After Scootaloo almost drowned, Rainbow vowed to teach her adopted little sister how to swim, so she, along with the local lifeguard Fluttershy, are getting the pool toys ready so Scootaloo can swim and have a good time with her big sister.

My headcanon is Rainbow Dash and Fluttershy blew up the water wings almost all the way to help Scootaloo finish the job.

Commissioner Note: Einsman for Luna's sake stop slapping "weird fetish" on pictures you don't like. I don't want to get a mod involved but I will if this continues. Since when did derpibooru become the kinkshaming community if you seriously think this is solely a kink pic. (It's not.)
