The Smut Challenge

Prompt: The Teacher's Desk

Pairing: Renzou Shima and Rin Okumura

I stretched out my arms above my head when classes were finally over. When I swore on becoming the strongest exorcist and kicking Satan's ass, I never knew I had to endure high school and cram school, but just because I'm horrible with academics, I am still determined to become a Paladin and defeat Satan.

I gathered up my school books and stuffed it in my school bag. I felt warm arms embrace my waist lovingly, which caused an instant smile to grace my lips.

"Shima…" I whispered his name.

I could feel his hot breath in my ear when he whispered "Have you ever wondered what it was like to have sex on the teacher's desk?" which caused my face to burn.

"S…Shima, someone might see…" I whispered back to him.

"Doesn't that excite you?" He asks.

I looked at the floor, my face still red and pondered on the thought.

The thought of the feeling of the cold wooden desk on my ass as I feel Shima's huge dick ravage my insides, his hot and moist lips all over my skin and the mixture of fear and excitement of someone walking in on us, caused my neither regions to grow hard. I tried hiding it with my hands, but Shima smacked them away.

"I think your answer is a yes." He whispered against my neck, but softly nibbled on my earlobe, causing my erection to ache and me to close my eyes and bite my bottom lip.

"A…ah…Shima…!" I gasped and moaned.

"Do you want to?" He whispered again as he rubbed my erection teasingly.

"A…Ah…yes…please…fuck…me…" I begged to him.

I was never the one to hold out long.

Shima grinned perversely as he turned off the lights and close and lock the door all the way. As he did that, I cleared of Yukio's desk and sat on it, my legs wide open. I panted and moaned as I started rubbing my erection, trying to relieve myself.

It wasn't enough. I needed Shima's cock.

Shima grabbed my hands and tied them together with his necktie. He took off his jacket, making me stand up, so he can spread out his jacket on Yukio's desk. He pushed me back down on the desk, leaned in and captured my lips with his own, sliding his tongue across my bottom lip. I parted my lips, allowing his tongue to cover every inch of my mouth with his saliva. He immediately started unzipping my pants and sliding them off, along with my boxers. I did the same to him, letting his pants and underwear to fall down to his ankles. Shima parted from our kiss for a second. He tilted his head to the other side and kissed me again. I started stroking and rubbing his dick, getting him hard and erect fully as he spread my legs and cheeks apart widely. His penis was slick and lubricated with his own seed. I grabbed the color of his shirt tightly, as Shima pushed himself inside me. I parted from our kiss to gasp for oxygen, clenching my nails against his skin as his dick was pushed deeper inside me.

"Ah Shima!" I screamed in pleasure when his cock rammed into my prostate.

"Ngh….Rin…your ass…is so tight…" Shima groaned.

"S…sorry..."

"No…I love it…"

Once he was all the way in, Shima pulled out of me, the tip of his dick grazing my entrance and slammed himself back inside me roughly, hitting my prostate again. He repeatedly thrusted like that at first, slowly, before gradually getting faster.

"A…ah…Shima…yes…fuck me harder…!" I begged to him again.

He obeyed my request.

With each of his thrusts, I moaned and screamed his name in ecstasy, wrapping my legs on his shoulders, so he could thrust in deeper and held his neck as best I could, since my hands were tied together. I panted loudly to every hard and rough thrust Shima made inside me, my mouth gaped, saliva and tears trickling down from my mouth and eyes in lust.

"A….a…..ah…S...Shima…you have…..good aim…..ah… oh god….yes!" I gasped and moaned to his every thrust.

Shima's warm breath panted in my face as he grinned weakly. His face was covered with sweat.

"Ngh…a…ah Rin…it's your…hot ass…It's….like…it's leading me…to your sweet spot… Oh….fuck… I'm coming!"

"A…ah…please fill me up with your cum….I'm coming too!"

Shima captured my lips again, using one of his hands to stroke my cheek and the other to hold my waist. I bit onto his tongue accidently as I came, my ass clenching tighter onto Shima's cock and my dick cumming all over my face and Shima's jacket afterwards. I parted from his lips to cry out in orgasmic pleasure, "Shima…ah…!"

"Ngh….Rin…AH!"

Rin then, Shima released his seed into my ass, filling it up. I shivered when he pulled out of me, allowing some of his sperm to trickle down my inner thigh. Shima untied my hands from his necktie and rested his head on the crook of my neck, kissing it gently and panting and sweating heavily. I wrapped my arms around his back, hugging him closer to me. I kissed the top of his head. He lifted up his head and chuckled weakly.

"We made a huge mess." He whispered, before licking my cum off my face, causing me to smile and blush.

He licked his lips, smirking at me.

"P...pervert!" I mumbled and panted.

Once we regained our composure, we pulled up our pants and cleaned up. I stared at his jacket as I zipped up my slacks.

"I'm sorry that I messed up your uniform."

He stifled a chuckle and shook his head.

"It's no big deal. I can be washed out easily." He reassured me, causing me to smile warmly at him.

I started reorganizing Yukio's desk. I jumped a bit startled when I felt Shima's hand smack my ass.

"S….Shima you're such a perv!" I yelped out.

"You were amazing Rin."

"I should be telling you that. My ass aches, just so you know."

"Hehehe, my bad." He chuckled.

I shook my head.

"No, it's alright. My ass may hurt, but I feel great." I said, making him chuckle again.

He grabbed my hand, entwining his fingers with mine. I held his hand tightly and checked to make sure everything was back where it was from the beginning, before walking out of the classroom.
