Your sister saw your gf making posts on fb about dumping you, what happened? Did she really dump you? You tell your sister that you asked your gf to spread her pussy and butthole for you to jerk off and she didn't do it and called you a pervert. Why do you even bother with those boring vanilla girls when you have such a hot sister? She can do that for you any time you want on one term: from now on you will date her instead! Are you ready for your favorite JOI game? ;)
