"Fixing" your sister's breast sizes

added by Nightmare49 4 years ago BM S

“Alright,” You speak up grabbing her attention right as she was about to leave your room. She stopped and looked at you. “Let’s fix your breasts.”

“Thank you.” Your twin sister thanked you. “Now can you just shot me before I just take that gun from you.”

“Jesh…. I am doing it right now.” You told her right as you take aim and shoot.

Your sister looked down to see her other breast start to grow. Her right tit pulsed as it slowly grew. She looked down and blushed as she felt the flesh filling up in her breast, with her right hand she cupped the boob as she felt it’s tiny “flat” breast fill out into a small size. The size of a large beach ball. “Thanks bro.” She smiled. “Now…. I really can’t believe that it works.”

You nod, “Same. But I guess I can now have the breast kind of fun.”

Your joke made your sister groan and roll her eyes. “Well then. What are we going to do?”

“We?”

“I want in on the fun.” She touched her pony tail boob. “I always wanted to trip my pony tail breast.”

You blushed at the thought. “Alright but we need to take turns or agree on things.”

“Deal.” Your sister holds out her hand to shake yours.
