Stretch Her In More Way Than One

I walk over to the side of the bed that Jen is on and grab her right breast.

"I have to ask you an important question," I say into the voice-changer.
"Wh-what is it?"
"Are you flexible?"
"Y-yes, I am. I'm a cheerleader," Jen says, before immediately regretting it.
"That's good to know. For more than one reason. So, now I have a perfect spot for you. Don't forget to stay still or bad things will happen."

Jen nods and I begin to untie her arms from the bed. I leave the rope loops still around her wrists though. The rope ends attached to her ankles are next to be loosened from the bed. I grab both of her wrists and place them together in front of her before tying them together.

"Now then. I need you to get up and walk down towards the end of the bed. Will you need any help?"
"Y-yes, I will. My legs...are mostly asleep."
"Okay. I will help you."

Remembering the chain that is looped through her nipple rings, I unsnap the end that is going to the fan and reattach it around the rings, giving me a convenient handle for the naked young woman.

"Try to get up first and I'll see how much help you need."
"O-okay," Jen says cautiously.

It is fun for you to watch the young woman's body as she tries to muster up enough strength to stand. She is able to get her tight ass off of the bed, but cannot pull herself the rest of the way up.

"He-help me, please," she moans.
"Okay," I answer, reaching my hand out towards the chain.

Without giving any warning, I tug on the chain, putting pressure on her nipples.

"Owww....stop that."
"I will when you get up all the way."
"Owww...o-kay."

Jen struggles to muster up the strength, but your incentive manages to do the trick.
I let go of the chain, reach your hand down to her crotch and press forward on the dildo in her pussy. I can tell by the **** it takes to move it that she is clenching her pussy very tight to hold it in.

"Good girl," I say, turning the sex toy sideways, "I knew you could do it. Don't forget how nice I can be when you behave properly."
"Th-thank you....master."
"I love the sound of that. Now then, I'm going to need you to crawl to the end of the bed and I'll position you from there."
"Okay."

I watch as she waddles her way over towards the end, trying to keep her balance, as well as the toy in her pussy. When she gets to the end, I put my hands in front of her, grabbing her breasts to stop her. I walk around the side and nudge her ass with my hand, signaling for her to take a step forward. She does so and turns to face forward when prompted again.

"Spread your legs a little," I tell her, "You are going to need it order to balance yourself."

She does as I tell her and I grab the rope end from her left ankle and tie it to one end of the bed. I repeat this action with her right one as well.

"Now, make sure to stay loose. You're going to need it."

She nods hesitantly before I put my hands on her shoulders and press her body forward. This pushes her face right towards Ann's pussy, which is splayed out openly due to the hogtie I put her in.

"Now hold still for a minute."

I undo the chain going through her nipple rings and find a new way to use it. I put one end through one of the loops around Ann's ankles. I run that through her nipple rings and loop the other end through the other one of her friend's ankles.

"You can sit up and stop licking her pussy whenever you want to," I tell Jen, "Of course, if you do that, you will put considerable strain on your nipples. Do you want to test it?"
"N-no, master," Jen answer submissively.
"Good girl. Look at the bright side though: when you press your ass down a little, you can fuck yourself with the dildo still inside you."
"Thank you, master."
"Make sure I don't regret it," I say, giving her a light slap on the ass.

I walk around the side of the bed and pat Ann on the back.

"Are you ready to eat out your friend now?"
"More than ready, master."
"Good. Both of you can start licking now. Make a good show of it too."
