When you were walking into your room... You see Fell Sans standing alone in hallway and you invited him into your room. Surprisingly, he agreed and he entered your room. It was clean... and he looked at you as he sat on chair and looked at you like he gonna do serious talk to you even if he wasn't doing it... however when you got close to him... By instinct you sit on his lap... And to make it worse... You leaned your back on him... like he is pillow on the bed... However he got angry or rather annoyed... as he wraps his arms around you, pinning your body against him in tight cuddle. He kept the eye contact with you, he won't let you out of his sight and to make sure you wouldn't move from your spot, he wraps his legs around yours, locking you in place, forcing you to have no choice but look at him. As he huffs in annoyance. As he speaks in low, yet annoyed tone.

Canon Fell Sans: Happy? I hope, so...

He spoke as he tightens his embrace before looking at you, now being quite pissed. He clearly didn't like the fact you sat on his lap... and even less the fact you leaned on his chest, like he is your pillow...

Canon Fell Sans: You can't help yourself, can you? You just had to act like I am a goddamned pillow... You know what?

He then teleports onto the bed with you in his arms as he lays onto the bed and rolls you to face him as he tightens hugs.

He pins you against his body very tightly, laying besides you as he glares at you, his face now being very close to yours and you realize how small (and powerless) are you next to him. He gives you a pissed look as he speaks... trying not to look embarrassed as well

Canon Fell Sans: Now you're trapped... you're not going anywhere till... I gonna be satisfied... Now, Goodnight.

He then squeezes you against his body... He's kinda sweaty despite him being a skeleton... He is probably sweaty from His own jacket or just his Strong Emotion... You could hear his fast heartbeat coming from his Soul... it's so Strong...
