This naughty loli was in a store when she was suddenly thirsty. Instead of buying a drink, she decided to just open one in there and drink it without paying. After finishing her drink she had a really naughty idea: she drank the juice without paying it, so she had to refill the bottle somehow. After looking around to see if anyone was coming, she lowered her panties, put the bottle against her pussy and started to “refill the bottle”. After relieving herself, she just closed the bottle and put it back to where it was before, giggling while doing so. The one who buys it is gonna have a salty surprise!
