Ace is your older brother. Him and you aren’t on the best of terms. You two have both been competing since the day you were born.

One day, he challenged you to a game of tag. (It took a long time so I won’t explain too much) You ended up winning.

You two were in a room together, he then started blushing intensely, this is why you hated him. He was a masochist, and he also had a humiliation kink… and time you beat him, he couldn’t help but feel extremely flustered at you beating him…
