Wet squelch echoes as finger drives in. Couch cushions sink under her shifting weight. Thighs clamp then part wider. Knuckle-deep strokes hit that spot — she tenses. Hips grind up greedy. Pussy lips grip tight around the plunging digit. Breath hitches sharp. Body arches off the fabric. Slow pull-out strings juice. She dives back in harder. Quivers rack her frame. Couch creaks under the rhythm. Fingers pump nonstop. Juices seep out messy. Climax hits — thighs shake wild.
