After putting Phil down in her bed, Mary decided she would try to capture her neighbors. After the neighbors, the whole neighborhood. And after that... she smiled wickedly.
This was going to be difficult, however. Mary was a very large inflatable hippo, and it was going to be pretty hard to get people to climb inside her. So she would have to turn to the element of surprise. She squezzed herself out her front door and walked, bulk swinging back and forth, toward her crabby neighbor, Mrs. Silverman,'s house. She got to the front door and lifted a fat hoof and rang the doorbell. Then she dragged herself over to the side of the house. Mrs. Silverman opened her door. "Who the hell is there?" She yelled. Mary jumped and sailed over the house, spreading her legs. "WHAT THE..." was all Mrs. Silverman had time to say until she was firmly wedged inside Mary's vagina.
Mrs. Silverman screamed, but Mary just said, "Don't worry, Mrs. Silverman, you'll soon be happy." Putting pressure on her labia, Mary sucked Mrs. Silverman inside her fat belly. She beat on Mary's squeaky stomach walls, but to no avail. Then the grey goop shot out and covered Mrs. Silverman. She shrank and fattened, face puahing out into a shovel-like muzzle, tail plunking out of her fat bottom. Soon she was a baby hippo like Phil. Mary squeezed on her labia and shot out Mrs. Silverman. She flew out of Mary's vagina and hit a tree with a Loud thwapping noise. She was knocked unconious.
Mary picked up the now inflatable baby-hippo Mrs. Silverman and carried her into the house. She laid her down right next to Phil and contemplated who to change next...
