Sans AUs x Child Reader OneShots

CrossMare x Son/Daughter Reader [part 1]

Your the daughter/son of a sancest ship Cross x Corrupted Nightmare. You're a skeleton like them. The picture above is what you look like but you can change the look if you don't like it.

By the way the way I ship them is that Cross would be the mother figure and Nightmare would be the father figure

This is the day they've been thinking of making you.

________________

It was just like any other day in Nightmare's castle. The bad sanses were just chilling in the living room while Cross and Nightmare were in their bedroom talking about having a child and how it would nice to have another addition to the team since their powers are a little more harmful than the others' and them combined would break havock really badly which would help them move from destroying one au to another faster. After they finished talking about it they finally decided to make a child that's half corrupted like Nightmare and half like Cross.

They've been now in bed and were to start the process of making out.

"Ready?" Nightmare said with the lower voice and a grin.

"U- m yeah I guess so." Cross replied still unsure of this whole thing but if he said something about not accepting Nightmare would not be so nice to him afterwards.

He didn't want that to happen so he accepted.

They both started taking their clothes off until they were both completely naked.

Cross was laying on the bed waiting for what Nightmare would do next.

"Alright I'm gonna put my tentacles inside you. Is that ok with you?" Nightmare said wanting to know if his mate was comfortable with what he was doing.

"Y-Yeah sure..." Cross answered not feeling that comfortable with what was going to happen.

Nightmare: "If it hurts tell me and I'll stop"

Cross: "um mhm."

Nightmare slowly slid his tentacles inside Cross and started thrusting them at a fast pace. Cross let out a moan and a gasp, gripping the bedsheets. Nightmare thrusted faster as Cross moaned louder and louder.

"A-AH NIGHTMARE PLEASE MORE!" Cross pleaded as Nightmare thrusted deeper and deeper.

Nightmare thrusted more deeper causing Cross to become more louder. He was almost ready to cum.

Nightmare: "I'm almost there Cross~"

Cross: "Please don't stop!"

Nightmare: "As you wish~"

Nightmare thrusted faster and faster making Cross scream.

Cross: "F-FUCK! NIGHTMARE! IM GONNA CUM!"

Nightmare: "Same here."

Nightmare thrusted faster until Cross screamed out his name cumming on the bedsheets. He panted, sweat and tears running down his skull. Nightmare came shortly after.

Nightmare: "That was great. I enjoyed it a lot. How about you?"

Cross: "Y-Yeah it was."
