To the headmaster's office

The headmaster's office is on the other end of campus, so Leo leaves his dorm, putting on music and thinking about the day so far.
The serum had worked way better than anticipated. The possibility to control their minds seems to set off instantly. He still didn't know how long the effect lasted. It could be permanent, it could wear off in a day or so.... Leo wondered whether the strength of the effect would increase with additional doses. So far, the girls had been very receptive to his commands. He wondered if there were any limits to the control. None of the girls knew what he was doing or that he was doing it to others aswell.
If the **** lowered the brain's awareness to social norms, the possibilities were endless... a dorm orgy, his own harem, a better apartment...

While Leo makes his way around campus, his gaze is caught by beautiful women all over the college.

A stunning brunette with a red top smiles at him, showing off her perfect teeth. He winks at her and she blushes.

He makes a mental note to find out who this girl is. Oh man, this serum really is a life-changer!
