Uninhibited and authentic encounter with my stepbrother - cowgirl style and internal ejaculation

I've been craving a genuine and unreserved sexual encounter with my stepbrother for quite some time. His unquenchable lust and unfiltered passion make every moment spent with him an unforgettable experience. As I assumed the cowgirl position, I could feel his anticipation building up. His hands roamed freely, exploring every inch of my voluptuous curves, while his thick shaft found its way deep inside me. The sensation of his every thrust sent waves of pleasure coursing through me, my body writhing in ecstasy as I rode him relentlessly. The sight of my tight, pretty pussy being stretched to its limits was too much to resist, and I allowed him to climax within me. The sight of his release was a testament to the raw, primal connection we shared, a moment of pure, unadulterated pleasure that left us both breathless and satisfied.
