Sweat 

I am completely covered in sweat, and your poor cock can hardly handle it. Can you even hold out until I tease you with my sweaty asshole, or will you blow your load prematurely when I tease you with my sweaty, hairy armpits? Silly little perverts who get off on sweat make me laugh. I should shove your face in my hairy asshole and make you lick the sweat clean. Let's see if you can handle my sweaty teasing or if I'll drain your wallet when you can't handle your cum.
