nerd!hyuck who wasn’t only your boyfriend, but also your tutor.
he knows that his poor bimbo of a girlfriend struggled when it came to finals. and as the good boyfriend that he is — he makes sure to help you with it. but just studying didn’t do you any good, always ending up with you pouting and begging to bounce on his cock instead.
so, he turns it into an incentive. he holds you down on his lap, a worksheet right in front of you, your hands held to your back to make sure you don’t run. “what’s the answer, princess?” and when you can’t, a rough smack lands on your cunt, hyuck clicking his tongue. he slaps your cunt once again upon not receiving an answer, middle finger collecting the arousal on your folds, and he teases your hole, not fully dipping his finger in.
“you’re not getting this finger in your cunt until you answer, princess.”
