Leave Mary-jo with a gift

Sasha looked over Mary-jo, never losing that smile. Mary-jo stood there just shocked. How had this stranger done any of the things she had seen? This had to be a trick of some sort. Maybe a prank show. Not daring to move, her gaze shifted back and forth from Sasha to the hole her cum cannon had made.

"You really did do a great job Mary-jo. So good in fact that I think you deserve a gift." Sasha bent down and came face to face with Mary-jo. Pouting her lips, she planted them on Mary-jo's. Placing her hands on the back of her head she began kissing her. It was a pleasant experience for a few moments. That was until Mary-jo felt Sasha begin to blow air into her. Panicking, she attempted to fight Sasha off, but the grip on her head was too strong. One long drawn out breath continue filling Mary-jo. She felt the air spreading around her body, and it felt strangely pleasurable. Stopping her struggles sheballowed Sasha to do with her what she wanted. That was when she noticed that she wasn't filling up like a balloon. Slowly Sasha was able to stand up taller more and more as Mary-jo's body expanded upwards and outwards. Inch by inch she grew taller and heavier as her body began to sprout up muscles she had no idea existed. Once Sasha was standing at her full height she let Mary-jo go.

Standing in her tattered clothes Mary-jo looked herself over. She was as tall as Sasha, but while Sasha had a belly and looked fat, she was all muscle. Her eyes went wide as she lifted her arm and flexed her bicep. It exploded with muscle that looked extremely dense. Turning to look back to Sasha she realized the woman was gone. Looking down at herself she saw a new set of underwear had formed to give her some modesty. Smiling, Mary-jo headed back through the junk yard, excited to try her new body.
