Let him take control

Struggling to lift her head, Sandra eventually gives up and places her hands behind her back. Frank tangles his fingers in her hair and lifts her head, letting her breathe before pulling her down again.

Sandra relaxes her throat and feels the flare of the head of his cock slip past the back of her mouth and into her throat. She gags on his cock which only excites him and he tries to push deeper. Sandra thinks she is going to pass out when he pulls her head up. She gasps and coughs, her spit covering his cock and balls.

Frank pulls her back down, filling her mouth as her starts to fuck her mouth in ernest. Every few thrusts he buries his cock, invading her throat. "Gag on it slut. I'm going to make you my full dump."

Sandra whimpers around his thrusting cock. She tries to move one had from behind her so that she can rub her aching clit.

Frank slaps her cheek. "No slut. You can't touch yourself right now."

Stunned Sandra puts her wrist back behind her back and looks submissively up at her boss.While his smile gets more wolf-ish, the lust in his eyes is obvious. Now as he uses her mouth he is much less careful, driving in to her throat each time. Soon he is grunting and pulls her all the way down his cock. She can feel his cock pulse before each stream of cum is shot in to her throat.

Sated he lets go of her head, but Sandra holds off on pulling off his cock until she has to breathe. After a few quick breaths before she attacks his cock again, this time lickeing and sucking all of the spit and what little cum she didn't swallow until he was clean.

Sandra rocked on her heels, her pussy wet and engorged. She could feel her pulse in her clit.
