【Petite Otaku Doodle】Baruhara! Big sister’s pounding balloon torture

This is a CG collection of the story of my brother (and his friends) being blamed by my sister for the balloon and making them squirm.

“I tied my sleeping brother to the bed and put a balloon in his pajamas.

He wakes up, but the balloon is so full it’s about to burst, and when he tries to escape, he’s restrained and unable to move, and more air is pumped into the balloon.

-When you’re in class at school and you’re trying to write down your answers, but you’re worried about the balloon that’s expanding in your pants.
-As a punishment for not answering the question, they put an acrylic case with the name of the party on my face and put the balloons in it.
-A giant balloon hug and split at a field day. But it’s not easy to break them, and her vagina tickles in front of the students.
-balloons at a balloon club activity.
-Balloon blowing contest with the master (customer) in the balloon cafe where she works.
-Pseudo breast pumping with balloons in the chest
-Inflating balloons in master’s briefs with her mouth
-Thumping balloons while inflating balloons inside your swimsuit
-Sister and brother in full body tights with balloons blowing up their stomachs, crotches and asses.
-Pump shoes are used while wearing them. The more you walk, the more the balloons in your costume inflate.

The more you walk, the more the balloons in your costume will expand.
