A hostel is a place to rest and sleep. And who likes to sleep without throwing a stick? Some people can't even sleep. That's why girls are always welcome there. And if she squirts to the delight of the audience, you can treat her to a warm cocktail in her mouth, on the house!
The girl just splashes sexual energy - from such a well every traveler would like to drink. And to fuck her while doing kamasutra is a pleasure for a guy.
