This gives me such strong feelings, idk why. I see an older brother, carrying his sister away from someone bad, or someone who has betrayed him/them (maybe an aunt or other far relative who has been raising them). Such a story in one gif.
We were staying after school he got us detention we are working out problems on the board when the teacher left. While doing so he grabs my waist I push on him away. He pinned me to the wall kissing me. I was surprise but I suddenly kiss him back.
