We are not alone for long. Just as we start to wonder if this is going to work as intended a strange man appears. She starts at the sight of him, but modesty gives way to exhibitionism. They make eye contact. He looks at me, getting a sense of the situation, and approaches. We say nothing, but I give him the slightest nod, and he takes the hint. My partner's hands are wandering all over her body, massaging herself as demurely as she can while trying to contain the ravenous inner slut that will soon make its first public debut. I sense her nerves and, reaching down to her pussy, I lightly tease her mound, then gently spread her labia open in offering. Now there is no mistaking our intention, and our visitor's curiosity gives way to obvious hunger. In an instant his polo shirt goes over his head, and his belt and shorts land in a heap around his ankles. I cannot see my partner's eyes but her approval is reflected in the lust our visitor shows.
My hands take a break from their massage to caress my partner's face. Her head is to the left of mine and I take a moment to caress her face and stroke her long hair, moving it over her left shoulder. I nibble on her ear. I bite her earlobe gently. My hands find her thighs and firmly pull them as far open as our position will allow, and I continue to play with her labia. While I have been doing all this, taking in her heat, her transformation, her abandon, her gaze has been fixed on our visitor, who has been artfully playing with the bulge in his briefs and her breathing is getting heavy.
Our visitor approaches, shedding his briefs. We're all naked now, and there is no lingering question or pretense where this is headed. He comes over to our left side where she turns her head, her eyes still fixed on his cut erection which is pretty close to eye level for her. My right hand is still playing with her pussy while my left hand grasps and pulls her left nipple. Her hands have been gripping my knees, I suspect because she still feels a twinge of modesty.
Then in a moment of spontaneity, with my left hand I reach out to grab our visitor's penis and gently guide it toward my partner's lips. Does he wonder if I'm bi? Does he get a cuckold vibe from us? I doubt it, I'm a man in my 50s who wants to give this woman, my partner, the freedom to have a new and delicious experience, and my guiding his cock to her mouth, which she accepts, is my way of showing my consent and encouragement that she make the most of him...of us...of the moment.
And my gesture has that effect. It's the last direction she needs from me. Her arms embrace his thighs as she plunges her mouth onto his cock. He needs no help with his erection but she loves the act, the submission that it implies, and in her enthusiasm she gives him a sloppy soaked cock, which she now fully intends to take inside her pussy.
