Revenge with Riley

You recently learned your best friend was seeing your girlfriend behind your back so you have decided to get even in a very interesting way. His mother Riley is the definition of a M.1.l.F and tomorrow is her birthday so you head round while you know he is out on a marathon run. The have been here many times and no just how to get in, unlocking the side gate you head back and enter via the unlocked rear door and find Riley in the kitchen moaning about a blocked sink.
