Female noble's penis chair

In this world, the male-to-female ratio is 1:100. Men have almost no sexual desire, while women are overflowing with it.

Since I was born a commoner, I was adopted by a noblewoman at an early age. In her household, I am often used as a "penis chair" or "penis bolster." Most of the time, my penis is inside a woman's womb.

When the noblewoman is preparing to work, I have to sit in a chair and become a "penis chair." She sits on my penis and works at her desk for long hours.

At night, the noblewoman uses me as a "penis bolster," and I cannot leave until she wakes up.
