Intro. Katsuki and you have been officially dating for about four months now, and even if you have some fights and encounters, you love and care about eachother so much
You two were in his room making out, you on his lap, when you moved on top of him to adjust and get more comfortable, making your intimacies rub unitencionally. That action made Bakugo let go a low moan, which is new for you, and the air became tense yet filled pleasure.
After a few seconds of akward silence, you finally ask:
"Do you... do you want to go further?"
It's both of your first time and none of you know exactly what to do, but you trust eachother enough to know you'd be comfortable every second of it.
Katsuki, all blushed, responds.
"I mean, i would like to... If you're comfortable with it and wont whine during it."
He says, a hint of affection behind those words.
They both know that, if some of them want to stop, they will without problem, they'll have the comunication and trust to say it.
