My mother-in-law, Ellen is now in her late fifties but still gives the impression of being a very sexual woman. She has put on some weight around the waist and thighs since I first met her, some ten years ago, but she is tall and carries it well. Ellen is very open with Yvonne, my wife, and has told her that she has had affairs in the past due to the fact that Yvonne's dad has a low libido. She even admitted that she had fucked one of Yvonne's teenage ex-boyfriends soon after they had split up. These admissions stimulated my fantasies and soon after meeting her I was dreaming of fucking her. She did not help the situation by running her hand up and down my thigh quite a few times, one hot summers day, while I was wearing shorts, while commenting on what hairy legs I had. She also seems to end up often sitting cross legged, or worse with her legs splayed wide, on the floor opposite me when wearing very tight leggings, making it difficult for me to avoid staring at her crotch but maybe that was just coincidence?

Yvonne and I were living together, in a flat with no garden so one hot day we decided to go to her mum and dad's to sunbathe in their sheltered back garden. When we arrived we found her mother was about to do the same thing. Yvonne was wearing her swimming costume beneath her clothes and I had some very short flimsy running shorts on so we quickly stripped down to these and went out, put down our towels on the grass beside each other and lay down on our backs with our feet towards the door and the sun. After about five minutes Ellen emerged wearing a skimpy, tight, yellow, floral patterned bikini and walked slowly right past me as I gazed, from behind half shut eyes, at her body and in particular at her crotch. After walking along the side of me she disappeared from my field of view and I heard her lying down somewhere above my head.
I thought no more about it till Yvonne's dad came out and told her one of her favourite films was on TV. Yvonne jumped up and headed inside with her dad. As I had been out a while I decided it was time to turn over. I did so to find Ellen lying on her front, her bare feet towards me, only a yard away from my head. Unfortunately her legs were together but when I put my head on my hands as I lay down again I got a great view of her butt rising at the top of her long smooth thighs and the intriguing dark valley that ran upwards between them. I could feel my dick start to thicken as I thought about massaging those soft mounds, so near and yet so far. I lay there enjoying the view at least, staring quite blatantly as I knew that from the house my eyes could not be seen. Better was to come.
Ellen soon decided to turn over also and I closed my eyes as she started to move lest she see the direction of my gaze. When she had settled I cautiously opened my eyes and was stunned to find her legs were now slightly apart, affording me a view right up between them to her crotch. Here I was with my head no more than five feet away from my mother-in-laws cunt staring straight at it and with only a thin veil of bikini fabric wrapped tightly about it. My cock was now firm and I had to shuffle about to get it to a comfortable position. I was now beginning to worry about what would happen if Yvonne came back out, or worse, if I had to get up as my aroused state would be obvious for all to see. I forced myself to shut my eyes and turned my head to face the other way. After a few minutes my problem receded a bit and I heard some more movement from Ellen's position so I turned back towards her. What had happened however was that she had now pulled her knees up and spread her legs so I now had an unfettered view of her crotch from where her buttocks pressed the ground up to the prominent curving mound of her cunt. My cock sprang to attention as I realised that to give that smooth a profile beneath the sheer bikini bottoms she must be either shaven or very lightly haired. I tried but I could not wrest my gaze away from her. I was lying there in shock.
