Y/n's POV
              I hate these days! My heat days... it's 3 days! And it sucks! I feel the need to grind on something and it hurts. Luckily, Sans and Frisk are still out on a trip and G might not be home. I go downstairs to see G on the couch. He was just staring at the blank TV that then loaded to the funny animals TV show that I love. I sit next to him on the couch and rest my head on the side of him. Maybe I could just sleep on him like I usually do and then if he's asleep I could... no that's rude.

              But... hmmmm? I don't know!! I turned his back to the arm of the couch and I crawled on top of him and rested my head on his chest. When he wasn't paying attention to me I grinded on him once. I'm such a bad girl... but it feels so good! I noticed he looked at me then looked back at the TV I grinded on him again. I'm gonna die for this but it's better than being in pain! When I saw he wasn't paying attention I did it again. But this time he teleported us to his room and closed his eye sockets probably gonna try to take a nap or something. I grinded on him another time, but this time harder. I stopped for a second to see if he woke up. "He's definitely going to kill me for this..." I mumbled.

G's POV
              Shit Y/n! Is she on her heat today? I know I'm on mine and, shit! I thought she wasn't home! Is she grinding on me? I opened one of my eye sockets time to time to see what she was doing. Yep definitely grinding. She's gonna get hurt if she continues doing this. "He's definitely going to kill me for this..." I heard her mumble. She started grinding harder and it felt so nice.

              I grabbed her waist and pulled her closer to me. "H-huh?!" She said, shocked at my sudden movement. I flipped her onto the bed so she was facing me and I was on top of her. I started grinding on her myself. "You thought you'd get away with it?" I asked teasingly. She only whimpered in response. "How long does it last?" I asked "uhh wh-what do y-you m-mean?" She asked "how long does your heat last?" I asked "th-three d-days." She stuttered.

              "Good." I said. I kissed her roughly and passionately. I bit her lip asking for access but she denied teasingly. I growled and squeezed her ass causing her to gasp and for me to slip my tongue into her mouth. My tongue explored every inch of her mouth. I pulled away so she could breath. She was blushing and softly panting. "I want to feel you, I want to taste you, I want to touch you!" I said going for her neck.

              I searched for her weak point and abused it when I found it. When I found it she shuddered and let out a shaky moan, but quickly covered her mouth. I smirked and continued to abuse it. Her moans only got louder and her hand couldn't cover the sound. While I was doing that I snaked my hands to the edge of her shirt and tugged at it asking for permission. She nodded and I pulled it off her. I started making out with her again so I could snake my hands to her bra clip. When I unclipped it she quickly covered herself. I moved her hands and rested my skull on her breasts and said "mine."

              I heard her giggle then I licked her breast causing her to shake and let out a breathy moan. I continued messing with her then I was able to slip off her pants. Next I was able to slide off her panties then undress myself. I started grinding on her, teasing her. I moved down to her womanhood and cleaned her out. Causing her to moan. I placed my member at her entrance and looked at her begging cat eyes. My heat caused it to hurt for not doing this part already so I almost slammed into her.

              I began thrusting slowly causing her to want more. "F-faster!" She stuttered. I went a little faster "n-no f-faster!" She said. I went as fast as I could she moaned at every slightest movement I made. "I-I'm g-gonna cum!" She said "m-me too!" I said before we both cummed. I cleaned her out again and I pulled the blankets over us before we both passed out.

(Finally! I finished! Not the book but this chapter!)
