Enjoy the New Addition

That night, the three of you showered together, finished off a few more bottles of wine, and eventually made your way to bed well past midnight. After sleeping in the next day, Lucia made the three of you breakfast, and you all eased into the day. Around noon, Rosa left to start packing her things so that she could move from her small apartment to your home.

A few weeks later, Rosa was all moved in, and had ended the lease on her apartment. She was officially committed to her new lifestyle, much to your delight. Once she moved in with you and Lucia, you decided that it was time to formalize some house rules for the sisters. After a couple of revisions, you presented the sisters with a couple of simple expectations:

(1) Both women would obey your commands without hesitation. No boundaries, no limits.

(2) Except for their respective collars, both women were required to be completely naked while in the house, but were free to dress as they pleased while outside or away from the house (unless instructed otherwise by you). The only exceptions were that they could wear an apron while cooking or a french maid uniform while cleaning if they chose to.

(3) Both women would be equally submissive to you unless you specified otherwise.

(4) Both women would keep their new status just between the three of you unless given permission to talk about it with others.

(5) You would be free to pursue sex and intimacy with other people, but the sisters would only be allowed intimacy with each other and yourself unless instructed otherwise.

Unsurprisingly, both women informally agreed to their new rules quite readily. However, you wanted each of them to both verbally and physically commit themselves to you according to these requirements. You explained the ceremony that you had in mind, and confirmed with the sisters that they did not have any questions. To set the scene, you lit some candles, placed them in a semi-circle in front of you, removed your clothes, and turned off the lights to set the atmosphere. Since Lucia already had her collar, you had her go first. You figured this would honor her status as your wife and would serve as a good example for Rosa.

Completely naked according to your orders, your wife knelt before you in the middle of the candles as Rosa looked on from the side, also on her knees. The candle light danced across her soft skin and dark hair, flickering in her eyes as Lucia met your gaze.

"When you are ready." You instructed her.

"John," She began without hesitation. "I love you with all of my heart, and will do anything that I can to make you happy, just as I vowed on our wedding day. I commit to you now, just as I did before, both my heart and my body. I will be yours to have, to command, and to use. I will become an instrument for your pleasure, and will seek joy in your fulfillment. Please accept me as your slut, and show me my place."

With that, Lucia opened her mouth and waited for you to prove her commitment. Following the same ceremony as before you walked up to her and grabbed both sides of her head before shoving your now-hard cock down her throat. This time, you didn't have to worry about pushing past her throat barrier given how much practice she's had at deepthroating you. After savoring the feeling of her tight throat around your dick, you begin to shove her head up and down your member, from the very base to just below the head.

Like a dutiful wife, Lucia kept her hands resting on her thighs as you roughly used her mouth and throat. This time, you didn't pause to give her breathing breaks, you just kept shoving her up and down, enjoying the gawking sound she made each time you bottomed out. After a bit, you instructed her to take over, putting your hands behind your back. Without missing a beat, Lucia began to fuck her own mouth on your dick, keeping the same intense pace that you had before.

You let out a moan of approval as you felt your balls slap wetly against her saliva-coated chin. As streaks of mascara ran down her face, you relished the sight of your submissive wife accompanied by the sounds of her gagging herself on your cock while her sister looked on just feet away.
