WARNING; THIS PART MAY

I am really sorry if I didn't warn you before, but if you want to continue, carry on! >_<"

He looked at you and gave you a little smile, "Oh really? I don't know what to say, Y/N... T-that's really sweet of you, dear..." He shutted down the computer and slowly, he came to you, "E-ehehehe... well, you really are! I only met you a few days ago, and you're already, so nice to me... like we've known eachother for a long time..." You said, slowly moving from the corner of the bed, "W-what are you going to do... hahaha..." You asked nervously. "You've been really nice to me, miss Y/N. Even if you don't show that, I could feel it." He went on the bed and crawled all they way to you, he had a strange smirk and he wraped his hands around you. "'Just kidding'. I would never hurt my lady." He hugged you tight and you hugged back again. You looked up to him, and he kissed your forehead, "This is what you do when you want affection, do you not?" Your face was super red. It wasn't on purpose but you suddenly kissed him back, on the lips. "O-oh, Gaster I am so sorry-" You were cut of by another kiss. This time, his tongue was inside your mouth, it was really cold, it felt good. You battled with his, and he... moaned a bit? Your mouth was really messy this time. Purple saliva-like, liquid was dripping down your chin. You wanted more but you needed air, so you broke the kiss and looked away, wiping the saliva off. "O-oh... I... Y/N... i'm so sorry..." He was blusing really deep blue. "I-it's okay... I got carried away too..." You mumbled. "S-so what now... Y/N...?" It was really akward. Silence passed by for a few minutes, your face was burried in the pillow, still feeling embarassed about the incident, "I-I dunno... why ask me..." Silence again. A few moments later, Gaster stood up of the bed, and opened the door, "Miss Y/N, i'll be doing some process & tracking for a while. Would you like to come with or...? I-it'll only take a while..." He was tripping on his own words, too. "O-oh i'll be staying here... just a while..." You said, still on the pillow. "Oh? Alright..." After that, he closed the door behind you and took one last look at you.

...

"UGHHHH, Y/N, WHY. ARE. YOU. SO. STUPID!?" You scolded yourself, and kept screaming, you rolled all over the bed until you fell onto the floor. THUD. you were making such noises, weren't you? Anyways, Gaster. He didn't leave at all, he was behind the door all the time. Laughing at you, and secretly spying, "How childish of you, Y/N... I really like that..." after that, he left the door, and screaming 'yes' in a low tone.
