Sit by the lake
From Create Your Own Story
You decide to go sit by the beach and just feel the cool breeze blow across your body. You hear some giggling behind you, when you turn around it is only a couple of campers with an empty potion bottle. You decide to leave them alone because if you were a target for a joke there isn't much you can do about it now. About 5 minutes pass and you realize that you're suddenly very horny. A small part of your mind curse the other campers for this but right now you need sex, and fast! You see a couple of places nearby. Which one will you go to?
The big house (maybe you can get Chiron or Dionysus to fuck you)
The pegasai stables (you always wondered what that would be like)
