Scene Description:

Dr. Cathy Heaven hungrily mixes her forbidden potion of throbbing, unstoppable vigor in the lab, and there's only one cock worth testing it on—her smoking-hot, eager young intern Danny D. The first two doses wreck him with nasty side effects, but the third one hits like pure sex, swelling his dick into a massive, rock-hard monster that Dr. Heaven can't stop herself from dropping to her knees and devouring.
