Levi watched Shinobu and Eren talk while leaning against a wall, arms crossed. Shinobu smiled at Eren like usual while listening to whatever he was talking about, and giggled softly at something he said.
"Come on Eren, you're talking nonsense." Shinobu said and shook her head softly.
"Oh, yeah? Just watch me Shinobu!" Eren said as he chuckled softly. Who knows what they were talking about.
Levi huffed softly and walked over to them, he didn't look too happy.
"Evergarden, my office, now." Levi said as he glared down at her. Eren and Shinobu looked at each other quickly, both wondering what she even did wrong. She nodded and walked with Levi to his office, still wondering what she did wrong as Eren looked after them. Levi opened the door for her, and when she walked in and sat down he closed the door and sat down as well. Shinobu looked at Levi in silence, waiting for him to say something. It was silent for a few seconds before Levi spoke up;
"So.. Enjoying your time with Eren, huh?" He asked in a cold tone.
"What.. Do you mean?" Shinobu asked as she tilted her head slightly.
"You know exactly what I mean." He huffed softly and looked to the side for a split second but then back at her.
"Of course I'm enjoying my time with him! He's my friend after all." She said and smiled again.
"..Why would you ask that all of a sudden?" She continued.
"You talk with him quite a lot." He said and looked at her.
"..You're not jealous, are you?" She asked as her smile grew.
"What? Of course not! What the hell makes you think that? Don't think too much of yourself!" Levi huffed softly.
"Oh, Levi! Eren and I are just friends, I like you way more and you should know that.." Shinobu said with a soft smile.
"Yeah yeah.. Don't make a big number out of it." Levi huffed softly again and blushed lightly, and looked to the side.
Shinobu giggled softly and leaned closer to Levi.
"Don't be like that darling! I can prove that I love you and you only." She said with a smile on her face, like always.
"How were you planning to do that?" Levi asked and looked back at her, he didn't seem so 'mad' anymore.
Shinobu's smile grew as she walked over to Levi and sat on his lap. She wrapped her legs and arms around him, and started grinding against his body. Levi looked surprised and blushed slightly as he grabbed her hips gently.
"W-what are you doing??" He asked and looked up at her.
"Proving I love you only!~" She said with a smile and ground harder against him, before unzipped his pants.
"Shinobu hold on! Are you sure it's a good idea to do this right now? ..Right here?" He asked as the slight blush on his face grew, and he got a bit nervous. He let go of her hips and glanced to the side but then quickly back.
"Relax Levi! I'm sure no one will come in here.." She said and blushed lightly. She quickly took her underwear off along with her pants.
"Shinobu-" Levi started but Shinobu stopped him.
"Calm down already.. A little bit of fun can't be that dangerous!" She said with a lustful smile as she took Levi's pants and underwear off as well. She bit her lower lip and started riding Levi.
Levi gasped slightly and grabbed her hips pretty gently again, his blush just growing. Shinobu went pretty slow at first, but then she sped up a bit and let out a soft moan. Levi's grip on her hips got a bit tighter as she sped up some more.
"Mmh~ n-not so bad is it?" Shinobu asked as he kept riding him pretty fast.
"H-hey, slow down a bit-" Levi muttered, ignoring her question, but his face answered it. Both of them were having fun for sure.
Shinobu giggled softly as she slowed down just a tiny bit and kissed Levi softly. He kissed back of course, but stopped after a few seconds and kissed her neck instead. She yelped slightly mostly in surprise, but that didn't stop her from riding him. Instead, she just sped up again and moaned softly every now and then.
Levi stopped kissing her neck and just looked at her for a bit, both of them were breathing heavily and blushing.
Shinobu kept going for a while, speeding up and slowing down at different times. Suddenly Levi's grip on her hips got super tight as he came inside her. She gasped slightly and stopped.
"You could've warned me!" She huffed softly between her heavy breaths.
"S-sorry angel.." He muttered as he let go of her.
She stood up and looked down at Levi who was still on the chair.
"What a mess.." She muttered.
Levi stood up carefully and looked down at the floor, at their clothes. Shinobu was already on his bedroom's door though, she opened it and walked in. Levi didn't even bother to say anything as he walked after. They cleaned up and changed into new more comfortable clothes, though Shinobu wore Levi's clothes since she didn't have her own clothes there, obviously.
They both went to Levi's bed and cuddled each other, both still a tiny bit exhausted. Shinobu kissed Levi's cheek quickly and closed her eyes, and after a bit she was asleep, still hugging Levi. Levi glanced at her and smiled slightly, and eventually he fell asleep too.
