Julian watched the transformation, his own pleasure growing with each soft moan that escaped her lips.
Julia, her own breaths coming in quick pants, leaned closer, her hand moving from Isabel's shoulder to her chest. She cupped Isabel's breast, her thumb brushing over the nipple, before bringing Julian's face down to suckle it.
The sensation of his warm mouth on her was a new kind of heaven, and Isabel couldn't help but arch her back, pushing herself into his embrace.
Julian's eyes closed as he took her nipple into his mouth, his tongue flicking against it as he felt her body respond.
Julia watched the intimate scene unfold, her own arousal growing with each moan that escaped Isabel's lips. She couldn't resist the urge to join in, her hand moving down to Julian's cock as he continued to thrust into her friend.
She stroked him gently, feeling him pulse and throb with each movement. Julian's eyes snapped open, his gaze locking onto hers as she touched him.
Julia leaned in, her breath hot against Julian's ear. "Fuck her harder," she whispered, her voice a mix of demand and encouragement.
Julian's eyes darkened, and he complied, his hips moving faster, his cock driving deeper into Isabel.
Julian's hand found Julia's breast, his thumb and forefinger toying with her erect nipple before he took it into his mouth. He sucked hard, his teeth grazing the sensitive peak, eliciting a gasp from her.
Julia's hand tightened on Isabel's hip, guiding her closer to the edge. Julian's other hand joined his mouth, squeezing and rolling the neglected nipple as he bit down harder on the first.
Her muscles tightened around him, and she felt the warm rush of her release as she came.
Julian's own climax was close, his hips moving faster as he felt Isabel's pussy contract around his cock.
With one final, powerful thrust, he cummed deep inside her, his body shaking with the force of his release.
Julia watched, her own orgasm building as she felt the tremors of pleasure ripple through Isabel's body.
Isabel's eyes remained locked on Julia's, her breaths coming in ragged gasps as she felt Julian's cock pulse within her. Julian moaned, his body trembling with the intensity of his climax.
He had never felt so connected to anyone, his orgasm amplified by the intimate gaze he shared with both women.
Julian pulled out slowly, his cock slick with Isabel's juices and his own cum. He leaned over, kissing her gently on the forehead, whispering sweet nothings in her ear as she lay there, her body still quivering from the aftershocks of pleasure.
Julia couldn't help but feel a twinge of jealousy, watching the tender moment between them. But she also felt a sense of pride and satisfaction knowing she had been part of it, had guided Isabel through the experience.
Julian turned to Julia, his eyes smoldering with desire, and gestured for her to come closer. He guided her head to his still semi-hard cock, now smeared with the evidence of their shared passion.
Julia didn't hesitate, taking him into her mouth, eager to clean him off and taste the mix of their arousal. Her eyes locked onto his as she licked and sucked, her tongue swirling around his shaft, savoring the salty tang of their combined flavors.
"We're just getting started," Julian murmured, his voice a seductive promise. "We've got all night."
