A runaway boy who was picked up by his sisters and became a pet. The one who picked me up was a slutty sister from the neighborhood. "You can stay at home. Instead, don't refuse sex."

The one who picked me up after I ran away from home was a slutty sister from my neighborhood. He is under the contract that "it's okay to stay at home. Instead, he doesn't refuse sex," and he continues to have sex when he is at home. The sister and sister come in one after another, and while she is eating with her parents, she has sex with her sister. When my sister is watching over her parents in the living room, she has sex with her sister, so she takes turns coming to the room and does it. Thanks to this, my sperm is always empty.
