Not really

The night is pretty uneventful, the girls both cuddle up to John and their legs wrap around his. It was about 6AM when Susan woke up, both Sarah and John were still asleep. She got up and went to the toilet and then got a glass of water from the Kitchen. When she got back she stood for a bit sipping her water and looked at John and Sarah sleeping. By now they had separated themselves from each other with John lying on his side and Sarah on her back.

Susan continued to watch her step-children sleep, rubbing her pussy as she thought about the night before, she yearned for both Sarah's pussy and John's cock. She continued to rub her pussy, occasionally slipping a finger or two inside while thinking what she would do to her step-children if they woke up. She was still thinking about this when she decided to do something about it.
