You don't. But it's a struggle not to.

It's everything you can do to pull your cock out of her throat and let her breath. She coughs, retching, spilling a stream of spit and phlegm onto the floor as she continues to quiver and shudder. A dark and terrible part of your mind wants to ram your cock back into her throat and hold it there until she gets the erotic **** she seems to be fantasizing about, and it takes an effort of will for you to turn away from her.

Your cock is aching from her young suck mouth and Rose's grasping cunt, but you know it will take some steady fucking before you build up another load to dump into one of your two otter bitches. You also know that it won't be much longer before Brian comes home, which will almost certainly mean that he joins in. You certainly don't have any objection to sharing these two manipulative bitches, but it will take some time, and you remember that the two of you have a dinner engagement with your neighbours.

It might be best to leave these two wanting more, for you know that as long as they feel their mission is to distract you they will be back for more tutoring. They seem to surrender quickly to a need to be dominated, even brutalised, and your cock twitches as you anticipate much more fun to be had with them in the days to come.

Their eyes are looking at you with wanton desperation, Margot still drooling slime from her mouth, both of them wriggling invitingly as much as their bonds allow. It would be so easy to use them again, so very easy to violate their holes, so very satisfying to hear these arrogant rich brats beg for more.
