Ms. Hasumi is on a home visit as the student's homeroom teacher. When she listens to the student's troubles of poor grades, she learns that he is feeling horny and can't concentrate on his studies. Taking advantage of the student's parents' absence, she engages him in a passionate and intense French kiss to try to clear his Kokoro and body. Their saliva intertwines, their tongues entwine, their lips shining alluringly... The student gets an instant erection from the lewd slurping sounds of their naughty kiss. Ms. Hasumi's amazing tongue technique makes the student cross the line between teacher and student!
