It seems the revelation about my Mother In Law has tickled a few folks, and I have been asked for more. Its amazing how many messages I have had from readers (most but not all male) telling me how they have lusted after their MIL's and one or two who have done something about it. Hopefully some of those folks will write about their experiences but in the meantime there was one very memorable occasion that I wanted to tell you about. After that first amazing day with the MIL at her flat I was round there a least once a week if time and work allowed. Jobs that should have taken a couple of hours took all day because we either stopped work when neither of us could resist the urge to fuck any longer, or left the work for later and just went straight to sex, or even just didn't bother to do any DIY and just fooled around! At weekends my wife would come with me to help out her mum with decorating and the like. Obviously there was no time to do anything but the MIL still made sure she teased me, giving me a wink or a flash of arse or boob when the wife was not looking. On one occasion though they found that they had the wrong paint and, as my wife had paid for it on her card, she volunteered to go and exchange it. The second I heard the car pull off the drive the MIL pulled me into the living room where in seconds she shoved her tongue in my mouth whilst dropping my shorts, pulled her panties off, lifted her dress and bent over the back of the sofa. I did not need inviting as I my cock was hard and throbbing with excitement and, as I eased inside her, found that she was wet and ready to be fucked. She was enjoying the urgency and excitement as well, gasping and begging for it. It could only have been a few minutes before I exploded in her, making us both cry out. I was panting hard with exertion and trembling with the adrenalin rush as I pulled out of her. In response to this sudden void in her pussy she groaned and stood to give me kiss. She broke the kiss and, with a sexy smirk, started to kneel, intending to clean me up and knowing her, see if she could get me hard again. As I looked up though I saw our car about to pull into the drive. My wife had turned around when she realised she had forgotten the glasses she needed to read the labels! I had to dive into the loo to tidy up whilst the MIL simply kicked her knickers under the sofa, dropped her dress and carried on! That evening I got a few texts saying how exciting it had been taking such a risk and especially almost getting caught. I think this set the seed for the incident I want to tell you about. We carried on for a couple of months, but then my wife took redundancy. Now she invariably came with me so not only could nothing happen but also the jobs got done quicker, taking away my excuse for going over at all. The MIL and I still snatched the odd opportunity though and even the next summer were still as horny as ever for each other. The wife has a large extended family who all live in each others pockets, so get togethers are frequent. The MIL is the oldest of 5 brothers and 3 sisters, so add in partners, children and grandchildren these gatherings can get big. Her youngest sister had married well and had a lovely converted farmhouse with a big garden, lots of outbuildings and even a walled veg garden. We were there for a BBQ birthday celebration for the MIL and her sister (their birthdays are 1 day apart) along with the whole clan. During the day the sun shone, the drink flowed and everyone had a great time. Although the party was up at the house, there were other little nooks with seating all over the place. At one point I had wandered off and found myself at a table at the far end of the garden under a shady tree. Up at the house games were underway and the wife was off somewhere playing lawn darts or bowls. Walking towards me though was the MIL. I had said hello earlier when we arrived, but this was the first time I had been able to check her out properly, and she looked sensational. Her natural beauty was enhanced with make up and her blonde hair was loose at shoulder length. She was wearing a loose floaty floral dress that was just fitted enough to emphasise her slim waist. Also apparent was the fact that she was not wearing a bra. She had magnificently perky boobs for a woman of her age so could still get away going without, but that just meant that, under such a thin dress her nipples were obvious and more importantly standing proudly erect. I thought this was a pretty racy look for a family gathering, but then again she looked so sexy that I could not help but be turned on. She had a couple of glasses of something sparkly and handed me one as she sat down. We clinked glasses and I wished her a happy birthday. It was obviously not her first because she was in silly, flirty mode “I don’t think you will still want me will you, now that I’m so old and decrepit” she asked, doing a pouty sad face. “Don’t give me that rubbish” I told her “you are fitter and healthier than most of the youngsters here, and you look more beautiful than ever.” “Zo you still desire me, do you?” She said in a Marlene Dietrich voice, “how much, I vunder...”. I just smiled back at her and directed her attention to the bulge which had grown my shorts. “Oh...” she said and just lifted the hem of her dress and spread her legs slightly to reveal that she was not wearing anything. Thank god there was no one nearby or looking down the garden to us. “You appear to have lost your panties” I pointed out helpfully. “Oh, no” she replied in mock horror “you had better come and help me find them.” With that we stood and, drinks in hand, she led the way through the arch to the walled garden. As soon as we were out of sight of the house I grabbed her and kissed her. She responded and for a moment our bodies were mashed against each other. My hands were on her delicious arse as she grabbed my head in both hands, our tongues frantically twisting together. She broke off and pushed me away, saying breathlessly “Not here, this way” and pulled me towards a shed in the far corner. I thought that we were going in there but instead we went behind it, where there was another gate hidden away. Through this and we were in a tiny triangle of ground with walls on two side and a large dense hedge on the longest side. The ground underfoot was soft and spongy from material that had fallen over years, but the most obvious feature was the large tartan blanket spread out on the floor. The MIL was behind me as I took all this in, but when I heard the rustle of fabric I turned to find her stark naked. I let out a groan and she came over to my arms. She was soft and warm and smelt of perfume and fresh grass. Her mouth was on mine and her tongue in my mouth as I squeezed her naked body against mine and groaned loudly in pleasure. She broke off the kiss and put a finger to my lips, nodding her head towards the hedge. I didn’t understand at first, but then heard voices and laughter, close enough to hear most of what was being said. I realised that we were on the other side of the hedge next to the main patio and dining area where most of the guests were drinking and chatting. We had to be less than 10 feet away from most of her family! As I was taking all this in the MIL was grinning like the Cheshire Cat and undoing my shorts. “We are going to have to be very quiet” she whispered as she knelt down to pull my shorts and underwear to my ankles. As my rock hard tool sprang into view she quickly pulled my shoes off and threw them and my shorts away. In the meantime I had taken my shirt off and was as naked as her. She looked up at me with her big grin, then stuck her tongue out and ran it up the inside of my thigh to my balls, where she knew I loved being licked and sucked. As she pulled one of my balls into her mouth I let out a yelp, then tried to stifle another with my hand as she sucked and pulled on the other one. She motioned for me to lie down and as soon I was on my back she got me to lift my arse up and open my legs wider, so that she could get her head in to lick my perineum. She knew that this drives me wild, and as her tongue danced over my skin I had to grit my teeth and try not to make any noise. She was giggling as she finally stopped and pulled me in for a kiss. As her hand grasped the shaft of my cock and pulled the foreskin back, my fingers reached for her trimmed pussy, finding it as wet as I had ever known it. Now it was her turn to moan the loudest as I stroked her, pushing my middle finger along her slit as my thumb brushed her clit. I started to build up a rhythm and in response she was thrusting her hips in sync, whilst also wanking me. She broke off from our kissing and, now panting with excitement, pushed me onto my back and squatted over me in a 69. As she lowered her delicious cunt onto my face my head filled with the musky aroma of her sex, and as she ground her hips she smeared her juices over my nose, cheeks and mouth. I had to grab hold of her to stop her using my face as a sex toy, and allow me to use my lips and tongue to harvest her sweet juices and push into her. As my tongue opened and entered her pussy she gasped and let out a low moan. I think this reminded her of the people in in earshot and, to stifle the noise, she filled her mouth with my throbbing dick. There was no gentle teasing for either of, as we frantically sucked and licked and bit. Both of us are quite vocal during sex so it was incredibly difficult to restrain ourselves, but that only added to the excitement, especially because we could hear the chatter and occasional loud laughter from only feet away. Even though I didn’t want the 69 to stop, at the same time I was longing to get my cock inside her. As this was going through my head though I felt a tremble run through her body and her pussy tighten around my tongue. She stopped sucking my prick but kept it in her mouth, which helped stifle the long, low moan of her orgasm. This seemed to last whole seconds, but as it passed and she relaxed I was rewarded with a gush of her juices into my mouth, which had never happened before. This was her cue to climb off me and assume the position on all fours. I got behind her and pushed my engorged tool all the way in, and the shock of such a sudden deep penetration made her whole body spasm. This time she could not help but let out a loud cry which had to have been audible. Frankly though that only excited us both more, and she looked round to me and in a whispered hiss ordered me to fuck her hard. I started ramming my cock into her more viciously that ever before, but this animalistic act just made her more excited and carried away. With every thrust she was hissing “fuck me, fuck me” and this only got me more excited too, until her body was being hit so hard I had to use my hands on her hips to stop her collapsing. We could not carry on like this for long and soon enough I felt the wonderful release as I shot my load into her. As I pumped in another spurt and then a third I pushed and held my dick as deep as I could inside her beautiful cunt whilst holding my breath to try and stop any noise. When I was spent I eased my cock out of her and flopped back on the blanket panting hard. She was still on a sexual high though, and quickly dropped down next to me to take my now semi hard cum-and-pussy-juice coated cock in her mouth for a hard sucking clean, whilst she opened her legs and furiously rubbed her clit. My cum was leaking out of her but this just provided her with ready access to some lube , and in a minute she had another orgasm, again only partially stifling her moans with my prick. Finally satiated she flopped onto the blanket alongside me to share a hot, breathy sex flavoured kiss. As we came down from our high and thought more rationally we realised we had been hidden away in there for at least 20 mins and someone might have noticed we were missing. Reluctantly we got up and quickly dressed, with the MIL retrieving her bra and panties from under the blanket where she had hidden them! After a final kiss and a check that we both looked presentable we went back through the hidden gate. As we came round the corner of the walled garden we ran straight into the MIL’s youngest sister coming the other way. We said we had just been for a look around, and although she was nodding in agreement also gave what I thought was a slightly knowing look and a little upturn of a secret smile. Nothing more was said though and the rest of the day passed pleasantly. As was usual that night we exchanged texts. She was still on a high, telling me that the recklessness and danger had turned her on so much that those had been the most intense orgasms of her life. She also revealed that she had stayed over at her sisters for the weekend and, as she knew about the secret garden, had planned it all out in advance! We had started something that she would want to repeat, and in situations where we were even more likely to be caught.
