"Fucking ridiculous...!" Mitch muttered under his breath, grunting as he tried valiantly to get himself off. It was strange; it had never taken him this long to cum before! Why was it so difficult?
Rae giggled as she peeked around her bigger big brother's wide body. The pained expression on Mitch's face, driven by his jealous desperation, was priceless. She looked up at the back of Mike's head, and then tried to hug him as best she could. It was difficult, considering how tall and broad he was now. Her arms couldn't even reach all the way around, but she was able to at least run her hands over parts of his chiseled abs. She peeked again at Mitch, and smiled. "Hey, Mikey, I think Mitch is a little jealous! See how he's trying so hard to cum? I bet he thinks if he cums too, he'll grow just like you!" Rae watched as Mitch redoubled his efforts, cursing quietly under his breath. Feeling impish, she skittered around to Mike's front once more and pressed her body into him, pinning his cock between practically her entire torso, as well as much of Mike's. His mighty phallus was so big that it reached his mountain-like pecs! "Poor little Mitchy needs to cum so bad, but he's having so much trouble..." she cooed. She looked back up to Mike, who was smirking in Mitch's direction. "Maybe we could give him a little show? Help spur him along?"
Mike rolled his eyes, but before he could protest to the idea of helping his little brother, Rae had already started grinding her body against his cock, causing him to groan in satisfaction. If he hadn't had such a strong footing, he probably would've gone weak in the knees. Rae bent low to slide her brother's massive schlong between her tits. In the process, she stuck her ass out behind her, pointing it directly at Mitch. She gave her heart-shaped ass a little wiggle, hoping to catch her brother's attention. An increase in panting from behind her told her that she had succeeded, and she could practically feel Mitch's eyes glued to her butt.
Alrighty, Mitchy-boy, she thought to herself. Let's see what you have to give me.
And just like that, Mitch was able to cum. His eyes clamped shut as much-needed relief washed over him. It felt like he had cum buckets, but when he finally opened his eyes, he was actually disappointed to see that his sister's ass was sprinkled with an amount of his juices no more than what he was used to. And compared to her entire front, which was practically blanketed in his brother's ridiculous spunk, Mitch's load was, as Mike had suggested earlier, 'puny'.
Plus, he wasn't growing. He whimpered, unable to form words to express his sadness.
Rae giggled, and bent a little lower. She reached underneath the base of Mike's shaft and took one of his big balls in hand, and rolled it around in her fingers. The thing was so large that her fingers didn't even come close to wrapping around it. She rather enjoyed the heat radiating off of it, and she bent lower yet, so that she could lick it. "Mmm, Mikey... I'll bet you could cover me from head to toe with these cum-brewers you got here..." She kissed her brother's grapefruit-sized testicle, and gave it a few more licks. "Mitchy here couldn't even-- Eep!" She stood up straight, as a large meaty hand suddenly clamped down upon her sexy ass.
Rae's words got gotten Mike all hot and bothered again. He wanted to cum some more. He wanted to grow some more! He massaged his sister's ass for a few seconds, not caring that it was coated in his brother's juices. "Damn, sis, you really know how to get a guy worked up!"
Rae had a distinct sense of déjà vu as Mike spun her around and pushed her onto the bed. This time, however, she opted to roll over and face her brother head-on. She scooted back a bit and looked up at her big brother with a broad smile. From this angle, he seemed even bigger than he was. His thick, muscular body and massive prick made her all gooey inside, and she practically came on the spot when he grabbed her legs to stop her from getting too far.
"How would you like me to cum so much that there'll be twice as much Mikey for you?" he rumbled down to her, pressing his two feet of hard man-meat against her torso.
That's... an interesting idea... she thought whimsically, taking her brother's meaning out of context. She enjoyed his cock so much... The way it rested so heavily and hotly on her stomach and between her tits... As Mike began to buck his hips against her, rubbing his excessive shaft against her body and pressing his giant balls into her thighs, Rae reached for her BlueBerry and began typing a very special command... "Yeah..." she said, slightly distracted by her phone. "Cum on me... Cum in me, Mikey!"
Mike had been so close to another orgasm just from the sheer notion of growing larger, that it didn't take long for him to cum. He watched as an exceptionally voluminous rope of cum smacked his sister in the chin and splashed onto her tits. In keeping with her wishes, he withdrew a bit and pointed his still-cumming cock towards her snatch. It wasn't easy, considering how forceful and intense his orgasm was, but he managed to stuff at least the head and a few inches of his cock into his sister's eager sex.
Rae squealed as she felt her insides being blasted with hot cum. As he drove deeper into her she felt like she was going to split in half, but the pleasure was exquisite! Deeper and deeper he managed to thrust, as more and more cum erupted from his slit. She could feel the pressure building within her as her own multiple orgasms wracked her body; the volume of Mike's cum was exceptional, and she could actually feel it... stretching her! She looked down, and her eyes went wide as she so the soft swelling of her tummy. Of course, there was only so much she could take, and before long she could feel Mike's excess fluids squirting forcefully from her cooch, spraying and soaking her inner thighs as well as Mike's entire crotch - stomach, thighs, balls and all! Even after her own climaxes ended, her brother kept going, and she simply laid back and enjoyed the sensation of being filled to capacity with cum. When she felt him finish, though, she quickly regained her composure and backed up against the wall, sliding off of Mike's cock in the process. She... didn't really want him to be inside of her when his next stage of 'growth' overcame him.
Mike groaned, just as he had before, but from the start he could tell something was different. Way different. He couldn't feel himself growing taller this time. He couldn't feel his muscles flexing and tensing. And although what he was feeling was most certainly centered within his cock, he couldn't feel it stretching like he expected. He took it in his hands, and could immediately feel it growing fatter. Wider? It happened suddenly. He very intense but not painful sensation, his cock literally split right down the center. His eyes shot open to see what was happening, but it had already finished...
His dick, thankfully, looked normal. Both of them.
Before he really had time to register what he was seeing, a familiar sensation filled his balls, and he nearly went weak in the knees as he felt them swell and expand once again. Ignoring his twin cocks for just a second, he reached down with one hand and held one of his testicles, still soaked in his own cum. He felt it... enlarge. Grapefruit-sized balls apparently weren't big enough to service two cocks, and he moaned in pleasure as he felt grow heavier in his hand, stretching his scrotum further as they approached the size of small cantaloupes. Even when he turned his attention back to his cocks (which, naturally, were much more interesting), he could feel them pulling down from between his legs. It was a good feeling.
But I have two fucking cocks, he thought to himself, refocusing his attention. "I have... two cocks. Two." Shocked, confused, and utterly aroused at the sight, Mike raised both hands up to grip each cock - his left cock in his left hand, his right cock in his right hand. They hadn't grown at all like he was expecting them to, but having two of them sort of made him forget about that little disappointment. Experimentally, he slid his hands along his shafts. His eyes fluttered in pleasure as he moved down to their bases. They took up much more room between his legs than he was used to, but the extra mass from having two fat cocks and a pair of nearly-melon-sized balls was downright erotic.
"What the fuck?!" Mitch finally shrieked.
"Oh yeah..." Mike answered. "This just keeps getting better and better!"
"It sure does," Rae purred, scrambling up onto her knees so that she could get closer to her brother's twin pillars of twitching fuck-meat. "Look at you!" she gasped, hugging one of his cocks while stroking the other with her free hand. "Mmmm," she moaned in pleasure, licking one of his shafts, and then switching to the other. ""Twice the cock means twice the man! Mikey, you're amazing...!" Grinning coyly, Rae turned to Mitch, never letting go of her bigger brother's twin manhoods. "Don't look so blue, Mitchy-poo! You should be happy your big brother is getting everything you both dreamed of!"
This particular comment made Mike chuckle, but caused Mitch to go red in the face. "I... We never dreamed of this... This is just..."
"Fucking spectacular!" Mike finished.
"But... huh-how is this possible! It's... it's not!"
Grinning in triumph, Mike reached down to cup his sister's ass, and fondle it as she played with his impressive cocks. "Maybe I have magic cum and you don't," he said flatly, fighting back the urge to laugh at his brother's lack of fortune.
Rae's eyes lit up at the suggestion. Not a bad idea...
