My 18-year-old stepsister joins me for a steamy shower

After a long day of college, I couldn't wait to jump into the shower and wash off the stress. As I stripped down, I noticed my 18-year-old stepsister was joining me. Despite being a year younger, she had already blossomed into a stunning young woman. Seeing her in her bathing suit, I couldn't help but notice her perky breasts and shapely ass. As the water started to flow, I felt a sudden urge to touch her. She didn't object as my hands roamed over her body, eventually finding their way to her wet panties. The feeling of her naked body against mine was too much to resist, and before long, I was thrusting my hard cock into her. The sight of her young body writhing in pleasure only fueled my desire, leading to a passionate encounter that left us both satisfied.
