Reverse Harem of Y/N +18!!

I don't understand

Thank you all for being patient with me while I take a while I work and slowly publish. I'm going to do my best to keep putting chapters out regularly. 

As I explain my dream to Touya and Keigo, I myself have a hard time believing it was a dream but I never left the bed so how. All of us are filled with more and more questions than answers.  Sighing we all decide to drop it for now, but it never leaves my mind. When my whole world is shattered in an instant I hear a voice inside my head that not my own laughing at me. "Don't think you can challenge me mortal and not expect me to come and show you one way or another how I can play with you." He chuckles loudly his voice echoing in my head making it to where there isn't any room for other thoughts. I'm pulled from my thoughts just when about to come back with some bratty response when I feel Touya's hand on my lower back radiating heat. 
"Princess, come on focus." he whispers in my ear.  I lean back into him feeling his chest against my back sighing softly I look up at him.   "You here with us?" he chuckles running his hand up from my shoulder to my face.  I nod all while Sukuna is laughing in my head teasing me about how worried the two men are concerned about me.  "Awe the burnt bitch is worried about you." he laughs harder causing you to shift uncomfortably.  Keigo runs back out to us saying he has to go to work flying out the window, when Touya's phone goes off  it's toga saying it's an emergency. Hanging up the phone he leans down giving me a kiss wrapping his hand around my throat lightly making my heart flutter for a moment when he finally pulls away kissing the top of my head "I'll be home later princess. Behave." he says winking at me and giving a smirk as the door shuts behind him. Sukuna chuckles "PrInCeSs huh? well mortal now that we are alone it's time for our little play time." he says laughing "Shut up Sukuna. it's so hard to think." "you wont need to think once I have you." Walking to the bathroom I run the bath putting in rose petals with some lavender bath salts to help me relax hopefully. I go to the bedroom grabbing a pair of shorts and my favorite shirt. Stripping out of my clothes as I walk back into the bathroom giving myself a once over in the mirror seeing the bruise around my throat and wrist and on my hip. Sighing I step into the bathtub sinking into the water as the warmth comforts my broken body.  "You look so peaceful." Opening my eyes I turn quickly to the left expecting to see Sukuna. ~It really sounded like he was beside me.~  I feel hands tangle in my hair playing with it.  I close my eyes just enjoying the feeling. "Look at me Y/n" Sukuna's voice booms causing me to jolt upright looking around only to find that yet again we are in his domain.
