Despite how many times she had sucked him off in all their years of knowing each other, Emily would never grow tired of hearing Andrew's gasps and grunts. The song of his pleasure filled her ears, egging her on, encouraging her to continue. Unrelentingly, she craned her head back, staring up at him to get her fix, as her mouth eased back and left his cock entirely, a popping sound emitting from the loss of contact. Her tongue saucily slid past her swollen lips and brushed against the tip of his member, before swirling around in small circles, spiraling and twisting lewdly along the perimeter of his mushroom head.<br/><br/>His words of encouragement stimulated her further, sending a rush of gushing liquid to sear her insides, a sensual grip tugging at her core, making her shudder against him, her grip on his base quivering momentarily. Sliding his length back into her mouth to continue bobbing up and down his thickness, only releasing his jewels and shaft when her jaw unhinged, to deep throat him as far as she could. Her hands spread over either side of his waist, to propel herself further, to force her throat to open wider, and take as much of his impressive size into her, as she could muster. The scent of her arousal only continued to lift into the air, slowly filling the room with a sensual musk, making obvious her level of desire.<br/><br/>Gagging gently, as her suctioned lips continued to suck him dry, willing his cock to twitch deep inside of her mouth, her ass cheeks tensed and tightened, as the muscles of her pussy clenched together. It had always turned her on so, sucking her brother, yet the crime of it all was that she often times couldn't finish him off, too needy for his thick meat to penetrate her confines, too impatient to wait until he got hard again. This time would be no different. Shoving herself off his rod, she pushed with her hands, which stabilized at his waist, gasping loudly for air when he was no longer filling her mouth to the brim. Bringing one hand to her mouth, she wiped the dribble from off her chin, licking her lips to savor the taste of his engorged cock-meat. Her lips fluttered against the protruding veins of his cock edges, sneaking a pleading look up at him. "Fuck me, Andrew, fuck me..." she whispered, her tone beyond sultry.
