The premise of the story is as solid as any of the rest of the Burton and Cyb stories – an old man is looking for the daughter he sold into slavery to the man who looks like a vampire. So Burton and Cyb head off to a space brothel to find her. Her distinguishing mark is, of course, a heart-shaped birthmark on her inner thigh. This leads to several hilarious sight gags about them looking at the inner thighs of dozens of prostitutes.

This page is notable for the shape of the space brothel in the bottom panel, especially the main hanger. It is entirely possible that I stole this design choice for one of my space opera pitches. To be fair, it is REALLY obvious.
