STEPHANIE<br/><br/>I took the stapler from Nat and knelt in front of Kevin. Up close he was quite a nice size... if you liked that sort of thing. It had been so long since I'd been to bed with a man that I'd almost forgotten what one felt like. Natalie and our shared strap-on was more than enough for me, and quite often we didn't use that. I liked the freedom of not having to work towards the same conclusion every time. That was what was predictable about sleeping with men; a bit of that, a bit of this; you suck me, I lick you, grab your tits and then<em>hup!</em>up we go. Mounted. Like a bloody horse. With a woman the cycle was endless, an endless lovely swirl and ride of anything we liked. If fingers were my mood for the day we could have an entire session of fingers. Kissing wetly and urgently for an hour? Nat was so good at that. Your partner being delighted to make you come three... four... six times and you give her the same? Yes, some days. No structure. There was no structure, just our imagination and the finite boundary of our exhaustion. That was what I loved about sex with Nat.<br/><br/>I put my hand on Kevin's warm firm-soft flesh. He was hard so clearly enjoying this, the naughty boy. All that bullshit he'd given us about the writing piece when all he'd done is crave a bit of fem-dom. Silly boy. A foot from the stapler I made a slip-loop of string, doubled over and looped it around his balls, dragging it tight so it squeezed the part of him, the 'stalk' or 'root' of his balls where they hung down from his body. His hair was an annoyance, it had to go. It would get caught in the string and pulled too so it would hurt him a little as well.<br/><br/>After I'd looped more string around the 'root' until it looked nicely bound and his balls were a slight red colour I tucked the loose end of the string under the bindings at the back and then pulled it through. His fleshy stalk was a little in the way so I kept it still by the simple expedient of popping it in my mouth. May as well use my tongue while it was there... I didn't give him a blow job as such, but idly licked and washed at his head with my tongue as I worked to feed the string through under the loop and then I hauled it forwards between his balls, dividing them tightly and fed the string up under the horizontal bindings at the front. It was damn fiddly and time consuming. Some specially made cock and ball weights and rings would be much quicker and look a lot more elegant. I fed the divider strap (which is what the central loops of string had turned into once I fed the length back and forth five or six times under and over the ball bindings) back down to the stapler and tied off with a last good knot, nice and tight so it would be impossible to get undone. We'd probably have to snip it with scissors to untie him. Giving his knob a last nice licky-sucky I knelt back, smiling up at him.<br/><br/><strong>"There you go. And you got a free cock sucking while I was down there. Don't you ever go thinking I'm not nice to you."</strong>I stood up elegantly and put a finger to my lips, carefully and tidily wiping away a little bit of spit. I reached down with my hands and grabbing hold of his stalk firmly I tugged his foreskin back hard so his shiny swollen bell-end was all bare and naughtily exposed. I tugged it back again covering him, then grinning tugged it down once more. I left it like that.<br/><br/><strong>"Punishment if you're late back my lad. But if you're early..."</strong>I swirled my fingers around his knob, caressing, teasing...<strong>"You get a reward. Pain or pleasure. Your choice."</strong>I kissed my fingers and placed them on his mouth and gave him a succulent, saucy wink.<br/><br/>I walked to the door and opened it, glancing out. The corridor was deserted. I listened carefully. I knew this school well, knew every brick and tile of its fabric, every pane of glass, every panel of skirting, knew the noises it made in the evenings when it clicked and ticked and settled as the heat of the summer day radiated out of it, knew the faint sound of students calls from the sports field, knew the way that distant footfalls echoed down its corridors. I knew every hint of someone moving somewhere in it's structure...<br/><br/>Silence...<br/><br/>The coast was clear. Students gone home, cleaners not yet arrived, though sometimes the two did overlap. If there was a game on the cleaners came early so they could get home to enjoy a beer and some nachos in front of the TV. Who knew? They might be here already, just getting their overalls on in the utility building out back. Kevin might be dead already, he just didn't know it yet.<br/><br/>I took his arm and firmly pushed him out the door.<strong>"You know my classroom. Get going. Be back in five minutes for pleasure, six for pain."</strong>I shut the door and almost screaming with sexual need fell into Nat's arms for a hot kiss, sucking on her soft mouth like a hoover and grabbing at her chest like I was a baby who needed her feed.<br/><br/><strong>"God this was an awesome idea of yours darling. I'm wet through it's turning me on so much."</strong><br/><br/>
