New author here, feedback is welcomed and appreciated.
This is the fifth chapter of a much longer story that will span multiple categories. The bulk of it will end up here under Incest/Taboo. This chapter, like others to come, involves a mix of encounters and not all are incestuous.
If anyone would like to assist with editing, I'm more than willing to accept help.
Thanks & Enjoy.

The Mentor
Alex heard a moan as he passed his elder sister's room en route to his own. A light was on and the door was ajar. He leaned in for a peek and was struck dumb.
Lily and Carrie were wrapped in each other's arms standing in the middle of the room, a mass of curly red and straight silvery blond hair. Their mouths were locked, hands running up and down. His sister's back was to him, she was topless and wearing the string panties that prompted his earlier search. He'd never seen his sister's bare ass before; it was far better than he imagined. She had an unimaginably narrow waist that dropped low before flaring out to remarkably wide hips. His crush's hands slid along her smooth pale skin, touching her in places Alex could only dream of.
Carrie was curvier than Lily, and a few inches shorter. She was thick but nowhere near overweight, her proportions perfectly fit her wider frame. Alex could see her ample breasts peeking around his sister's narrow torso, seemingly on the verge of spilling out of a white push up bra. She also wore a pair of satiny red panties that fit loosely except where they pulled tight across the impressively oversized hill of her Venus mound.
Carrie looked over his sister's shoulder, noticing the change in the light coming through the doorway. Exactly as she'd hoped, there was her little man staring through the doorway she'd conveniently left open. Eyes wide, he looked like a deer caught in headlights, not moving a muscle. She winked at him, grabbed Lily's ass tightly and pulled her cheeks apart forcefully. Lily moaned and buried her face into Carrie's neck, sucking and licking the soft skin below her ear.
Alex gawked apprehensively as Carrie spread his sister's ass, allowing the skinny string of her panties to become fully visible. She stretched her lover's pillowy cheeks so far that he could see the darkened rim circling her pink rose, split in half by the narrow ribbon. He stared through the wide gap between her legs, one of his sister's best features, and could see silky fabric arch out and cradle the juncture of her thighs.
Still looking at Alex, Carrie let one of her hands go and pointed at Lily's beautiful backside and gave a thumbs up while grinning like a fox. She took her free hand and ran it from the top of the vertical string through the valley of his sister's shapely pale cheeks. Down her finger went, pausing over her pink puckered star. Her index finger wiggled, riding the pink string back and forth across his sister's tight ringed hole. Lily moaned and started sucking on Carrie's earlobe as the mischievous redhead pushed harder on the string until it popped in. She let out a throaty moan while Carrie continued pushing until her finger was buried to its second knuckle.
Carrie slowly removed her hand, leaving the string in place, and shifted her grip around front. She palmed Lily's mound and slid her fingers into the heat deep between her legs. Alex could see Carrie's fingers stretched out between his sister's thighs, rubbing the small patch of fabric covering her pussy, first slowly, and then with more conviction.
Alex gaped in wonder at the ribbons protruding from his sister's cinched ring while she began thrusting her hips in rhythm with the hand between her legs. Carrie curled her fingers and pushed the pink material into Lily's wet opening. Alex didn't have the best view, but he could tell what was happening as he watched the panty fabric stretch and the string hanging out of Lily's tail begin to pull free. Carrie sunk her fingers into Lily's heat with force and the strands popped free and become one again.
Lily dropped to her knees, quivering with delight. Carrie put both hands on her platinum blonde hair and caressed the top of her head lovingly. Alex watched as his sister looked up at Carrie with lust and then pressed her face between the curvy redhead's legs.
What Alex would do to trade places with his sister. He watched Lily reach a hand up and pull the loose panties to the side and bury her nose and chin into Carrie's sex. The redhead gasped and then locked eyes with him and smiled, making a come hither motion with her hand.
Alex stood in shock, unable to move. His crush was being eaten out by his sister right in front of his eyes! There was no way he was going into that room, Lily would freak out. If she knew even a tenth of what he just saw she would surely make his life hell. Looking up at the enraptured redhead, he could only shake his head slowly. He mouthed the word "sorry" and backed away from the door.
Alex quietly crept into his room, shut the door silently, took off his clothes, and went straight to bed. Carrie definitely wanted more from him and the thought excited him beyond measure. He replayed the encounter in his mind and began gently caressing his stiffness. It went limp soon after, having nothing left to give for the day, and he soon passed into a frustrated sleep.
A vivid dream played out in Alex's semi-lucid consciousness. He was standing in a serene grass field, the sun shining down brightly. In a line facing him were all of the girls he'd been with recently. He slowly moved his gaze over each of them, starting with Sam, pointy nipples jutting from her flat chest, red lacy shorts hugging her hips. Then Becky and her beautiful dark-tipped breasts and stained black panties. Her twin Fiona stood next with a bulging chest, invisible pale nipples, and wet white cotton panties pulled into her slit. Then came petite Megan, perky breasts on display, wearing her nude tone bikini briefs and twirling a pink vibrator in her hand. Beside her stood his equally lithe and lovely little sister Casey, strapped into her white thong leotard, small nipples visible through the sheer fabric that pulled her puffy lips into a tight little bump between her legs. Lily was next, wrapped in Carrie's arms, wearing a pink g-string and red silky panties respectively. Carrie left his sister's grasp and walked towards him. She looked down and licked her lips at the sight his excitement. She reached out and lightly palmed his cock, then knelt and pulled him into her mouth.
Alex woke suddenly, his dream strikingly lifelike. He smelled strawberries and instantly popped his eyes open. He felt a warmth and softness on the tip of his cock that he had never experienced. A head was bobbing up and down between his legs! The feeling was beyond description as her tongue lashed out at his tip, circling its ridges round and round.
