This one is based on the films of a similar name, which I loved growing up. Obviously it's for all you MACRO/micro fans out there...
There are six people in the Henderson household:
Doug Henderson, inventor and Radio-Shack store manager. Doug is a nice guy, and totally brilliant. He is building a I.S.R. (Incredible Shrinking Ray!) in the basement. He's a good guy at heart, but what will he do with this helpless, nubile thing?
Susie Henderson, the supportive wife. Susie is overall a nice woman, but she is jealous of Cas' good looks. When Cas is only five inches tall, what will Susie do with her?
Aaron Henderson, 16, the crushing teenager. Aaron has it bad for Cas. Who wouldn't? He has a hot, older girl living across the hall from him. Too bad she is oblivious to his heart-ache. Now that Cas is pocket-sized, all his fantasies can finally come true!
Jessica "Jez" Henderson, 17, the angry one. There is one in every house. She's the dark one. The one who is misunderstood. She's also the reason Doug and Susie need a stranger from another country to babysit their youngest when they go out for the night. What will Jez do when she gets her hands on a miniaturized Cas? What cruelties can she inflict on poor Cas?
Betsy Henderson, 8, the innocent one. Obviously, she won't come into the story much, except maybe to play barbies with Cas and dress her up like a princess.
"Cas" Petrova, 19, the exotic exchange student and sometime-babysitter. While babysitting Betsy one Friday night, Cas runs afoul of Doug's ISR! and is shrunk down to a mere five inches! Once she is miniaturized, she finds that her metabolism has skyrocketed, and how will she ever stay warm? Once she discovers how high in calories the love-juices of her adoptive family is, she finally can stave off the constant hunger!
This one is a more light-hearted, whimsical tale. Something goes wrong, Cas gets shrunk. Hijinks ensue. Since she is from another country, there is no real danger of her folks find out. What do the various members of the house do with this attractive-yet-tiny woman?
I will take the role of Cas. You will take the role of the various members of the household. Plotlines and kinks are all negotiable. PM me if you're interested in pursuing this.
