Swallow my Fingers

Part one

I've never wrote a fanfic based off a show so please bare with me! Also somethings may not add up to the anime.

Third person

"Fingering? Sure, you should've showed me this way earlier!" Itadori called as if it was supposedly a new technique. "I've been so pent up in this small head." Sukuna said seeming annoyed. "For your information my heads quite big which means I'm smart!" Itadori yelled also adding "Also you look just like me..." pointing and laughing at him.
"Stop talking and climb up here already." He scoffed.
The boy complied and stood in front of the spirit smiling "are you gonna tell me where a finger is?" He asked Sukuna. "If it's called fingering you mu-" Suddenly his voice faded. "I told you to shut the hell up." The cursed spirit whispered. "Mmm!" Yuji pouted putting his hands on his hips.

Sukunas POV

Ever since Itadori swallowed my finger It's felt like I've been in rut. I can't exactly take over his body completely and relieve my self through killing or anything else. "Turn around." I demanded. If I had a choice I'd force a woman underneath me and enjoy their terror. "Futile clothing." I sighed easily removing them only to be left with naked Itadori. "MM!" He mumbled covering as much of himself as he could with his two arms.
"This is boring..." I said swaying my hand granting him speech. I yanked him closer to me "W-Why do I have to BE~" he yelled as I stuck a finger inside of him "Stop tightening yourself!" I called getting restless stuffing two more in. "S-Sukuna! This isn't a t-technique!" He groaned grabbing my wrists.
This idiot really thinks I'd take time and show him a new technique all because I showed him a little kindness. Thrusting my three fingers up and down. "Nugh!" He moaned tightly holding my wrist. "Fuck.." I whispered knowing I got turned on from his moans.

Yuji itadori POV

"Naahn!" I moaned as he took out his sharp fingers. Suddenly setting me on his lap "I don't wanna hear you." He said. then without warning he thrusted into me "AGH!" I Grunted. I looked up and saw Sukuna with a big smirk on his face "what's wrong itadori? Can't you handle a big dick?" Sukuna laughed thrusting deeper into me. After he said that I was determined do it harder. "Shut your mouth Sukuna!" I said slamming together "GAH!" I shuddered not realizing how it'd affect me. My body shook uncontrollably "FUAA!" I moaned. My vision went hazy as he came inside me. when I was able to see clearly again I was holding onto the cursed spirit Sukuna and couldn't let go.
