"The Fruit Is Swelling" is a weird Category III skin flick with a premise it not only does nothing with, but seems reluctant to acknowledge.
It's about a fairly charmless, annoying eight year old girl who makes a wish that she can grow up because she is tired of being fobbed off over things sexual. Eg., her beautiful older sister goes out with boys and won't let the irritating tyke tag along.
Anyway, she makes a wish to grow up (by a "sacred tree") and wakes up the next day to find her role played by an older actress.
This older actress is pretty, but doesn't have a whole lot of sex appeal, which is weird since this is basically a soft-core porn flick.
She isn't alone in this escapade: her best friend, Fatty Girl, also gets an older body, though she probably should have also wished for a skinnier one. This character serves no purpose to the plot; her presence does nothing but make you ask questions such as, "Is that her real name, or a nickname? If it's her real name, how did her parents know she was going to be fat when they named her as a baby? If it's not her real name, isn't it cruel of Peach (the sort-of main character) to keep calling her Fatty Girl?" I guess the most pressing question of all is: what is she doing in this movie, since the movie does nothing with her? The movie really doesn't have a plot. You would think that the story of an 8 year old suddenly becoming 18 would have some obvious comedic and fantastic potential, but the movie doesn't really go for it. Instead, most of the time is spent showing people around Peach, such as her sexy older sister and horny, bald-headed dad, having sex. The sex is typical soft-core fluff and mostly pretty boring.
The ending has a swimming pool sex scene stolen straight from "Showgirls". It's the only part of this presumed "sex comedy" that could potentially raise a laugh.
