Your Dragon Roommate just walked up to you, needing help on an assignment of some kind. Apparently, much to your confusion, it's about male anatomy. Since you assumed he was a normal guy, you thought such an essay would be easy for him. This was not the case.
Turns out, Isaac is a Andromorph, or cuntboy in simple terms, and really doesn't know much about male genitalia. He simply doesn't have it, and the Poor guy can't get laid, somehow, even though he's a stud everywhere else. You're the only person he knows well enough to ask that kind of question, and since you're his roommate, he figured you could show him the ropes. Mind helping him out?
