Jane continues riding Mark while asking John if he wants to join them

John's eyes remained glued to the scene playing out before him. Jane's body moved with a blend of determination and delight, each slide onto Mark's immense length a testament to her growing desire and newfound confidence.

Amidst their shared pleasure, the room was filled with a chorus of words and breathy moans, an erotic symphony that seemed to reverberate through every inch of the sauna. Mark's voice was a seductive whisper, his words igniting sparks of arousal in both Jane and John.

"God, Jane, you're so fucking tight around my huge cock. I can feel every inch of you."

Jane's response was a throaty moan, a mixture of pleasure and agreement. "Mmm, Mark, your cock is stretching me so much. I can barely handle how big it is."

As Jane continued to ride Mark's substantial length, her movements grew more urgent, her hips rocking with a rhythm that matched the rapid beat of their hearts. John watched, captivated by the display, his own arousal driving him to the edge of his restraint.

The intensity of their connection seemed to escalate, the words and passions fanning the flames of desire. Jane's lips met Mark's in a passionate kiss, her body undulating against his as their mouths melded in a fervent embrace. John couldn't deny the pang of jealousy that shot through him as he witnessed the intimate kiss, but his own arousal was too all-consuming to let it consume him.

Mark's hand slipped down to cup Jane's round buttock, a possessive gesture that seemed to only intensify the fiery passion between them. John watched as their tongues danced in a sensual tango, each movement a testament to the deep connection they were forging. He watched as Jane leaned backwards, her hands finding purchase on Mark's knees, her breasts exposed in all their glory.

As the scene continued, Jane's sultry gaze suddenly turned towards John, her eyes smouldering with desire. His breath hitched as he met her heated gaze, feeling a rush of arousal at the potent invitation in her eyes.

Jane's gaze traveled downwards, her eyes locking onto the rhythmic movements of John's hand stroking himself. With a teasing smile that sent shivers down his spine, she posed a question that hung in the air like an electrifying promise.

"John," she purred, her voice dripping with seduction, "would you like to join us?"
