step-sisters pee in the sink on family vacation

Description: My step sister + i are on vacation with our family. we rented a huge place but it only has 1 bathroom! this came at the worse time because we both have to pee so bad! we can't pee outside because there's too many people out + our step brother is taking an extra long shower. so we decided that the only option is to pee in the kitchen sink! violet winter came up with a clever idea that we should play 'rock, paper, scissors' to see who should go first. the girl that loses has to pee through their panties topless! violet lost so i got to pee first! i pulled my lime green bikini bottoms to the side showing my hairy pussy to my step sister. i peed for so long in front of violet since i had such a full bladder. it made her want to pee even more so bad. now it's violets turn + as she was holding her pee she managed to take her bra off exposing her pierced nipples. she then peed through her grey panties in the sink! we felt so relieved to finally be able to pee! but as soon as we finished, we heard the shower turn off + our strep brother come out of the bathroom. oh no! we rushed to get dressed + cleaned up the pee just in time! we learned so much about each other from peeing! very sneaky + so much fun!
