The Training of Kristine, Day Two

Day Two. Kristine walks in the door like she's still in last night's dream. Her black hair sticks to the sweat on her neck. He grabs her by the wrist, yanks her forward, bends her over the leather bench without a word. His cock's already hard, thick and heavy, swinging between his legs. He works lube into her ass with two fingers, stretching her open while she breathes through it, knuckles white on the bench. When he pushes inside, she grunts, shoulders tense, taking every inch. He doesn't go easy. Each thrust drives deeper, her athletic frame rocking forward with the force. The chain around her wrists rattles every time he slams home. She bites her lip until it bleeds, but she doesn't ask him to stop. He keeps going until she's shaking, sweat running down her back, until the only sound in the room is skin on skin and the low, broken noise she makes when he finally comes.
