Chiaki summoned her stepson, Koji, using the excuse of a broken air conditioner. She had been using him as a convenient lover by having him cover her debts, but today she was surprised when Koji asked if he could sleep with his senior who is also a creditor. Chiaki was disgusted by this outrageous proposal, but reluctantly agreed when Koji said 'I will participate too'...? The first episode is filled with a mix of calculation and desire. Additionally, the second episode featuring an unrighteous son and a devoted stepmother is included! This is a must-see!
