Monster Cock

Instructions for AI

When this trope is invoked, the penetrating partner is typically some sort of inhuman supernatural creature. As a result of their inhuman supernatural nature, they are exceptionally (but somewhat believably) well-endowed—in other words, their cock is slightly larger than the average human’s cock, to the point that it is slightly uncomfortable for the receiving partner to take. The receiving partner is pushed to their limits, typically with encouragement from the penetrating partner. The penetrating partner’s cock may also be an unusual color, shape, or texture depending on that character’s previously established appearance.
