"Mount"

Mollie leans on Mark's chest with one hand, pulling herself upward. She wraps the fingers of her other hand around his shaft and deftly lines it up, stroking it briefly between her moistened folds until it catches on her hole, then sinking rapidly, engulfing its length inside her.

As the fullness she has craved since this morning overtakes her, she sighs and melts a little, leaning forward so her breasts dangle over Mark's face. She is still watching his face for guidance.

Mark leans forward to take a nipple in his mouth, running his tongue around the hard nub before pulling the soft flesh into his mouth. Mollie remains still, as she has been trained, but rhythmically grips Mark's cock with her pussy as his mouth tugs on her breast. Mark feels the ripple of warm, strong flesh surround him, bringing him to full attention, as her breath catches in anticipation.

Mark waits another beat, then releases her breast and grunts, "OK". Mollie lifts herself until the ridge of his head meets her entrance, then drops her hips. Repeating this motion a few times, she slowly tilts forward to press her sensitive clit against his pelvis with every thrust. With each beat, she leaves more of Mark inside, until she is rhythmically grinding against him, her muscular walls gripping and releasing him in time. With a few quiet squeaks, still staring wide-eyed into his face, she brings herself off. She pushes firmly onto his cock and spasms around it for what seems like hours, Mark enjoying every sensation from deep inside her.

Mark pushes Mollie back up to a sitting position, and she puts her hands behind her on is legs to support herself. The sheen of sweat on her breasts and face shines dully in the light from the window.

Mark knows what comes next - Mollie is a creature of habit - and it invariably brings him off. Mollie cocks her hips back, dropping her ass between his slightly-spread legs, and begins to rock. Cock and ridged pussy stimulate each other. Mark's gaze travels down the chest of his pet to where his member disappears into her blossoming folds, the pink flesh draping gracefully around him. Soon her squeaks return, and Mark grunts softly as the pressure on his cockhead brings him swiftly to orgasm. Molly again descends to consume him entirely and shudders around him as he pumps into her. He raises his hand to signal her to stay still.
