Your family came on holiday with mine and you've always fancied me so when it's convenient you sneak into my room and it just so happens I'm getting dressed in my bikini! I start flirting with you and before we know it I'm masturbating while your watching me. I need to stop though. I'm so desperate to pee but you don't want me to stop and ask me to hold while we carry on mutually masturbating! It ends with a massive pee fountain at the end
