Lily pt 4

The next day, Sam woke up to grunting sounds coming from his sister’s room. He slinked up to her doorway and saw her standing in front of a full length mirror doing shoulder flys with, amazingly, 95 lbs dumbells. She wore no top and a pink lycra bikini bottom that was nearly a thong in the back. It revealed most of her freakishly striated, angular glutes. Sam marveled that even there, at her ass, she had ugly blue veins and freakish vascularity.

Sam started getting hard as his eyes followed the bulbous, rolling muscles of her lower back, framed by obliques that bulged big enough to be seen from behind. With each rep, Lily’s massive upper back muscles, delts, and traps swelled and rolled as striations rippled across her massive frame. Her lats were like huge, thick meat wings that blew out under her arms when she lifted them up. At the top of each rep, her traps bulged so high they practically swallowed her head.

But it was when Sam looked at the mirror and noticed the front of Lily’s midsection that his cock stiffened hard as a rock. The front triangle of Lily’s pink lycra bikini bottoms was stretched out away from her waist, overburdoned and barely containing Lily’s huge, flaccid cock. Even flaccid, it was inhuman in size and shape, bigger than he had ever seen on any dude.

Sam saw Lily’s face in a contorted snarl, as thick blue veins bulged on her forehead and even in her cheeks. Between grit teeth, she hissed, “Twenty-five…” as she powered up another rep. Then she noticed Sam behind her, staring at her massive frame, awed, his obviously rock-hard cock standing at attention. The corners of her snarled lips turned up in an appreciative, aggressive grin.

Upon seeing the effect of her super-pumped physique on her brother, Lily was instantly turned on, and felt energy coursing through her already super-charged muscles. She powered through another rep, increasing her speed, feeding off the horny energy of her brother’s untowered lust. She felt her own loins engorge, and her flaccid cock started to inflate. 

The thin side strips of her bikini bottoms audibly stretched as the head of her engorging cock stretched the material to its limits. Lily grunted, hefting another rep, and her cock-head surged forward with angry lust. The lycra audibly stretched and snapped, causing the bikini bottoms to explode off her hypertrophied, monster-body. 

Sam’s chin dropped in amazement as his sister’s massive she cock tore free of the lyrca bikini bottoms that just could not contain it. Lily smiled a huge, shit-eating grin, powering up another rep, then another, as Sam watched her seemingly endless capacity to push her muscles harder, to pump them up further. Sam couldn’t help himself. He reached down and stroked his cock at the inhuman, she-monster beefcake his sister had become.

Lily chuckled, then eyed her monster she cock approvingly. She grunted and it seemingly stretched out, throbbing higher, reaching toward her vein-crusted lips. She stretched her neck and opened her mouth wide, cupping the top of her massive member. She moaned and Sam nearly came right then. She continued her shoulder flys, only each time she brought her arms up, her head bobbed down, sucking on the head of her thick prong, and her hips bucked, sending her cock deeper into her face. Her traps, lats, and delts surged with each bob of her head, as if her roid-pumped she-cock were inflating more mass into her already hypertrophied musculature.

Again and again, she pumped her arms and sucked her cock, grunting wildly, increasing her speed, as Sam audibly moaned in lust at the sick, lewd display in front of him. Lily pumped and bobbed, again and again, and her muscles bloated sickeningly. She started screaming muffled grunts as she thrusted and pumped, one, two, three more times, then she suddenly slammed the weights higher and shoved her head down. Every muscle on her freakishly butch body vibrated and throbbed as her cock bucked and unleashed a torrent of jism into her mouth. Sam could hear the gulps as Lily swallowed greedily. Her traps, delts and lats bulged and throbbed, seemingly growing right before Sam’s eyes, like they were being pumped up with Lily’s own cum. 

Lily suddenly dropped the weights with a huge crash. With a final groan that sounded more male than female, Lily released her cock, which swung down from her face and slapped audibly against her over-muscled leg. She turned and looked Sam in the eye, then smiled lewdly. Sam could see the spaces between her teeth filled with thick white cum. Lily’s thick tongue snaked out and lapped across them, sucking every ounce of cum into her mouth. Then she swallowed with a huge gulp.

“Enjoy the show?” she said with a chuckle as Sam stroked his cock furiously. "Because I'm just warming up!"

Then she bent down into a most muscular pose. Her thick pecs throbbed and bulged, and her grapefruit-sized biceps bulged, pressing into them. That sent Sam over the edge and he came with a grunt, spewing cum all over his sister’s pecs.

“Ha ha ha,” Lily chuckled, feeling her own libido rise at her brother’s lust and messy orgasm. “I’m fucking HOT, aren’t I?” she said. Then she reached down and grabbed her own inflating member.

“Unngh,” she moaned as it bucked and lengthened, reaching the height of her pecs. “So horny!”

Sam’s eyes widened, taking in the sheer size of her erect clit-cock. 

“Don’t worry,” Lily said with a chuckle. “I’m not going to fuck you with this thing,” she said, stroking it faster. “Ha, if I tried, I’d tear you in half!”

Sam blinked, speechless.

“Don’t worry, bro,” Lily said nonchalantly. “I can take care of myself!”

Then she bucked her hips and her thick member slapped into the cleft between her pecs. She flexed them and they bulged, trapping her thick clit-cock between them. Smiling madly, Lily bounced her pecs, massaging her cockhead.

“Ohhh yeahhhh” she moaned. “Bet you wish you could do this!”

Then she flexed her abs and those thick blocks bulged, massaging the top of her clit cock. She bucked her hips, moaning, as she fucked her own muscles, slowly at first, then faster.

“Oh fuck YESS!” she cried, pistoning her cock over her cobblestone abs and into the massive cleft of her pecs. Her arms pointed straight down, hands balled into fists, and Sam could see the veins engorging on thick, muscular forearms and massive, gnarled triceps bulging out. Her biceps bulged inward, pressing against her pecs, adding more pressure against her clit cock.

“I’M SO FUCKING HUGE!” Lily cried, bucking wildly. “I’M A HUGE, HORNY BEEFCAKE!!” she cried. The head of her clit cock expanded and turned purple. Lily suddely released it, then slammed her cock into her own face. She came with a muffled roar, gulping her own cum furiously.

Sam was hard again, already, watching the incredible eroticism of his sister eating herself. After what seemed like minutes, she finally released her clit cock, and it slapped down against her thigh. She licked her lips.

“Still enjoying the show?”
