I have decided to practice my smut writing skills (because believe it or not, it is a legit goal of mine to get better at it). I will be taking ereri/riren smut requests. I may not accept them all but I will try my best. I will go for the ones that are most appealing to me or that give me enough inspiration to write. So making your request as descriptive as possible will most likely give it a better chance of being accepted. Any requests are nice, there will be no fetish shaming. We all have our kinks. But no rape or stuff like that, that's off limits. These may not be very good at first but I hope for them to get better the more I write them so that one day I may be as good as my writer senpais when writing smut. X3 I may not update this very often because I tend to stick to my main story that I am writing, which at the moment happens to be "The Vampire and the Brat" but I will do my best.

This was totally based off a vine and I'm not even that sorry. This is my first time writing smut so please go easy on me. But I would absolutely love to hear suggestions on how to get better. (God I'm so embarrassed right now lol)

Doctor's Orders

(Eren's POV)

"Doctor, I think there is something wrong with me." I say, looking over to Levi who is standing in front of where I am sitting.

"Well what seems to be the problem Eren?" He asks, coming closer to me.

"Well, I have this lump on my thigh…"

"Here?" he asks, resting his hand on my knee.

"A little higher."

"Here?" he asks again, moving his hand to the top middle of my thigh.

"A little higher." I say again.

"Here?" he asks, moving his hand onto my crotch and feeling my erection through my pants.

"Ahh! T-there!" I throw my head back as he palms me through my pants.

"Ah I see the problem now. I have just the idea that might help." he says huskily in my ear, licking the shell and causing me to shiver. He moves to my neck and starts kissing and sucking on the sensitive skin there as his hands start to undo my pants and take them off. He starts trailing down but stops at the collar of my shirt.

"We are going to have to remove this." He says, tugging at the hem of my shirt. I lift my arms up so he can take my shirt off. Once it's off, he continues where he left off, trailing kisses down my chest and down to my stomach. I moan at the sensation as he continues to trail down, getting closer to my now visible erection.

He takes my cock in his hands and licks the tip, making me shout in pleasure. He then takes the tip in his mouth and starts sucking gently on it while his hands pump up and down my length.

"Ahh Levi!" I shout, threading my fingers through his hair as he takes more of me into his mouth, his tongue swirling around the tip as he comes up and then going back down without taking me out of his mouth.

He continues to suck up and down, stopping to lick the tip every so often. I can start to feel the familiar feeling of the knot forming in my stomach, signaling I'm close.

"Ahhaa Levi I'm about to-!" He starts sucking faster, going deeper down onto my length. My hips start to buck up to meet him and he presses them down in place with his hands. Soon I can't hold it back anymore and I cum in his mouth. He swallows it all before coming up and smashing his lips onto mine. I start kissing back immediately; his tongue glides over my bottom lip asking for permission to enter. I open my mouth, letting his tongue enter my mouth. Our tongues twirl together, fighting for dominance, I can taste myself in his mouth. Of course Levi wins the battle and then pulls away. We're both panting now.

"Well that didn't work. You're still hard. But I have another idea that should work." he says, grabbing my still hard cock in his hand and pumping slowly. "Suck." he says, pressing three fingers to my mouth. I take them in and suck on them, swirling my tongue around them as a I go. Once his fingers are too his liking, he pulls them out of my mouth. "Now lay down on the bed on your back and spread your legs." he instructs.

I nod and do as I'm told. He quickly throws off his shirt and pants and climbs on top of me. Kissing me passionately as his finger starts to prod at my ass. I moan into the kiss as he sticks one slick finger inside of me, pumping in and out. He soon slides in a second then a third finger into me, prepping me. As he does so, he moves from kissing me to kissing my neck. He sucks and licks at the sensitive skin, leaving a mark. Once he is done he pulls away to look at his work proudly.

After a few more pumps from his fingers, he removes them, positioning himself in their place. "Are you ready Eren?" He asks, getting ready to go in. I nod in answer and he slowly starts to slide in. I can feel tears starting to form in the corners of my eyes as he slides in. He presses his lips to mine, kissing me to help distract me from the pain. Once he is all the way inside me, he waits so that I can adjust to his size. Once I have a adjusted, I pull away from the kiss.

"You can move now." I say. He takes no time in starting to move in and out of my hole. I can't help but moan at the sensation. I scream in pleasure when he hits my prostate. "Aaahhh! Levi! Right there!" I yell. He repositions himself so that he is angled to hit my prostate again and again. I'm a moaning mess by the time I feel the knot start to form in my stomach again. "Levi! I-ah! I'm gonna cum!"

"I'm close too." he grunts, starting to go faster, hitting my prostate harder. He grabs my cock and starts to pump it. "Cum with me Eren." He starts going even faster than before. Pumping my length just as fast.

He slams into me one last time before he stops and I can feel his cock twitch and his cum start filling my ass. The sensation bringing me to cum along with him; all over his hand and my chest.

Levi stays put for a bit, catching his breath, before he pulls out, leaving me feeling empty, collapsing next to me on the bed, still panting slightly.

"That was amazing." I pant.

"Yeah." he agrees. "I love you Eren." he says, pulling me into a passionate kiss. I kiss him back just as passionately before pulling away and replying.

"I love you too, doctor." I say, nuzzling my head into his chest. I can hear him laugh quietly at my reply before he pulls the covers over us and wraps his arms around me.

"Go to sleep Eren." he says, and we both fall asleep, wrapped up in the blanket together.
