Adam enjoys Cindi's cock hungry attention...

Adam leaned back against his aunt’s soft body with a growl of satisfaction as Cindi’s full lips wrapped firmly around his throbbing shaft. His need to fuck and impregnate his three family members was stronger than ever, despite having cum several times already since dinner had begun. Was his constant intake of Gorgon extract still changing him? So what was he becoming other than a walking hard-on?

His skin tingled pleasantly under Pamela’s caress and he could feel her hips grinding up against him as she tried desperately to relieve her own carnal desires as she watched Cindi lick and slurp at his massive tool. His face split into a wicked grin as he ran a hand down through his little sister's long golden hair and enjoyed the feel of her tongue working ardently over the head of his straining cock.

“Oh yeah Cindi…” Adam murmured closing his eyes and leaning heavily back into Aunty Pamela’s groping embrace. “God you’re such a good little cock-sucker.”

His younger sister just gave a pleased moan and sucked more of him into the warm wetness of her mouth taking him all the way to the back of her willing throat.

Adam wasn’t sure how much more of his foot long pole she could take in when she swallowed the top inch of it with a smooth gulp. His eyes shot open again and his legs jerked with a shock of pleasure that shot through him as she swallowed again taking more of him down her throat. Like a trained sword swallower she arched her slender back and straightened her graceful neck over his aching groin, sliding her soft full lips down the length on his meaty shaft as she took all but the last 2 inches down her hot tight gorge.

Adam's face was a confusion of shock and ecstasy as Cindi snorted air through her nose and began to move her head smoothly up and down on his monstrous manhood. He heard his Aunt gasp in disbelief and his hips jerked up involuntarily as the underside of his cock-head rubbed sensationally within her esophagus.

“Jesus Cindi!” Adam gasped in wide-eyed admiration “Oh god yes! Suck it, suck it all!”

Her delicate fingers dug into his meaty thighs as the smooth piston-like motion of her head and neck became faster, her snuffling breaths more labored and Adam rested one hand lightly on her neck, feeling the muscles there strain and writhe as she took all of him down into her throat. The sensation was new to him and fucking incredibly!

Her gullet tightened and quivered around his meat as she sucked it down towards her waiting belly, it was slick and hot and sent lightning bolts of rapturous delight up his spine to explode behind his widening grey eyes. He wasn’t sure how long she could keep this up… he wasn’t sure how much longer he could endure it!

“Oh my god…” whimpered Pamela from where she stared over his broad shoulder, her hands moving faster between her smooth thighs, “It’s not possible!”

Cindi’s great heavy breasts swayed pendulously under her writhing body like two massive udders and Adam's hands shook with unrestrained pleasure as he reached under her to grasp at them eagerly. Her nipples were larger now, longer and hard as brass, he pinched them cruelly making his little sister shudder and moan around her throatful of suffocating cock. Her abundant tit-flesh overflowed even his large hands as her groped and kneaded them hungrily, rolling her sensitive nipples across his rough palms.

“Cindi, I… I’m going to…” he moaned but it was too late for any warnings, with unexpected suddenness he erupted straight down her straining neck.

She jerked as he blasted something that felt like a missile volley down towards her waiting stomach and he seized her head in both hands, forcing it down his flagpole of a cock until her lips were kissing the very base of it. She grunted but didn’t fight as he came, howling exultantly straight down her tight convulsing throat in eruption after long eruption of hot sticky seed which his sister swallowed ravenously with muffled moans of satisfaction.

When it was finally over and his head began to clear Adam pulled his cock gently back from between her full lips. She gave it a final soft suck and the head emerged from that amazing mouth with a light pop.

Cindi coughed and wheezed in a long breath of air, Adam gave her beautiful young face an affectionate caress looking down at her with a loving smile.

“You are amazing lil’ Cindi…” He said gently, then eyeing her up and down added “…Though I’m not sure I can still call you that.”

She just coughed again and looked up at him with those big sparkling worshipful eyes.

“You can call me whatever you like bro,” she said in a shaky tone that became stronger as her eyes grew more ferverent once again, “Please, just never stop fucking me!”

“…fuck meeee…”

The tone of the whisper was urgent and pleading. Adam craned his head to look back at his Aunt Pamela.

She was pressed hard against his back writhing up her gorgeous soft body up against his back desperately with one arm sandwiched between them, hand down between her legs. Her long mane of autumn red hair was a mess and her eyes were wild but she was no less beautiful for that.

Adam's cock was still hard, even harder than before if that was even possible, and he slid his body around to face hers. His eager hardness met her willing softness and her rosy bee-stung lips parted in a shuddering moan of anticipation.

After all she was becoming something more… more… more…
