This isn't going to work out at all. At least two of the "guys" (any woman responding to this ad should be very concerned by those quotation marks) will interrupt the game and demand the topless DM cover herself up because, "No one is taking the quest seriously! We all have a level 0 Concentration and a level 20 Boner!" The guy throwing the party means well, but this is all wrong. Boobs have no place in D&D unless they're on a mystical creature with like five or six of them all over its torso. If you want the gig, ask for $500 to be their Dungeon Master; $400 if they'll let you skip the game and just perform sexual favors.
