I kinda left it open for more smut, so here it is!

Levi groaned as he watched Eren continue to clean his torso with his tongue. It was for various reasons. A small one was that he was still trying to study. The bigger ones were how turned on he was becoming by watching Eren, goddamn, he's sexy, and how his tongue would leave wet trails that made him shiver when the breeze from the window would hit his body.

He couldn't complain though, he was enjoying it. Eren's tongue felt amazing, and the temperature change provided a sensation he hadn't felt before. He ran his fingers through Eren's hair and tugged slightly, Eren bit at the skin at the end of his ribcage in return, which only made Levi chuckle.

"I thought I was getting a blow job, not a bath," Levi teased.

"I'll stop now if you keep talking," but he continued.

Levi lowered his voice, "but I thought you liked listening to my voice, I thought it turned you on, Eren,"

He felt Eren stiffen but instead of stopping, Eren started to lick up his torso and to his neck. Biting and sucking hard, Levi couldn't keep in his moan.

"It turns me on so much," Eren whispered into his neck as he continued to mark all over Levi's neck, shoulders, and chest. After a while, Eren pulled back and started shuffling around, Levi opened his eyes, not even realizing at what point he closed them. He saw Eren get up off him and he offered the best pout he could. Eren grabbed his hand and pulled him up so Levi was sitting and then he got off the bed, kneeling at the foot of the bed.

Levi got the idea and sat at the edge of the bed, Eren put his hand over Levi's length and immediately began to pump him until he was fully hard again. Once he was, Eren kissed the tip of his dick and licked a line down the underside, putting pressure on the vein running through there. Levi had to bite his lip, trying to keep in his moans, but that failed when he felt Eren's nails dig into his thighs and his balls encased in warmth.

Then he finally took Levi into his mouth, agonizingly slow, Levi moaned when he felt the head of his cock hit the back of Eren's throat. But warmth and the wetness around him didn't make him feel as good as knowing that Eren liked to do this for him. Eren had been moaning almost as soon as he had taken Levi into his mouth. The vibrations doing wonders to the sensation.

Levi could feel Eren's tongue swirl around whatever of his dick it could, and his teeth gently scraping him were a pleasure wanted so much more of.

He had tangled his fingers into Eren's hair, holding him in place even though he knew Eren wasn't going to stop until Levi was completely satisfied. He used his fingers to help Eren bob his head, making him pick up speed and Levi moaned again. If it weren't for Eren's hands on his thighs, he would have been ramming his dick into his mouth the moment they started, but he didn't do it, he didn't want to hurt Eren. They had never done that before, so Levi didn't know if Eren would even like it.

One of Eren's hands moved away from his thigh and started to pump at Levi's length while Eren focused on the head. He swirled his tongue around it, dragging his tongue across the slit and moaning at the taste of Levi's precum. Levi had to take his hands away from Eren's hair and grab the edge of the bed to control himself.

Eren sucked hard and Levi moaned again, throwing his head back with the pleasure, but Eren pulled back to soon. Levi meant to scold at him when he looked back at Eren but Eren took him by his hand and stood him up, kissing him hard. Levi could taste himself in Eren's mouth. Eren turned them around so that now his back was to the bed.

"Levi," he said when they pulled back, his voice slightly hoarse, "I want you to fuck my face,"

"Ar-are you sure?" Levi asked.

Eren hummed a response as he kissed Levi again and started to pump him again with his hand. As soon as Levi nodded, Eren got on the bed on all fours, facing Levi, his face aligned to Levi's cock. Levi moaned at the sight and Eren grabbed his hand, pulled Levi closer, that same hand then worked its way to the back of Levi's ass, so he could push Levi into his mouth. Levi didn't move once he was all inside Eren, letting Eren get ready.

He felt Eren's jaw relax around him and Eren pushed at his ass, beckoning him to start. Levi thrust in slowly, and gradually beginning to go faster with Eren's encouragements. After a minute or two, he was going faster and harder. Eren moaned around him and swallowed every now and then when Levi hit the back of his throat. He was even starting to try to meet Levi's thrusts, pushing him and sucking him deeper into his mouth.

Levi watched as Eren took the hand that had been on his ass and started pumping himself. Levi was turned on knowing this turned on Eren. He was taking him in so well.

Eren started to moan more frequently and the added vibrations were pulling Levi over the edge. He felt Eren give one very long moan and that was all it took for him to cum inside Eren's mouth. Levi watched as some of it dribbled down the side of Eren's mouth and onto his chin. Eren swallowed around him, and then swirled his tongue around Levi's now soft cock, making sure to pick up all of his seeds. When he pulled back, Eren lifted a finger to catch what was on his face and sucked his fingers while he looked up at Levi.

But then he rolled onto his back, exhausted.

Levi leaned down and kissed his forehead, "do you need some water?" all Eren could do was nod, so Levi took a water bottle from the case he kept beside his bed and opened it, helping Eren sit up. Eren drank a couple long gulps, "better?" Eren held the water bottle in his lap and nodded again, "I love you," Levi told him as he kissed him again.

Eren told him he loved him too, but his voice was so raspy and hoarse, Levi laughed at him, "I know you do, love," he kissed him again, but then he got serious, "I didn't hurt you, did I?" Eren shook his head fervently. Levi sighed in relief and then got up, grabbing some shorts from his dresser and slipping them on before picking up Eren's sweatpants from where they had fallen to the floor and helping him into them.

He let Eren pull him onto the bed and kiss him again once they were both laying dowm "are you sure you're okay?" Levi asked him.

"Yes, Levi," Eren said, his voice still a little raspy, "you can go study now," Levi chuckled as his words, he was too exhausted to study now, not to mention Eren had his arms tightly wound around him, he wasn't going to let go.

"Nah, I think I'd rather stay here," Levi told him.

Eren kissed his cheek, "good,"
