Service Day: Sin's Birthday

Sin stands in the cold drill court while the House gathers. The air bites her bare skin. Her birthday present is work. They put her through it hard. Every rep earns her the next round. Her chest heaves with the effort, sweat mixing with the chill. Black hair sticks to her face. When the last drop falls they turn her. Hands bind her wrists to the post. She feels the rope bite. They open her ass first with oil and fingers, then they fuck it deep. Every thrust slams her into the wood. Between strokes they lay the strap across her back, her thighs, her tits. Each mark is counted. She takes them all. By the time they finish, the cold has nothing left to take from her.
