NOTE: Olive is 23 and Sans is 24. Everyone is 21+ and yes I did make that art for the sake of this chapter.

Olive POV

Just a normal day. Waking up by the sound of banana pounding as loud as she can on the door, eating some cereal, and heading off to the skelebro's house. I didn't think of the two brothers of anything more than friends. I didn't feel like walking the 10 minute walk so I asked Undyne (She got a part time job as an Uber) to drive me there. Once we arrived, I gave her the swimsuit she had left at Banana and I's apartment, and knocked on the door to the house. Before I could even knock twice, Papyrus opened the door for me.
"OH, SALUTATIONS OLIVIA!!!" Yelled the tall skeleton exited.
"W'sup Pap? And you can call me Olive for the thousandth time."
"OH, EXCUSE ME! WOULD YOU CARE FOR SOME SPAGHETTI?"
"Why not?" He walked me inside and gave me a bole of spaghetti. Despite how sweet and harmless Papyrus is, his spaghetti was always the opposite.
"Oh, Heya, Liv."
"Hello, Sans. How was the lab yesterday?"
"I wouldn't say lab anymore, I would say staying up, eating ramen and watching anime with Dr. Alphys. But it was good." Said the short skeleton.
"Pffffft!! Once you guys are done with Mew Mew Kissy Cutie you should watch Kakeguru. It's my favorite. Or maybe 7 deadly sins, or Danganrompa."
"Watched Em' all. They were good, though.
"WHAT THE HELL?!" I said surprised.
"You really are always a step ahead of me." I said.
"Hehehe!" He said and blushed. I thought he liked Frisk?
"Heh.." Odd.
You know, I never had feelings for Sans, but he is a cutie. I might fall for him someday. Actually, nah. That would be pretty unlikely.

Sans POV

Dammit! I'm blushing!! She noticed too, so now she might be getting on to me.
"Ehem... uh... I uh- I GOTTA GO TO GRILLBZ." I ran away to Grillby's and talked to Grillby about what happened.
"Ohhhhh god..."
"Sans? What is troubling you?" Said Grillby.
"I think Olive might know about my feelings for her."
"Just tell her, give her a present and kiss her or somethin'." Said Dogamy
"Yeah!" Dogaressa said.
"F-fine. But first, I'll take a shot of ketchup."
"There we go buddy!!" Dogamy cheered.
I walked to the shop and got some stuff for Olive, such as chocolate chip cookies, and Takis. That's what I'm pretty sure she can't live without. Anyway, I got the things and walked home. I gave her the stuff and she thanked me. But this is the best part. Right after I gave it to her, before she thanked me, she smiled and winked. YEEEEEESSSS!!!!

Olive POV

Ok, forget what I said before about not falling for Sans. Christ, he gave me TAKIS. T A K I S. I showed him I liked him back by winking. But right after I winked and thanked him he smiled a lot bigger, blushed a really deep blue, and ran up to his room. Actually, not running. More like a fast waddle. Like I said, he's a cutie. Anyway, later that night Banana and Mel set up a little horror movie party thingy. The movie was TERRIFYING to me but luckily, Sans offered to come over to the apartment and sleep with me for comfort. But after walking back together with Banana, we got a little drunk. I don't remember much, but I do remember the following: Sans and I stayed up watching John Mulaney until 3 am, we invited everyone over to party, we got even more drunk, and we made out. I don't know what to think. But now I just woke up, in a bed that's not mine. It was Sans'. WHAT DID I DO?!!! I was only wearing a bra and sweatpants that were thankfully mine, and yes, the bra was also mine. My shirt was on the pillow, so maybe it had just slipped off at night accidentally. I peek over my shoulder and see Sans looking at me. He looked just as confused as I was.
"Did we... have sex last night?" He asked.
"I don't think so, but we made out." I said while I put my shirt back on. Wait. That isn't my shirt! It's his!
"O-oh wait.. this is yours... here... sorry..." I said while handing it back to him.
"Nah, it's fine. Keep it. It's too small for me now anyway. Not to mention you only have a bra on, so you should probably put on somethin' anyway."
Ok, maybe we did have sex. He was only wearing boxers. Wait no.. I think we maybe just went swimming... I hope. I put on his shirt, and just hugged him and cuddled him for about an hour. I know he is a skeleton, but he is nice and warm to the touch.
