An improvised slut live show from FANZA! Teacher Reiko calls a student to test whether he can control his ejaculation. When the teacher seduces him with sexy words and her breasts, he gets an instant erection, but when she focuses on his nipples with her tongue and nails, they are already sticky with the teacher's saliva. When she stimulates his erogenous zones with a handjob and nipple licking, he comes close to climaxing many times, but is stopped just before it. On the bed, she gives him a sloppy blowjob and a high-speed drooling handjob, bringing him to the brink of exploding, saying, "If you want to do it, then hold on," and then she moves to forced cunnilingus and then intercrural sex, bringing him just before it. Once inside, she thrusts vigorously in cowgirl position, bringing him just before it reaches the point of ejaculation. She designates the spot on his tongue for him to drink, the semen manager.
