While the woman behind the horse person took a seat next to some of the other women who were also wearing black dresses, you see the weird looking horse stranger go over to a microphone that was on stage. You heard that hosts of the party had to do that to assure the guests of what was going to happen.
"Ladies, and gentleman," the horse creature says, while he was holding the microphone up to his face. "My name is, Eldrotine. Welcome to my party, where I'm sure you will have plenty of sexual fun. We have a pool, a snack buffet table, and plenty of company for you to get along with while you're here. My 10 wives are also available to have sex with, seeing how I'm not permanently married with all of them, so they're of course free to mate with while you are here. Have fun everyone.
