Let me be clear—I adore my stepsister, but she's been driving me up the wall these past few weeks. It all kicked off innocently enough: we both love hitting the gym together, but our trainer? He's got this magnetic allure that leaves us both breathless, our pulses racing every time he demonstrates a set. I'm not usually the type to scrap over a guy, but this one felt like a prize too irresistible to ignore. And to make matters worse, she always seems to crave exactly what catches my eye, turning our sibling bond into a battlefield of unspoken rivalry.The tension boiled over so fast that we ended up in therapy, spilling our frustrations to a calm, professional listener. Our therapist, with his steady gaze and reassuring voice, insisted we had to master the art of harmony—learning to share space, energy, and yes, even desires. I couldn't envision it working until he dangled something truly tantalizing: the chance to indulge in him, together. It began with the gentlest of steps, easing us into vulnerability. He guided us to clasp hands, our fingers intertwining with a mix of hesitation and spark, followed by feather-light kisses on each other's cheeks—innocent pecks that carried an undercurrent of forbidden warmth.The air thickened as he coaxed us further, urging a single, lingering kiss on the lips. Her mouth was like velvet against mine, so plush and inviting that a wildfire ignited within me; I ached to plunge deeper, to let my tongue dance with hers and imagine how that exquisite softness would tease and torment my most sensitive spots. The real turning point came when he instructed us to strip bare, our skin flushing under his watchful eyes, and to share a sleek dildo—standing in for our trainer's imagined prowess. We took turns, our breaths syncing in rhythmic gasps, the fantasy blurring into raw need. There was no retreating now; the hunger had awakened something primal, and we craved the authenticity of flesh and heat.Fortune smiled on us as our therapist, sensing our desperation, finally shed his restraint, revealing himself just as our impatience peaked. What followed was a symphony of shared ecstasy—alternating rhythms of lips enveloping him, bodies yielding and claiming in perfect alternation. Savoring a cock, being filled and driven to the edge, it all transcended our wildest imaginings when we wove our pleasures together, turning rivalry into an intoxicating alliance.
