He locks the door from the inside. You can only imagine what he might be doing right now, but it surely has something to do with the "carrot" in his pants. For a moment, your imagination forms pictures of Erwin, how he's touching himself while he moans out your name. How he's panting and how his body trembles from arousal. How big he might be...down there... You cut off your horny fantasies by slapping your face with both hands.

"Don't even think about it! You already have a boyfriend! And you love him." But you can't deny that you feel attracted to Erwin as well. Not just because of his amazing body, but also because of his character and kind nature. Ten minutes had passed since Erwin vanished into his room. And with each passing minute, you're sweating more and more, so as your concentration leaks terribly, which caused your game-character to die over and over again at the same place. Annoyed by yourself and your incompetence, you save the game and turn it off. Instead, you focused on watching Netflix. ~At least these pictures are moving on their own. No need for me to concentrate on it.~

After a few more minutes, you hear the key to Erwin's room clicking in the lock before he comes back, with messy hair. He tries to fix it before you would notice, but it's too late. That smartass seems to miss the fact that you almost counted every second since he disappeared and that your eyes only waited for the moment when he would come back. And he sits down beside you without saying a word. When he walks past your seat and you breathe in, a mind-clouding scent vapors into your nose. He smells like a strange mix of sweat, his body odor, and aftershave. And by strange, you meant fucking GOOD! This is absolutely the scent of sex! And it's amazing...He oozes pure pheromones and he has absolutely no idea what he's doing to you in his unshowered state. You're fighting the urge to ask him if he feels better now, but you bite your lower lip to prevent yourself from doing so. The situation is awkward enough. For minutes you sat side by side in silence. You can't stand this!

"Hey. There's a new episode of "Game of Thrones"! Want to watch it?" A terrible way to start a conversation, but it's better than nothing.

"With pleasure." He makes himself comfortable on the couch, stretching out his legs and putting one of his arms on the backrest.

When the episode was half over, you gaze at Erwin from the corner of your eyes. He's sitting in the comfortable curve of the couch, totally relaxed. ~How on earth can he be so calm while I'm not? I'm almost dying over here from tenseness!~
This is ridiculous! You can't act like this towards him just because he was reacting like a normal man would do. He's your friend after all, and he said more than once that you can trust him. And you fucking do! And he never forced you to do anything against your will. Such self-control, patience, and kindness haven't deserved to be punished with ignorance and avoidance.

"Erwin?" You asked coyly, but with newly gained self-confidence.

"Hm? What is it, sweetie?"

"May I...cuddle up to you? I'm freezing a bit." According to his expression, he didn't see this coming. After a short moment of thinking, he opens up his arms, inviting you into a warm embrace.

"Come here, sweetie. Let me warm you up." And you did. You crawl up to him, laying down on his chest and soon you, feel his arms around your body, caging you in a tight hug. Your head rests on his shoulder and you feel him breathing, his chest hovering up and down with every breath he takes. This is really relaxing and soothing. And he's so warm. Snuggled up like this, you watch the episode to the end. And when you reach out for the remote, Erwin doesn't make any effort to loosen up his grip. Only by stretching out your arm veeeeeery wide, making strange sounding noises of labor, you're able to reach it to change the channel. You hear Erwin him chuckling at your performance. ~Just like a very big child....~ you thought, rolling your eyes.

You switch through the different programs until you find a movie playing you both know very well. It was "The Hobbit: An unexpected journey". You gasp and Erwin immediately takes the remote from your hand to put it down.

"That's a good program-choice. Just leave it like that." He announced, bringing his hand up your head, gently pressing it against his shoulder. You feel so incredibly good right now. Warm, cozy, protected...and loved. Actually, this is totally wrong. Laying here in the arms of your boyfriends best friend was strange. But there is an urge deep inside you that drags you towards him. It's almost like he's hiding a woman-magnet under his shirt. You feel good around him and you want to let him know.

"Erwin? I think I have another birthday gift I want to give you." You murmured against his chest, with a huge amount of uncertainty inside you.

"Oh? And what might that be?" He asked curiously while you push your body up from your laying position.

"I...uhm...It's difficult to describe. I have it here. But before I will give it to you, you have to close your eyes. It's a surprise." Your body heat increases rapidly in unison with your heartbeat at the thought about what's on your mind right now. You're acting like an idiot! It's almost like you aren't able to think straight anymore. Your stomach is somersaulting and your hands tremble. But Erwin did as you said and closed his eyes. You lean closer to him until your faces are just inches apart and when Erwin feels your presence that close to him, his eyes fling open again. This was exactly the moment when you reduced the remaining gap between your faces, enveloping his lips in a gentle kiss. Actually, you wanted this to be a slight, tender friendship-kiss, to prevent yourself from getting lost into it, but Erwin had different plans.
As soon as he feels your lips on his, he pulls you as tight and as close to him as possible. His right hand braces your head and his other arm wrap around your waist as you gasp inside his mouth, but your body is totally unable to react properly right now.

This sudden passionate kiss is clouding your mind and your lips move against him in perfect sync as you embrace his neck with both arms to support your weight. Just for a brief moment, you break the kiss to gasp for air, looking into each other's eyes. His stunning bright-blue color had darkened a bit, lust and desire flaming up inside his story irises.

This is the first time you see the same spark of lust in them when Levi's seducing you. And damn...it seems Erwin is also a master in this kind of business. A true master. But before you can think any further about Levi, Erwin reunites your lips, kissing rougher and more passionate than before. It feels so incredibly good, his soft lips, moving against yours, hit hot breath tickling your skin and his breathy sighs he mouths against your lips. It's truly amazing. When he gently nibbles and licks on your lower lip, you willingly part them for him, welcoming his hot and wet muscle inside your mouth. Eagerly, he starts to explore every inch of your cavern, rubbing and stroking your tongue without fighting for dominance. He wants to feel you, surrendering to him without pushing you too far if you're not ready for it. Erwin's hot and greedy kiss robs the rest of your remaining mind and spit trails down the corner of your lips. Totally short of breath, you break from him once more, trying desperately to fill your lungs with air as you lick the mix of your body fluids from your lips. When it finally dawns to you what you're doing right now, you decide to stop here before this will lead you on a path from which you can't return. And when Erwin is about to pull you back to him, you cover his lips with two of your fingers. He was visibly disappointed, but this was soon replaced by a smile of pure happiness.

"Don't get used to it, Erwin. Today is your special day, this deserves a special gift."

While he licked his lips clean too, to collect all of the remaining fluids you granted him, he looks at you with sparkling eyes, with a satisfaction hidden in them you definitely haven't expected. "I won't, sweetie. And thank you for this special gift. It was definitely the best birthday gift I have ever received and it will always be. And don't worry. I won't tell Levi. This is our secret. You can forget about it if you want. But I never will. I will always remember the sensation of your lips, how they taste, how they feel. Everything." He cups your cheek with his huge hand, running his calloused thumb gently along your cheekbone as you sigh in relief. His sweet words make you shiver in delight and you snuggle up to him again.

"Then let's just enjoy the rest of the movie." He didn't reply. His arms that wrapped around your frame were answered enough. When you finally are fully back to your senses, you started to feel regret about what happened. What did the hell get into you? You can't play around like this! Why are you acting towards Erwin as if you're.......in love with him? No! This can't be! You can't fall for your boyfriends best friend! You love Levi! More than anyone before! You can't let your stupid hormones make you crazy and foolish. Friendly cuddles and hugs are one thing, but you will definitely stop this before it's going too far. You can't have both. Either you will lose Levi when he finds out and that you lied to him, or you will lose both if you tell him how you feel. This was the last time you did this, no matter how attractive Erwin is and no matter how bad he turns you on!

Levi's P.O.V.

It was pretty late. It's long after midnight when I finally arrived home again and I began to wonder what Nina and Erwin had done today. Maybe I can ask them about that tomorrow, or later, to be specific. When I open up the door to the penthouse, I hear the TV running.

~Stupid girl! I told her not to wait for me! Why is she always disobeying me? I guess I have to set her straight about this.~

I couldn't withstand to let my mind perform dirty thoughts about my own inner monologue as I undress from my coat in the hall. I lick my lips in expectation while I sneak up to the couch to surprise her with my sudden appearance but as soon as I peek over the backrest I discovered the most disturbing and most peaceful picture I've ever seen. Nina was laying on Erwin's chest, her arms laying loose beside his body while his own were wrapped around her back. Both tightly asleep with the TV running. I sigh. At least she did one thing right I told her in my note. She took good care of Erwin. Normally, he isn't celebrating his birthday. It's a regular day for him. Just like my own birthday is for me. Seeing him here, smiling in his sleep while holding my woman in his arms like a plushie, it makes me kinda jealous. But to wake them up right now just to drag her in bed with me would be cruel. But I will not let her sleep here any farther too. I look at my watch again. After midnight, which means, Erwin's birthday is officially over.

I sigh slightly as I walk around the couch, where I first turn off the TV, then turning around to remove Erwin's arms from around my woman as careful as possible, to avoid waking them up. He grunted in his sleep when I was working with his arms and I froze for a split second, but when I was sure that there's no danger, I continued. Once I freed Nina from his grip, I take her in my arms, carrying her bridal style into my room, where I place her carefully on her side of the bed. I undressed her out of her clothes until she's just left in her underwear. She looks so beautiful like this. Tightly asleep with nothing more than her delicate lacy lingerie on her. I bite my lower lip to shush my inner screaming animal and quickly cover her with the blanket before I undress as well to lay down next to her. My arms automatically wrapped around her waist, pulling her close to my chest, like several times before, to rest my cheek on her head. I immediately feel the satisfying warmth running through my body that radiates from her like light from an open fire. Her low breathing, her steady heartbeat and her soft skin against mine. Feels like heaven on earth. How could it happen that I got attached to her so close in such a short time? It's unbelievable that we lived in the same city, so close to each other for so many years without meeting earlier.

It scares me that I'm connected to her in such a close way. I hate it and I love it at the same time. But what I can say for sure is, that I'll do anything that's possible to make sure that she is okay and happy around me. Anything...
