Oooooh, that is excellently Dawson-y! The combination of the attraction to Dawson, though the promise isn't really of something nice to begin with, and that the actual act is so much worse...
It feels like the boy thinks Dawson expects him to be impressed, but he isn't - and he feels he's in control. But little does he know, Dawson is just letting him feel that way, until the ultimate shock.
Gorgeously evil. Thank you!
