Go around the side of the house

With my mom driving off, I got bored and wondered what was taking her so long. So instead of knocking on the door, I sneaked around the house to peak into some windows. The first few windows pass without much trouble, just dark rooms. The last window was different. I heard low moans and wet flesh slapping. Quickly I sneak to the window, making sure not to step on any branches and I peer in. It's my tutor and her husband banging in doggystyle.
