First time showering with my young step sister

I was in for a surprise when I walked into the bathroom to find my 18-year-old step sister taking a bath. I've always been drawn to her natural beauty and her perfectly shaped, big tits. As I started showering with her, the tension between us was palpable. I couldn't resist the urge to touch her, and she didn't object. I reached out and fondled her breast, eliciting a gasp of pleasure from her. She then began to stroke my hard cock, and it became clear that she was more than just a pretty face. She eagerly took my monster cock in her mouth, showing off her skills as a cock-hungry amateur. The sight of her beautiful face being fucked by my big dick was too much to resist, and I couldn't hold back any longer. I came hard, covering her young face with my hot load. It was a wild and unforgettable experience, and I know for sure that there's more to come.
