My s****r's Bottom

... the wine and were feeling pleasantly d***k. The conversation slowly became more basic and then downright sexual when Janie asked me about masturbating. “Do you do it as much as you used to?” “Janie!” “Well do you?” “Not quite as much as I did when I was a teenager but I don’t have the time any more!” She laughed. “How about you?” I asked. “None of your business!” she teased. “Yes it is. I told you, now you tell me or I’ll…” “You’ll what?” She taunted me. “Take you pants down and smack your bum!” “Oh yes? And does spanking turn you on? I always knew you were kinky!” “It would if it was your bottom.” I said before I could stop myself. “Just you try it little b*****r!” she shot back. So I did. We ended up play fighting like we used to when we were k**s, except wrestling with my fully-developed, semi-naked s****r in a bed was more fun than I could ever have imagined when I was 14. Her body was lithe and smooth, warm and sensual. I managed to turn her over and land one smack on her bottom but as she twisted away from me her bra strap caught in my hand and pulled undone letting her full breasts swing free just as I over-balanced and fell on top of her pressing her face down onto the bed. My cock was semi erect and she must have felt it. Suddenly we stopped. We’d both realized this wasn’t really ‘proper’ and didn’t really know what had happened. “Sorry Janie.

You’re the most sexually exciting person I’ve ever known. There... now I’ve told you.” There was a long silence while she looked at me in shock. My thoughts went from elation at having committed myself to the truth, to deep apprehension of her likely reaction. But Janie just looked at me. Then she said something which surprised me. “Touch me. Touch my back, please.” I gently stroked her back while she pushed herself up on her elbows and let her breasts hang free – sensuous swellings just asking to be kissed. Her panties were pulled tight over her perfect bottom. She looked at me for a long time. There was no anger in her face just some confusion. Her eye’s filled with tears and one or two droplets trickled down her cheek. I knew enough not to say anything but just carried on stroking her back to give her the time to work through what ever it was. “Oh fuck Matty!” She exclaimed. “I don’t know what to say.” “I’m sorry. I shouldn’t have said anything. I’ve upset you.” “No I’m not upset. I just don’t know….” she said, shaking her pretty head. “Look, just tell me what’s bothering you.” “Oh fuck!” she said, more quietly this time. “I can’t!” “Yes you can. ...
