Kiss of Judas

A sex move where you suck his dick, make him think you swallowed, go in for a kiss and forcefully blow all the cum into his mouth.

Hey Karen let's go clubbing.
Clubbing? I thought you had a boyfriend?
Nah. He dumped me after I gave him a Kiss of Judas.
Why the hell would you ever do that to anyone!?
It was funny.
