I've prepared test subject Luna Dawn in a knee point frog tie at the edge of my bed. Her arms have been massively bound elbow crushed together painfully and her mid-section totally roped up in extreme bondage. Her big tits are tied up tourniquet style to almost popping. I enter the room with my strap-on dangling beneath my lab coat. I show it to the lab rat and laugh before kneeling behind her pushing a gag into her mouth. I grope and taunt my pretty prey telling her how much fun we are going to have doing this orgasm experiment and how she was going to cum like never before but first the warm up. Terrified Luna struggles on her knees anticipating the torment to her helpless body. I untie one leg and bend her over the bed and my cock into her tight pussy. I fuck her hard simulated until she's almost ready to cum then I pull out and give Luna's ass a serious spanking with the leather paddle for almost ruining my experiment by cumming too fast turning her ass a nice shade of red before fucking her again simulated stopping at the point of orgasm. I tell my test subject we need to escalate things a bit. I swap out her gag then get her on the bed for the ride of her life. Luna's bound body is on top of me. I grab a hold of her small waist and her to ride me like a cow girl. Let the orgasm experiment begin. Luna bounces up and down slowly rocking her hips and begins to get turned on. I can see her body betrays her as the first orgasm builds and she explodes on top of me. I have her ride me reverse cow girl style to see how the change of position effects the orgasm experiment. Luna rides me hard as she begins to cum again and again. I take some mental notes for my logbook and I am happy that my captive test subject has succeeded in having more orgasms than any other. This turns me on more than anything ... I grunt and groan as the orgasm takes over my body cumming explosively. I look up at Luna ... what's wrong wasn't this fun for you too. I laugh as I have yet another orgasm with helpless Lana riding my cock.
