God I wish I had a sister, I only had a brother and we had to settle for sucking each other off as we got older. Neither one of us wanted to give up or assholes at first. But eventually I let him gay fuck me and bust in me and he said I had the tightest hole out of any girl he’d ever fucked, even in the ass! So finally he let me have a go cause I fucked him 100s of times first and he liked it too! Now me and my brother share a room in our 1bed apartment and just fuck each other every day. It’s better this way because we don’t turn our backs on family.
