Choisuji

Based on the manga by Asaki Takayuki.

The very first volume tells the tale of precisely how an instructor works on the magical hand puppet to trick a girl student into giving him a handjob, a blowjob and... let's just voice it out won't end there.

The second volume tells the tale of the way a female student and the male school doctor undergo a great length with an urinal sample away from another female student.
