Secretly seducing and pleasuring my stepsister in the backyard

In the secluded backyard, I harbored a secret desire for my stepsister's voluptuous curves. Her mature body was a tantalizing sight, especially when she sunned herself on the balcony. On a lazy afternoon, I decided to act on my desires. As she lounged on the chaise, I joined her, casually massaging her back. The sight of her big breasts and luscious ass ignited a fire within me. Overwhelmed by desire, I unzipped my pants, revealing my throbbing cock. She caught a glimpse, her eyes widening in surprise but also arousal. With a mischievous smile, I urged her to take it all in. She eagerly obeyed, skillfully pleasuring me with her hands and mouth. The sight of her sucking my cock was a dream come true. As she worked her magic, I couldn't hold back any longer and came all over her face. The thrill of our forbidden encounter left us both breathless.
