Note: Originally I thought Eren and Mikasa were going to end up together, but after I just discovered this shipping two days ago I thought, 'Hot damn! I can so see this happening.' So this is my first Shingeki no Kyojin fanfiction. Hope you enjoy!

Warning: yaoi (boy x boy), bondage, dirty talk, risk of nosebleeds, and other erotic play. If you don't like then you should and then you will like.

Disclaimer: I do not own Shingeki no Kyojin. Also to note, no humans were eaten by titans in the making of this story. Thank you.

I was exhausted after another hard day of training and cleaning. After I finished cleaning one of the storage rooms, I decided to go to my little home of a dungeon to relax. Then I heard someone call out my name.

"Oi Jaeger! What are you doing?"

'Oh great not him.'

"I-I was just going to relax now that I've finished my duties for the day."

"Oh really? Last time I checked I'm in charge and I tell you when you're finished with your duties."

"Oh come on there's nothing left for me to do."

"Actually I have a special duty for you. I would like you to test something out. Come to my room around 11:00." He slowly approached me and brought me down to his level.

"And don't even think about being late." I could feel him smirk as he walked away. I blushed and quickly walked away. The truth is I've had a secret crush on Corporal Rivaille for quite sometime; however, I'm pretty sure Hanji-San knows about it. I know the feelings will never be mutual and he only sees me as some stupid kid. I couldn't help but blush and wonder what he wanted me to do later. I can only imagine. Though he would never do anything like that, would he?

Later that night...

I was standing outside of Corporal Rivaille's bedroom for a good five minutes to make sure I wouldn't be late. I hesitantly knocked on the door. The door opened.

"Oh good Eren I see you made it here on time. Come in." I walked into his room as he closed the door.

"Please sit on the bed. I have to go get the materials." He went off to his closet. I sat nervously on the bed.

'Materials?! What on earth is he going to do to me?' I thought about his actions earlier. 'Calm down Eren, why are you getting excited. It's not like he's doing to do anything like...that. Is he? No the corporal only sees me as his subordinate.'

Just then Corporal Rivaille returned with a medium sized box. He placed it on the floor and I stared as he pulled out some of its contents: a blindfold, some straps, a paddle, and a whip. There were other things in there, but I wasn't sure what they were. He stood up and looked at me. I gulped, still confused about what would happen.

"Sir might I ask exactly what we are doing." I said.

"Well this is an exercise that will teach you discipline, respect, and control in tough situations."

'Whew and I thought he was going to violate me something. This actually sounds like it'll be rewarding.'

"Are you ready for this Eren?" He asked.

"Yes sir." He then put the blindfold on me, bounded my wrists, and put this gag over my mouth that felt like a plastic ball.

I felt completely cut off from the world; my senses heightened. I felt the bed sink as he moved toward my vulnerable figure. I could feel his gentle touches and his hot breath against my ear. He chuckled.

"Did you honestly think this was a training exercise?" My body stiffened. 'Damn it!' I squirmed as I tried to break free in my confines; however, my attempts were futile.

"There's no use in escaping; however, I will keep my promise of teaching you a lesson before the night is over." I could somehow feel and imagine him smirking over me. He lifted up my bounded wrists and handcuffed them to the headboard. Then I felt his hands roam my entire body. I moaned at his touch.

"Now Eren you must follow every rule I give you; furthermore, break any of these rules and you will be punished. Understand?" I nodded.

"Good. First, you will call me master whenever I address you. Understand?" He removed the gag from my mouth.

"Yes."

"Yes what."

"Y-yes master."

"Good boy. Maybe if you behave well, I'll give you a treat at the end."

He leaned down to kiss me and I instantly returned it. 'My first kiss...and it's with the corporal. So erotic.' He prodded my mouth open with his tongue and I gladly gave him entrance. I moaned as our tongues wrestled and his explored the depths of my mouth.

"Wow you sure aren't resisting much. Have you done this before?" I shook my head. It was my first time, and I had no idea what I was doing. I've never imagined doing anything like this with anyone except the corporal.

"Don't worry I'll teach you well." He unbuttoned my shirt and kissed up and down my torso. I moaned as he marked my body everywhere his gaze reached. He sucked hard on my nipples and nibbled on them. This environment felt so foreign: having someone touch me so intimately. I've always imagined doing this with the corporal, but I never thought it would feel this good.

"Please master, not so rough." I moaned. I moaned louder as he sucked on my sensitive neck. I grunted as he bit hard enough to break the skin. He licked up the blood.

"Alright second rule Eren. You must do everything I say no matter the request."

"Yes master." I admit Corporal Rivaille's control was turning me on.

"Good."

He unbuttoned my pants and slid them down along with my underwear until my lower half was completely bare. I felt relief that my cock was finally released from its confines.

"Alright Eren time to teach you some self control." Then the corporal started to strongly stroke my cock. He removed his hand and gasped as he slowly ran his tongue up my manhood.

"M-master not there! It's sensitive."

He ignored me and sucked roughly on the head and slowly filled his mouth with my cock. I moaned as his head bobbed up and down; the wet sound of his saliva and my precum turning me on even more. I gently tried to thrust into his mouth, but he held my hips down. He stopped for a moment. "Eren, relax and don't try to rush things." I tried to control my urges as he went back to sucking me off. I could feel myself getting closer.

"Master I-I going to-" Then he stopped.

"H-huh." I was confused as to why he had to stop. I was so close.

"Not yet Eren." He said. I felt his body leave the bed as I heard him shuffle through the box. I felt his body next to mine again as I heard an uncapping sound. Then I felt something cold and gel-like rub against my entrance. I shivered at the contact.

"Calm down. It's just something to loosen you up a bit." He said. He decided to put the gag back on me. "I don't want you to get too loud. You don't want everyone to know how much of a slut you are for letting me fuck you like this. Do you?" I shook my head.

I gasped as he pushed one finger inside and then another and started to finger me. He started to scissor me loose and I moaned for more. He added a third finger and a fourth finger as he thrusted harder. Tears lined my eyes and started to slide down my face as his finger abused that one spot that gave me absolute pleasure.

"Wow Eren you must really want it. Your slutty hole is griping and sucking my fingers. How erotic." I moaned and blushed as his words turned me on even more.

"Master, Don't say such things."

"I'll say whatever the fuck I want. You're nothing but my pet." I moaned at the harsh treatment and thrusted against his fingers.

"Do you want more Eren?" I nodded. He removed his fingers.

"Then beg." He took off the gag again.

"M-master please."

"Please what Eren? You'll have to be more specific or I won't know what you're talking about."

"Please...violate me."

"Hmm not what I wanted to hear, but it will do. I was hoping for something a little more vulgar." He said. I wondered what he wanted me to say. I could hear him remove his clothes and I could feel him position himself at my entrance. He slowly pushed himself in.

"Damn you're so fucking tight. You must really love this." Pain instantly shot through my body and tears rolled down my face.

"Ahhh master at this rate my ass is going to break."

"Eren relax or the pain isn't going to go away." I tried to loosen my muscles. I felt my body melt with each thrust as pleasure shot through my body. I could feel myself getting closer again.

"Master I-I'm going to-"

"Not yet Eren! Not unless I say so!"

"B-but I can't hold it in anymore." He stopped. Then I felt this cold, metallic device slide over my cock.

"There." He said.

"What is it?"

"You'll see." He started to pick up his pace as I came closer to finishing.

"Master I'm going to-" Then nothing came out. He removed my blindfold and I could see the strange situation I was in.

"W-What?" Then Corporal Rivaille started to stroke my swollen cock that couldn't release.

"See Eren. This is called a cock ring. It prevents you from orgasming." It hurt. I wanted to come so bad and the stroking only made it worse.

"You need to learn more self-control. When I'm ready for you to come, I'll take it off."

"B-but-"

"No buts! You promised to obey your master didn't you!"

I looked away and blushed. "Yes."

"Yes what! And look at me when I'm speaking to you!" I yelped as he gave a hard thrust.

"Yes master." I said as I looked into his eyes.

"Good." He started to thrust into me once more and I moaned louder and louder. My cock felt like it was ready to burst as I came over and over again.

"Eren I'm going to come." I strained against my restraints to touch him. He smirked and finally decided to take off the handcuffs and remove the black tape from my wrists. I wrapped my arms around his neck and brought him down into a deep kiss. Our lips moved hungrily against each other as I felt his thrusts become more sporadic. My cock wept some precum but full pleasure was still denied.

"Master..please let me cum. I can't take it anymore." I sobbed and begged.

"Alright Eren you've been a good boy so I'll reward you." I could feel the pleasure building up again as he humped me into the mattress. He finally removed the ring and stopped thrusting. I whined at the loss when I was so close.

"On your hands and knees, Eren." He commanded. I obeyed and managed to keep the corporal inside me as I did this. I moaned as he gripped my ass and thrusted into me again.

"Eren you are mine! You got that!"

"Ow yes! Yes master I belong to you an no one else!" I yelled. He smacked my ass hard.

"Good."

His hand reached down to stroke my cock quickly.

"Ahhhh!"

"Come for me Eren." He bit my shoulder harshly, and I moaned loudly as my back arched and I came hard onto his hand and the sheets. Everything went white and I felt in total ecstasy as more orgasm finally came and consumed my entire body. Corporal Rivaille soon came inside me and filled my insides to the brim. He slowly pulled out and my body shook, instantly missing his presence. We laid on the bed together in silence for what felt like an eternity.

'Is he going to say something? Is he going to leave?'

"Alright, what's bothering you?"

"N-nothing." I gasped as he suddenly pulled me against him. He just stared at me and I couldn't help but feel pressured to say what was on my mind.

"I-I was j-just wondering u-umm what does t-this make us now?"

He grabbed the back of my head and kissed my forehead.

"Damned brat." He said with his lips still on my head.

"I already told you, you're mine now. Now go to bed."

He held me against him as we both drifted off to sleep. As my eyes closed, I couldn't help but feel even more confused about my relationship with corporal.
