~~~~~Story + Time Skip to a Month Later~~~~~

I snuggled next to...air? Huh. Nightmare must've gotten up already. I closed my eyes again, hoping for some more sleep.

.........

Nah, I'll get some breakfast.

I got up and noticed my scarf was gone. I shrugged, I can find it later. I left the room and went downstairs. I drank a bottle of ketchup and went back to our room.

It was locked. I could've sworn I left it unlocked. I shrugged and felt Chara unpossess me and they stuck their head through the door. CHARA!!! Dude............ Chara came back into my mind and fell silent. G' night, wake me when the place burns down. Okay....? I heard a small 'click'. Go and see... Okay..?

Whatever I was expecting, it wasn't THIS.

~~~~~Lemon (Weird Sh!t) Starts here~~~~~

Nightmare was pumping his own member and moaning softly into my scarf. He seemed to be moaning my name. He heard me enter and turned his head quickly to me. He blushed deeply and stopped. I pretended I didn't see anything, turned, and walked out. I felt a bit of blood trickle down my face from my nose (hole).

*Whoosh*

I was teleported back to his room and I felt Nightmare kiss me. I started kissing back. He stopped, still a deep blue. "Wondering why I'm like this?" He asked me. I nodded. He never acted like this around me. "I'm going through heat~" He dragged out the word 'heat' and kissed me again, this time asking for entrance. I let him in, moaning into the kiss. He slid a tentacle down my pelvis and played with my already hard member. I moaned in pleasure. He separated from me and asked "You want to?" It sounded like an actual concern. He was referring to what happened a month ago. I never thought of that anymore, Nightmare didn't have to ask.

I didn't say anything as I striped down and pressed against Nightmare, feeling the wonderful warm sensation of him around me. He moaned loudly and pressed farther against me until my pelvis was inside of him. I moaned loudly as I felt myself come close. Nightmare screamed in pleasure as I came inside him. I panted, feeling worn out. Nightmare turned me over. "Get on your knees," He commanded. I did so. He sat, legs spread out, in front of me. I bent my head and sucked on his tip. Nightmare moaned and pushed my head farther down so I took in all of him. He bobbed my head up and down, making him moan. He moaned in pleasure again and came in my mouth, which I swallowed, licking some off the sides of my mouth.

He got up and pushed me onto my ribcage. He nipped at my neck until I let out a moan louder than the rest, telling him he found my sweet spot. He sucked and nipped at it, leaving a hickey there and moving to other places, leaving hickeys there too. He traced his fingers over my spine and around my pelvis, making me moan. "J-just f#ck me a-already," I moaned. Did I really just say that out loud?

"Happily~" Nightmare cooed. He pushed his tip into me and I was already screaming in pleasure. He pushed in farther, making my screams escalate. He began thrusting in and out at a very fast pace, and soon came inside me. He collapsed onto me, as tired as I was.

Our souls appeared over our heads, making us look up. Our souls squeezed against the other, making Nightmare and I moan in pleasure. The feeling was like a very tight and cozy hug, but a lot better. After a while our souls separated and re-entered our bodies. Nightmare sat up and my soul appeared in front of him. He licked it and squeezed it gently, making me moan in pleasure. He stopped and my soul re-entered me.

Nightmare hugged my tightly, making me enter him by a few inches, making us moan softly.

We soon fell asleep. . .

~~~~~Lemon Over~~~~~[600+ Words]

I awoke the next day quite tired. Chara was still in my mind, asleep. I teleported into the bathroom, no clothes on. I held onto the counter for balance since my legs weren't working. I looked in the mirror but something about me was different. It was VERY noticeable. My abdomen had a sort of  blue magic barrier around it, making what looked like a stomach. As to what was IN the stomach...

It was a tiny soul.

It took all of my willpower not to scream. CHARA!!! Ugh... I'm tired...let me sle- HOLT SH!T!! They shouted the last part. WHAT THE HELL IS THAT!?!? I THINK IT'S A CHILD! BUT YOU'RE A GUY!! I KNOW!! Maybe it's because...since we share a soul...and you are gender neutral.... ...What are you getting at??? You are then BOTH genders, so you have girl and guy soul parts...so BABY! BUT WHY!??! I CAN'T CONTROL IT!! Chara stopped talking and went to sleep again. Hopefully this is some messed up dream... Nope...

I stepped into the bathtub and filled it with cool water, it lapped against the magic womb. The soul was only a few centimeters wide, an adult soul was a few inches. I laid my head back against the tub. I soon got out, which was quite hard since I couldn't feel my legs. I got dressed and teleported back onto the bed, where Nightmare was still asleep.

Ohhh...it's gonna be fun to tell him this....

I shook him slightly to wake him up. "Nghhh....5 more minutes...." He fell asleep again. I poked him. He didn't stir. Use water. No! Hehe... I thought of how to wake him up. I kissed him.

Yeah, he's awake now.

"Nightmare~ I have some news~" I told him.

"Good or bad?" He asked.

"It depends how you take it," I answered.

"Okay...tell me then!" He was curious.

I did jazz hands as I said. "I'M PREGNENT!!!"

~~~~~End of Chapter 9~~~~~2 chapters in one day? 2 lemons in one day? Nice. Hope you like kids. *Jazz hands*
