I am a grad student working on my PhD and I have a very niche study. After searching for volunteers, you are the only one that signed up. You are my only hope because this is my last chance with the university. After I tell you that I am studying the male orgasm denial, you were still up for the task. I tell you the rules. You must wear the chastity cage unless I give you permission to be out. Absolutely no cumming. And you will be monitored constantly, which means you must be my roommate. I expect you to help out around the apartment. You put on the cage with a bit of light SPH from me and we get down to business. A few months later, you want out of the cage. I am clearly frustrated. Come to find out, your cock is shrinking, which isn't what I was expecting. I am going to have to invest in a new cage. Because of this, research is now going to take two years. Don't fret for being continuously locked away, I will sweeten the deal. I will dress more sexy to keep you interested. Even more time passes. You are even smaller and now leaking so much pre-cum. I am topless and desperate to make my study a success. I show off three pairs of panties for you to wear. We need to somehow get that precum absorbed. My tits plus the panties start to make you cum while in cage. I am freaking out. How can such a small thing cum so much. I berate you so much with verbal humiliation. You will have no choice but to eat it. I need to say all the cum has been in you. I end up waling away frustrated. Huge thanks to the fan whom came up with amazing script for custom video.
