Reiko (46 years old), a married woman whose husband lives alone and lives alone, is an exercise instructor at home. He is currently teaching two students, Miyazaki (40) and Okumura (21). Okumura can't help but worry about Reiko's too sexy appearance and pose. On the other hand, Miyazaki takes lessons seriously. Okumura is jealous of Reiko, who is gently teaching only Miyazaki, and goes home first. Reiko and Miyazaki, who are alone, are in a strange mood, and Reiko sucks Miyazaki's things. A few days later, when Okumura sees the two in love, he wants to join them.
