Suggest moving to the bedroom

“How about we take things to the bedroom?” you suggest.

“Sounds good to me,” Katherine agrees. “Do you want to tie me to the bed, master?” she grins.

“We’ll see…” you say, freeing her from the chair.

She rubs her arms and legs as they are freed, then places her hand on your crotch. “I can’t wait to give this guy a ride…” she quips.

Even though you enjoy her spunk, you give her a stern warning. “Only touch when I give you permission to touch, girl.”

Katherine quickly retracts her hand and plays it off apologetically. “I’m sorry, Master.”

You roll your eyes and sigh.

Rather than assert your dominance, you lead Katherine to your room. Fortunately, you managed to get it relatively tidy before everyone showed up, so no need to worry about dirty laundry undermining your authority. As you pass the bathroom, you feel a tug on your arm and glance back at Sabrina, signaling for your attention. You call out to Katherine, “Make yourself comfortable, I’m going to freshen up.”

“OK, John... don’t keep me waiting…” Katherine sings back.

“That’s ‘Master’ John to you!” you reply teasingly.

“Yes, master!” Katherine replies.

You lead Sabrina back into the bathroom and close the door behind you.

“Everything going well?” you ask her.

“No!” she answers with a hiss. “You’re not supposed to get her to like it! You’re supposed to be embarrassing her!”

“That wasn’t part of the agreement,” you remind her. “My job was simply to get her to do sex acts for you to get on video.”

“Yeah, but she wasn’t supposed to enjoy it!” Sabrina pouts.

“Jealous?” you smirk. She is adorable when she’s pouty. “Need me to give you a quick rub down before I return to your sister?” you tease.

“What? No!” Sabrina replies quickly. Her cheeks are bright red now. She gives you a double take, as if she is contemplating the offer, but shakes her head. “Look, just get her to do something embarrassing and we can get our money.”

“Sure, sure, I’ve got it covered,” you assure her with confidence. “I’ll have her as red faced as you are now!”

“I am not…” Sabrina glances in the mirror then looks away, covering her cheeks. You can’t help but grin over her embarrassment.

“I’ll be sure to save some for you later,” you offer.

Sabrina shakes her head and sighs, pretending to be checking her phone so she doesn’t have to look you in the eyes. “Just finish with my damn sister already!” she grumbles.

You take a quick rinse in the sink and head back to the bedroom. There, you find Katherine splayed on your bed, eagerly anticipating your arrival. It is like walking into a porn spread with Katherine laid back, legs parted, fingering her pussy as she eyes the doorway.

“I was starting to get cold, master,” she explains. “Maybe you can warm me up with your hot, meaty cock?”

You only imagined things like this would happen in a porn movie, but here you are having a porn moment in your very own apartment! You walk into the room and Katherine eagerly sits up. She has her camera phone out and hands it to you. “I think getting shots from your point of view will be best for the video,” she tells you.

Now you have both sisters telling you what to do. You could either stick with Sabrina’s plan and put Katherine in an embarrassing situation, or you can go with Katherine and record fucking her brains out.
