I have been married to Charlotte (Charlie) for 10 years now, we have 2 young children and a pretty good sex life. Over the last couple of years we have started to explore our fantasies a bit further. A bit about Charlie - she is 30 years old, long strawberry blonde hair, size 10 with 34B breasts,and an arse to die for. Charlie has always been a bit submissive when it comes to sex and it has always relied on me to push our boundaries forward. Since the children Charlie's sex drive seems to have increased significantly and she has been much keener to tell me what turns her on. There are several regular themes that keep coming up: 1)she enjoys being told what to do, likes me to treat her like a slut and be graphic in the language I use in the bedroom. 2)gets really turned on at the thought of 2 dominant males forcing her to be their plaything (spit roast, DP, restraint). 3)gets excited by stories of BDSM. Whilst I don't think she would like much pain, she always tells me to pinch and squeeze her nipples hard when she comes and loves her arse being explored. For the last few months I have been suggesting ruder and more daring games for us to play. We have been out for a night when she has worn no underware and part way through the evening i have sent her to the toilets to lube her arse and cunt and to play with herself. She has then had to spend the rest of the evening looking relatively classy on the outside but filthy underneath. We are now using anal toys far more in our sex life and Charlie loves me to tell her how naughty and dirty she is as we use them. To try and keep Charlie hot I have borrowed some new porno movies form a friend and we have been working our way through these over the last couple of weeks. I have moved our video into the bedroom so we can watch these when we have sex. Charlie has always been quite receptive to porn and this is where a lot of our ideas have come from. Normally when we watch the films I play with Charlie till she comes and then have sex with her. I also really enjoy talking to her about which bits make her horny, although I usually know due to her reaction. She likes me to tell her how naughty she is for watching the films and as we have sex she says things like “I’m like the girl on the screen having to take them all, aren’t I?” Here comes the good bit…………….. This week I have been out every night with various meetings and travelling, and we last had sex on Sunday – both of us being too tired since. Last night Charlie was expecting me home at about 11.30pm and as usual she would probably be in bed, if not sleeping, reading. Well I managed to get home at about 10.15 and was surprised that the downstairs lights were off and the landing light was left on for me to go upstairs. Thinking that Charlie had probably just had an early night I quietly made my way upstairs. As I approached our bedroom I could hear moaning noises that I recognised as being one of the porno movies. I was instantly turned on, but rather than go into the room I listened for a couple of minutes thinking how to play this. To my knowledge Charlie has never watched any films on her own and I have only been aware of her masturbating when in front of me as a horny task. I think Charlie would have been really embarrassed if I had walked right in on her and completely caught her in the act and I thought I could have a bit more fun with her if I didn’t let on I knew. I went to our second bathroom and brushed my teeth quietly, then flushed the toilet, which she would have heard and went straight into the bedroom. Between flushing and entering there can only have been about 3-4 seconds and this allowed her enough time to turn off the TV but not to compose herself. The lights were off when I entered the room but one of the curtains was open so I could see Charlie pretending to be asleep. She pretended to disturb, looked at the clock and said, “You’re back early”, I explained that my meeting was over sooner than expected; she said that she was so tired she decided to have an early night. We chatted a bit; I turned on my sidelight, shut the curtain and took off my clothes. Charlie asked wasn’t I going to use the bathroom for a shower but I said no, I would go straight to bed. She was behaving really sheepishly and as I got under the duvet I could see she just had her black hot-pant style knickers on (these are quite shear and see through, and much sexier than they sound). Because she was lying on her side looking away from me, I also noticed that she had a small lump protruding from the back. I knew exactly what this was – a vibrating butt plug that we haven’t used because I thought Charlie thought it was a bit too big. I found it exceptionally horny that she had been wanking, with her arse stretched by the plug and she was now having too lie there with it in her so as not to let on what she had been up to. I asked if she fancied doing anything as it had been a while but she said she was too tired (bloody cheek), so I read for a while before tuning off the light. I couldn’t go to sleep because I was dying to hear Charlie remove the plug and subtly hide it without disturbing me. After about half an hour, it was now me pretending to be asleep, but rather than sort herself out I could tell she was now wanking. Whilst she didn’t turn the plug on she was obviously pushing it in and out of herself as she wanked. When she had finished she went to the bathroom, and I checked her side of the bed, and under her pillow was her vibrator and a tube of KY (not something we have ever used – we use Vaseline). This morning when Charlie was feeding the children I turned on the video to see what she had been watching. It was a scene were a girl was being held on a bench by 2 guys as she was being fisted by another – the girl in the film also had a dildo up her arse. Now to my dilemma………… The weekend is nearly here and this is when we have our more kinky sex. I will want to play games where she is submissive, but should I let on I know what she did last night and punish her for it? Or should I keep quiet and try to encourage her to tell me about it herself? I would really appreciate some more ideas of things to try out with Charlie, she keeps saying to me as we have sex “you like hurting me don’t you” but other than pinching her nipples and lightly spanking her bum I am completely devoid of the next stage to take this and obviously don’t want to do anything too drastic. I’d appreciate a reply ASAP so that I can use any ideas this weekend.
