Slender's Pov
I can't resist the chuckling that leaves my chest when Y/N becomes so nervous in her confession, it being easy enough to figure out where her thoughts were going.
"You steal my daughter from me, defy death to become my ideal partner, and now you're scared that I'm going to leave you broken hearted? You're a cruel woman," I tease with a laugh as I envelope Y/N in a tight hug. "I may be a monster, but I don't think I could ever be so cruel to abandon the woman of my affections and Sally's love."
"Just Sally's love?" Y/N questions, her gaze almost desperate when it finds me.
"Well she obviously holds affection and yearning for you, and when she's ready I have no doubt that she'll desire giving you the title of mother if you're willing," I explain, tilting my head to the side from the disappointment running through her eyes. Was she expecting something more?
"I would like it if she called me Sally," Y/N declares with a bright smile, no trace of the disappointment I saw earlier anywhere in her gaze. "Can we go back now? I'm sticky and crusty with blood."
"I'll take you to my room," I declare, lifting my blood soaked mate into my arms and teleporting her back to the mansion so she could shower.
Once Y/N is in the bathroom I go to some of the female creepypastas to gather clothes for her, making a mental note to let Trenderman get her new measurements so she would have better fitting outfits. She was taller in her new form and she would need the ability to let her tentacles rest comfortably without the restriction of clothes. After gathering the items I lay them out on the bed and change into a pair of pajama pants for the evening, my entire face going a dark red when Y/N exits the bathroom wearing one of my white shirts for coverage.
"Y-You know I gathered some d-dresses and such for you to wear. Where did you even get that one?" I question, having not seen any water on the floor so there was no way she procured it from the closet.
"It was in the hamper. I want to wear it," Y/N declares with a sweet smile as she walks over and crawls into the bed beside me. "Slender, thank you again for everything. I don't know what I would have done without you."
"It was only natural that I rescue you Y/N. I love you," I declare as I place a deep kiss on her lips, grunting in surprise when something warm touches his cheeks. "Y/N what's wrong?!"
"I'm sorry there's nothing wrong. I'm just so happy!" She hiccups, a bright smile on her lips as she wipes away her tears with giggles.
"Ngh, you're not over your human emotions yet. I don't understand crying from happiness," I complain with a sigh and pull Y/N into another kiss, gently pushing her down into the bed and pulling her form into my chest. "Let's get some rest."
"I love you Slender," Y/N says softly as her form rests against mine, my hand gently stroking her hair as her breath evens out into sleep.
"I love you too Y/N." I breathe quitely as I settle for rest as well.
