Pull out and rub yourself to climax against him.
From Create Your Own Story
Feeling a need for release, you pull the dildo out from his behind, unstrapping it from your waist with shaking hands. The slave stays exactly where he was as you climb up on your haunches and press your glistening, hairy sex against his bottom. With two strong hands, you push him down into the furs, his body completely pressed down as you straddle above him. With one handing holding his head down, you begin to rub your vagina against him, your quick releases of air from exertion soon becoming panting, your panting soon mixed in with guttural cries of pleasure. You kiss the back of his neck, quickly and sexually as you continue, leaving a slimy wet patch on his bottom cheek as you continue rubbing against it.
Eventually, after what seems like forever, you feel yourself getting closer. With all your weight now on top of the slave, both hands squarely on his back, you scream as you climax, the juices from your sex pouring liberally onto the his fair behind. Breathing heavily, waves of pleasure starting to fade and your touch with reality returning, you roll off of him, looking up at the tent ceiling above.
