Katherine and her sister had been waiting for this day for far too long. It had all started when Kath and her sister had found themselves accidentally kissing at a party, somehow they had both ended up in a dark closet unaware of who the other was, but oh god it had been a hell of a kiss. And when they had found out who the other was, well they had been a little freaked out at first, but had soon found themselves kissing again, with more passion than there should ever be between siblings. It was during this time that Katherine's sister also discovered her secret, that her elder sister was a Futanari! As much as they had wanted to go further though they simply hadn't been able to. They knew that once they got started neither of them would be able to hold back and they couldn't risk getting caught. They hadn't been able to go further at home because of their parents, and they couldn't do anything at school because the noise would almost certainly draw attention to them.
But now their parents were both going out of town at the same time, for a whole week no less! Oh this was just far too perfect. In preparation Katherine had stocked up on condoms and had held herself back from any kind of masturbation for almost 2 weeks now. God she felt like she was ready to burst, but she only had to hold back for a few more minutes now. "Bye mom, bye dad!" She called out and grinned, waving to her parents as they both headed out with their bags. Katherine had to restrain herself when the front door shut, her parents could come back for something forgotten after all. It was only when she heard car doors shutting, engines starting and the cars driving away that Katherine finally clicked the lock on the front door, then turned around and practically pounced up the stairs, throwing open the door to her sisters bedroom and licking her lips. "They just left sis..."
