**Chapter 12: The Bargain**

The air was heavy with anticipation as Emily followed the siblings to the living room, her heart racing with every step. The young man's sister, whose name Emily still didn't know, gestured for her to sit down on the couch, and Emily complied, trying to appear calm despite the turmoil inside her. The siblings sat down on either side of her, their eyes fixed on her with a mixture of desire and curiosity. The young man's sister reached out and gently took Emily's hand, her touch sending a shiver down Emily's spine. "We need to make one thing clear," the sister said, her voice low and husky. "We're not just talking about stress relief. We're talking about pleasure. And we want to make sure you're willing to give us that." Emily nodded, feeling a flush rise to her cheeks. She knew what they were implying, and she was torn between her desire to escape and her growing arousal. The young man reached out and gently brushed a strand of hair behind Emily's ear, his touch sending a spark of electricity through her body. "We want you to be comfortable," he said, his voice low and soothing. "We want you to enjoy this, as much as we do." Without warning, the siblings moved in unison, their hands reaching out to strip Emily's clothes off. Emily gasped as her shirt was pulled over her head, and her bra was unclasped, revealing her bare breasts. The siblings' eyes locked on her, their gazes hungry and adoring. The young man's sister reached out and cupped Emily's breast, her touch gentle but firm. Emily moaned as the sister's thumb brushed over her nipple, sending a wave of pleasure through her body. The young man, meanwhile, had reached out to undo Emily's jeans, his fingers deftly unbuttoning the fly and sliding the fabric down her hips. Emily felt a rush of excitement as her panties were pulled down, and she was exposed to the siblings' gaze. Their eyes roamed over her naked body, drinking in the sight of her. Emily felt a surge of self-consciousness, but it was quickly replaced by a growing sense of arousal. The siblings' hands were on her, fondling her, caressing her, and Emily couldn't help but moan. The young man's sister leaned in, her lips brushing against Emily's ear. "We want to make you feel good," she whispered. "We want to bring you to climax." Emily's body responded instinctively, her hips shifting, her breathing quickening. The siblings' hands moved in tandem, their touches weaving a spell of pleasure around Emily. As they fondled her, Emily's moans grew louder, her body arching towards them. The siblings' eyes locked on hers, their gazes burning with desire, and Emily knew she was lost. She was theirs, body and soul, and she knew she'd do anything to keep them happy. The young man's fingers slipped inside her, and Emily gasped, her body responding instantly. The siblings' touches grew more urgent, more insistent, and Emily felt herself being pushed towards the edge. And then, in a rush of sensation, Emily came, her body shuddering with pleasure. The siblings' eyes locked on hers, their gazes triumphant, and Emily knew she'd made a bargain she couldn't escape.
