Your P.O.V

You walk out of Grillbys,it didn't go as well as you suspected you didn't really care anyways,you kept walking,heading for San's house.The snow crunches beneath your feet,you let out a long sigh,your breath being revealed before you.You keep going and finally reach the house and walk inside,"I'm home!",you call,there's no answer,you figure Papyrus is either in his torture room or out still but he wasn't at Grillbys,the jerk must be at Mettatons."Sans?",you call.You don't hear anything,there's suddenly loud moaning,you take off your jacket then head upstairs,it's coming from San's room.You tilt your head and open the door,you stop and a dark red blush spreads across your face.Sans was laying there on his bed,his member sticking out of his pants,it was huge and glowing red,he stops frozen and sees you.You stand there still in the doorway.

San's P.O.V

Shit,(Y/N).Instead of hiding and quickly covering up I growl and use my magic and slam the door shut,I use my magic and pull her up to me,"Don't you ever knock?!",I shout,she stares at me wide eyed still.Although I could quickly feel the blush creeping onto my face,she had come home earlier than I thought.My member was still sticking out,I knew it and the sight of her body was giving me a serious boner.She was blushing a dark red as we stared at each other. "You will not tell Papyrus about this or else",I almost growled,she nodded quickly,I had scared her,good.She suddenly leaned in and kissed me on the lips (Teeth?). My blush and hers turned darker.I relaxed enough and my magic released her,dropping her delicately on the bed,she kissed me still and pretty soon I kissed back,I felt her hand creeping down my chest near by member.

Your P.O.V

My hand moved down as if against my free will,I didn't wanna stop and I wouldn't,I reached his member and ran a fingertip over the top,he moaned against my lips,I slide my hand down it then started to move up and down his member with my hand,he moaned a little louder.I pulled back and pushed him down fully,I went up and kissed him again but this time he flipped and was on top,he kissed down my neck and soon found my sweet spot and bit it,I moaned and he bit harder,I could feel the liquid running down my shoulder as he pulled my shirt and bra off,blood.He threw them to the floor,then continued to kiss my neck,I kept moaning.He moved down and played around with my breasts,I moaned again.He was licking circles around my nipples.He suddenly pulled off my pants and underwear,wasting no time.He threw them to the floor then looked at me,he then rammed inside me,I bit back a scream.He started to thrust back and forth hard and fast,I screamed a little but they were soon turned into loud moans of pleasure.He kept going,I was moaning loud,he was kissing and biting my sweet spot as he did."S-Sans....I'm gonna cum....",I moaned.He went his fastest then the knot in her stomach finally released as she came,Sans did right after her,he pulled out and layed next to her.

Nobody's P.O.V

Sans layed next to (Y/N) panting and out of breath.(Y/N) was catching her breath then Sans wrapped his arms around her."I love you (Y/N)",He says."I love you too Sans",(Y/N) says."Goodnight (Y/N)",Sans says."Goodnight Sans", (Y/N) says then they both fall asleep under the covers.

So I hoped you liked that story,there's more coming it's just that with school and everything my free time can be taken up,which Sans would you like next?Comment below.
