This was a request :D Also sorry I'm not used to writing about relationships with three people.

Note: The reader is very ticklish in this one-shot. Also, Diavolo and Lucifer are not romantically interested in each other.

Requested by lovely @Honeybaby263 :D

Your laughing wouldn't stop.

"Haha, pl-please stop! I-I'll tell you-- ahaha!" You begged between your laughing outbursts. If they keep this up for too long you'll get side cramps, which will be with you for the whole day.

I knew I shouldn't have teased them! You can feel a tear about to drip out, either from the laughter or your internal pain.

Diavolo gave a nod to Lucifer, who released your arms, allowing you to catch your breath. This was how they manage to get honest answers from you: Diavolo and Lucifer both jump you, Lucifer grabs you and pins you down by your arms, then Diavolo tickles you until they get an answer.

Sometimes, you wish you weren't so ticklish. It's such a shame.

"Well, where did Mammon go? This illegal casino is a problem, and him being a regular is also a problem," Diavolo stated, crossing his arms as his face became more serious.

"I don't know-- ahh okay I'll tell you! No tickles!" You shouted as Lucifer shot you an unamused glare, which he always does before holding you down in the "tickle (Y/n) operations." "Mammon went to hide at a restaurant! I think it was, um, Hell's Kitchen...?" Your voice wavered at the last word. "I'm not sure though..."

Diavolo grinned and ruffled your hair. "Thanks, (Y/n). I knew I can count on you!"

Lucifer gave you a nod, a slight smile on his face. "Alright."

You just nodded in reply, keeping your face down. Once they left, you allowed yourself to lift your head. Blush was apparent on your face.

Crap.

Days later, you walk past some demons in the hallway. You always had, and it didn't bother you as much as your first day at R.A.D, but it was their words that made you freeze.

"I heard that the human fell in love with both Lord Diavolo and Lucifer."

"I hope the feelings stop soon. It won't be good for the human, nor Lord Diavolo and Lucifer."

You turned around and walked away.

Shit.

It'll only be a matter of time before these rumors reach Diavolo's and Lucifer's ears. And once they find you...

You sped up, almost running through the hallways to your next class. Luckily, you didn't encounter either of the demons you didn't want to see at the moment and made it to your seat safely.

"(Y/n)!" A voice said, making you jump. You turned around, breathing out a sigh of relief when realizing that it was just Mammon, probably wanting to copy your homework.

The second-born marched over to your desk. "Lemme copy your homework! The one from yesterday!"

Called it.

"No, Mammon. We've been over this yesterday," you said firmly. Mammon grumbled to himself in defeat as he slumped in his own desk, which was placed on the opposite side of the classroom.

The school day quickly passed, and it became evening. You always jumped or flinched at the slightest of things, but neither Diavolo and Lucifer asked you about the rumor. Maybe it died down and never reached them.

Smiling victoriously to yourself, you flopped onto your bed and began browsing through some ebooks on your D.D.D. They probably never heard about it. I'm safe!

Lucifer and Diavolo slammed open your bedroom door. The avatar of pride grabbed you and pinned you to the bed while the demon lord's son began to tickle you mercilessly.

Ah, I jinxed it.

"Hahaha, what is-is it now-- haha!" You ask between giggles, writhing around on the bed in an attempt to escape. Lucifer quickly tied your wrists to your bed's headboard, then nodded in satisfaction as you twisted around to no avail.

(No I swear this is not NSFW--)

Lucifer smiled, a glint in his eyes. "We heard a rumor today."

"Is it true you have a, ah, what do they call them? A crush on us?" Diavolo chuckled to himself.

"No!" you shout. "Nope! Not true! I dunno where you heard it it's not true!"

"You answered rather fast," Lucifer murmured, smiling. "Are you sure it's the truth?"

"Yep! Definitely!"

"Let's tickle (Y/n) some more," Diavolo suggested.

And that was how they started tickling you. It was enough that Diavolo did it, but now that Lucifer joined in it became double the damage.

"How about now? Is the rumor true?" Diavolo asked, continuously tickling you.

"Haha, nope!" Can't let them find out can't let them find out--

They proceeded to tickle you some more.

"Now? Is it true?"

"N-no!"

Lucifer tickled your weak spot: your stomach. "Is the rumor true?"

"Nope!"

The tickles became too much for you to handle. Side cramps were starting to creep in from your continuous laughter.

"Now?"

"Okay-- haha, fine! It's true! Now-now stop tickle-tickling me-- haha!" you pleaded. Grinning in satisfaction, the two demons obliged.

"Holy crap... why did you want to know so much?" you grumble, laying as still as you can on the bed since movement makes your side cramps hurt more. "You could've just left it alone. Or maybe I was telling the truth from the beginning, and you tickled me and caused me ultimate pain for nothing."

"But in the end, the rumor turned out to be true, so there is no need to concern yourself with that," Lucifer said coolly.

Wow, Lucifer is smartmouthing me now.

"Well, to make this brief and short, I like you too," Diavolo said, smiling.

"As do I," Lucifer said.

You blink. "Wait so Lucifer likes Diavolo or--?"

"No, we both like you. We have no romantic interest in each other," Diavolo clarified before you could say that Lucifer was gay. "Only you." A cheerful smile on his face.

"Ah..." You were happy that they both return your feelings, but...

"So what do we do now?" you ask.

"Give us both a kiss or a hug or something," Diavolo proposed.

You got up, wrapping your arms around them both at the same time. Later that night, they both decided they want to sleep with you. So you slept in the middle between them on your bed, with Lucifer on your left and Diavolo on your right.

Asmo snuck in and took a picture with his D.D.D. before backing out. Let's say Lucifer was not happy when he woke up to everyone spamming the chat in the morning, due to the photo Asmo sent.

Yeah okay, I'm crappy at these types of stories I'm sorry ;-;
