これが甘さの意味です

Yui Takahashi is a beautiful schoolgirl who has just grown up and secretly desires her father. After talking with her friend, Yui is kept behind by her teacher Hiroshi after class. The teacher presses her against the blackboard, spreads her legs wide and thrusts his big thick cock deep into her tight young pussy. The brutal thrusts make Yui writhe in pain with tears in her eyes, but her body trembles with strange pleasure. Teacher Hiroshi keeps pounding her hard and deep, making Yui moan uncontrollably.
