Nope

Amy looked up at me. My glistening cock was covered in her pussy juices and hanging inches from her face. She wrinkled her nose. "You know I don't like to do that," she managed.

"If you don't, no sex next time," I said.

She continued to sit there. "It's not working," she said. "I'm not feeling anything."

I had one more thing to try. I pushed it a bit closer to her and growled, "I said suck it, slut!". Suddenly I could feel a strange feeling, like a light bulb turning on deep in my brain. Amy could feel it too, because she opened her mouth and engulfed my cock.

I stood in her office as Amy, professional mediator and psychotherapist, slowly and methodically cleaned my cock with her tongue. I got hard again while she was doing this, and she then proceeded to start sucking my cock, with loud slurping sounds, until I came in her mouth.

"Wow, that was great," I said. I collapsed on the couch.

Amy got up and sat next to me. "That was excellent," she said. "We got some great data and I have a good idea of how the addiction works. Just a couple more experiments and we can start the project in earnest."
