It was currently night time- you know, the time where people are asleep? Nevermind, you don’t know that. Hell, you’re outside in the forest of ReaperTale, wandering around in boredom. Yep, it’s fun being an insomniac, right? That’s not the point, though.

‘Ya see, you’re the goddess of Lustful Desires. Before you say “Ew!” or “What? No!”, listen to me.

You’re the goddess of lustful desires, yes, but that doesn’t mean you’re perverted. Sure, you’re a bit flirty every now and again, but you don’t mean it all the time. You mean it in a joking type of manner. Except for one person, though…

Yep. Good ol’ Reaper Sans. A good friend, really. Your personalities match each other’s, making it easier for you to hang out and not be uncomfortable whenever someone says something as simple as a flirt. Though, when you say one to him, you notice a tiny, black, blush with appear on his cheek bones. 

Now, obviously, you knew Reaps liked you more than a friend (like earlier, you’re the goddess of lustful desire). And he knew too, you had both confessed to each other! You guys were both in a healthy and loving relationship!

So now that you know more about your background, I should probably explain why you’re wandering around in the dark, alone in a forest. Well, as I said before, you basically don’t sleep. So, you decided ‘Why not go to Reaper?’ 

That’s why- oh look! You’re there! Well, since you have now been informed, I shall be taking my leave. I’m curious to see what’ll happen after all…~

As you arrived at Reaper’s house, something seemed odd. Suddenly, you remembered what the date was. 

Oh gods.

Reaper was in heat.

“Welp, no turnin’ back now…” You mutter quietly, walking into the house. Of course, Papyrus was gone due to work, so it was just you and Reaper inside the house. 

A small glow coming from Reaper’s room had caught your attention. “Reaper? Babe?” You called out in hopes of getting his attention as you walked up the stairs, your long, silky, black and bright violet dress trailing behind you. Hearing a small swear and a light ‘thump’, your curiosity grew.

You walked closer to the room before peaking your head in through the crack in the door. What you saw made you blush heavily. 

What you saw was Reaper, except he was on his bed, his body glowing black. His cloak was off (probably due to the heat) and was instead wearing a black tank top, a pair of black boxer briefs, and a sleeveless hoodie. But that’s not what made you blush, no no no.

What made you blush was the fact that he was moaning your name quietly, jerking off. He was panting quietly, his voice low and almost completely silent. But you being you, you found yourself looking at Reaper’s member. It was dark black and about average length, but was thick as hell. Just the sight of it made you wet.

Deciding to be sneaky, you slowly walked into Reaper’s room, slowly walking over to his bed. Luckily, his eye sockets were closed so you had no problem walking without gaining his attention. When you were close enough, you realized something; how the hell were you gonna get to where you wanted without making the bed squeak?

Deciding to say fuck it, you quickly and quietly got on without the bed squeaking. Thanking whatever gods helped you,you managed to get on the bed without Reaper knowing. Striping yourself quietly, you set your dress down. You never wore a bra or panties due to the annoyance and aching feeling you get wearing them, so you gave up completely.

Reaper opened his eye sockets, blushing when he saw you. He's seen you nude before (obviously, you guys aren't virgins anymore), but it was shocking that you actually came over; during his heat, nonetheless! 

“Y-Y/N…? Wh-Why’re you here…?!” Reaper asked shakily, looking at you with a black blush. 

You giggled softly in response. “I wanted to help you~!” You purred. 

“W-Wa-ait, why-!” You cut him off by straddling his waist, pinning him to the bed. You giggled once more. “Relax, Babe~!” This seemed to calm him slightly, his body un-tensing slightly. Grinning, you looked over the body you have grown to love so much.

Reaper squirmed slightly under your gaze, groaning softly when you began to grind yourself against him. You had discarded his boxer briefs, now grinding your wet folds against Reaper’s thick member. You moaned quietly before stopping and leaning your face to Reaper’s, capturing him in a loving and gentle kiss.

Groaning quietly, Reaper kissed back as he grinded slowly against you. You mewled quietly into the kiss, but grinded back in response to it. Reaper slowly entered himself into your entrance making you moan into the kiss. Pulling away from the kiss, you quickly got Reaper's cock inside of you. Moaning loudly, you began bouncing up and down. The room was instantly filled with moans and groans from both you and him. 

“F-Fuck, Y-Y/N~!” Reaper groaned, using his hands to guide you down on his dick. 

You moaned out louder as you felt Reaper fill you up. Gods it felt amazing. Just as much as last time. You didn’t even realize how much time went by before you felt him throb, your tight walls clenching even more as Reaper came with a lewd moan. 

You came right after, both of you now panting softly. When your guys’s breaths calmed down, you looked at each other longingly and lovingly. Reaper’s body slowly de-summoned, the cum disappearing as well. Reaper’s skull and your face quickly connected, both in a hungry but loving kiss. Pulling away, there was only silence before small laughter was made. You cuddled up to Reaper, said skeleton holding you close. No words were needed as you both slowly fell asleep, appreciating the warmth you both felt from each other.
