He is tied up / restrained / bound on a chair where he cannot move, talk, or see. His gag can be anything that keeps him from talking. You will both start out naked for this part, and you will now be wearing makeup and jewelry you own (such as a choker necklace, hoop earrings, and bright red lipstick please) along with sexy heels (heeled boots would be very sexy) to fit the domination / BDSM theme / vibe. He will start out with no erection / completely flaccid, so we can see his cock get harder and grow to be erect during the video. You do things to him such as suck and lick his cock and balls, cradle his balls, jerk him off, deep throat his cock, ride his cock, slap him, bite, lick, suck, and kiss parts of him, run your finger nails over / scratch him, spit on him, even flick / hit his cock and balls, and whatever else you may think of to use him as you please. His portion of the video will end with you giving him a ruined orgasm, where right before he cums you stop touching him and hopefully he cums on himself. You both get very handsy with each other, rubbing your hands all over each others bodies and privates, as you belong to the other one. End scene by walking away from the one restrained like you are being left alone.
