Undertale one shots

sans x reader fluff

This is about where when the monsters to on the suffice and Chara lives with them.
One day Chara thought it was a good idea to put male V.I.A.G.R.A in sanses ketchup without anyone seeing since you and sans are dating (if you don't know what V.I.A.G.R.A is it basically a pill that makes people horny AF).

You and sans were on the couch bored since everyone else in the house was busy. Sans was drinking his ketchup will you were watching MTT.

Time skip

Sans started to feel horny so without you knowing he started to a little closer so you until he started so kiss you neck(?), "Huh? Sans why are you kissing me all of a sudden?"
" no reason ~" he answered with a deep/ sexy voice that will make any girl melt, he still kept on kissing you neck. Sans got on your lap while putting arms around your waist and grinding agents you,that's when you knew what he was trying to do "sans come on I'm not in the mood" you said while trying to push him off of you but he would not move," aww come on baby~ I'm horny"
"Papyrus and the others will probably come back soon"
"So? It will just be a quicky ~" he answered,he lifted up your shirt/tank top/whatever your wearing to cover your bra and rubbed the waist. He started to lick/bite your neck and grind even harder agents you.
"Sans no. I'm not in the mood,I'm still in pain after last night's" you said to him getting him off your neck,
"Hmmmm but I'm horny~ I need you"
" well to bad " he started to his you on the lips and his tounge started to dance with yours, "sans *kiss* come on *kiss stop"
" come on baby girl. You know you want to~"
"No I don't stop"

He nuzzled your neck and put his hands South to your butt, he ripped your shirt/tank top/whatever your wearing to come cover your bra, "SANS! come on this is not funny stop!" You commanded but you would not stop ,he just had a shit eating grin and licked your neck again "*moan* ok ok fine *moan* j-just stop" and the rest is up to your imagination ;).
