kept her corset on for three days before I could persuad her out of it. Her tummy was huge and soft. She liked me slavering over her clitoris later and would make me do so for hours before mummy would let me fuck her. Or she would wank and suck her boy. She told me one time how when she had heard me wanking she had wanked too, but had been embarrassed at the thought I had heard her orgasm. And she took her teeth out. You have not been blown untill you have been blown by a soft mouth full of soft gums. Kissing was good too. Getting my tongue in her gummy mouth was heaven.I called her mummy for the next three years. I would pop over to mow her little lawn, plant some seeds, do some decorating. She died then and was found in the front room with the tv on, a cup of tea beside her. Its good to make someone happy before they die. Finally, My wife was suprised by how much more I was fucking her after her mum died. But then she was beggining to look more like her mum too. And she did not mind me calling her mummy either. (She has a dentist appointment soon too.) Spread the seed..
