How far could I go with you? (Mafia! Frank x reader)

Love

'I'm going to do something a bit different today.' I watched as Stephie swung back and forth. She was held up by her arms which were tied up and hooked to the ceiling. I fiddled with my new toy, grinning as she screamed at the sight of it. 'This is called a Urumi. It's like a whip but instead of your usual leather, it's made of a thin, sharp metal. I could cut my finger by just tracing it.' I lifted the whip past my shoulder and struck it straight into her bare torso. She screamed, tears quickly pouring out of her eyes as I repeated the action while singing loudly. 'Hey pretty baby with your high heels on!' I brought the whip down straight on her tit, some of the nipple even being sliced off. I continued to sing loudly over her pained screams and shrills of agony. 'Just kiss me baby and tell me twice that you're the one for me! The way you make me feel!' I began singing the chorus to Michael Jacksons "The Way You Make Me Feel" as Stephie thrashed her legless body around, hoping to somehow break off from her restraints. Blood was pouring from between her open wounds as I relentlessly brought my sharp whip down again onto her hips, cutting through her flesh. 'You knock me off of my feet now baby! My lonely days are gone!' Stephie slipped out of her cuffs, the sweat probably helping her. She thudded onto the ground, splashing in the pool of her own blood that was beneath her. Her chin knocked against the concrete. She let out a sigh of relief before hearing me crack my whip against the cold ground. She suddenly flinched as the sound echoed through the room before fading back into silence. Stephie was trying desperately not to make any sound and for a few seconds she was succeeding until I lifted the whip and began gently dragging it across her back. 'Your skin looks so soft...I wonder how thin it is.'
Slash!

I placed Stephies eyeball onto the bedside draw, along with her two kneecaps. Frank stared at me in shock as I laid all my mementoes beside him and quickly asked who's they were. 'You've been out for about two weeks and every three days or so I'd take her down into Gerards chamber and I remove a part of her body. First it was her kneecaps, then her tooth and legs then finally I took her eye. The rest of those days she spent healing. I kept her alive just so you could watch me kill her.' Frank smiled gently at my words, obviously touched by how considerate I was being. 'I...don't feel without you.' I admitted. 'I didn't feel any remorse when I was mutilating her...' I crawled onto Franks lap, feeling like I had just reclaimed my throne. 'I've changed...'
'You have...this violence has raped your common sense.' Frank leaned forward, gently nuzzling his nose into the crook of my neck. '(Y/n), are you happy with this life? With killing people?'
'Actually...I don't care. I...I do everything I do for you. I love you so much it hurts. I love your devotion, your looks, your wit, your skills...I love your taste in music, how you focus so hard in meeting, how you tap your fingers...I want to marry you and have your child. I want to grow old with you so when we're done with life we can kill ourselves together so neither of us have to live without the other. I wanna live in a cute little apartment with you and wake you up with head in the morning.'
'I love you, (Y/n). I love you so much I'd kill myself for you.'
