I don’t have pictures but need help finding hentai title

This hentai has a guy who is given this magic mirror basically. It’s about the size of your palm and its circular and it’s actually a one way portal to whatever you want. With the mirror, you guessed it, the kid goes on a raping spree and just fucks every girl he can think of. There are some scenes where he fingers and fucks a girl during class and stuff. Yeah. That’s about all I can remember. Any help appreciated!
