Another in the genre of "be careful what you wish for" stories. The guys try to rig their weekly poker game to get the wives involved. It's all just for a little grab-ass; nothing hot or heavy. But things get out of control, and when the wives find out what's really going on, well, Hell hath ho fury like a woman scammed.
The story describes the accounts of Tom after his discovery of a drug that emulates the response of the female brain to ovulation and enhances it 1000x.
It makes women horny beyond control, releases eggs, makes them pregnant even if on hormonal birth control, numbs the gag reflex and pain of deflowering, among other things.
Tom discovers slowly how to use this drug to make a living, entertain a growing harem, cuckold, and ultimately spread his genes around the world.
