I knew that dating an engineering student was a bad idea. Julie was damn hot, sure, but even when I first met her I knew she had a dark side; she seemed to look at everything as if she were enjoying some private joke. That’s not to say she treated me like a joke, but even when she seemed to have her full attention on me, I could tell that wheels were turning in her head, focused on something entirely different. When I outed myself to her as a submissive, her eyes lit up, and while she toyed with me for a few minutes, acting shocked and bewildered, she finished off with a laugh and confessed that she identified as dominant, herself. Our sex life changed dramatically at that point, with me having someone to give myself over to and her having a new toy to play with.
The first thing I learned was that Julie was a total bondage freak. Whenever we did anything intimate, I could be sure I’d be tied up, cuffed, or gagged at some point, if not all at once, it is just a part of the total control of me and control of my orgasm she exercise! She’d lock me in a chastity belt for weeks, teasing me for the duration until my balls ached and I begged for mercy. Then she’d tie me down and ride my cock until I experienced the most powerful orgasms of my life. She seemed to get bored with some of this, though, finding the usual ropes and cuffs to be a bit too bland. This was when she began experimenting with her own ideas, blueprints and all. My science-loving girlfriend/domme soon had me enduring some of her newest toys, such as a series of pulleys and other mechanisms that would leave me suspended, and could be adjusted to change the way in which my body was oriented. Sometimes I’d be floating horizontally, face down, with her tugging roughly on my cock as if milking a cow. Others I’d be in a sitting position with her grinding in my lap, and while she couldn’t have weighed more than 100 pounds, it still put just enough strain on the bondage to make it more agonizing than pleasurable for me.
I thought I’d seen it all until Julie excitedly introduced me to her Valentine’s Day gift, something she referred to as the Boybreaker, an orgasm control machine. It looked similar to a fucking machine, something I’d had the “pleasure” of watching Julie enjoy while I remained strapped to a chair, my hard cock bobbing and leaking. A dildo was attached to a piston, which would thrust forward and back at a remote-controlled pace. However, another arm on the Boybreaker attached to a Fleshlight, a “pocket pussy” toy. I could see where this was going, but I didn’t argue. We’d done pegging before, where she’d fuck me with a strap-on, but I was hesitant about being fucked by a machine rather than my sexy girlfriend. I was soon tied in place, spread eagle on my back, with the intimidating machine between my legs. Humming to herself, Julie lubed up the toys and then fit them into place before starting the machine. The dildo pushed into my ass, and fortunately it wasn’t bigger than the ones we’d used in the past; even better, the Fleshlight was also attached to an arm which would cause it to slide up and down my cock. The anal stimulation coupled with the other toy masturbating my cock was simply too much, and it was only a matter of limits before I could feel my orgasm nearing. I squirmed against the restraints, breathing faster, but then the toy around my cock slid away, leaving my dick twitching.
I looked over at Julie in shock and she simply looked back at me with a grin, “Oh, I forgot to tell you about the little addition I made. There are electrodes lining the toy that can sense when you’re about to cum. When you get close to making a mess, it will pull away for a minute before continuing.” I was speechless, and by the time I started to say something in response, the toy slid back down around my shaft, making me groan in pleasure. By my fourth stifled orgasm I was begging Julie to let me cum. Instead she moved closer, planting a kiss on my lips, “I have to be sure my toy can stand up to prolonged use; a good eight hours should be suitable for testing, I think.” As I tried to imagine if I’d survive eight hours of edging and orgasm denial, I idly wondered whether the “toy” she was talking about was the Boybreaker or me.
