_duckiepotato_ ur an asshole

Olive POV

As I got into bed with Sans, he gave me a bracelet. I loved it and I started to make out with him. I was on his lap. He started to get kinda touchy, and that resulted with our shirts off, I still had a bra though.
He would grab my ass and play with my breasts as I would grind him. Eventually, he was biting my neck and licking it, leaving behind blue ectoplasmic saliva.
I could feel his erection on my crotch.
About 5 minutes later, my bra was off. I had nothing on except for my underwear. His pants were off and Sans was naked.
"I didn't know we would actually do this, heh.." Sans said, blushing.
"Yeah, me neither."
I started to bite and suck on his rib cage and worked my way up to his skull. I kissed him again, and my panties were off. He put on a condom. I sat on his pelvis, and he was now inside of me.
"Ah... rggh.." I moaned.
Sans seemed to be a professional at sexual pleasure, I was so inexperienced. This proved he was no virgin.
He thrusted slowly, and I kept kissing him, not knowing what else to do.
"Here, ever heard of a blow job?" Sans asked.
"Well, yeah of course, I've never done one though..." I said.
"Try your best.." He said, pulling his member out of me and by my mouth. I opened up and swirled my tongue around the tip, tasting both him and me.
"Fuuuck... your so soft..." He said, rubbing my ass.
I kept sucking until I heard a knock on the door.
Sans but his pajama bottoms back on and ran to the door. I managed to get my pants and bra back on before Sans answered the door.
"Oh dear me, sorry Olive.." Mettaton apologized, seeing me without a shirt.
"What do ya want..?" Sans asked.
"S-sans, do I have permission to make.. um... love to your brother?" Mettaton asked.
"Bring Pap over."
"Ok.."
Mettaton got Papyrus.
"Yes, Sans?"
"Ya boyfriend asked me if you two could make love, and I wanted to know how much you love him."
"I love him very much, Sans! He means the world to me! I'm all grown up now, and I like being in a relationship with sexual pleasure." Papyrus explained.
Sans hugged Papyrus. I got my shirt back on and told Sans I was gonna talk to Mettaton for a sec.
I pulled him to the side.
"How's it going with you and him?" I asked.
"Very well! I love Papyrus very much! He is my soulmate! It's like you and Sans, you two are perfect for each other!"
"Who told you to ask Sans before you did the deed with Pap?"
"Well, Papyrus was starting to get very touchy amd flirty and romantic with me, but before I took things too far, I wanted to make sure that Sans was ok with all of this."
"Well, I'm sure Sans will agree at some point."
I hugged Mettaton, and comforted him, knowing that Mettaton felt like he was being prevented from loving the person he loved the most. Mettaton started to tear up. I tried hard to comfort him  and tell him that he is the most gorgeous, amazing, talented, robot in all the underground.
"Thank you, darling.. I-it means a lot.."
Mettaton got up and walked over. Mettaton was very happy all the sudden when Sans said something to them. Sans hugged his brother, and Pap picked him up and squeezed him.
"Ok,ok."
"Thank you brother!!" Papyrus skipped into their room with Mettaton.
Sans and I fell asleep, hugging tightly.
