Current female college student: Private tutor who is weak to push

Nishikawa Yui, a current female college student, will be a private tutor to male students! However, Yui-sensei, who is weak to push, cannot refuse students' naughty requests. Students who are concerned about the teacher's body and are unable to concentrate on their studies are begged to give them blowjobs, handjobs, and even sex to help them feel refreshed! Yui-sensei's special lessons have skyrocketed in her dick and grades! ?
