Sucked to Climax by the Gimp

I've secured my submissive twink in a harness, wearing a gas mask, and added more restraints to heighten his vulnerability. I inform him that I have a surprise in store: I'm bringing in a gimp to suck him while he's suspended, but I emphasize that I control his orgasms; he must ask for permission to release. I guide the gimp into the dungeon and position him on his knees to begin pleasuring my slave. I insert the tube from the gas mask into my trousers, allowing my slave to inhale my scent as he nears his climax. With added stimulation from a vibrating wand, he requests permission to come, which I grant. He climaxes onto the gimp's face, who eagerly licks up every drop.
