Description
It was my day off at work, my wife went to took the kids to their grandma and I stayed alone with my sister, that is temporarily (more than a year) staying at our place since she left her husband. Because she's staying with us, she's always saying she wants to help on everything she can, so I told her that every morning I get horny and my wife is not available, she could help me, like she did when we were teenagers and slept on the same bed in our parent's place. She's glad to help as you can see.
