wanna-sub 

someone who pretends to want to be a submissive in a Dominant/submissive relationship, but who actually is interested in kink, not service.

Beginning his sentence to the Mistress with, "i want...", he proved not to be submissive at all, but just another wanna-sub who'd done no research into the reality of The Scene; his interest was purely pornographic.

Soft-Sub 

A Soft-Sub is a person (typically male) in a sexual encounter that enjoys being the "top" but not putting in the work. These people enjoy the pleasure of receiving, however the type of receiving is sort of submissive to them. A close example would be defining the man who is receiving a blowjob

Guy: "Yeah, I'm a Soft-Sub"
Girl: "Oh, that's great! So I'll give you a blow job as well as ride you tonight."
