After school, childhood friend gal Jun naturally rolls into Sazawa's room. But today, Sazawa seems unusually restless. When asked, he says, 'I got a girlfriend.' Hiding her chest flutter, Jun unilaterally starts lecturing, 'SEX to avoid being dumped by your girlfriend—I'll teach you.' Initially no touching, practical skills are completely air. Sixty seconds of air kissing, eye contact, hands kept above the waist... Each clearance unlocks the next stage of play, and finally insertion! However, premature ejaculation is not allowed until OK is given! A strengthening lesson for a worthless dick dripping with a girl's possessiveness!
