Author's note: Apparently Yourweirdgal really liked the unknown x reader, so here's another one for you! These are pretty fun to write, I just have to make sure not to describe certain things😝. I'm also not exactly sure who to do one with out using a blindfold Lolol

Y/N's POV

I rolled over in bed. Insomnia plagued me. I threw my blankets off, reveling my tank top and underwear that I usually slept in. I threw my arm over my eyes and sighed.
I gasped as a pair of cold hands touched my hips. I went to kick them, and take my arm off my eyes to see them, but they held my arm in place.
"Shhhh... It's ok, baby." I stopped struggling because I recognized the voice. It was definitely the voice of someone in my class.
"Who are you??" I asked quickly. I felt the man sit on my abdomen.
"You don't have to know yet. Just hush, and I'll make you feel good." I gasped as the boy's lips suddenly made contact with my neck.
"W-Wait!" I exclaimed, as he bit down. I felt a tiny drop of either blood or saliva trail down my neck.
"I'm going to remove your arm, but you better keep your eyes closed." I gulped and nodded.
He did just as he said. I felt his skin brush over mine as he slipped what could only be described as a blindfold over my eyes. As he went for my neck again, I felt his hair brush against my face. It was spiky. I smirked as I came to understand who was doing all of this to me.
"W-What if I know who you are?" I asked, parting my lips slightly.
"Guess." The boy growled. That sealed it for me.
"Are you, Bakugo?" The man laughed.
"Funny. I'm not Bakugo." My mischievous smirk turned into a look of confusion, but it was immediately relieved at the boy bit down on my neck again. "If you need something to scream out, just call me daddy." The boy whispered, pressing his lips roughly against mine.
I twitched and squirmed under his hands. I felt his left one trace my sides, going down in between my leg. His finger traced the edge of my panties before pushing them aside, and playing with my sensitive spot. His finger plunged deep within, and I couldn't hold back a moan.
"Aaah!~ Daddy..." I moaned, biting my lip hard. The boy chuckled.
"Do my fingers feel good, baby?" He asked, as his thumb started rubbing my clit. I nodded quickly, running my fingers through his hair. Upon doing that, I really felt his hair. This hair wasn't Bakugo's, but I couldn't tell exactly who's hair it was. I'd definitely run my hands through their hair before.
As soon as those thoughts passed through my head, my mind was taken back to the situation at hand. The man removed his fingers and I panted from the lack of contact. The boy chuckled and I heard the rustling of clothing.
I felt my walls stretch as something was shoved deep inside of me.
"You're so beautiful, Y/N. I love you." He mumbled, as he started to slowly rock his hips back and forth. I was a moaning mess under his control.
"Nnnngh... Daddy~..." He leaned back and kissed me. I could feel his smirk.
"Y/N, you feel so good..." The man groaned, going a bit faster.
That's when I noticed a small ball building in my core. The knot only grew bigger and bigger. I wanted to moan louder, but we were in the dorms, and everyone would hear. The knot in my stomach grew rapidly as the man started to roll my clit in his fingers.
"Daddy, I-..." I was cut off by my own moan. "I-I'm close..." The swore, pushing deeper inside of me than he had this entire exchange.
"Me too." He grumbled, going very quickly. He rammed into a certain spot deep inside of me that made the knot explode like a bomb had gone off inside of me. The man kissed me to stifle our moans, and I felt his seed paint the inside of me. My back was arched and my head was pressed into my pillow.
The man pulled out of me and laid next to me. After I finished taking deep breathes, I turned my head towards the man.
"Can I see who you are now?" The man hesitated, but I felt my blindfold being taken off.
I slowly blinked open my eyes to come face to face with red spiky hair and sharp teeth.
"E-Eijiro!" I exclaimed, blushing hard. He also had a bright red blush on his cheeks. He pressed his lips to mine, and I kissed him back.
