All kinds

Eric kneels between Jesse's legs and unlocks both spreader bars. Then he does the same for Nicole. He stands and helps each girl to her feet. Both stand with their heads down. Eric steps back and forth in front of the two of them.

"When you stand before me," he says, "I expect you to stand a certain way."

"Yes, sir," both girls say in unison.

Eric starts with Jesse. He pulls her arms behind her back so that each hand is grasping the opposite elbow. This pushes her chest out and forces her to stand up straight. Then Eric crouches and nudges Jesse's legs apart.

"Your knees should always be shoulder width apart when you're in my presence," Eric instructs.

Nicole watches as her sister is manipulated and tries to copy her pose. Eric steps away from Jesse and stands before Nicole, inspecting her. "Very good, my pet," he says, reaching out to stroke her cheek. "You've come a long way in a short time."

"Yes, sir. Thank you, sir," Nicole says.

Eric claps his hands together. "But now, I must prepare you two for bed. Soon, you will learn to do these preparations on your own, but for now, I will do them."

Eric walks to a chest against the wall and opens it. He reaches inside and pulls out two bags. He sets them on the floor in front of the girls, one in front of each other them. "These bags will contain your nightly routine. Once I have chosen a name for you, it will be embroidered onto the bag. For now, you must remember which is yours by color alone."

Eric retrieves the testing bin and pulls out the two sets of buttplugs. He selects the plug that is one size smaller than the one the girls currently have in. "You will sleep with a slightly smaller plug to keep your hole stretched," he explains. Eric reaches back into the bin and pulls out one of the inflatable dildos. "Your measurements will be sent to a specialty store where dildos to your exact specifications will be made. Until then, however, I have something else to keep your pussies entertained at night."

Eric hurries to a wardrobe and searches through some boxes before returning to the girls. He holds up two small egg shaped objects. "These are vibrators," he explains. He reaches towards Jesse and holds it up to her face. "Open," he commands.

Jesse lets her jaw drop.

Eric pushes the vibrator completely into her mouth and then raises her jaw with a gentle hand. "Suck on it," he commands and he repeats the process with Nicole. Both girls swirl their tongues around the vibrators, covering it with as much saliva as they can muster.

Eric holds his hand in front of Jesse's face again. "May I have it?"

Jesse lets the vibrator fall from her mouth to his hand. Eric takes the dripping egg and reaches it between her legs before guiding it into her cunt. He does the same to Nicole. Then he picks up the pair of buttplugs and steps behind them.

"Bend," he commands, placing a hand on the small of their backs and guiding them forwards. Both girls bend stiffly, neither taking their hands out of position. Eric turns to Jesse first. He twists and pulls at the plug already embedded in her ass until it pops free. Then, without reapplying lube, works the bedtime plug in until its firmly set. He does the same to Nicole.

"And now for something to keep it in for the night," Eric says, returning to his wardrobe. He extracts a pair of belts. Each belt is made from fine soft leather and had a strap that hangs between. Eric wraps the belt around Jesse's waist, above her hips, and tightens it. He locks the fastener in place with a small padlock. Then he pulls the strap between her legs and tightens it as well. It pulls up tight against her asshole and cunt and forces the plug and vibrator to stay in. He does the same thing to Nicole.

"And one last little thing before bed," Eric says. He pulls a thin leather collar from the bin and pulls it tight around Nicole's throat. He locks it in place with another padlock. "It's not as fancy as your sister's, but if you put in enough effort you will be promoted to a jeweled collar in no time."

"Thank you, sir," Nicole says.

Eric attaches a leash to each of the girl's collars. "Follow me," Eric says and then, as each girl takes a step, "No. Crawl behind me."

Both girls drops to their knees and crawl on all fours behind Eric as he leads them back through the door and into the hall lined with cages.
