Unexpectedly, I discovered that my step sister's birthday had snuck up on me. I hurried to the store to purchase a gift for her, but all they had were seductive lingerie and a pair of enormous breasts. As a teacher, I had always been captivated by her alluring physique and enticing assets. Upon my return home, I presented her with her gifts, which she eagerly tried on. Her delight was evident as she paraded around in her new attire. However, unbeknownst to her, I had a special surprise in store - my massive cock. I unzipped my pants, revealing my impressive member to her. Her eyes widened in surprise and excitement as she took in its size. The sight of her beautiful face and those enormous breasts was too much for me to resist. Our bodies intertwined in a passionate embrace, our desires consuming us. This was my birthday gift to her, a moment of intense pleasure that she would never forget.
