"Visit"

(P.s this is 3rd person view now, deal with it)

"I'LL GET IT!" said sans from in the living room. As he opens the door, he sees Alphys & Undyne standing outside with kind of a 'we know something we shouldn't' look on their faces. "What's up, guy's?" sans asked, but all they both said was 'nothing much'. They sat on the couch and started whispering words to each other, papyrus than walked out of his room rubbing the top of his skull, trying to figure out if the "things" from last night were real or not. "I'm making breakfast, do you guys want any thing?" says sans, trying to break the awkward silence, but Alphys & Undyne just looked at him in a judging way than went back to their so called 'secret' conversation.

(Y/n) rub your eye's and stretched before going downstairs for breakfast. Walking down the stairs, you noticed that Alphys & Undyne were on the couch, and beaming (y/n) say "Hey! What brings 'Alphdyne' here at this time of day?". They look at (y/n) scared for a second then Undyne replied "Well, we j-just wanted to drop by h-here and s-see how everyth-thing is doing. Right Alphys?" "Yeah" she responds "It's not like we had a hidden camera we need to look for or anything!!". Undyne than hit Alphys in the back of the head, making her yelp a bit silently cursing. "What.Camera?!?!" Both the Skele-bros and (y/n) asked "Ummmmm, nothing." they say slowly inching their way to the door. Papyrus and Sans than block the door, making sure they don't leave.

"Explanation.NOW." (Y/n) demanded. "Well we had a camera attached to a certain part of Sans's room one night a day before our double date, so Alphys and me had to make up an excuse to part ways with you guys by saying we're going to have a 'private date'." "so what?" (y/n) responded "Well," continued Undyne "I had to connect to the camera and, well, l-l-let's just say me and Alphys were surprise that you guys had a fun 'private date'." Sans, papyrus, and (y/n) are blushing hard at the fact that there 1. Was a camera in the room and they didn't see it & 2. Alphys, Captain of the royal guard & Undyne, Royal scientist, watched two skeletons and a human having sex.

"Well, what are you waiting for? Find the camera and delete the evidence of the things that happened last night!" say papyrus, leading them to sans's room. "Okay." is all they said before entering the room. A few hours past before they found the camera, "I've completely terminated every second on the camera of the things that happened only on that night." says Undyne filled with a mix of shame being over powered by pride. "Thank you so much." sans says "Your welcome, little squirt." says Undyne in a playful manner, giving his skull a nuggie making him let out a little laugh "And by the way, you guys made quite the mess on the floor." The poor blushing blueberry ran to his room to clean it, (y/n) running after him to help out.

"Just one last thing before you guys go." says Papyrus, lighting a cigarette "What is it?" Alphdyne asked (And yes I know the ship and I'm just trying to be a lazy bones, but get off my back 'bout it). Papyrus's right eye socket then glowed a fire orange color and he said in a voice so serious and scary "TELL.NO.ONE!!" shaking their heads, he let them leave.
