She is having sex with no one but her partner.
It drives me crazy when people do that, you call her a prostitute but I bet you would jump her in a minute, I know I would if the opportunity came up.
It's funny I came across this couple because I like survival and bushcraft on youtube.
She gives you exactly what you are paying for.
Maybe you should wipe the orange stain off of your lips and put the flask of clorox down for a bit.
