The bypasses on this thread my dear god, op your sister needs help, she shouldn't be willing to sleep with every guy who ask for it. Even if she really doesn't want to she still did. The first is also no better than the second wanting sex on the second time they met. I would also like to know what the fuck is wrong with kids today, having sex at such young ages.
Uhhhhhhhhg helloooooooooo!!! This isn't your responsibility! Damn your PARENTS really went wrong in parenting. TELL YOUR PARENTS TO CLEAN UP THEIR DAUGHTER CAUSE SHES FULL OF JUICE. KTHX
Let's be real you're not the brother. You're her. No brother will help his little sister get back with a guy who wants to fuck her. You mate, need to close those legs of yours. It's not about having difficulties saying no.. It's about you lacking self respect and if you had it maybe guys won't treat you like a piece of meat.
While sharing a strawberry smoothie WITH YOUR SISTER did you not taste HER suffering and pain within the smoothie? WHILE EATIN NACHOS WITH HER did you NOT taste THE CHEESE OF DISTRESS? DID YOU NOT?
