He watched as his friend's hand found her waist, a gentle but firm touch that drew her closer. There was a possessiveness in the gesture, a subtle shift in the dynamic that sent a thrill through him. It wasn't aggression, but a confident assertion of desire.

He saw his wife lean into the touch, her body yielding with a grace that was both alluring and empowering. There was a silent understanding passing between them, a mutual acknowledgment of the unspoken. He felt a knot tighten in his stomach, not of jealousy, but of anticipation.

His friend's other hand reached up to cup her cheek, his thumb tracing the line of her jaw. It was a tender gesture, yet it held a hint of command, a silent claim. He saw his wife's eyes flutter closed, her head tilting back in acquiescence.

The sight of them together, so close, so connected, sent a wave of heat through him. He felt a primal surge, a deep-seated response to the display of dominance and submission. It was exhilarating, this surrender to the moment, to the unspoken desires that flowed between them.

He watched as his friend led his wife on his cock, their bodies brushing against each other with an intimacy that made his breath catch. There was a sense of inevitability about it, a natural progression that he couldn't deny. He felt a strange mix of emotions – excitement, curiosity, and a deep, abiding love for the woman who was riding another man.
