" Nightmare were are you " I said as I walked around the castle, Nightmare has been acting wearied lately, like every time he saw me he would blush madly and run the other way and lock himself in his room, I was getting to the bottom of this.

I turn the corner but stopped as I saw Killer sans smiling, he soon saw me and walked over. " Hey Cross " "Hey killer. . . What are you doing" " Oh nothing " he said as he walked away smiling.

'What's with that guy' I thought as I walked to nightmare door,I was about to knock, until I heard some thing. ' Is that moaning' I thought as I put my skull to the door "Ahhh~ Cross. . . Ahhh" I heard him say witch made me blush madly.

Chara my other side came beside me " what in the world!!!! why is Nightmare screaming your name " I looked at Chara as I was blushing " Oh don't tell me you're getting turned on. . . you know what i'm out see you when your no longer getting turned on " he said as she went away.

I rolled my eyes as I continued to listen to Nightmare masturbating as he thought to me, thats when I kindove pushed the door opened. The door flew opened making me fall and scaring nightmare as he screamed " CROSS W-WHAT ARE YOU DOING " he screamed as he covered his member with a pillow.

~Nightmare pro and a week earlier ~

' Shit no please no don't tell me that i'm in heat ' I thought as I got really heated ' maybe it'll just go away' I then saw cross coming twords me, he no longer calls me Senpia witch I hate saying it but I really do miss him doing that.But why he's no longer calls me that is because. . . he no longer was in love with me.

'Stupid brother ! Look what you made him do !!!! You knew that I had feelings for him' I thought as I sat back. I sighed as i got up and went to the kitchen to get something to eat and also to drown my sorrow , I turned around and saw Cross walking alone 'why is he alone were's my brother " I growled as I thought about my brother.

I went up to Cross with the bottle of Vadca in my hands " Hey Cross were's my brother " Cross looked at me,a pit of sadness was in his eyes "I told him about how I felt, but he. . . He told me that he and Ink were already a couple and were also engaged " he said as he looked away from me tears running down his face.

My eyes lit up as I started to blush madly ' on no shit ' I said as I ran to my room locking myself in "lets get this over with".

~ Back to present~

I started to blush madly as I looked at Cross, Cross blushed back. I got off the bed, closed and locked the door, then looked back at Cross as I pulled on his scarf making us kiss" Hmmmm!!!!!!!!!!!!" he said as he pulled me closer.

We stayed like that for what felt like eternity but we did pull away, I smiled at him as I pushed him on my bed kissed him again and started to take off his pants. Pulling away from the kiss I saw his member I blushed even more as i aliened myself with his enterence and started to push in.

~Cross pro~

'Oh Asgore this feel's Incredible i never felt like this. . . I never want this to end' I thought as he pushed his member into me.He started to trusted as I screamed out in pleasure, I bucked my hips, drool, and continued to scream.

But I got the slight feeling that we were being watched but I pushed it away " N-Nightmare. . . Senpia " I screamed as I bucked my hips again. After I had said that I felt him going faster and harder witch only made me scream out more " SENPIE AHHHH~ THIS FEELS TOO GOOD ".

He soon hit my sweat spot making made my eyes shrink and screamed very loud, probably the whole multiverse heard it, but he put one of his tenticales in my mouth " Shhhh not so loud " he said as he continued to pound.

I could feel my climax and it was coming fast " S-Senpie i'm about to-" "nope" he said putting one of his tenticals ferm on my member making it impossible for me to cum " B-but Senpie "I said as I looked at him begging him for me to cum " Nope not going to let you ".

I whimpered as I continued to scream in pleasure, " Shit Cross I'm about to cum " he said as he as he pounded into me as hard as he could before cum into me. He took his tentical off of my member witch I cam hard.

Once I was done Nightmare slid out of me as some of his semon spilled out, he picked me up and placed me sideways on the bed as he got on the other side of the bed. He intertwined our hands together as he kissed my cheek, I kissed back as we both fell asleep.

~Killers pro~

" Oh god yes " he takes a picture of them fucking "this is my wall paper now " he said as he put it for both and he put his phone back into his pocket and walked away from the door.
