Shidou watches intently as Denji's shirt comes off. Okay, yeah, this kid is Chainsawman. He's rimming his favorite superhero. That's like, the biggest fucking ego boost ever. And Denji does have a nice body. He's not as developed as Shidou, but Shidou worked fucking hard for his body. If he had to guess, Denji only started working out when he became Chainsawman. But that's all conjecture, and it's not like he will ask Denji right this second.

Not when he's been given permission to finger him. "Fuck. You sure? Keep your legs spread for me. I'll get the lube."

He lets out a snort at the admission of hating this and playfully nips Denji's inner right thigh before crawling up to the bedside drawer where he put the lube. "You're just not used to letting yourself feel good." He coated his finger and snuggled up against Denji, kissing his neck as he circled Denji's hole and then slowly pushed the tip in. "I'll show you where the prostate is and give you one hell of an orgasm." He kissed down, getting on top of Denji. He stays clear of the starter cord and takes a nipple into his mouth with a pleased hum as he pushes his finger into the second knuckle.
