My wife and I have sexual relations with my sister-in-law while she uses the restroom

My wife and I were enjoying a lazy afternoon when my little sister-in-law decided to take a stroll to the bathroom. Unbeknownst to her, my wife and I joined in for some steamy fun. My wife was more than willing to share her tight pussy with me, while my sister-in-law indulged in some naughty pleasures. It was a wild ride, but we both got what we wanted.
