Submissive ebony beauty zippy aka miss Nairobi deserves a treat and what better way than to treat her by tying her very tightly and securely to a chair with a vibrator between her legs. Thinking she's being punished I start by stuffing her mouth with a large white handkerchief and then tightly winding some pvc tape around her head to prevent her from spitting out the cloth. Once I'm happy with the gag I slide her leather gwendoline hood over her head and begin to lace it up at the back, making sure it's nice and tight before placing a posture collar on her. Now completely helpless and unable to move all she can do is stare at me from the hood with them pretty dark eyes of hers. I reach down and switch the vibrator on and instantly she squirms with pleasure as she grinds on the vibrating wand that has been tied to her crotch. I let the vibrator work its magic for a while before I cruelly switch it off and watch her get frustrated. I don't leave it switch off for long and she instantly groans with pleasure. I leave her to with in ecstacy before turning the speed up another couple of notches and watch her really squirm. Her moans and groans get louder from beyond the tight leather hood and gag as she is unable to hold herself together, she begins to shake as as the vibrator takes control and she gives in and hits her climax and cums really hard. I switch the vibrator off and let her rest and catch her breath, her hear still fuzzy from the orgasm. After she has calmed down I untie her and let her remove her own hood and gag, peeling away at the tape to reveal the now fully wet hanky that filled her mouth.
