1: The party is on the beach, every Friday night after sundown (at or after 8PM). You don't need to wear a swimsuit to get in.
2: You meet a new face - Jill or Jack, depending on your in-game preference towards men or women. Jill/Jack like to play wingman - they will recognize others in the crowd, and nudge you to go and have sex with them.
3: You can choose between Claire, the sexy nurse (even as a female), Victoria/Gordon, the dom, and Norman and Destiny, the gym instructors. One night you can only choose one, but you can come back any Friday to have some fun with someone else.
4: If you´re the submissive of either Gordon or Victoria, they won´t acknowledge that - you can´t get a punishment here, this party is just about the sex and good vibes.
5: Currently you cannot have sex with Jill/Jack, unfortunately - but that might change in the future. :)
6: Happy Anniversary, Hornstown!
