You pull the long, thick vibrator from the toybox and position yourself on the bed, kneeling between her legs (currently forced apart by the handcuffs on her ankles). Her pussy is glistening in front of you, and you turn the vibrator onto its lowest setting. You trace a line down her back with it, and she moans into her gag as you let it circle around her buttocks and down her legs, before it moves back up her inner thighs in turn, never quite touching her moist, waiting pussy...

And then you hold it against her waiting clit, and she writhes in her bonds, her hands clutching downwards, trying to reach the vibrator, but she's completely helpless, unable to do anything about the pleasure you're giving her... you move the vibrator to her labia, and stroke it up and down before letting it briefly push inside her... and then you withdraw it, and turn it up a setting, and push it back inside her...

The effect is immediate, and she bucks, moving as you thrust the vibrator into her, her moistness easing its movement inside her as you turn it to its highest setting and pump harder, watching her body move as much as her bonds allow her, responding to your stimulation with complete arousal. She's grinding against the vibrator now, taking as much control as she can over her arousal, simultaneously pushing her clamped nipples into the bed underneath her as she writhes, strains, struggles and wriggles her way to orgasm...

She's panting as she finally comes down from her high, and you remove the vibrator from her. You decide that it's your turn to cum. But where?

Your choices: On her breasts or In her pussy or In her ass.
