What I liked was how he didn't try to make those two girls into sex slaves by fucking their brains out or exposing them for extreme pain - he did it by exploiting their love towards him, by making one envious and maybe even jealous of the other.
The sex scenes weren't done the way you might expect them to be done. They weren't intense or anything, but rather came off as calm, and even a bit romantic - which again makes me wonder - did he really love the girls or not?
If I left the answering of that question to the music, it would be a definite yes. It's just calm, romantic string music that screams love a long way.
The animation is good too; with good details in the surroundings and great character motions, but it suffers from a bit old character designs. Sex scenes were done very well too.
In all I feel Teacher's Pet is different from most hentai out there. Despite having a guy who's after making the girls his sex slaves, at times I felt it was more about the love than the lovemaking. If you're a hentai fan, give Teacher's Pet a try.
