Sensei and Makoto are in the back room of the porn shop. He brings up what happened the last time they were there, and their other occasional activities — Makoto claims that she does such things "for science" and for stress relief, not for pleasure, but eventually admits that she has become turned on while talking about it. He gets her to give him a blowjob, but declines her suggestion that he "put it inside" her, saying that it will be more satisfying if she waits.
