Pre-programmed.

Josh was great at two things.

Research.
Watching Porn.

The two coincided when he found a very old video of a Woman hypnotized to suck cock on command.
She looked like...it can't be...

It was the School Librarian.

He got her to leave her Station with him to find a Book at near the end of the School Day.

"What's it called," she asked him.
"Suck."

Her eyes glaze over and she drops to her knees.
He presents his cock to her and she sucks it!

He cums after a couple of minutes.
She swallows it on command and he puts his cock away.

He wakes her and she acts like nothing happened.

After she leaves, he makes a mental note to see what else they hypnotized 'Ashleigh Madison' to do back in the late '90s.
