A/N) So thanks to everyone who has decided to fav and follow this! You guys are really awesome and make me feel a lot better about myself while I write this! I seriously might love writing this way too much! So yeah, the beginning is the continuation of the last chapter, where things are going to get a little more kinky! We also will do a little focus on the aftercare which is important in any dom/sub or even pet relationships. Then we go on to gender identity and transexuality. I will probably always give warning in each chapter just to make sure people know exactly what they are getting into. Just as a precautionary kind of thing! I don't want to set anyone's trigger or anything.

So enjoy. I don't own AoT/SnK. I'm just a fanboy with an idea!

Have you ever been so deep in pleasure, that you can't even breathe because it feels so good? That's where Eren was at the moment. He was on his knees, with a speader bar holding his quivering thighs apart, his face was in the pillow, drooling on it, and he had a butt plug shoved in his ass, buzzing merrily against his prostate. His body was trembling uncontrollably. His arms were still cuffed behind his back, and the metal was rubbing into his wrists, the marks would be there for a few days. The best part for the little masochist, was that Rivaille had switched to a paddle. He aimed right in the middle of Eren's backside, which forced the toy in deeper with each smack, before his inner muscles pushed it back out. Eren screamed his pleasure out into the pillow. It hurt, and it sparked his body to life. It was amazing every time that pain rippled through his being. It stung, but also came with a wave of absolute rapture. Rivaille was amazing at this. The cock ring had already held off an orgasm twice. His poor cock was flushed red, and dripping, maybe too much precum to be healthy.

"Your being too quiet Eren. I haven't gagged you, yet." Rivaille purred devilishly.

Eren shuddered at the tone of voice, and the whispered threat. It was too much! One last smack onto his bright red ass, and Eren lost it. He came completely undone, and he screamed his release into the pillow. His whole body trembled, and tears of pure arousal cascaded down his cheeks. It was the most amazing orgasm of his whole life. As his body relaxed, he began to whimper in disappointment that the absolute high he had found was beginning to go away. Especially, when Rivaille pulled out the vibrating plug from his body. As he came down his high, Rivaille quickly began to undo everything. He pushed on the safety latches of the handcuffs, and Eren's now limp arms slid down onto the bed. He worked the spreader bar off as well. He reached between the boys legs, and unlatched the cock ring, and felt Eren shudder as relief flooded through his body. He pushed the small of Eren's back, and encouraged him to lay his body down, which he did without protest. Rivaille put the stuff down on the table, and found some soothing cream in Eren's bag of toys. He went to work, rubbing the cream all over the red marks littering the boy's entire back. He even rubbed some cream where the spreader was, and on his wrists.

"Thank you, master." Eren croaked out weakly.

"Shhh," Rivaille cooed "no more master, okay? I'm Rivaille, and you're Eren, okay? I'm going to get you some water."

Rivaille had full intentions to get Eren water, but he had something to take care of first. He couldn't give Eren proper after care with a raging boner in his pants. Once secured into the bathroom, he freed his rock hard erection from his already tight leather pants. He grabbed it in a firm grip, and stroked the already wet hardness in quick rapid strokes. He bit down on his bottom lip, and focused to breathe through his nose as he got off. He felt a little embarrassed for losing control like this. Jobs like this, usually never got him hot and bothered, but something about this boy, and his beautiful eyes, and gorgeous moans sent heat right into his groin. He braced his unoccupied hand on the bathroom wall, as he continued to stroke firm and fast. His poor bottom lip was being abused by his teeth. With one final stroke, he came, catching it mostly in his hand. He finally allowed himself to pant through his mouth, as he washed his hand off, and fixed his appearance. Then he grabbed a cup, and filled it with water for Eren.

When he returned to the room, Eren hadn't budged an inch. Rivaille walked over, helped Eren onto his side, and handed him the cup. The boy drank like he had been in a desert for years. It wasn't surprising, considering all the erotic noises that mouth made, he was bound to be a little thirsty. Also, all the sweat that covered his body, probably dehydrated him too. Rivaille sat by his head, and ran his fingers through the messy chocolate colored hair.

"You alright?" He asked Eren.

"More than alright. I'm absolutely fucking perfect." Eren answered.

Rivaille gave a rare smile "Great. Once you feel up to it, you can take me to my car."

"Oh shit! Of course!" Eren went to sit up.

Rivaille was going to stop him, but Eren was up and grabbing clothes before he could react. He was baffled. Eren wasn't responding to all the marks that littered his body. Not even a wince of pain crossed his features. Rivaille quirked a brow. Something about this kid was amazing. "This goes against my code brat, but how old are you?" He had to ask.

"Oh, I have to talk to you!" Eren looked at Rivaille, and had a look of panic

"Sure." Rivaille sat down.

"You know my name. Obviously, you must have heard of the esteemed Dr Yeager, or of Yeager fashion?" Rivaille nodded "That's my parents. You could fucking ruin my family if you don't keep your mouth shut! I don't care how much you want, but I will buy your silence!"

"Little heir to the fortune has a dark side. Your secret is safe with me. I don't need fucking hush money. I actually strip and shit because I want to, not because I have too."

"Oh, are you sure? Because if you wanted to...I would like to do this again." Eren blushed.

Rivaille couldn't help but think how adorable this kid was. But he reeled those thoughts in. He never fucked a submissive, and wouldn't start now. Attachments to clients was against his code. "Yeah, come see me at the club whenever you want to do this again."

Those gorgeous aquamarine eyes lit up, and sparkled in happiness "Really? You will be discreet, and see me again?"

Rivaille sighed, and had a bored look on his face "Yeah sure, whatever brat."

Eren smiled "I'm twenty five!"

Levi scoffed "Yeah. You really are a brat."

"Woah Armin, what's with the dress?" Eren asked his friend the next morning when the door opened. They decided to meet up at Armin's for lunch. Apparently, they both had much to talk about.

"I have fake tits on too, and you ask about the dress?" Armin asked "and what about you those bruises on your wrist? They look nasty painful."

"No, they feel amazing. You should see my back, and thighs. But enough about me, I thought the dressing up thing was a kink."

Nothing else was said until they both were sitting at the kitchen table, and had everything set up for a long talk. This was how the two best friends worked. Finally, it was time to break the silence.

Armin took a long drink from his glass "I think I might have been born in the wrong body, Eren. I think I want to dress girly more often, maybe even become one."

Eren clamped a hand over his mouth to avoid spitting out his drink. He swallowed it urgently, and looked at Armin with wide eyes "Are you serious?" At the hurt look on his friends face, he caught himself "I'm not saying it's a bad thing! You make a gorgeous female. I just...I didn't think that was your thing."

"I've been doing it for work, and realizing how happy and normal it makes me feel. I even want people to refer to me as female. At first, I thought I was non binary gender fluid, but I feel like I'm becoming more trans than fluid. I have felt like this for so long, but I was afraid. But I don't want to be afraid anymore. For the longest time I always felt like I was in the wrong body. That's why I grew out my hair. It wasn't enough. Then I went through a "straight period" but I knew deep down I liked boys Then I found out I enjoyed dressing like a girl. That's when I did the research and figured I was gender fluid. Boy clothes still felt wrong. I wanted to dress like a girl more and more. I'm a transexual. I want to transition, and be a girl. Do you still want to be my friend?"

"Hey, your my best fucking friend! No matter what you are, you will always be my best friend. I love you! I support whatever you want to do!"

"You really mean that?" Armin asked. Tears sparkling in his vivid blue eyes.

"Have I ever lied to you?"

"Oh Eren!" The blonde cried, tackling her best friend on the couch, and crushing him in a hug

"Aren't you worried those things might bust?" Eren yelled, trying to pull Armin off so her fake chest wouldn't get ruined.

"Fuck no! I paid a shit ton of money for these. They better take a whole hell of a major beating!" Armin answered with a giggle.

Once they settled down, Eren took a deep breathe. It was his turn "So, I had an amazing time. He was everything I wanted, and so much more."

"Really? Are you going to see him again?"

"I want to, yes!"

"Can he be discreet? I know that's a big problem for you. How much hush money did he need?"

"Not a dime. He didn't want my hush money."

Armin's eyes went wide "Seriously? Wow! Eren, you may have found the perfect dominant."

"It's not perfect...just good enough."

"He's gorgeous, he's knowledgeable, he's discreet, I fail to see a problem. "

"He's a stripper, with probably tons of clients. I'm a small fish in a barrel of many. You know I'm looking for a dominant to love me, and be in a relationship with. Until then, Rivaille is good enough."

Armin sighed "Oh yeah...You'll find someone Eren. I know one day you will."

"I know. I'm not upset Armin. I thank you though. If it wasn't for you, I wouldn't have found Rivaille. I see why his stage name is Captain. He definitely commands attention. It's very erotic."

"I'm still waiting for Erwin to politely ask me to get rowdy in his backseat. You think he'd mind a transsexual?"

"He calls you pretty and stuff, but he runs a gay strip club. It could just be a profitable business. You have a fifty fifty shot. Worst he can say is no."

"No, no is the least he could say. The most could be like is, get the fuck away from me you're disgusting. That's just the tip of the worst."

"So dramatic! You really are born the wrong gender! I don't think Erwin would be that type."

"Aww, thanks Eren! That's the sweetest thing you've ever said to me. No seriously, we've been friends forever, and that's the nicest thing you've ever said." Armin giggled. "I'm just kidding. You are the best Eren. You coming to the club again tonight?"

"Yeah, I think so. I just...I want to see him again."

"Don't fall in love with a stripper Eren. Remember what happened between me and Jean? I can't see someone go through that again."

"I know. I'm not looking for love, I just want him to dominate me. Love is a luxury I can't afford, but god I wish I could."
