KGDV-041 - Sold off by my brother, now I'm a toy for my father-in-law and brother-in-law

It's a drama, but the ending is predictable and not very erotic. Couldn't they have made Sena-san's casual outfit a bit sexier? In the scenario, she wears the same clothes even when the days change. Also, since the mother character was introduced, I wish they had included her in the action. I'm only giving it a high rating because of Sena-san's reactions.
