And I mean, you know, twitter and tiktok and pinterest, they're... they're great. They're great. It's just... It's ao3. It's not the same without you.

this inspired me to leave the ball gag out of things in favor of free-range slurring and jaw-dropped moaning

atsumu getting fucked dumb and going incoherent, and the only words slipping out his tongue has are barely understandable because not only has his accent gone so strong, he’s hiccuping and sobbing so much.

atsumu has kiyoomi tied up, his mouth taped shut, and completely naked on the floor beneath him. all while atsumu’s works his foot, jerking kiyoomi’s cock the best that he can, and making sure he’s maintaining eye contact with kiyoomi.

#skts #sakuatsu | omgrvs , o!atsumu × a!kiyoomi omega atsumu who purrs very loudly, almost feeling like his whole body vibrates with it to get his content across. and alpha kiyoomi who loves it with his whole being, every time he hears or feels it he starts crooning too

nsfw// #skts #sakuatsu "Stop fucking squirming and take it," Kiyoomi growls as he uses his hold on Atsumu's arms as leverage to fuck into his deeper. Atsumu wails in response, body falling limp at the command save for subtle twitches as Kiyoomi brushes across his prostate. +
