Ofcourse!

Now that you´ve got one, getting another would be a lot easier. Spotting a chubby black woman with large breasts and wide hips sitting in a chair at a small desk, you give your new **** a few short orders. "See that woman over there?" The nods. "You are to go over to her and straddle her lap, pressing your hands down over her mouth so she doesn´t make a sound. Once I´ve collared her you are to release her and get down on your knees next to her."

You **** immediately obeys and walks over to the woman while you follow behind her, pulling out a plain brown leather collar. Your **** straddles the woman as ordered, which startles the woman but her protests are cut short by your slaves hands pressing down hard over her mouth and almost blocking her nose.

While she starts to flail about and try to buck off your ****, you come up behind her and then quickly wrap and buckle the collar around her neck. "Keep quiet and get down on your knees." Your **** releases her, then both of them get down on their knees.
The chubby black woman has a round face and plump lips. Her hair is cut short, almost a buzz cut, her dark brown eyes are framed by a pair of simple glasses. You raise a foot to her face. "Kiss it." Without any hesitation she leaned forward and kissed your foot like it was tasty candy, then leaned back. "Good, now follwo me, both of you."

With that, they both follow you as you stalk the library. Soon, you come upon a slim redhead talking to a young asian man. Based on his accent you guess he might actually have been raised in asia, and he seems to be asking for some help from the redhead. She´s about average height, but with a very slim frame and not much on it. The young man also has a slim frame, but has worked hard to put some muscle on it, as you can tell by the muscles on his visible arms.
It is riskier to take two at the same time, but the reward would be great, so you order your new **** to take the redhead from behind while you and the brunette sneak up on the asian man. In short order your black **** tackles the redhead to the ground, knocking the air out of her, and you and your tall brunette **** hold and collar the asian man, followed by the redhead.

As much as you´re tempted to just keep going until you´ve collared everyone in the library, you know you can´t keep this up forever, so you decide to take 2 more, and then head home. As you´re thinking this, you hear some giggling from the other side of a bookcase. Peeking around the corner you see a large black jock and what seems to be his latino girlfriend. He´s hugging her and is whispering something into her ear.
Seeing as you might not get a better opportunity in the near future, you decide to act fast. You wave to your slaves and whisper instructions to them. Before the couple can react your slaves dash around the corner and jump them. The jock is tackled down by the brunette, the black woman and our asian man, while you and the redhead take down his latino girlfriend. All that escapes their lips is a loud "What the fuck!" before you collar them, and they go silent. Once you´re done you line them up and order them to kneel. First you point to the brunette. "What´s your name?" "My name is Anna" You point to the black woman "Patricia", the redhead "Eleonor", the asian man "Chen", the jock "Dele", and the latina "Isabella". "Alright, now follow me. We´re heading home." They all rise and follow behind you, quickly exiting the library and going back to your car.

It gets a bit crammed with 7 people in your car, even with two in the trunk and one laying in the passengers laps. Nonetheless, you make it back home safe and sound.

Opening the door you see that Sister Sin have been quite busy. The boxes are still there but now they only contain matching content. Marcus is still in his latex suit, but is wearing a straitjacket and a large bulky gassmask with a rebreather bag attached. Sister sin comes out from behind a stack of boxes carrying a electric prod, but stops and bows when she sees you. "Good day my Lord. May I ask how your trip fared?"

You smile and beckon your new slaves forward. "It went quite well if a bit unexpectedly. We now have six new in this household. I haven´t decided exactly what to do with them jsut yet, but I´ll think of something. Dress them up for me, I want my new slaves ready for use quickly. I´ll use Markus in the mean time."

Sister Sin bows again and then gestures to your slaves to follow her in behind more boxes and you hear her undress them. You meanwhile remoce the gasmask on Marcus head, revealing that he´s got and almost jawbreaking ballgag in his mouth. He looks up at you pleadingly...
