Relax for a bit

Mark gestures toward the couch, and Mollie obediently sits, with an upright posture, hands flat on her thighs and breasts standing proud. He has always had the sense that, aside from her constant appetite for sexual stimulation, Mollie wants to be a useful part of the household and takes satisfaction from performing whatever tasks Mark asks of her. She knows several commands, but also learns from context. At the moment, she's expecting a chance to help Mark relax while he watches the screen and presses buttons.

Mark kicks off his shoes as he starts up the game console, setting the controller on the arm of the couch. He unbuckles his pants and begins to step out of them, and Mollie breaks her composure when she the bulge of his dick is revealed. "Ah, ah!" he scolds, and she returns to her pose, her eyes following his hands as he removes his underwear and the object of her fascination appears. Folding the clothes and placing them aside, he drops into the couch and picks up the game controller and headset. A glance at Mollie shows her still at attention but with eyes on his dick and her mouth slightly ajar. He navigates the menus, checking back until finally Mollie remembers herself and meets his gaze with a pleading look. Mark waits a beat and says softly, "ok, Mollie."

With a start, she returns to the floor and crawls between Mark's spread legs, humming softly. She glides her hands over his thighs, converging on Mark's dick, and he spreads a little wider to accommodate her shoulders between his knees. With practiced hands, she caresses his thighs and chest then traces lightly up and down his shaft, watching intently as the tip creeps slowly higher. Mark, meanwhile, is engrossed in the game, having rejoined his party, and presses Mollie's head down so he can see the full screen.

Mollie leans forward to lick under the tip of her plaything, her eyes flitting up to Mark's, but he does not register her presence. As his girth fills out to its familiar, slightly curved form, she re-positions, briefly cupping her breasts to rest them on the couch cushion as she positions her mouth to take him in. Daintily, she tugs the dick away from his chest and kisses the tip, the center of her little universe, and slowly rolls her lips around the bulge of his cock-head, while her right hand traces up the back side of his balls. Her lips slowly close around him and she begins to run her tongue side-to-side. Subtly, automatically, Mark's hips shift forward, showing her she is doing well, and she hums contentedly.

As the game continues and mark converses with his friends, Mollie slides ever lower, wetting and warming Mark's cock. Her tongue traces out the patterns she has learned through practice and instinct, as she strokes his sack gently. Reaching the end, she begins a cycle of retreat and advance on his shaft, knowing from experience that moving too fast will earn her a reprimand. But the shape of Mark's member in her mouth, the wet friction of his flesh, has aroused her too, and the fabric of the cushion on her nipples with every down-stroke only adds to the sensation. Her hand snakes down between her legs and presses flat against her warm sex, before she remembers being corrected for the same mistake so many times before. But Mark has not noticed, and she returns her hand to his thigh as she continues to slowly stroke him in and out of her mouth.
