I stumbled upon a steamy scene when I heard moans coming from the guest room. To my surprise, it was my dad and my new stepmom in the throes of passion. I hurried to hide, but they noticed me. Instead of being angry, my dad welcomed me to join in. He urged me to enjoy the show as his new babe sucked his big cock. I watched in awe as she deepthroated his throbbing member, her pretty face getting covered in spit and pre-cum. Then, she turned towards me, inviting me to take a turn. I hesitated at first, but soon gave in to the temptation. After a wild session of face fucking, we both got to cum on my stepmom's beautiful tits. It was quite an unforgettable experience, one that left me with a newfound appreciation for the sexual dynamism in our household.
