"D-Do you have to.. to do this i-in the halls?"

"Don't act like you don't like it. You love the thought of someone seeing us- the thrill of being mere feet away from your friends, barely hidden, while your boyfriend touches you like this.."

"I.."

"Anyone could walk out and see, and you'd probably want them to watch as I fuck you too, you pervert."

Shouto blushed even brighter at that.

He did. Shouto did want that, and Katsuki knew it.

"K-Katsu-"

"You would. You'd love it- I know what gets you hot under the collar. Participating, and being the main focus of voyeurism is a particularly strong like of yours." Katsuki whispered, then smirked. "Kinky bastard."
