Cherry Fae - Sisters Payback Promise Custom

***CUSTOM VIDEO*** I've just come home from class and I've really gotta pee! But you, big brother, won't let me go until you collect on that favor I asked you for. Taking me back to your bedroom, you taunt me and make me squirm around and do a little "pee-pee dance" until I feel like my bladder will explode! Finally you relent and let me go, except you make me pee in my panties for you. Unbelievable, since we haven't seen each other nude since we were little! It's weird though, because I'm turned on now just can't help but want to suck on your cock. Which in turn makes me hornier than ever, wanting you to finally fuck your little sis! Guess we're finally even!
