The Training of Amber Keen, Day Three

Amber pushes past the pain. Her knees shake. Sweat slides down her spine and pools at the small of her back. She’s on all fours, ass up, trying to breathe through what he’s doing to her. He’s got one thick finger buried past the second knuckle, working it in slow circles, opening her up. Her hole flutters, tight, then wider. She wants to say stop. She doesn’t. She wants to say more. She stays quiet. The stretch burns, but it’s the kind that sticks with you. He adds a second finger. Not gentle. Just steady. She arches, bites her lip hard enough to taste blood. His cock rests heavy against her thigh. She can feel every vein, every twitch. It’s too big. She knows it. She still pushes back. He grabs her hair, pulls her head up so she has to look at herself in the mirror across the room. Her mascara is a mess. Her mouth is open. She doesn’t recognize the girl staring back. He leans in close, voice low. "You’re not done till I say." She nods once. He keeps working her open, slow and relentless, like he’s got all day and all night. Her thighs tremble. Her cunt clenches around nothing. He doesn’t touch it. Not yet. This is the lesson. This is Day Three.
