Parasitic Dick
I get it, the title sounds crazy right? But it's true! I swear my cock is a gluttonous pig, a demon, a parasite! I myself am a very mild mannered, kind, loving and respectful person. The only issue is, my cock loves to control me. Once it's hard, or backed up, it takes over and it only cares about what it wants. I try my best to fight the urges, tell myself I'm stronger than it, but I'm not. I will go from doing whatever normal activity I was doing prior, to being laid out with my crotch covered in oil, tongue out drooling, with my hand tug fucking my dick while my tip spits precum all over my stomach. It really feels like I'm possessed by my own penis.
