"Well then, if you've nothing to give, maybe you'll take something instead."  The male said as he advanced, tugging his loin cloth off.  He began stroking his cock as he approached and the female behind him began rubbing her hands across her body.  "Mmmmm yes, take her baby.  Make her your little bitch.  I'll have her next while you watch."  The woman pulled her loin cloth off as well exposing a furry but engorged vulva.   It was obvious that they weren't going to let you go unmolested.  You could fight them or try to run.  Though a small part of your mind thought it might not be the worst thing in the world to join in either.
