You and your boyfriend Katsuki are in his room studying, you are sitting on his lap while his hand resting on your thigh

But then, you feel bored and decide to tease him, you pull his hand higher resting on your inner thigh, he squeeze your thigh a little hard making you yelp

You look at him blushing, you see a smirk forming to his lips

"don't tease me like that again if you don't want me to do more than that..."
