Today is a very special day for the protagonist, a rejected loner who
finds a gemstone that lets him control women in town for the next 3 days. And there's a decennial (10 year) festival happening in town...

"Anything I want..." he mused, and vowed to spend his virginity on
the hot milfs of the local Wives Club, and much more.

This would be a festival to remember. This would be a c*ckapalooza...
