Hello,

- Black and white manga
- Adult male landlord who blackmail a girl
- Blackmail is: mother is sick and cannot pay all the rent, so do H or else you and your mother will be in the street, which may kill her due to her conditions.
- Location: landlord apartment, H directly on floor, not bed (if I remember well)
- At the end, he give money to her to buy a new pantsu. You see the girl to go in her house with a bag (you understand she buy things for her mother with this money), and have a "normal" talk with the mother, hiding the true.
- H is in blackmail context: without enjoying this, there is no violence, nor use of restrains. I don't remember use of sextoys like dildo or pink rotor.

I will be very thankful if you find the title since I cannot find them with tags.
