Dark and slutty indeed

While Lucia was putting herself together, you and Rosa talked idly while finishing your breakfast, debriefing her experience as the house sex object.

"To be honest, it was truly amazing." She said reflectively. "When I've been submissive before, its only been to one person, so being controlled by two people was a totally different experience."

"Different in what way?" You prodded.

"I don't know, I think that having multiple people with that power over you just forces you go to a deeper place inside. Like a deeper connection to the idea of being just an object. Mentally, I didn't know I could go that far until I didn't have a choice! Physically too, I didn't know I could go that long without air until your dick was lodged in my throat. To accept that level of objectification was...intense!"

"So you think you'd like to go there again?"

"Yeah, I think I really do!" Rosa said, nodding her head excitedly. She didn't have to think about this one!

"Good to know! I think your sister and I both loved having you as a toy, so we can easily make that happen again." You said with a smile. You then turned the conversation to your absent wife. "And speaking of your sister, I was thinking of taking a more indirect approach at first."

"Aww," Rosa pouted. "You mean I don't get to use the slut this time?" She gave you her best puppy dog eyes, making you chuckle.

"Don't worry, you'll get your chance for that too, but since she's my wife, I thought it would be better to cuck her first and really **** her to feel the loss of status." You went on to explain your ideas

At this point, Lucia returned to the dining room, and it was clear that she made a serious effort to met Rosa's expectations. Her makeup was done perfectly, with dusky eye shadow, black mascara, and black lipstick. Her hair was braided in a ponytail, and she had on a pair of medium-sized gold hoop earrings. Aside from that, the only things that she was wearing were her collar and a fishnet bodysuit with a cutout providing easy access to both of her lower holes. Dark and slutty was the goal, and damn if she didn't hit a home run!

"Good!" Rosa said, "Our little bitch is finally fit to serve us! Stand there and let me look at you." Lucia spread her legs and crossed her arms behind her waist, causing her chest to push out. Rosa walked around Lucia, grabbing a handful of ass here, twisting a nipple there, and generally making her sister feel like something being appraised at an auction. Meanwhile you excused yourself and went to the bedroom to grab a few things.

Upon your return, you found that Rosa had progressed her inspection, having Lucia bent at a 90 degree angle, facing away from the door while Rosa sawed a finger in and out of her asshole.

"Perfect timing!" You said as you pulled a buttplug out of the bag you brought with you and held it up to Rosa's mouth. "Mind giving it a first pass?"

Rosa flashed a dirty grin at you, holding eye contact with you as she slowly took the buttplug into her mouth, swirled her tongue around it, and dragging her bottom lip across it on the way out. You gave her a wink and positioned the plug at Lucia's asshole, now having been vacated by Rosa's finger. Lucia's dark rosebud twitched as you rested the tip against it. After a brief pause, you forcefully pushed the buttplug fully into her waiting tunnel. Lucia grunted instinctively in discomfort, but didn't protest, having committed herself to being the best houseslut that she could be. Her anus contracted reflexively as it adjusted to the intrusion, causing the red jewel on the plug to shimmer in the light.

With that done, you set the bag down for later and started step 1 of your plan.
