Arrived home early and without warning one day, thinking I'd be first in the house – but no, it was obvious from the light under the door that Caroline had beaten me to it. I decided to let myself in quietly and surprise her when, to my surprise and delight I heard a low sound coming from the bedroom as I eased the door open – I knew immediately she was masturbating. Now, she does do this when we're having sex, but coming across her at a private moment was incredibly arousing – I was hard in an instant. I immediately decided to let her carry on, and peered through the half-open door at her as she lay on the bed and played with herself. I'd often wondered what she'd look and sound like on her own – and it was good. She was still clothed and had simply pushed her jeans and knickers down around her knees so she could easily reach her cunt and her bra was pushed up above her breasts and sat tightly over her large, excited tits, the nipples very swollen. I nearly shot off on the spot.
Caroline was talking to herself as she fingered away and using every sex word I'd heard, but in a low, intense way. I could see her wetness on her busy fingers as she stroked and twisted her clit and every now and again she reached down and put one or to fingers into her hole, before drawing the juices up her cunt and smearing them over her clit again.
How long would you wait before you did something? I wanted to carry on watching but could hardly jack off in the hallway and anyway, I had other ideas. I reckoned this was the chance I'd waited for to bring off one of my long-standing fantasies of bringing a little S & M into our sex life, and give us both a great sex session. It wouldn't happen if I let her carry on much longer – she was showing signs of building up. I took a quick decision and snapped the light off in the room, putting her into sudden darkness. She squealed and curled up into a ball, then yelled at me to get out.
This was the difficult bit – to get her to carry on, and I hoped she would be sufficiently turned on to be persuadable. I spoke in a low voice. 'Caroline, you can't stop now; you're too horny. And you look amazing. Put your hand back and start wanking again. I love you, and we're going to have the best sex we've ever hand. Come on, Darling, you know you want to put your hand back on that juicy cunt of yours and frig that clit of yours.
In the dark I could make out her body straightening out and her hand stealing down to her pussy again. As she started to frig herself I carried on speaking in a low voice, building up the language until I was talking filth to my beautiful, sexy girlfriend as she worked her cunt on the bed.
Soon, it was time to move. My own needs had been met so far by watching and listening, but my cock was like an iron bar in my pants and I wanted a share of things. I went past the bed to my chest of drawers, reached into the bottom drawer and extracted a number of items I had recently acquired from the local sex shop. A riding crop, long, thin and whippy – I had tried it on myself and knew it would sting. A black blindfold. A wrist restraint. And, in case she got too noisy, a ball gag.
Over on the bed Caroline was valiantly carrying on her wanking. So far, I hadn't laid a hand on her, but that was about to change. I walked over to the bed and took her hand off her pussy. She was very wet, I noticed and her whole groin area was damp. There was a wonderful smell of excited cunt too.
'I'm going to stop you for a minute, Caroline, I said, ignoring her groan of frustration. 'You knew I'd be home shortly, but you chose to deprive yourself of a perfectly good, stiff prick, and me of my much-needed satisfaction. That makes you a naughty girl, doesn't it?' She moaned agreement while her fingers stole back to her slit and she carried on stroking her clit.
