You have volunteered to be a human lab rat in my clinic. We are experimenting with male arousal. I am specifically interested in cultivating a serum that will allow any and all men to experience an orgasm hands free. You've been here for days, being poked and prodded, worked to extraordinary heights of arousal. You have been utterly reduced to a sweating, rutting bitch in heat. You are desperate to cum. You are also desperate to leave my lab, but I won't be letting you go until I get the results I desire - no matter how long that takes or how maddening the methods!
