Extra Credit

Zoe knocks on the door with the box in her hand. Tina opens it wearing nothing but a black slip, takes the box, and leads her inside. She peels off Zoe’s clothes, slips black lace onto her skin, and binds her wrists to the bed. The ball gag goes in next, quieting every sound. Tina climbs over her, hips to mouth. They lock into the 69 position, tongues working without mercy. Zoe pulls against the rope and comes hard, over and over, her body jerking with each rush. When Tina is satisfied, she pushes Zoe’s head back down and rides her face until both of them break again. The grade is sealed.
