I had been going through a few problems with the missus so her parents asked us down to theirs for a long relaxing weekend away from everyday chores.Karen and I travelled down hardly speaking throughout the journey and even when we got to her parents house things didn't improve much and I ended up making my excuses and went up to bed but not before going into the bathroom and whilst sitting on the toilet I could see an overspilling laundry basket with a pair of panties at the top half hanging off and leant forward to look at them more closely and for some reason put them to my nostrils and smelt a horny sexy smell and on closer inspection could see that they were worn recently by Karens mum Barbara who was a well kept woman of 51 and was always into excercise.As Karen hadn't been up for any bedroom activity for a while I found myself sat on the toilet imaginging Barabara bent over the bath with her legs open inviting me to fuck her from behind as I did my cock sprang up and was rock hard so I placed the panties round my shaft and started to wank myself off and eventually shot my spunk into them and placed them halfway down the laundry basket so she wouldn't know what I had done.The next morning I was up early but not as early as Karen who had gone for a days shopping with her father leaving me at home with Barbara who I saw in the laundry room piling the dirty washing into the machine and I looked at her and wondered if she had come across her spunked in panties but I carried on into the kitchen and poured myself a mug of coffee and shouted to Barbara if she fancied one and she said yes and soon reappeared at the kitchen door in her short red dressing gown which showed off her tanned legs and I could see she liked people looking at them as she sat down and the gown rode up.So what have you got planned for today I asked and she said she was just going to lounge around as the others were out and she told me to make myself at home and do what I wanted and I just wanted to rip her gown open and suck her juicy tits which were hidden and half on show.I made my excuses and told her I would have a quick shower and Barbara told me to use the one downstairs as the one in the bathroom was broken.I stripped off and got into the shower and fixed the water and was soon soaping myself up and down and having a slight wank to try and get my cock down and I thought I heard a creak of a door but carried on washing myself and thought nothing of it and dried myself a bit then put on a towelling robe and rejoined Barbara in the lounge and she was sat there with her legs dangling off the edge of the chair I had to rearrange the robe as my cock was once again hard.Just then Barbara told me she found something strange in the laundry basket and I nervously asked her what and she pulled from her robe pocket the panties I had shot in and I went bright red and apologised and she asked why I had done it.I haven't had sex for 3 wekks I told her and Karen was not interested in fucking anymore and I need to masturbate to get through the days.Then Barabara stood up and let the robe drop to reveal her gorgeous body and walked over to me and dropped to her knees and pulled my tie off and pulled the robe open to reveal my hard cock that was standing to attention and she asked iof she was causing that and I just nodded as she ran her fingers up and down the shaft and licked the helmet which had some precum on the tip and she took my cock into her mouth and was soon bobbing up and down like a pro and I was in heaven and thrusting as my arse left the chair as I fucked her mouth.She was moaning and I couldn't hold on and shot my load into her mouth and was quite surprised she swallowed it and told me she loves the taste of spunk even though John doesn't give her much these days.I removed my glistening cock and turned her round and parted her legs and get a good view of her wet pussy and slid two fingers inside and started to finger fuck her and I felt her push back and tell me to fuck her as she needed fucking.I grabbed her free tits and suqashed the nipples in my spare hand and tugged them calling her a filthy whore and my cock was soon hard again and I lay down on the floor and had her mount my and she was soon bouncing up and down and her tits swung from side to side and she told me to fuck her harder and I did that as she was hungry for more.Then she climbed off and got on all fours so I slammed my prick right into her and she loved the way my balls banged against her arse cheeks and I felt my spunk erupt into her moist hole and held her close so she drained my balls and we then fell into a heap and cuddled each other before she got up to have a shower.We didn't have sex again and I found out she split form her husband and got herself a toyboy half her age but I am just glad I got to fuck a horny older woman.I too divorced Karen and have never been happier.
