Ore no Buka ga Eroi Mousou wo Yamete kurenai
Work Senpai is a psychic who can read minds. He accidentally reads the mind of a cool and calm younger coworker, only to see himself inside the guy’s WILD sexual fantasies even at the company, during meetings, break time, etc. Seme is handsome and collected on the outside, but inside he lustssssss for the Uke, and the Uke couldn’t help but to fall for him too. They’re freaking hot together, and the fact that Uke can use his telekinesis to guide the Seme’s DICK to his good spot is the fucking chef’s kiss in all of this!
