There is a story where a woman has another woman as a slave. The slave is in a box at the end of her bed. There are holes in the box that the slave can see into the room. A man comes in and laughs about the slut in the box. The woman is like, oh, no one, you can take her out if you want and fuck her. Or she can blow you. Just stick your dick in a hole. Turns out the man is the slaves brother and she has to choose to come out naked before her brother or blow him to keep her identity secret. Something along those lines. Any help would be appreciated. Should have saved it years ago.
