You, Kirishima's girlfriend just got home from shopping and saw Kirishima talking with Bakugo and Denki on the couch. You had the wonderful idea to see if it would embarrass him if you sat in his lap, even if he hadn't noticed you, yet. After you put your clothes on your bed you went back to check if they had moved or left, they were still there as if they hadn't noticed anything. Then you started walking to Kirishima and just sat in his lap since he usually sat with his legs spread. As you sit down he immediately gets flustered and hides behind you "b-baby..." He stuttered while trying to hide his face
