I indulge in solo pleasure while my parents are away, but they discover my secret and confront me

I'm a sweet 18-year-old who loves to indulge in some naughty fun when my parents are away. On this particular day, I decided to take things up a notch and get myself off while my mom and dad were out of town. Little did I know, they had a surprise for me. As I was pleasuring myself, my dad's best friend, my uncle, walked in and caught me in the act. He was visibly shaken by my actions, but I knew he wouldn't say anything to my parents. However, what happened next was beyond my wildest expectations. Both my mom and dad walked in, catching me in the midst of my solo pleasure. They were furious, but I knew they wouldn't be mad for long. After a heated confrontation, they decided to join in on the fun. What started as a taboo encounter turned into a wild ride of passion and pleasure. My parents, along with my uncle, joined in to teach me a lesson, but it turned into a steamy threesome that left us all breathless.
