He is so lucky she is a nice person. She could have spun a major victim story about this incident. Harry would have gone to town if he was her, as shown by how he insinuated he was a victim in the situation as it is.
She's a low level employee, he's wealthy bosses wealthy, prince son.
She was very drunk (she sounds consensual but very easy to add a few words just to raise question marks about consent).
The "satisfaction" was almost definitely one way.
She thought they were friends, he didn't contact her again (pump and dump).
Never mind the myriad of things that can be implied from unprotected sex.
He - and his father - should be thanking her!!
