I remember hearing my parents in the bedroom next to mine growing up in a sleepy little South Derbyshire village. In the dead of night my mums moans reverberating through the walls as her and my dad used to make me wonder what they were up to in there - my mum occasionally moaning in the dark.
"No, not there...oooh, don't stop!"
Then her increasing panting and moaning before she'd very obviously cum, followed by my dad's growl as he emptied his load inside her. Then all would go quiet and after a while I would fall asleep.
Fast forward 20 years, and my dad was gone - remarried to a woman who must have been great in the sack, because to me she was as ugly as sin - nothing like my mum who at 5' 2" and weighing in at about 140lbs, with a fabulous arse that my friends used to tell me they could 'munch on all day' and breasts that I guess are around 36D. She never remarried. Mum took care of herself so I really didn't see why Dad decided to run off with someone else - the grass is always greener I guess!
Mum married & had me at 16, so when I was 30, she was 46 - not a massive age gap really, so we'd always got on. I got married at 21, and divorced ten years later after my ex-wife ran off with a much older, richer guy. So for a little while I moved home, and this is where the fun began..
It was mid summer, and in England, summers are not usually that warm, but this one seemed hotter than we'd previously had. Mum was working in the garden in her shorts, and I'd been working in the upstairs study that overlooked the back garden. It seemed that every time I looked out of the window, that fantastic arse was sticking up in the air, as she leaned over to tend the flower beds. As the material was stretched over her backside, I swear that I could see the material stretch between her pussy lips, creating a valley that I could just slide into, given half the chance! I can't deny that the sight of mum's arse and fabulous breasts made me quite hard, which in turn made me quite ashamed, that I could be fantasising about fucking my own mum.
Summer continued, and my new incestuous thoughts about my mum did too - I thought about pulling her shorts down and sliding my cock inside her, or my tongue over her pussy, or joining her in the shower. I knew it was wrong, but I couldn't help myself.
I guess my attitude towards my mum changed, and she noticed too - I bought flowers, and took us out for nice meals, and gently flirted with her. In turn, she started to not act like a mum, and our nights out became almost dates - although neither of us said it. Our goodnight kisses became a kiss & a hug, with her pushing her breasts against me as we pulled towards each other, and my semi-hard cock occasionally being felt against her stomach.
One Friday evening, we went out for a meal and some drinks, and both of us probably drank more than we do usually. We chatted away, and got onto relationships, and I was talking about my ex and some of the hurtful things she'd said in our breakup. I'd asked foolishly if her new guy was bigger than me, and she'd replied that he was bigger, and better than me in bed. Mum was really angry about that, but went on to tell me that my Dad was the only guy she'd ever slept with, and that she'd always enjoyed it, and missed it since he'd gone. She said that Dad always wanted to go 'that little bit further' and because it was only small steps, she always felt comfortable.
As we'd both had a few drinks, I decided to press her a bit more, and asked her what kind of things he led her to do?! She was a little bit embarrassed, but explained that she'd tried anal, and enjoyed it, and that Dad had inserted a large vibrator in her pussy at the same time, which she said made her feel really full but really turned on. How she'd had sex outside in a semi-public place, on the bonnet of Dad's car, and how he'd once finger-fucked her on a crowded train. She told me that Dad wanted to try a threesome, with another woman, but she refused to do that. Again, I was sitting in the bar with my cock straining at the zip of my trousers! She asked me how adventurous I'd been in my sexual travels, and I told her how over the years I'd been with a few girls, not a huge amount, but enough to find out what I liked, and what I didn't like. She asked me what was my favourite thing to do, and I told her how I loved to fuck doggy style, and how I loved to go down on a woman.
Mum's face was starting to go scarlet as we discussed this, and she admitted that she'd loved both of those too. Conversation moved on, and we finished our drinks and wandered home, my mum putting her arm through mine as we meandered back.
As it was late when we got back, Mum said she was tired and was going to bed, and came towards me to give me a kiss & a hug goodnight. She wrapped one had behind my neck, and the other behind my back as she pulled me towards her, and instead of kissing my cheek, she kissed my lips with a long peck. She also pressed her breasts against me and pulled my still semi-hard cock against her too by hugging my back. I kissed her back, and put my hands on her back & one on her buttock.
"You've still got a fantastic bum you know Mum - far better than a lot of girls younger than you, and a whole lot tighter!"
"It's been years since someone touched my bum, or anywhere else for that matter. I'd forgotten how nice it feels!"
At that she said goodnight, and went to her room.
I followed to my room shortly after, and lay in my bed thinking about our conversation, and gently stroking my hard cock imagining how amazing sliding my cock into my Mum's pussy would feel. I came pretty quickly and started to doze off to sleep when I started to hear noises from my mum's room. At first I couldn't tell if she was crying but it soon became apparent that she was doing the exact same thing that I'd done. That got me hard all over again, and I stroked my cock as her panting became more pronounced and after a minute or two, her voice in the darkness moaning.
