"Okay, Frisk, pass the plastic wrap please."

     Frisk giggled, passing Chara the small box. Frisk, Chara and Asriel were alone in the house with Sans, who was downstairs doing who knows what. The others had gone to the store, so now was the perfect time for their revenge. Chara finished and stepped back, admiring her handiwork.

     Asriel shook his head, "This is so stupid."

     "Yes, but you agreed to it. Besides, sometimes the simplest things are the funniest. Okay, Frisk, when I say 'now' call for him. Azzi, get the foil."

     Frisk watched as they crouched behind the open basement door. Plastic wrap shimmered in the doorframe, nearly invisible.

     "Now!"

     Frisk dropped a plastic bowl and let out a ear splitting screech,"Sans! Help!"

     Thumping could be heard from the basement, and Sans appeared, two feet off the ground. He jumped up, looking around.

     "What happened?"

     "I thought,"she watched Asriel and Chara dart downstairs,"I thought I saw a spider. But I guess I didn't."

"um, okay? im gonna go now."

"Wait! Um, I need to ask you something."

"well, spit it out. cat got your tongue?"

"I, um, I was wondering how, um, you and Jojo were, uh, getting along. I haven't seen her in a while."

"oh, she just had to go help one of her friends. look, ive gotta go, talk to you later."

Frisk panicked, they needed more time!

"I have another question. Why... Why don't you like Chara?"

Sans sighed,"i just, have a bad feeling about her."

"But she hasn't done anything! You really ought to apologize to her, she just wants to be friends."

He snorted,"yeah, likely story. i will not let my guard down."

"Why do you hate her! She has done nothing to hurt you!"

Sans didn't answer, and Frisk read a text from Chara.

Hey, we're done, let him come down. Also, follow him, you'll want to see this. :*

"Whatever. Go ahead back to your room. Sorry for wasting your time. I just thought you were kinder than this."

Sans got up slowly, obviously too flustered to teleport. Frisk swiftly opened the camera app and began videoing. Sans stopped in the doorway, smirking. He reached out and pulled the plastic wrap off the opening. Frisk frowned, and it we her turn to be flustered. They walked down the stairs, and Frisk had to stifle a laugh as they entered his room.

     Asriel and Chara had managed to wrap everything not held down in aluminum foil. Sans gaped, speechless.

     "Well,"Chara began,"I guess since you're not wrapped up at the moment, our plan was foiled."

     Sans laughed once, smiling.

     "oh, all right. you got me. i guess ill try to make peace with you guys."

     "No, that's not enough. Apologize to them. Now."

     "ugh, fine. chara, sorry for blaming you for stuff you didn't do."

     She didn't answer, just stared at the ground.

     "and, sorry for thinking that the flower was you asriel."

     He nodded stiffly. Sans sighed, looking at them.

     "are you going to help me clean this or...?"

     "Ha!"

---

Frisk sighed happily, playing with Chara's hair. It was about 9:30 at nigh and they were laying in bed. Everyone else was sleeping, exhausted from Toriel dragging them around several hundred stores, or, in Sans's case, unwrapping several layers of aluminum foil off of each of his socks.

She ran her fingernails gently over Chara's shoulder, who shuddered.

"Mmm, that feels good."

Frisk set down the book she was reading, using both hand to scratch Chara's arms. She snuggled closer, goosebumps rising. Frisk leaned forward and kissed her, making her blush, but Chara kissed back nonetheless.

She rubbed Chara's waist, earning a little squeak. Frisk smirked, pulling out of the kiss, and began kissing her neck,trailing all the way up to her ear. Chara gasped, then giggled, pointing above Frisk.

"Your soul is showing."

Sure enough, a half heart hovered above her back. Frisk noticed the same right above Chara. What she didn't notice, though, was that both of their half souls were a little larger than last time. Of course, being caught in the moment, who would notice such trivial things?

     She brought Chara's soul to her hands, stroking it. She flared red, biting her lip.

     "Geez, Frisk."

     Frisk squeezed it slightly, experimenting. It's texture was strange, soft and smooth, firm yet giving. Even the jagged edges from the split were incredibly soft. She had never felt her soul before, her hand would just pass through it anytime she tried.

     Chara was a mess. She gasped a breath, and pulled her soul back.

     "Th-that's... Wow. Y-your turn."

     She caressed Frisk's soul, still panting slightly. She felt a warmth envelope her body and a tingling feeling in her chest. The feeling grew and she unintentionally let out a moan. She quickly quieted it, not wanting to wake anyone. Chara let go of her soul, face glowing. She ducked in, catching Frisk's lips with her own.

     They deepened the kiss, leaning into each other. Frisk flicked her tongue lightly against Chara's lips, asking permission. She was granted, and the two fought for dominance. Frisk quickly won, but she sensed that Chara had let her be in control.

     She explored every inch of her mouth, relishing every second of it. Chara whimpered, a sound that alerted Frisk to the tight sensation in her chest. She pulled away, allowing both of them room to breathe. They panted, and both flushed a dark red.

     Chara smiled, eyes sparkling with both love and lust. Frisk smiled back, eyes glittering with similar emotions. Neither noticed their souls getting closer and closer together. They connected again, seeming to be two puzzle pieces that fit perfectly together.

     Chara pulled them down to where they were no longer sitting up. Frisk ran her hand slowly up her side and under her shirt. She stopped, resting where her fingertips were brushing in between her shoulder blades. It was Chara's turn to explore Frisk's mouth, and she did so eagerly.

     The two broke apart, the same expression of love on both of their faces. They froze as the hallway floorboards creaked and the door was pushed open. Toriel stood in the doorway.

     "Oh! S-sorry, my children. I couldn't sleep, so I went to do some baking, and I noticed your light was on. I didn't know if you fell asleep with it on, or..." She trailed off, looking throughly embarrassed,"I'll, go now."

     Chara groaned as the door shut, but Frisk wasn't troubled by Toriel busting in. Everyone knew that they were together, why should it matter if they kissed? Frisk's only annoyance was that her mother had ruined the moment. Oh well, she thought, snuggling closer to Chara, at least there'll be pie for breakfast.

I. Bet. You. Didn't. Expect. There. To. Be. A. Slight. Smuty. In. This. Chapter. This was very interesting to write because I've never written anything passed kissing. Meh it was fun. So sorry for not updating yesterday! I got really busy and had no time. Good news, I might have wifi while driving to my vacation destination, if my mom allows. So, cross your fingers! Also I love Frisk's shirt in the picture.
