Wife submits to humiliation and ass play with cuckold friend

After years of being a dutiful husband, my wife and I have found ourselves in a bit of a rut. Luckily, my friend has been eager to help spice things up. He's always been a bit of a pervert, but he's also a cuckold enthusiast. So, when he offered to join us for a night of wild fun, we couldn't resist. The night started off innocently enough, with my wife and I sharing a bottle of wine. But as the night wore on, things took a turn. My friend started to tease my wife, calling her all sorts of naughty names. It was a sight to behold as he stripped her down, revealing her luscious ass to him. He wasted no time in giving her the attention she craved. He spanked her, slapped her, and even used his fingers to explore her tight hole. It was a sight that left me both terrified and aroused. And as I watched, I realized that this was exactly what my wife and I needed.
