Teaching Sienna

Minnie pulls Sienna to the edge of the bed and slicks her hand with lube until it shines. She works two fingers, then three, feeling the wet heat clutch around every knuckle, before she tucks her thumb and pushes farther. Sienna’s lips part on a broken moan. Four fingers disappear, then the whole hand slips past the ring of muscle that yields and swallows. Minnie twists her wrist, slowly, deliberately, until her knuckles press that swollen spot inside and Sienna jerks like she’s been shocked. Every slow withdrawal drags soft walls with it; every slide back in fills her deeper. Sienna plants her heels, angles her hips, chasing the thick stretch she has only ever given herself. Minnie watches, eyes bright, and opens her hand inside her until Sienna’s belly tightens and she starts to shake.
