In a twisted turn of events, I found myself in a compromising situation with my girlfriend's mother. It all started when I went over to her place to surprise her, only to walk in on her pleasuring herself. Despite my initial shock, I couldn't resist the allure of her mature body and the sight of her big, throbbing clit. What started as a brief encounter quickly escalated into a full-blown affair. My girlfriend caught us in the act, adding another layer of excitement to the mix. The thought of getting caught by her strict grandmother only fueled our desire, pushing us to explore new heights of pleasure. The sight of her mother, now a seductive granny, only heightened our arousal. We indulged in a wild threesome, exploring every inch of each other's bodies, losing ourselves in the heat of the moment. The thought of my girlfriend's mom, now a hot granny, satisfying my every desire was too much to handle. It was a day filled with lust, passion, and unforgettable pleasure.
