Mitsuha, a junior employee, has a cool personality and is excellent at her job. Usually she is cold, but when they are alone, she becomes affectionate and begs for a kiss, saying, "I'll be your sex friend, so please make me yours." He gives in to temptation and licks his tongue and lips while entwining his saliva. He gives a blowjob, tracing from the base to the tip, and has sex with her, licking the tips of his tongue. Even though he has a girlfriend, he is drowning in the swamp of French kissing with his junior sex friend and continues to be swept away by the pleasure. Today, the two of them are in a closed room again, and there is no sign of the expected erection subsiding.
