Invisible blowjob

You watch him jerking his cock. He still can't see you, due to your invisibility. He is watching a threesome on the computer. His cock is very meaty and glistening with pre-cum.

Your nipples become rock hard and you start to get wet. You come up with a delightfully wicked idea. You spin his chair around. You stand in front of him. He has a scared look in the eyes. You can see him trying to figure out what's going on.

"You have been a dirty boy," you say with a smile and a lusty voice.

"Who is that? Who's here?" he shouts, confused.

He pulls up his pants and looks around. You lock the door. He looks panicky.

"I am the ghost of pussy past," you say, laughing.

You push him on the bed and then pull down his pants. You take his cock in your mouth. He watches in amazement as his cock seem to literally disappear. You start to stroke and suck his cock as you put more and more in your mouth.

"Ohhhh, Shit! That feels so good! Mmmmmm!" he exclaims.

You sucks his balls as you stroke it.
