This surrealistic incident occurred twenty years ago involving my wifes mother. An incident, the thought of which still had me reaching into my trousers and playing with my erect cock. It was just after I had married Joan and we were living with her parents Dave and Ellen whilst our house was being refurbished. I had awoken one morning with a massive hard- on and thinking the house was empty proceeded to the bathroom for a quick wank, taking with me a very revealing photo of Joan’s mum which I had used on a number of previous occasions. I had taken it the previous year whilst on holiday with the in-laws in Corfu. Joan and her Dad had gone off to explore a local market, leaving myself and Ellen lazing together on the beach. On the spur of the moment whilst cleaning my camera I jokingly said to Ellen, pose, this one’s for Playgirl magazine. She posed, I quickly clicked the camera and thought nothing more about it. It was not until I saw the developed photo that it became apparent just how provocative her pose was. She was leaning forward directly towards the camera wearing a black swimming costume, she had pulled the front down a bit from the waist exposing the top two thirds of her magnificent tits. Those 40GG matronly sized tits were hanging down and the outline of her erect nipples could clearly be seen straining under the tight material. She was obviously feeling sexually aroused as she pouted at the camera, and she looked incredibly sexy for a fifty year old woman. My cock leapt at the sight of that photo when I first saw it and needless to say I never showed it to Joan but kept it hidden in the back of the wardrobe for my own private viewing. And this was one of those private viewings. I leaned the photo on the back of the basin and standing naked with my feet slightly apart proceeded to wank, imagining I was tit fucking my mother-in-law. Suddenly the door opened and there stood Ellen dressed in a pink silk dressing gown, it seems she had decided to take the day off. She stood there mesmerized and I froze, still gripping my erect cock. Neither of us moved as she looked at the photo of herself then at my cock. I could see her mind working overtime, trying to take in the situation. Having recovered enough to move I was about to pick up a towel to cover myself when I noticed her nipples becoming erect under the flimsy material and the fact she had not rushed out of the bathroom made me think she was turned on by me using her photo in this way. God I had never felt hornier in the whole of my life or ever since. Without thinking of the consequences I turned to face her and began slowly pulling my hand back and forth along the length of my cock, not sure of how Ellen would react. She just stood there frozen, watching me wank. Then slowly she let her hands fall to her side allowing the dressing gown to open. There revealed was the most enormous pair of floppy tits I had ever seen. Each one tipped with an equally massive erect pink nipple, the tan lines from her swimming costume were still faintly visible. Still neither of us said anything or dared look at each others faces, both aware that the spell would be broken if we did and the moment lost for ever. Her stomach was slightly sagging with age and her fanny which was clean shaven looked like it had been well used over the years. In spite of this she still looked incredibly sexy. For a full three minutes she just stood there watching me using her naked body as wank material, and then allowing her dressing gown to fall to the floor she proceeded to play with herself. She moistened the index finger of her left hand and using her right hand to part the lips of her vagina began rubbing her clitoris, her legs slightly apart and bent. Her right hand then moved up to her left tit which she cupped and squeezed, all the time rubbing her moist cunt whilst watching me wanking. She held her nipple between her finger and thumb rolling it gently back and forth, and then gripping it harder pulled her massive expanse of tit in all directions. Moving the attention across to her left tit she cupped her hand under and lifted it to her mouth. Her lips enclosed her nipple and sucked. This she continued to do alternating from tit to tit, her eyes never meeting mine. I continued a rhythmic wanking motion, my left hand now fondling my balls. We continued in silence for a good five minutes. Then I heard her groan and saw her body shudder. Aware she had climaxed I gripped my cock harder and wanked faster. Almost immediately I had the most fantastic climax of my life, cum spurted from my cock covering my mother-in-laws stomach and tits. I could not stop it, spurt after spurt covered her naked body. Finally we both finished and momentarily stood frozen allowing a wave of pleasure to travel through our bodies. It was only then that she spoke. Looking me straight in the face all she said was, “Let this be just our little secret”. Picking up a towel she rubbed the cum from her body and left the bathroom. The mutual masturbating session was repeated a week later when we were once again alone in the house. This time it was at the breakfast table, where we both sat in our dressing gowns. Completely out of the blue she said, “Have you been looking at my photo lately.” Somewhat taken aback I blurted out, “No the opportunity hasn’t arisen.” She placed her hand on top of mine and replied, “The opportunity could arise if you want it to.” I instantly felt a stirring in my loins. “I’m not sure Ellen. I don’t think this should be happening. It doesn’t feel right deceiving your daughter like this.” She gripped my hand tighter. “What’s the difference between using a photo and having the real thing? Surely you are having the same thoughts about what you want to do to me whether I’m present or not. Besides if you fell guilty we don’t have to go the whole way, just a little mutual masturbation will suffice. You’ll be doing your mother in law a great service, it’s been a year since I have had sex with Dave. Since he’s been taking those drugs for his heart complaint he has lost all interest in sex. Frankly I’m desperate.” With this she let the dressing gown fall to the floor revealing her mammoth mammeries bulging out of a black Basque. To complete the vision she was wearing black stockings held up by six thick suspenders and a pair of crutchless knickers. “It’s my present to you, I bought it especially. Do you like it? You do want these don’t you?” She pulled her breasts from there bra cups and let them flop down on her chest. Shit that did it for me. I reached across with both hands and cupped them. She moaned with pleasure at my touch. “God that feels good, squeeze my nipples.” This I did. Taking a nipple in each hand I firstly squeezed then lifted her heavy breasts by them. “Squeeze them harder, pull my tits with them. A little pain just heightens the pleasure you know.” I felt her hand part my dressing gown and grip my hard cock. “MMMMMMM, just as I remember it, my daughter is a lucky girl to have such a large friend to play with.” Her hand slowly moved up and down my cock causing a small amount of pre cum to appear. Seeing this she went down on her knees and pursing her lips gently kissed the seamen on the tip of my cock. Then opening mouth wide she engulfed its full length. I felt her mouth tighten its grip as she slowly began drawing her head back and forth along its length. I leaned forward and cupped her hanging tits. The warm flesh spilled out over my hands. Finding her nipples I continued squeezing and pulling them, then weighing them. Ellen withdrew from my cock, and arising said, “You’ve got a real fetish for my tits haven’t you. She jiggled them and leaning forward swung them from side to side. “You like?” “MMMMMMMM very much.” I meekly replied. She picked up her dressing gown and withdrew the belt. “Dave loved this, I’m sure you will.” She proceeded to wrap the belt around the base of her left tit then tie it tight. Forcing it to balloon out and stand proud of her chest. She then placed the belt over her shoulders and likewise tie the other. The result was that now both tits ballooned out standing upright and separate, her nipples now fully aroused were at a ninety degree angle to each other. They were turning blue due to the lack of blood flow to them. “I’ve never known a man not like looking at this.” With that she again leaned forward and shook them from side to side. I had to ask the question. “Men. Do you mean there’s been more than Dave in your past?” “Oh yes we once had a very active sex life back in the seventies. You heard of the swinging sixties, well we did ours a decade later. Dave loved showing me off at sex parties. He’d have me string up my tits like this and offer them to all the men in the room to play with. It turned him on watching them abuse me. Hard to think that when I married him I was a virgin with no idea about sex. It was Dave who taught me. At first I was shocked but in time I began to enjoy it. The trouble is now Dave shows no interest but I am still in need of sexual thrills.” Having asked the question, I was not sure I now wanted to know the answer. But it did explain her sexual confidence. She walked over to me and thrust her tits into my face. “Here they are now yours to abuse.” I sucked and licked her nipples and squeeze her protruding breasts, fascinated by there deformed shape. “I’ve let you play with my tities it’s my turn now.” She blurted. Quickly she moved the plates on the table, clearing a space at the front. Then placing two chairs in front a meter apart she removed her knickers and sat down on the table spreading her legs wide apart, placing a foot on each chair. Using two fingers of each hand she parted the entrance to her vagina. “Get down here and give this some attention. It desperately needs a licking for starters.” This I obliged her by doing. Kneeling in front of her I buried my face in her sweet smelling cunt, flicking her clitoris with my tongue and sucking her juices. I heard loud moaning emitting from deep inside her. “That’s it suck me, lick me, stick your fingers up me. I’ll be your slut mother-in-law, do what you want with me. Use my body you filthy fucker. Who needs a husband when they’ve got a son-in-law such as you.” Hearing such filth made me feel even hornier. I pushed my face hard into her cunt writhing it around smearing it with her juices. Then fingering her. First one finger , then two , then my whole hand slipped up her wet fanny. I went wild thrusting my hand in and out faster and faster. She placed her hands on the table behind her and jerked her pelvis forward so to take even more of my abuse. “That’s it. Fist fuck me, harder, faster. I going to cum.” With this she let out a loud groan and her whole body shuddered as again and again waves of pleasure rippled through her body. Quickly I pulled my hand from her and gripping my prick thrust it up her dripping cunt. It was no use though, I felt nothing. Her gaping dripping wet cunt could produce no friction. Ellen sensed I was having problems as I feverously pounded her body. “Wait I know what will do the trick.” She pushed me away and turning around lent over the table, offering up her ripe full arse. Her hands pulled her cheeks apart exposing a brown puckered arsehole. “Here, this is tighter. Just lubricate it well before you stick that cock up there.” Spitting on my fingers I proceeded to lubricate her mixing in the juices emitting from her swollen cunt. At first I rubbed my finger around the hole to loosen it, then gradually inserted my index finger until it had completely disappeared. Then I added another finger and began slowly finger fucking her arse. I felt her body tense up, then it relaxed as she omitted a low moan, a sign that she was enjoying the sensation. When I was sure she could take me I spread her legs further apart so bringing her in line with my cock. Her hands gripped the table as she braced herself ready for what was to come, her tied tits hung down, now purple with lack of blood. Gripping my cock I gradually eased it into her tight hole. First my cock head disappeared up her then inch by inch my whole cock. Finally I placed my hands on my hips and leaning back admired the view. She was totally impaled on my cock. I waited till I felt her body relax then slowly drew it out, then back in. Sensing that all was well lubricated I gained speed. Feeling her gripping my cock with her muscles made the sensation even better. “Are you OK with this.” I breathlessly blurted out. I’m fine. Haven’t had a cock up there in years, it feels so good.” She began rubbing her fanny as I fucked her. I in turn reached under and gripped her disfigured tits, squeezing them hard. She omitted a whimper and then began grunting loudly with every thrust of my body. Faster and faster I pumped. Like an express train out of control I feverishly fucked her arse, her loud yells turning me on even more. Finally I thrust my cock fully into her arse as it erupted. Again and again I pushed against her buttocks as I pumped seamen into her arse. I let my cock remain in her as Ellen continued to masturbate, eventually cumming a second time. On withdrawing my cock from her arse Ellen turned and wrapped her arms around me, giving me a long linering kiss. It goes without sying we spent the rest of the day in bed having sex, barely stopping with time to have a shower and dress before Joan and Dave returned from work. It was a miracle that we weren’t discovered. Unfortunately Ellen began pushing her attentions on me after that day. She would rub up against me at every opportunity and I often felt her hand squeezing my crutch when she thought no-one was looking. I increasingly worried that Joan would discover us and was relieved when our house was finished a week later so we could move out. It did not surprise me when a year later Joan told me that Ellen had run off with the guy they had in to do the central heating. I must confess I still to this day have private moments with Ellen’s photo.
