Alistair and Katie had been sleeping together for a week. They weren't really going out; it was more like friends with benefits. Alistair had been a virgin and Katie had deliberately seduced him, not that he minded, and in the past week he'd had sex more times and more adventurously than most of his friends who'd lost their virginity three or four years previously.
She was being very thorough in her education, showing him exactly how many positions there were to have sex in. After the very gentle, vanilla sex they'd started with, she began to spice things up a little, letting him take her from behind, fuck her standing up, in public places and they'd even tried anal sex – a first for both of them.
It was very strange, she loved to seduce shy, innocent boys and take their virginity, but what she fantasised about was being dominated by a confident, sexual man who knew what she wanted before she did and pushed her boundaries a little, instead of her always being the experienced one in control.
Alistair was shocked when she started whispering her fantasies to him during foreplay, but after the first shock of hearing this sweet looking girl saying such filthy things he was bright enough to realise that, if he listened carefully, he might hear something he could make use of.
As he listened he created vivid mental pictures of the scenes she was describing and found himself growing more and more turned on.
For a girl who was so obviously experienced and who had led him into doing things he could never have imagined he was surprised at how many of her fantasies seemed to involved being coerced or forced in sexual situations then dominated.
She started off quite mildly, she thought, telling him about how she would like to be tied up...
"I'd like to be blindfolded, then have my clothes slowly stripped off my body. When I'm standing there naked I'd like to be pushed back onto a bed and have my wrists cuffed to the bed-stead.
"Once I'm naked and tied up I think it'd be really sexy to just lie there, not knowing what was going on, while a deep, male voice told me exactly what he was going to do to me.
"Next I would feel my legs being pulled apart at the ankle and tied down with rope. I'd be lying there completely exposed now, my pussy visible to anybody who cared to look. What would excite and humiliate me would be that I was wet and aroused and they'd be able to see that too.
"I can feel my pussy clenching and pulsing as I just lie there. Waiting.
"I'd jump as a hand touched my ankle, stroking lightly up the inside with the fingertips. They'd run all the way up to the top of my inner thigh, then skip to my wrist and run down the soft, pale flesh of the inside of my arm.
"My skin would have come up in goosebumps all over from the tingling touches raining down on my body now. Two hands are stroking me now, lips are kissing and licking and I'm driven so wild by it that I can't even tell where or by what I'm being touched.
"Just when I've been stroked into a kind of erotic trance I am startled out of it by the trace of fingers across my pussy.
"Quickly, before I've even registered that touch properly, fingers are sliding inside me, but they don't fill me enough. I'm hungry to be touched – to be fucked.
"I thrust my hips upwards trying to force the fingers further into me. Just as quickly they are pulled out of me, and put in my mouth.
"I suck at the sweet, mildly salt taste of my juices while a large, thick cock slides slowly inside me..."
Alistair stroked her all the time she was telling him this. When she said about the fingers sliding insider her he slid his fingers inside her, finger-fucking her and stroking her clit with his thumb the way she'd shown him.
He could hear the breathless excitement rising in her voice as she spoke to him, nearing orgasm at the motion of his fingers until she stopped talking coherently and gave in to the gasping moans of her climax.
He gasped himself as he felt the strong clutch of her pussy around his fingers, but he kept stroking until she told him to stop.
With each fantasy she told him the action became more and more heated. Soon she was not only tied and blindfolded, but gagged and beaten as well, her bottom spanked until the ringing slaps attracted the attention of a handsome stranger who joined in with the session.
Alistair couldn't believe what he was hearing at the time, but afterwards, when he was lying in bed touching himself, he re-ran the mental movies of the things Katie had told him and found himself as excited by them as she had been.
He knew Katie found it a little frustrating having to tell him what to do and how to do it all the time and he liked the idea of being the one in control. Carefully he thought out his plan, going over every detail until he was certain he would be able to carry it out.
He bought handcuffs, a blindfold and a ball-gag online. He was a little worried that the ball-gag was going a bit too far, but the thought of Katie's beautiful pink lips stretched around the little ball made him almost growl with excitement.
He'd looked at porn before and seen such things in action, but he'd never been so excited by them as now when he was imagining himself using them on her. He liked the image of himself as a powerful, dominant man, getting sex when and how he wanted it.
It wasn't an image he was accustomed to. He'd always seen himself as a bookish geek before, but something about being with Katie changed him. He wanted to be the animalistic man she seemed to want and didn't expect him to be.
He knew she had lectures all morning on Friday, so he asked the cleaner if she'd let him into Katie's room. The cleaner, who'd caught them in bed together several times, accepted his story of something left in there and let him in with his bulging rucksack on his back.
Once in he quickly got to work. He tidied the room quickly so he'd be able to get around it easily. He stripped the bed of everything but the bottom sheet and one pillow and put the rest of the linen in a heap on the chair.
On the desk he laid out his instruments: the handcuffs, rope, blindfold and a small, rubber whip he'd bought on impulse that said it was suitable for soft bondage and beginners. He smiled when he looked at it. Thank God for the internet. He was getting braver, but he wasn't sure he'd have been able to buy all this stuff in person.
He waited by the door as the time drew nearer for Katie's return, listening for her keys in the lock. His pulse was racing already, but when he heard her keys in the lock the jolt of adrenaline flooding through his body jerked him into action.
Luckily he'd gone through this moment several times in his head, because otherwise he would have been too flustered to carry his plan out.
He'd drawn the curtains so the room was almost pitch black. As he'd been standing in it for a while his eyes were accustomed to the darkness, but he hoped it was dark enough to blind Katie while he put the gag on.
She came in and he grabbed her, pulling the gag over her mouth and fastening the snaps behind her head as fast as possible.
Now she was unable to make any noise he grabbed her wrists and quickly cuffed them behind her back so she was unable to struggle either. He blindfolded her now and, with relief, took off the silly black balaclava he'd been forced to use so she wouldn't recognise him while he carried out this bit.
She stood in the middle of the room, blindfolded, cuffed and gagged, her head drooping down as she tried desperately to free her hands. Alistair grinned. He liked seeing her like this and he loved being the one in charge.
He'd thought this through so carefully that he even changed his deodorant and cologne so she wouldn't recognise his scent. He wanted her to think this was real for as long as possible. He wanted her to struggle and have to force her to his will, not lie there and comply because she knew it was him.
He stepped forward and stroked her hair now. She jerked her head upwards, moving it from side to side as if that would help her see who was touching her. Now he had her attention he quickly unbuckled her jeans and pushed them down.
Hobbled by the jeans round her ankles she was entirely motionless now, scared to move in case she fell over. He unzipped her sweater, then unbuttoned her shirt and undid her bra. What to do now? He hadn't known what she'd be wearing and hadn't been able to plan properly for this.
First things first, he thought, and pulled down her knickers. She was shivering now; not with cold, the room was warm, but with fear and humiliation and, yes, excitement.
The situation was far scarier than she'd thought it would be and she couldn't quite believe that this was real, but it must be – whoever this guy was didn't even smell like Alistair and he was the only person who could have planned this without actually being any threat to her.
She clenched her buttocks together to try and protect herself, but she knew it was utterly pointless as he pushed her back onto the bed and yanked her trainers off, followed by her socks, jeans and underwear.
She tried to kick out then, but he was too quick and was already tying a rope about her ankles. Jesus. He'd come completely prepared – God only knows what else he was prepared for.
He turned her over now, kneeling on the small of her back as he undid the one bracelet of the cuffs. Quickly, before she could hit out too much, he pulled off her shirt and sweater and pushed the bra straps down her arms.
