He knocks her out

The man takes Jade by her fire-red hair "I might just keep you here for a little bit" he says while grinning. "when I say a little bit...I mean 5 hours" Jade remembers that if a girl hasn't moved in 5 hours then every man on the island knows her location. "and so you wont get away..." he uses a pressure point to knock Jade into a deep sleep, she dreams of her first time and if she actually wants an orgy. She dreams of dozens of men fucking her soon not so tight pussy and knocking her up. Her pussy gets wet as she dreams and the man happily licks it up, which makes her even wetter.

Soon she's squirting for her captor, surely if she woke up now she wouldn't want to leave, instead be ready for round two. And most likely even more rounds.
