So My little sister got hurt the other day playing Hockey and she needed to get a minor operation on her knee. Thankfully when I showed up to the Hospital before the surgery to console her, our folks weren't around. Why does this matter, it matters because me and my sis have a dirty little love secret going on. You see we've been touching each others private parts for quite awhile and just last week we had sex for the first time. Her pussy was so tight it felt like a vice grip on my penis and I exploded within one minute. Today was different though and I fucked her for a good three minutes this time before I shot my load inside her mouth for safe keeping.
