Caught off guard, I stumbled upon my stepsister, MyAnny, in her room, her perfect, juicy tits bouncing as she rode a vibrator. Her moans filled the air, her wet pussy glistening, unaware of my presence. She switched positions, her big, round ass facing me as she took the toy in doggystyle, her long hair swaying. When she finally noticed me, she blushed, but her eyes filled with a naughty glint, inviting me to join. I accepted, my hard cock throbbing as I watched her perfect tits bounce again, this time on top of me in cowgirl. Our secret sessions continued, from missionary to reverse cowgirl, her big booty slapping against me, her long hair tickling my chest, until one day, she asked me to cum on her ass.
