Your sister informs you that she has been doing online shopping using your credit card. In fact she also bought the microbikini she is wearing right now! What the fuck? You are not allowing her to use your money and dress up like a slut! But it's not that bad, just take a closer look of her microbikini! Wow you can clearly see her pussy and nipples through the fabric! Ok, now you decide that's it time to teach her a lesson and lock her in the room. There is one problem though: she REALLY needs to pee! Will you let her out? Please? No? Fine, since that's the case, then she will pee and make a huge mess right in the middle of your room! OMG it feels soo good to let it all out! Wait a min! Did you do that just to see her pee and lick her pussy clean? ;)
