Your sister made a deal with you; if you do all the household chores and do her homework for a month you get to see her naked. You've been waited so long for this day and now it's finally here. Your sister loves getting you hard and horny wearing slutty clothes and she's often teasing you, and today is no different. Slowly she gets you more and more aroused as she's slowly taking off her clothes. First she bends over and shows you her big ass. Then she shows you her big tits, the ones that you're checking out as often as possible. She wants you to touch them and suck on her huge areolas and nipples. Your sister talks softly, almost whispers and tells you how horny and wet she gets with your mouth on her tits. She can't help but moan and you can hear her breathing is getting faster. After a while she tells you to get down on your knees, she wants to see if you're as good with your tongue in her hairy asshole as you were on her nipples. Your sister opens up her ass cheeks and winks with her asshole, telling you to sniff and lick her musky asshole. She's pushing her asshole wider and wider so you can fit your whole tongue inside. Suddenly your sister needs to pee. She tells you to lick her pussy instead as she's peeing. If you're doing a good job maybe you get to lick her pussy even when she isn't peeing... You've been waiting so long to lick your sisters hairy pussy so you do as she says. And she had quite a lot of pee for you... But you're a good boy and licks your sister clean from pee. She then wants you to go back to licking her asshole. You're doing a really good job with your tongue, and your sister's pussy starts to produce a lot of white pussy mucus... Do you wanna taste it? Your sister turns around and lets you lick her mucus away as she face fucks you. You got her hairy pussy shoved up your face, and both you and your sister are loving it! You keep licking her and she starts to play with her nipples as she's riding your tongue. It feel so good and so forbidden! Your sister can't hold her orgasm back so she comes in your mouth. She twitches and with your tongue you can feel her pussy pulsate. This was too good not to do again! Your sister suggests you stick with the deal; you do all the household chores and her homework and you get to play with her naked body, her hairy asshole and wet hairy pussy again. Of course you say yes again. It's a deal brother!
