Hi everyone! Now before this starts I shall say, I was begged to do this and I promised so yeah let's ruin someone's innocents now shall we?
3rd Person Pov
You were currently sitting on Sans' bed with him rubbing your f/c cat ear. You leaned into his touch more and more, purring crazily. Your f/c tail moved from side to side slowly in pleasure. You then felt something not in your stomach. You growled in pain. "Y/n are you okay?" Sans asked worriedly. You nodded quickly running to the bathroom and looking into the mirror. You looked closely at your eyes to see their color have changed from e/c to purple and your pupils to hearts. Your breathing hitched. You growled in anger lashing your tail.
Your Pov
I growled. I don't wanna go through heat yet! Mother Nature you bitch!!! I slowly started making my way back to Sans' room. "Hey Y/n what's wrong?" Sans asked. "Oh n-nothing S-Sans!" I stutter. "Y/n your lying, you always stutter when your lying." He growled. "F-Fine! We nekos go through a thing every two years." I say sitting by him. "What is this 'thing' and what does it do?" He asked. "The 'thing' is called heat. It's when we find a mate and breed, I guess. I still don't have a mate so I have to live with it until I do." I answer. "Ohhh, so like what Papyrus told me." Sans says. I flick my ears in surprise. "He told you?" I ask questionably. "Yeah, he says that when you love someone very much you do 'things'." He says. "Wow....um." I had no words. Papyrus already told him. So, the innocent sinna bun isn't so innocent after all. "Umm Y/n," I turn my head to Sans. "Yes?" I ask tilting my head to the side. "Umm I-I l-love y-you." He says quietly. "I live you to." I say softly. He then kisses me. I immediately kiss back.
⚠️⚠️LEMON STARTS HERE⚠️⚠️
Sans then pins me onto his bed and breaks the kiss. My tail wraps around his waist slinking around. He then kisses me again as I pull him close. I then feel something on my left thigh. I ignore it though. We break the kiss as I begin taking off my shirt. I then kiss him. He breaks the kiss and starts to trail down to my neck trying to find my sweet spot. When he finally found I began to moan. He then began to suck and bite at the spot causing my moans to become louder. He then stopped and took off his shirt showing his rib cage causing me to blush. He then kicks off his boots and comes back to me. I then pull him into another kiss as he begins to take his pants off revealing some shorts of some kind. Though I didn't notice that he was unclipping my bra. He then started to massage my breast getting some moans from moans from me. I then began to rub his ribs with my tail. My ears flicked around. Sans then began to take off my pants. I let him do what he wanted not caring about it now. Sans then began to remove my panties, the cold air chilled me but I paid no mind. Sans then began to remove his shorts revealing his member. I stared in awe. He then climbed on me. "Please do it." I whined. He slowly entered me. Pain was all I could feel. I whine a bit. "A-Are you okay? Should I stop?" He asked worriedly. "N-No just w-wait." I said. After about a minute the pain turned into pleasure. "Please continue." I slurred a bit. He slowly started thrusting into me, by now we were both a moaning mess. He was thrusting hard and fast. "S-Sans I'm gonna cum!" I cried. "M-Me too." He said. I then felt a hot liquid enter me. He then disconnected from me. I lied there panting, him doing the same thing beside me. "T-Thanks Sans." I smiled. "No problem, it was fun~" He panted. I slowly got up and got dressed, Sans doing the same.
⚠️⚠️LEMON OVER⚠️⚠️
I then felt arms slither around my waist. "I love you Y/n~" Sans said and gave me a butterfly kiss on my cheek. "I love you to Sans." I sang and kiss his lips/teeth. "Whelp! I'm hungry!" I say opening the door. "Shall I make tacos?" Sans asked. "Sure, they'll good." I say happily.

Bonus:
Papyrus' Pov
I was walking upstairs because I heard moaning coming from Sans' room. Which was really weird. As I got closer I heard creaking. I crack the door open a tad bit and saw something I completely regretted seeing. I saw Sans on to of Y/n. Oh my fucking God!
