Armin was shocked. I spread his legs, positioning my head above his waist. I took a small test lick before engulfing his whole penis with my mouth. He moaned in pure bliss. "Y-Y/N, don't do that. Please don't dirty yourself for me..." he panted. I looked up at him, taking him out of my mouth. Armin was conflicted. Part of him desperately wanted to be touched in that way, but the other part of him felt guilty. He felt like he was defiling me, albeit he wasn't. "How am I dirtying myself? Doesn't it feel good?" I asked. "O-Of course it feels good, it feels amazing, but I don't want you soiling your mouth on my dirty body," he explained. 

"Armin, your body isn't inherently dirty like you seem to think it is. If you really felt that way about yourself, how would you ever expect us to be intimate with each other? That was what you wanted, right? Being intimate with someone in different ways isn't wrong, nor is it any dirtier than just having sex. If you're uncomfortable doing something like this then that's a different story. Just say so. But if this is about you feeling like you're doing something that hurts my dignity, then you're just wrong," I told him.

Armin felt bad. He realized his views really were about dignity. He felt like he couldn't forgive himself if he let me defile myself through deviant sexual acts, but at the same time, he craved it. So, he allowed it. With his nod of approval, I resumed. I started off by grabbing his shaft, licking the tip. He winced. My warm, wet tongue swirled around his tip. Precum was quick to come oozing out. Armin panted as I began making my way down his shaft. My tongue ran up and down. My face was pressed against his inner-thighs, I could feel them tensing up. His toes curled as he clawed onto the bedsheets.

Eventually, I felt as if I'd teased him enough. After all, we weren't doing this as an intentional way of being intimate together, it was more so just to help him out. I positioned his head at my mouth's entrance. It felt both so wrong and so right, to him. All at once, I took him in, stopping once my lips reached the bottom of his shaft. He writhed with pleasure. I began quickly bobbing my head up and down, focusing on the tip when I got the chance. His cock was so hard. It almost hurt when it continuously hit the back of my throat. Thankfully, my strong gag reflex wasn't kicking in as quickly as usual. I finally pried my mouth off of him, getting a whimper in return.

"Calm down, I'm not stopping. I'm just trying something different," I purred. I pushed up his penis with my left hand, moving it out of my way.

"Y-Y/N what're you-"

I took him by surprise, taking in a mouth full of his balls. He involuntarily swung his hips up at me. I tongue lapped around his balls, lathering them in my own saliva. His hips gyrated pleasurefully. "Y-You don't know what you're doing to me Y/N..." he panted, "I-I don't know how much longer I can hold myself back. Please stop... I don't want to get you dirty..." I ignored his begging. I wanted him to be more comfortable in his own body. He shouldn't have had to think that an act of intimacy, like such, would be dirtying his partner. I sucked on and licked his balls, receiving pleasurable moans from up above. They were clearly a sensitive spot.

"Y-Y/N, please stop!" he warned again, this time yelling. At this point, he wasn't afraid of his bodily fluids defiling me, he was afraid of losing control. It was too late. To my surprise, he shoved my face into his crotch, making it a bit hard for me to breathe. I was being smothered by his precum, tears began pricking at the corners of his eyes. He hardly refrained from gyrating his hips. As much as it may have been uncomfortable, I was fine with it. I mean, I didn't mind getting to see a more forceful side of him. All of a sudden, he climbed up onto his knees, trembling. My mouth pried off his balls just to get a mouthful of penis, which he shoved into my mouth. "Y-Y/N... I-I'm sorry! I-I can't control my body," he cried. He felt betrayed by his own body. It was completely on autopilot, giving into his darkest desires. Since I was in a tabletop position, he folded his torso over my head and back, wrapping his arms around my stomach. He finally got up onto his feet, tears pouring down his face and onto the back of my shirt. "Y/N, I'm... I'm so sorry. I don't know what I'm doing, I can't stop!" he screamed in complete emotional agony.

Out of nowhere, he began thrusting deep and fast into my mouth. It hurt, almost making me gag. I felt like I might throw up. His pace quickened, faster than I thought was possible. Just as I'd gasp in for air he'd thrust back into my throat. His face was pressed into my back, he wailed. Armin kept apologizing, feeling terribly guilty. It was pathetic, he almost looked like a dog mating, how humiliating. It did hurt. Could he really not control himself? He was being very rough, considering his gentle nature. Armin moaned and cried loudly into my back. The urge to ejaculate was so bad but he felt like he mentally couldn't. I could tell he really was sorry. 

Clear beads of sweat ran down his body as he made all sorts of erotic noises. His voice was high pitched as he clawed at my stomach with his nails. I was surprised by how he kept his fast pace. The boy had some stamina. Even after this long, most people would have gotten tired. I was exhausted and I was just sitting there. I eventually noticed he started slowing down, finally. Once he stopped, he shoved me down onto my back. I guess he wasn't done. Armin continued from where he left off. Powerful thrusts in and out of my mouth. I seriously felt nauseous, so much so that I worried I might vomit on him. He was in a frog position, laying down with most of his body weight on my head. His arms were above his head, gripping the edge of the bed. His rhythm was even faster than before.

As he hit the back of my throat, involuntary gargling noises came out of me. Suddenly, he swung his cock out of my mouth and used his hand to position his balls in it. I guess that really was what his body preferred. He apologized, "I-I'm s-sorry, Y/N. I'm s-so repulsive. I just wanna die, this is so sick of me. I can't believe I'm hurting you like this, right now." I wanted to tell him that it was alright but unfortunately, my mouth was a little too full. Well, at least it was better than him humping my mouth. It hurt, so this was a well-deserved break. My tongue swished and swirled around his balls, shifting them in all sorts of directions. He squealed and moaned in pure pleasure. They were so tense, which I imagined must have been incredibly painful for him. "Y/N, I-I feel it. I feel like it's gonna come out and I don't know what to do..." he whined. Armin's eyes were pierced shut as his respiratory rate increased. I started speeding up with my tongue work. He shoved his crotch into my face, suffocating me.

"Y/N! It's–"

Just then, he cut himself off with a loud moan. He arched his back as his white seed spurted out everywhere. There was so much. It got all over my face and hair, as well as his stomach, and arms. It was a disaster. He panted raggedly as his body and penis became limp and flaccid. It was finally over, thank God. I managed to push his frail body off of my face. His eyes were closed. "You better now?" I chuckled playfully, trying to maintain my composure. Armin opened his eyes, his expression immediately changing as he began to cry. "You're a mess, all because of me. I hurt you and couldn't even stop myself. It's completely unforgivable!" he wailed. I felt bad for him. His body had defied every ounce of logic he had left, making him commit an act he would have never normally done. Armin covered his face with his semen covered hands and sobbed loudly. I lay down, my face close to his, and took pried his hands away. He squeezed his eyes shut, not wanting to see my face. He was afraid of me, afraid that I was angry at him. 

"It's okay," I reassured him, "you said that you weren't in control. I completely believe that. Even if you were in control, I wouldn't be upset with you at all for it. I'm not mad at you and I don't regret any of that. I love you." He opened his tear-filled eyes and looked at me. I almost felt like I wanted to cry with him. I asked him if he felt any better. "Yes. I'm so sorry, Y/N," he sobbed. I held his wet hand, tight. I told him, "it's okay Armin. There's nothing you need to apologize for."

"I hurt you, Y/N. That wasn't right!"

"I'm fine, you didn't hurt me," I lied. He rolled over onto his side.

"I did. I know you're lying..."

"I'm not. Let's just drop it, please."

Armin knew this wouldn't actually be forgotten. He felt terrible and genuinely wanted to die. It was humiliating, he was so embarrassed. He desperately did want to move on, though. "I'm cold," he whimpered. "I have an idea. How about we go to my house and we take a warm bath? We can get into some comfy clothes and then go to bed, after," I suggested. 

"Yeah, that'd be nice."

Armin used all of his strength to get up into a sitting position. He put on his underwear and pants, after all, he did have some decency. He wasn't just going to go to my house half-naked. Although he knew I wouldn't have cared. I got up and drew out a portal. Armin tiredly stood up and grabbed my arm. I guided him through the portal, back into my world.
