let it go

You are still invisible and continue taking the cock in your throat. He worries as he see his cock totally disappear, but he doesn't stop. He grunts a bit as you finger your pussy. You are becoming dripping wet. He starts to shake a bit and comes.

He can see his cum coat your throat. Your stomach become visible with the cum covering it like it's an X-ray. He shoots his load again. You swallow and your stomach becomes invisible again. He sees a visibly come-covered tongue lick your lips.

You move away from him.

"Wait! Where ... are you? ... What are you?"

You smile. You open his desk and take out a magic marker. You make a small circle around your ass and pussy. Just small enough to wipe off if you choose to disappear.

"Come on hit the spot," you say.
