{Diavolo smut - The devil's fantasy}

--

Authors note: People demanded a special smut chapter, and who am I to deny them? Fair warning, I've written 2 smuts fanfics in my existence. So this might be bad. Also Doppio is here, just takes a back seat for Diavolo, this ain't his smut lol.

Warning: Stalking, masturbation, fantasy/delusional sexual thought, scent kink/underwear sniffing

Doppio stood in his room in the villain's mansion, dazed and confused about his surroundings. He felt slightly dizzy but he quickly blinked away the fog from his eyes, looking around his room.

"Huh? What was I doing?" Doppio gasped looking around the room. "My room?" He mumbled before sitting down in his bed but quickly jumped back to his feet, feeling his hand touch something soft.

Doppio turned staring down at the underwear lying on his bed. Doppio let out a silent scream backing so far away he hit his bedroom wall.

"No way, it can't be." He whispered looking at the hand that touched the soft fabric. He slowly brought his hand closer to his face, smelling a familiar scent but stopped hearing a ringing.

"Tururururururur... Huh?" The 'phone' rang as Doppio started to look around. "Trururururururur! My phone, where is it!" Doppio started to dig through his pants pocket pulling out his wallet and pressing it to his ear.

"Click! Boss, is that you?" Doppio said holding his 'phone' close. "Yes, mio dolce Doppio[1]." Diavolo said lowly watching through one of Doppio's eyes. He spotted the underwear lying discarded on their bed.

"Did you not like my gift, my dear Doppio?" Diavolo asked, dissatisfied his friend didn't jump at the chance in front of him.

"Wha, the underwear? B-But I don't understand-" Doppio was interrupted. "I think you do understand, my sweet sweet Doppio. You know that smell anywhere, and so do I." Diavolo informed Doppio, as Doppio felt a tent start to form in his pants.

"Ah, no way. It can't be hers. She'd hate me if she knew." Doppio mumbled crossing his legs and trying to bring down his boner.

"What she doesn't know won't hurt her, you deserve a reward my Doppio. You can let it all out." Diavolo said trying to coax Doppio to use the underwear.

Doppio body almost moved on his own as he sat on the bed, the underwear sitting sweetly right in front of him. It was tempting him like the forbidden fruit in the bible. Doppio felt his cock twitch in his pants at the fabric a foot away from him.

"I-I can't, it wouldn't be right!" Doppio reasoned, using all his self-restraint from pouncing on the clothing and getting lost in it.

"Why not, my Doppio?" Diavolo prodded.

"... It's disrespectful," Doppio said plainly gripping the fabric of his pants like his life depended on it. Diavolo's annoyance at Doppio's innocent ways started to get to him. Doppio's relief was his relief so the longer he waited, the more Diavolo craved a piece of (Name).

"She will be ours in time. There is no need to be ashamed my dear Doppio." Diavolo tried convincing Doppio one last time.

"Ah then it doesn't matter, we can wait! Wait for her to come to us." Doppio reasoned squeezing his legs together, desperate even for even a little friction.

"You are mistaken, my Doppio. You can wait, I cannot." And with that sentiment, Diavolo took over the body. He blinked a few times feeling his clothing get even tighter around him as his body grew.

He groaned feeling his cock throb in his pants. Diavolo looked down seeing the outline of his dick in the purple jeans Doppio loved so much.

He wasted no time unbuckling his belt and zipping his fly down, revealing his dark burgundy boxers trapping his dick.
