My Girlfriend is an S-Class Adventurer

As Luke heard Nathalia's voice, he got up from his bed and walked to the door. As he approached, he noticed that, for some reason, the young woman's heart was racing, so he hurried to open the door.

When the door opened, the half-wolf saw the flushed face of the white-haired Elf, who was wearing a casual outfit. Her pink shorts were short, and her white shirt went only halfway down her belly, highlighting her breasts.

"D-do you need something, Nath?" he asked, with his heart pounding because of the girl's beauty.

Looking down, Nathalia pouted and muttered something practically inaudible to normal people:

"I lied about the homework... Actually, my roommate is having sex with her boyfriend, so I can't stay there..."

Thanks to the half-wolf's super hearing, he could hear the words clearly. Therefore, he widened his eyes and stepped out in front of the door, so he could let her in. "I understand... Come in, wait here as long as you need."

"Thank you..."

Since it was getting late and they both needed to get up early for class, Luke let Nathalia stay in his bed, and he lay on the floor after covering and spreading out some blankets. Before that, he blew out the candle flame, and now only the weak moonlight, which came through the white curtain of the window, illuminated the teacher's small room.

Curled up in the bedcovers that Luke had previously been reading books on, Nathalia could smell his scent impregnated into the wool.

'Sometimes I forget how good he smells... Oh my God, I'm in Luke's bed at this exact moment? I just realized that...' She thought, and her heart began to speed up even more rapidly. For her, this was absolutely out of all proportion.

Luke wasn't getting any sleep either, and when he heard the Elf's heart begin to beat faster, he turned to her and asked:

"Are you okay? Do you want me to go downstairs to get a cup of water?"

Hearing the half-wolf's thick voice, she startled a little. "W-what? N-no... I'm fine... I mean, I'm actually a little scared." Nathalia saw a possibility.

" Scared? Scared of what?" Luke lifted his backside to get a better look at her.

Nathalia looked away as if she was embarrassed. "Of the dark, I guess... Can you lie down... with me?"

Hearing this proposal, Luke's eyes widened. "All right..." He accepted without much thought. Now it was his heart that was very restless.

Then, Nathalia moved a little further to the corner of the single bed, while slowly lifting the blanket.

The half-wolf lay down beside Nathalia and looked at her. The Elf's face was almost as red as her eyes.

"Do you feel safer now?" He questioned, looking her in the eyes.

She was avoiding looking directly at him, although their bodies were almost touching under the covers. "Y-yes... You make me feel safe, Luke. That's why I risked coming to your room, even though students are forbidden to enter the teachers' dormitory."

"Erhh? Is that forbidden? Well... it's late now, I couldn't just not allow you in. The campus can be dangerous at night." He replied, sounding nervous.

If someone had heard or seen Nathalia, they were both in serious trouble.

After the half-wolf's words, the Elf mustered the courage to look into his eyes.

When the girl turned her face and looked deeply into his eyes, for some reason, Luke didn't feel like looking away. The silence and darkness of the night made all senses and sensations even more intense.

Hypnotized by Luke's golden eyes, Nathalia stared at him for a few seconds at a distance of fewer than twenty centimeters. She never had the opportunity to see those eyes so close, much less in the dark of night. To her, the half-wolf's eyes seemed to be the most beautiful eyes she had ever seen. She wished she could have been born with those eyes, instead of her red eyes, which she had hated for a long time.

"Can I see your eyes more closely?" She asked.

Charmed by the Elf's red eyes, Luke didn't think to answer. "Yes, of course."

Nathalia moved a little closer, dragging some of the sheets that covered the bed. Now the faces of the two adventurers were less than ten centimeters apart. Without difficulty, they could hear and feel each other's eager breathing. Both weren't thinking correctly.

Therefore, when Elf's gaze rested on Luke's lips, he didn't hesitate, and on an emotional impulse, he kissed her. The girl wasn't surprised by the kiss, because she was thinking the same thing.

As soon as their lips connected, it felt like a huge weight had been lifted from both of their backs.

Their warm bodies made the feeling more intense, and when their legs touched under the covers, the kiss became even better. Luke had secretly wanted something like this since the first moment he saw Nathalia, who spied his arrival through one of the windows of the Vasconcelos Mansion. After that, he saw her spying on him other times, but never connected that this could be something romantic. Now it all made sense.

While their tongues curled, the half-wolf let himself be carried by the moment, and with his right hand, he groped the Elf's breast over her white shirt.

"Awnn! Wait a minute, Luke..." She said low in her thin, gentle voice.

Nathalia's groan brought Luke back to reality. Before, he wasn't reasoning correctly, so he immediately pulled away from her. "You're right, Nath...we can't go on with this." He determined.

She was surprised because everything was going well. "No, that's not what I wanted. You can touch my breasts! I just startled a little!" She took his left hand and made him touch one of her breasts.

"N-not that." He acted calmly and removed his hand from the Elf's boobs. "You and Ayumi are daughter and mother...and I think she might not agree with that..."

"You had sex with her and Alexis, didn't you? Why wouldn't she agree?"

He startled. "Y-you already know?"

"My room is simply beside my mother's room, how can I not hear the moans of the two of them on that night?" She narrowed her eyes and stared at Luke.

He looked away. "Even so... I'm still in a relationship with both of them, and Ayumi could maybe end up hating me for staying with you..."

Nathalia's cheeks inflated, but she seemed resigned. "That's exactly what made me like you. You're innocent sometimes, dumb and a jerk a lot of the time..."

Luke accepted the offenses without complaint; after all, he was aware of his faults.

"But you are also loving, loyal to your principles, sincere, a great instructor and teacher, and as much as it may be surprising to you, you are also very smart sometimes..." She said with a blush on her face.

These words made Luke realize that Nathalia's feeling wasn't just sexual desire, but something more profound, and even so, he couldn't betray his ideal of fidelity.

Luke smiled at her and said:

"Thanks for the words, but I still can't... Well, I'm going back to the ground, so we can sleep. We should talk more calmly later, maybe after this period has passed."

Before the half-wolf could get up, the Elf grabbed his shirt sleeve and forced him to stay on the bed. "I'm still scared, stay here."

Reluctantly, he consented because he didn't believe she could be lying about it. The moment they lay down and exchanged glances again, he looked into her eyes, and she could tell he was uncomfortable.

"A-all right...I'll turn around, so you can be safe that I won't attack you."

"W-w-wait, Nath... This way is wor—" Nathalia turned her back to Luke and felt something touch her ass, making her jump in fright. "Aw! What is that?"

Before she could turn around, Luke jumped off the bed and lay on the floor again. "It was nothing! Good night!" He exclaimed and lay down with his back turned to the bed.

Upon finally noticing what it had been, Nathalia turned to the wall again, but now she was more flushed than ever.
