This mod was designed for use with (but doesn't require) Free Love, which recognizes the increased bed size for multiple bed partners.
A config file is created when you run the game with this mod. Here are the config entries:
{
"EnableMod": true,
"BedWidth": 5, - how many tiles wide the bed should be
"SheetTransparency": 1.0 - how transparent the blankets should be (1.0 means opaque, 0.0 means completely transparent blankets)
}
