"Ohh.. Kat. How are you so good at this...?" You said with pleasure, as Katsuki massaged his fingers into the muscles of your shoulders. You sat still in the kitchen chair as he worked his fingers. "Before I had you, I would have to massage myself. Then I became good at it, because I know all the right spots." He said playfully with a cocky smirk. He slowly molded your upper back, causing you to melt. You were overjoyed you were able to get Katsuki to do this.
