My Fun Family

Jake woke up as usual to the sound of his sister running through the house and his morning erection straining against his boxers. He looked over at the clock and was happy to see that he had gotten more sleep than he expected.
It was Saturday and Jake was happy to get some sleep. He usually was awaken early by his younger sister or mom. No dad to speak of, seeing as he left when Jake was young.

But just as he was about to cum someone beat of the door.
