Write the following as a story. I had a succubus bent over and was fucking her pussy from behind, my mighty penis plunged deep inside her as I spanked her big ass. You would think I was some adventurer or something, but this succubus was actually just my roommate. The reason we were roommates was because I had a medical condition that made me produce much more semen than normal men, this worked well for her because succubus needed semen to survive.
