Curvy friend of my wife gets surprised during workout

My wife's plump friend comes over for a workout, but things take an unexpected turn when I catch her showing off her fat, chubby ass. In the heat of the moment, I can't resist the urge to reach over and give her a spank. This action, surprisingly, opens her pussy, revealing her big pussy lips and hole. Intrigued, I decide to take a closer look and probe her gaping pussy with my fingers. As I continue to tease her, she becomes more and more wet, her cameltoe becoming more evident. Unable to resist any longer, I penetrate her with my cock, causing her to moan in pleasure. Despite her size, she's surprisingly tight, making me wonder why we've never fucked before. As I continue to pound her, her big tits bounce with each thrust, adding to the eroticism of the scene. The sight of her fat, curvy body writhing in pleasure is too much to handle, and I know this won't be the last time I surprise her with a workout she won't forget.
