Ah yes,
Certainly my fav situation: Dude is an unwitting survivor immune to the china virus, having set sail some months ago, and now finds himself alone at the next port. The COVID-19 pandemic - a chinese manufactured bio-weapon - has finally succeeded in killing more than 5.5 billion people across the entire planet. Walking around an empty town, he is clubbed over the head and taken to an Island just off the coast of wherever he docked. There he meets a 40-something women, who appointed herself as the Madam on the island (housing over 1000 females of all races, creeds, orientations etc.), sending this last surviving male on the planet on an unrelenting fuck-fest, with only a handful of rules:
1. No cumming outside of a woman. Ever. Each sperm must be used to try make a baby - creating new humans!
2. No jacking off and cumming outside a woman, if you are jacking off (or being jacked) you have to still CUM INSIDE A WOMAN, same for any and all non-intercourse fun. Always stock in back in the nearest non-preggo and cum inside her.
3. Fridays are 50-girl fuck days. Prepare yourself, always
4. No falling in love
5. See rules 1 and 2 again!
Set this game/story up on an Island (or deserted city/farm) with impregnation, raising children and eventually poking the offspring too, once they reach breeding age. Geez, this would be a festival of creampies and preggo sex, when not impregnating more women.
Devious, sexy and hot AF. Who wants to do the graphics for THIS story with me?
