This is just a rough idea, but i think i would be interested in playing a game like this. The town of Ravenbrook is a town on a small off shoot of land on the eastern coast of the US. It is surounded by wilderness, and a bit of a ways back, mountains, meaning that the only method of arrival and departer from the town is by ferry. It is an adult comunity, but many 18 year old college and university students tend to visit in the summer months to find work, meaning their is a good variety of the ages of people living in Ravenbrook.It is a nice comunity of 300+ people where everybody knows your name, unless you are a stranger.
However, one morning the towns people awake to find a strange greenish fog rolling through their town. While fog is not uncommon, it is certainly not common to see green fog, or thog that is this thick enough to obscur ones vision twenty feet away, quickly prompting the town mayor to ban the use of all cars. To make mattres worse, cell phones no longer seem to be able to call anbody and the town is not able to get any radio signals from outside of the town, with static on every radio.
However, this is just the beginning of the weird events. As the days went by, townsfolk noticed that the clothing they wore out into the fog seemed to be becoming more and more brittle, seeming to be easily torn, by a simple tug on it. After several das it became emberrassingly evident that if a person wore clothing out of the house for more then a few hours, they wouldn't likely be coming back with them. After a week, it quickly became common place to see naked people everywhere,as shyness was forgotten to be replaced by the need to go to the grocery store or to ones favourite diner.
The strangness didn't stop their though. As the days of the fog conitnued, with no contact to the outide world, people started to notice their bodie were changing. Fat was seeming to burn off peoples body's at a surprising rate. Men were finding that their testicals seemed to be swelling up, and always full of seed, while thier penises seemed to be growing longer and thicker. Women also seem to be feeling the eefects of the fog, as their breasts seemed to swell, increasing in size and perkiness, looking like implants but will all the feel of natural breasts. People of both sex's are also noticig a level of increased arousil in themselves and other towns folk. many have become more flirty with each other, and their seems to be sexual undertones everywhere. The fog seems to make maters worse, as simply being in the fog will make a man erect an keep him erect for hours even once he's back inside. Women seem to be suffering a siilar fate as well.
While it was wierd, everything seemed to be fine. Until the disaperences started.
Now, this is just the basic concept of the game. While one on one is fine, a few players would be great. I'd like to make it clear that i have no interest in being the DM, just a player. If somebody would like to be the G but wants some help coming up with ideas, i'm more then willing to help. At most i would recomend 4 players plus the GM, but it will be the GM's decision. While their will be plenty of opertunities for sex, a good part of the game's focus will be on the mystery surounding the fog and the disapearences of people.
