"Can I have both, Master?"

"Can I have both, Master? I have been very good," Tiffany says with a smile.
"That's true. Just don't think that you'll always get what you want by flashing that smile at me."
"Of course not. Thank you, Master."

Once again, you **** Ms. Ling to put the strap-on onto Tiffany. She seems much less resistant this time, however, only needing to be told. She has more energy this time.

As a reward, you tie her up with her hands in front and sit her on the couch. You have now moved Miko and turned her facing the couch, her legs hanging off of the end.

Tiffany moves in behind her and pushes her still-lubed strapon cock into the Asian Teacher's asshole. It was freshly-fucked by you, so entry was quite easy. She grabs onto the woman's supple hips to get a good grip for fucking her.

You move up behind your obedient nubian **** and rub your cock against her asshole. She rubs back at you, showing her interest. Once again, you remember that you have to make them earn things and not just give them what they want.

"Please fuck my ass, Master," Tiffany says.
"On one condition. You do what I want you to do next."
"Yes, Master. Whatever you want, Master."
"Good. Hands behind your back."

Tiffany takes her hands and puts them behind her back. You grab some handcuffs from your bag and lock them around her slender wrists.

"I control you- all of you," you explain, "When I fuck you, you fuck her. You don't decide how often or how fast- I do."

You thrust your cock into Tiffany's asshole as you finish, literally and figuratively driving the point home. Now then...
