At 9:40, you ask Levi to accompany you to the library to retrieve the lost item that you hadn't really lost. You had battled with yourself on whether or not you would ask Levi to accompany you but in the end, you did, for one of two reasons. The first one was the fact that you still wanted Levi's protection. Although the letter was signed "E" it would be naïve to think that the only person it could be was Eren. It could be someone who was just testing how well you followed instructions or a person with bad intentions, but if Levi was there, at least from your room to the library you would be safe.
The second reason was because you knew that there was no way in hell Levi would ever let you go alone. He never let you out of his sight during his shift unless you were in the bathroom or getting dressed with Sasha. Plus, you were sure he was already suspicious, having you trying to convince him not to accompany you to the library late at night wouldn't help your lie very much.
Upon reaching the library you turn to Levi before he can open the door for you. "Just wait here, I'll go in and grab it real quick."
His eyes narrow once again, "What did you leave in there anyway?" he questions. You rack your mind for anything, it was unlike you to not be prepared for a question like this.
"The bracelet Eren gave me, I took it off when I was reading and forgot to put it back on."
Immediately his eyes fly to your right wrist, where the bracelet always sat unless you were sleeping. You consciously shift your left hand out of his sight so he can't see the bracelet there. For some reason, you had decided to change it up this morning and that last-minute decision saved your butt. He nods and turns away from the door watching for anyone in the hallway.
You open the door and enter into the pitch-black library alone. The beautifully light and airy room that you loved so much in the day was eerily dark and silent at night. Giving a few seconds for your eyes to adjust to the absence of light, you suddenly wish Levi was by your side. It's scary how big and open the library was and you wonder if Eren was already here. Your slippers help your footsteps to be silent and your ears listen for any type of sound as you slowly walk between the shelves. Finally, you hear a few whispers, so soft that you wonder if it's your mind playing tricks on you but then you see the small glow of candlelight. You're all the way in the back, there's no way the light would be seen unless you were in this spot and there's no way a person would have been able to get to this spot without any light unless they had spent as much time in the library as you did.
You try your best to conceal your presence, barely breathing to see who it is. You peer around a bookshelf and almost gasp at the sight. Historia was sitting on top of a table, the candle a few inches away from her wide open legs. You can tell who is between them from the back of his head: Eren.
Historia's head rolls back as she pushes his head deeper into her folds and you want to stop looking, you want to stop watching the erotic scene before you but it is the first time you are seeing such an act. You had read about sex millions of times in the romance novels you buried your head in but you knew that those were still books at the end of the day. Just the figment of the author's imagination, real sex, you had thought several times, was probably much different. Real sex was like this.
You can tell Historia is trying her best to keep her moans quiet and Eren peers up at her while continuing to eat her as if he's starving.
"E-Eren, what if someone-" a breathy moan escapes her lips before she can continue, "-finds us."
Eren pulls away and she whimpers at the absence of his touch, "Nobody would come here this late and I sent Mikasa on a wild goose chase to get rid of her. You also made Ymir run an errand for you so we're good. Just relax," He says right before diving his tongue right back into her.
