Sara screams in terror as she watches the bulbous, purple, marble like head of her father's giant penis move ever closer to her. More accurately, she is being pulled toward her father's penis by the strong current.
"BEN, HELP ME!" she screams.
"I can't Sara", Ben replies, sounding terrified. "I'm being pulled toward it too".

The giant cockhead quickly grows larger and larger, until it completely fills the shrunken children's field of vision. Sara slams into the tip of her dad's penis, just to the right of the vast, vertical slit of the urethra. Sara knows that, at her current size, the slit could easily swallow her up. She tries not to think about it, but it's too late.
Sara has quite a vivid image of the slit suddenly growing teeth and grabbing her by the feet. Once it has a firm grip, she is slowly eaten alive by her own father's gigantic penis.

"SARA!", Ben shouts as the last part of her body is pulled in.
He manages to swim over and peer in from one side.
"SARA", he shouts. "SARA!" But he gets no reply.
Ben's instinct is to try to get his sister back from her genital prison, but a voice in the back of his mind tells him to try to get to safety. He pauses for a moment while he considers things, and then he:
