Chapter Text
Terzo wasn’t a jealous or possessive man. In fact, he was very secure and comfortable in his relationship. Sure, in the past, he’d been known to have a jealous streak, but things were different now! It was different with you. He never paid any mind whenever other siblings of sin happened to put a hand on your shoulder while you talked, or if the ghouls decided to invite you to their nightly cuddle-puddle. But something had snapped in him today, and he suddenly felt the very familiar sensation of jealousy burning hot in his veins.
When he saw the way that you smiled at Copia- his smile, the one that you only flashed him in the early mornings while in bed together or that settled on your lips after one of his stupid jokes- that was a tipping point. The moment his younger brother had walked down the hall, Terzo had a bruising grip on your wrist as he dragged you towards his bedroom.
Now, his hips slam viciously against your ass as he pants above you. You’re on your knees at the edge of the bed, back arched as Terzo’s hand remains firmly on the back of your head, pressing your face down onto the mattress. Your arms are sprawled out in front of you, desperately clutching at the sheets.
“You really didn’t think I would see the way you looked at him? Oh, piccolo, that look is for me and only me.” He leans down with his words, chest pressing to your back as he snaps his hips into yours.
“‘M sorry,” is all you’re able to get out between your face in the mattress and his brutal pace.
“You understand that you’re mine, sí? Not my fratello stupido, not anyone’s. Mine.”
“Yes, Papa,” you whimper, reaching a hand back to try and grab at the one he rested on your hip.
Terzo laughs darkly, allowing you the relief of holding him despite his initial instinct to punish you, and he tugs a tug to your hair. Your head jolts up with his yank, a gasp escaping your lips, and your eyes screwing shut.
“I want to hear you say it, amore mío. Tell me who you belong to.”
“You! I- Fuck, I belong to you, Papa. ‘M all yours, Terzo, I promise,” you sob as he releases his hold on your hair, dropping his hand to grab at your other hip as his hips stutter into yours.
“That’s a buono cucciolo for your Papa,” he groaned out, the rolling pace of his hips growing inconsistent. “And now you’re going to be a buono ragazzo and take my cum, understand?”
Words are lost to you, so you’re only able to nod your head enthusiastically as his brutal pace continues. It was rough, somewhat inconsiderate, and almost hurt. But it hurt so good that you wanted more of it.
The grip Terzo had on you tightened, so much so that you were certain you would be left with bruises the next morning, and he pushed himself into you as deep as he could as his cock pulsed and shot rope after rope of cum. Your mouth opens in a loud, repetitive cry of his name as the feeling of his hot release pumping inside you sends you over your own peak.
Terzo’s quick to move to lie down beside you, legs shaking from the exertion, and he curls an arm around your waist and pulls you so that your face rests on his chest. His spend slowly leaks out of your twitching hole, but both of you seem to mutually agree that’s a problem for later. The two of you lay there, panting for a few moments before you raise your gaze up to Terzo’s face.
“You know I love you, right?” You mumble as you press a gentle kiss to his collarbone.
“I know. I apologize for getting so jealous.” The man offers you a wide grin as he meets your gaze before leaning down to give you a sweet kiss. “And I love you as well, cuore mío.”
