Summary
“I know who you are.”
Shigaraki lifts your console up, turning it this way and that, ignoring your declaration. “The facing got knocked off,” he states, his four fingered grasp lifting it up for you to see. His eyes catch yours, the crimson ensnaring you. “I don’t think it’s going to fit back on. Lucky you, you don’t really need it to operate the machine.”
His pinky comes down against the plastic, joining the rest of his finger pads. The plating is gone in an instant, dissolving into a fine dust and drifting to the mats beneath Shigaraki’s feet.
Moving to Japan has been an absolutely terrible life choice.

Summary
It seems unreal when your Commander and your Captain suggest their bed might have room for another, but when the acts that were meant to be purely physical start to heal old wounds, the three of you wonder how any of you were surviving this whole time without the other two at your side.

Summary
I just adore sub Sans and gentle femdom. And sexual dysfunction is an interesting topic to explore. The sex scene is toward the end, in case you want to get right to it. I just couldn't help but sneak a little story in there. Caution: this includes political discourse that's meant to be funny, because let's face it, what's more hilarious than American politics, am I right?
