"Finger"

Mollie leans back on one hand, her other slipping quickly across her hips and onto her mound where she rubs in a great circle, her flesh following her hand. Mark watches this for a moment, then makes eye contact and says "good girl" and leans back into the pillows, closing his eyes. Mollie smiles as her eyes drift back to his cock, and she slides two fingers between her lips and into her wet hole, following her imagination. She draws the moisture back out and spreads it over her warm sex, sliding up to straddle her clit with her fingers, drawing it up and out and eliciting a tremor in her hips at the sensation.

Mark drifts off to the quiet, slick sounds of Mollie's sex, waking only slightly as she climbs off him and puts her head down next to him.
