I sit in our apartment, excitement causing my heart to quicken its pace. A threshold is on the verge of being crossed, one that beckons me forward. Well, not me precisely, but my wife, who sits across from me, her cheeks flushing with anticipation as her thoughts wander. Our mutual acquaintance is in the bathroom, unaware of the subtle tension between us.

My wife fidgets, her nerves taut, her gaze meeting mine as she bites her lip. Clad in a black shirt with a scanty built-in bra that offers minimal support, she presents a tantalizing view of her ample cleavage. Her shorts are unusually brief and snug, accentuating her thighs as they peek out from the hem. The sound of the faucet turning on in the bathroom signals his imminent return. Sensing the moment, she rises from her seat and heads to the kitchen for a drink. As she does, my eyes linger on the sight of her, admiring the curve of her behind and the swell of her breasts rising and falling with each breath.

"Would you like a drink?" she calls out to him as he emerges from the bathroom.

"Certainly," a simple reply with a smile.

She smiles and fetches three glasses, "Have a seat, I'll bring them over."

With precision, she fills the glasses with ice and opens the liqueur we had purchased earlier, hoping it would calm her nerves. Walking over, she sets down mine and hers first, then deliberately leans in low to place his, ensuring he has a prime view down her shirt as she does. A smile tugs at my lips as his gaze lingers on her breasts momentarily before shifting away.

The conversation flows lightly as we sip our drinks, the bottle gradually emptying as my wife ensures our glasses remain full. Taking a clumsy sip, some of the liquid escapes her lips and trickles down her chest, a deliberate display for his benefit. This time, his gaze is intent as she uses a napkin to dab herself, her hand slipping into her shirt, lifting her breast slightly as she pursues the elusive droplet. Catching him looking, she feigns an apology, "Oh! I'm terribly sorry." She quickly turns away, however her slight smile tells all.

"No, you're fine," he reassures.

A mischievous glint sparkles in her eyes as she briefly smiles at me before turning back, "Well, it seems like you quite enjoyed the view." His face flushes with embarrassment. Cupping her breasts and pressing them together, she teases, "I don't mind." His mouth falls agape as he looks to me for confirmation.

I nod silently, "Just between us."

Drawing her chair closer to him, she inquires with a sultry tone, "Would you care to see more?"

A mere nod is his response. She chuckles and tugs her shirt down, revealing more of her breasts but stopping short of exposing her nipples. She continues to tantalize him, his gaze fixated on her every move. While he refrains from reaching out, her hands explore him, gliding across his chest, caressing his leg, tracing his jawline, teasing but never venturing near his groin. His breath quickens, his eyes darting to me, awaiting a response.

Yet, I simply recline in my chair, relishing the spectacle before me. Leaning in, she whispers audibly, "You're allowed to touch, you know," as she guides his hand to her breast. A gentle squeeze elicits a hitch in her breath, her eyes ablaze with desire. "I have the freedom to do as I please," she declares, glancing at me before sliding her wedding ring across the table to me. "For tonight, I'm unattached."

His demeanor shifts as he firmly grasps her breast, causing her head to tilt back with a loud moan escaping her throat. Lowering her gaze to meet his, she extends her arm, gripping his groin, a gasp escaping his lips as he reciprocates. Dropping to her knees before him, she swiftly removes his shorts, freeing his member, which she immediately takes in her hands. Slowly stroking him, his eyes shut as he begins to groan with pleasure. She glances at me, a silent request in her eyes, and with a nod, I grant her permission.

Parting her lips, she delicately licks the tip of his erection, eliciting louder groans. Within moments, she has taken him fully into her mouth, bobbing up and down with fervor, moaning unabashedly. I can feel my own arousal mounting against the fabric of my pants. Her hand ventures up his shorts, presumably caressing his testicles, as his moans grow more fervent.

With her free hand, she frees her breasts from her shirt, catching him off guard when he feels the slap of her flesh against his thigh. His eyes widen, one hand moving to her exposed skin, the other to the nape of her neck, guiding her down onto his shaft. Tears well in her eyes as she gags on him, but she persists. This rhythm continues for some time until she pulls back, wiping her face, "Do you desire me?"

The question spins my head, my wife is inviting another man to make love to her, and I find myself enthralled by the notion. Without hesitation, he lifts her onto the table, deftly removing her shorts and panties in one fluid motion.

Diving into her moist folds, his ministrations elicit audible sounds of pleasure. Gripping her thighs, his tongue traces from her clitoris to her entrance, driving her to the brink. She clutches the edge of the table, moaning fervently, her gaze shifting between me and him, her eyes squeezed shut in ecstasy.

Locking eyes with me, I see pure desire in her, then she looks at him, "Give me your cock, ravish me!" He obliges without delay, lifting her up to the table top and thrusting into her. She receives him with a scream of delight. I remain seated, an observer in this chair, watching as my friend makes love to my wife before me. Their union seems to stretch on for hours, transitioning between positions intermittently. I even join in at one point, her mouth enveloping my member as he continues to claim her.

As the night draws to a close, my wife succumbs to exhaustion, drifting into a peaceful slumber. We engage in quiet conversation for a few hours, taking turns caressing her form as she rests, "Is this a singular occurrence?" he inquires, his hand resting on her breast.

"That, my friend, is entirely up to her now," I jest as I grasp her other breast, a soft moan escaping her lips, glistening with remnants of their shared passion.
