Something is definitely bothering Stacey (alright people, sappy stuff is over, let's get back to the smut)

You've been in a relationship with Stacey for 2 years now, and you can tell that there's something that's worrying her. It's definitely not about you hogging the marker, she made that pretty clear. After separating from your hug she gives you an almost genuine smile.

“Stacey.” you said in a firm tone. This makes her drop her smile.

“You are going to tell me right now what's going on with you.” this time instead of a firm tone, came out a commanding voice. One that you didn't knew you even had. But currently you are feeling like your brain isn't in charge. Since the start of this conversation you have this sensation deep inside of you, like your gut has picked up something you haven't.

“Ooo, I think I like this bossy side of you.” she says playfully.

You simply give her a serious stare, implying that you are not kidding around.

She finally comes clean with a sour face “Alright fine. I've been feeling guilty because I think I hurt when you saw me being fucked by Olivia.”

Oh no, that's truly a touchy subject for you. So this is what your gut was trying to warn you about. Even if it was the influence of the marker, the image of your girlfriend being fucked right in front of you, by another woman with a dick, making ecstasy faces, it's not something you forget easily. You were trying to avoid bringing it to Stacey's attention since it would be putting more guilt on her. And frankly, you didn't want to talk about it either, to not think in how it got to you. But now that she has brought it up, the weight of all the emotions and sensations you've been trying to get in control to not lash out, are flooding like an endless river. Anger, betrayal, sadness, impotence, lust, hatred.

How are you going to cope with all this? You have not idea, but in this moment, it's not your brain that is in the driver seat, but rather the instincts that have been screaming inside of you to be released.

Your girlfriend, holding her tears back, has embarked herself in a speech about being sorry, which your hearing blocked out for being to out of yourself. You can see that the same concern you had for her before, it's redirected to you. Despite being her the one that was ravaged by her best friend, she is worried about how it has affected you. It's very sweet of her.

That's the last rational thought you have, and just after that, you are pushing Stacey back in the couch, landing in a sitting position again.

Stacey is too surprised at first to do anything. Seizing the opportunity you use one hand to lay her down in the couch and open her legs, while the other is busy stroking your dick. Doesn't take too much to get you to full mast with the sight of your naked defenseless girlfriend.

She seems to recover from the shock a little “Finn wait-AHHHHH…” Her sentence is cut off by you ramming your dick inside her cunt in a missionary position. Your sudden intrusion is welcome with a wet sensation. It seems that all it took to get her going was that small show of dominance.

Taking advantage of your momentum, you keep thrusting in and out of her with incredible speed and strength while Stacey moans incontrolably. Her **** to this sudden outburst slowly fades away as she buck her hips trying to match your rhythm, but failing in the process. “Ahh, yes, yes, keep going.” She's got the spirit, but not the energy you currently possess.

The couch is large and wide enough for this sex session not to be uncomfortable for you or Stacey, so you decide to take it a step forward. You grab one of Stacey's leg and lift it over your shoulder,giving more maneuverability to thrust full speed “AHHH, just like that. Oh my god it feels sooo gooood.” her eyes are alternating between opened and closed.

It does feels very good, but you need to last longer, you don't plan on cumming before her. You change strategies and instead of going for speed you now go for depth. You reposition yourself looking for a better angle and as soon you get it, you give a balls deep thrust.

“Ahhhh, s-sooo fuuull… Don't s-stop …Go d-deeper…” she's speaking between pants right now. You keep pumping with all your strength, reaching as deep as you can inside of her.

You start to feel her walls clenching around your dick, indicating an impending orgasm. “I'm… I'm… c-cumming!” her back arches as a orgasm washes over her. Her body gets stiff, the leg over your shoulder presses tightly against your back looking for something to hang on and her eyes are closed.

When the pleasure recedes her body returns being limp. She open her eyes looking at you, searching for answers as to why this happened. She desperately tries to say something when you say the next words:

“I'm not done with you.” you take a sitting position and doing most of the heavy work you carry Stacey so she is on your lap facing you.

With her breath partially recovered and knowing what's coming next she says between gasps “Hang… hang on… I am… still very sensitive.”

Once again you ignore her words and you penetrate her soaking pussy. A shiver runs up her entire body.

This time she is even more hesitant than before. She tries to pull out but you stop her by saying “You are mine Stacey.” You grab her by her wrist, using her arms as a leverage to bury her deep in your dick.

“Ahhhhh!” she screamed forgetting her sensitive pussy and being overcome by a new wave of pleasure.

“You are my bitch Stacey. Mine! And I'm going to show you and your body that!” you said using your newfound commanding tone. “Now say it!”

“I'm yours! I'm your bitch! I'm your whore! I was very naughty by laying with another woman and I deserve this brutal and delicious fucking that master is giving me!” she got more into this that you were expecting, but you are definitely not complaining and roll on with it.

You thrust with more energy causing Stacey to shoot her head up “You like being fucked like a whore?!”

“I l-love it! I love it when master fucks me like the whore I am! ”

She is on the edge of another orgasm and so do you.

“I'm gonna cum deep inside of you, you hear me bitch!”

“Yes! Please do! I'm also cumming! I'm…I'm… CUMMING!!!!”

With a final thrust you plunge yourself as deep as you can, releasing all your seed inside of her. Meanwhile Stacey is enjoying the bliss of her second orgasm in less than 10 minutes. Her eyes rolling over the back of her skull and her body twitching uncontrollably. Finally she slumps over you like a ragdoll, head over your shoulder, breathing heavily like she ran a marathon. You both stayed glued in place for a moment, your dick still inside of her, and your lap full of Stacey's juices and your own cum now dripping from her snatch.

With your thoughts now a bit clearer you whisper in her ear in a calm voice “You don't need to feel guilty. I just proved to you that I own you, and what Olivia did to you can't erase that. And don't you dare to cry again.”

A muffled voice said replied “I'm not crying, I'm smiling.”

You have no doubt of that, but you definitely feel a moisture sensation on your shoulders falling over your back.
