The daily routine and quality of life sure had changed for Colin Moore since his sister Kayleigh had moved in with him a three weeks ago. Prior to that, a typical night for him would consists of coming home from work, ordering pizza, and playing computer games and masturbating to porn all night.
The only thing that was the same was that he still ordered pizza frequently. Almost everything else had changed.
He woke up this morning not to the sound of his alarm cock, but instead he was awoken by the sensual feel of his sister's lips wrapped around his cock. He woke up every morning with a semi-hardon and since Kayleigh usually woke up before him, she made sure that semi-hardon turned into a full erection. She loved waking him up with blowjobs.
Colin looked down as he lay in bed and watched his blonde sister suck on his prick. His dick was fully hard this morning and she was happily sucking him off in bed. His little sister had blossomed quickly into a gorgeous babe. She had bleached blonde hair, a nice tan, gorgeous lips that were full and plump, and a set of big, fake F-cup tits that made people stare wherever she went. Kayleigh had a body and complete image of a barbie doll porn slut. She'd make a great porn star, but what she really aspired to be was a lingerie model.
It didn't take long before Colin's prick was dripping wet as Kayleigh sucked and drooled all over him. She looked up at her brother as she flicked her tongue over the slit at the tip of his cock, where his precum had been steadily oozing out. Her tongue was soft, warm, and wet as she let it glide over the swollen end of Colin's cock. Seeing that he was awake and enjoying the affection, she smiled up at Colin, flashing her bright white, perfect teeth which were framed by full, plump lips and said "Good morning!"
"Morning, sis. That feels goooood!" he said. Kayleigh was now smacking his penis up against her lips, giving it a kiss each time the shaft thwocked up against her face.
"I know my big brother loves morning blowjobs!" she said happily.
Colin felt how wet and slippery his prick had become, and he had a great idea. "I sure do, but this morning I think I want to fuck those big tits of yours."
"Yeah!?" Kayleigh squealed in excitement. Ever since she got her boob-job, she was addicted to using them and receiving attention focused on her breasts. She loved hearing Colin talk about how much he loved her massive tits, and whenever they were out in public she wore tight, low-cut shirts to expose gratuitous amounts of cleavage, she had an almost unquenchable crave for the lustful stares she drew from just about everyone. She soaked up the attention her boobs got her and she loved it all. She needed to have eyes on her, and she loved the gawking stares she drew, not just from her brother, but from everyone. "I'd love to milk your cock with my boobies." she told Colin. Most of all, she loved to use her new set of jugs to tittyfuck.
Kayleigh scooted down off the bed and knelt near the foot of the bed, as Colin slid down so he was sitting at the edge. She placed her hands on the insides of Colin's thighs, leading him to open them a little further, and once he was spread nice and wide, she moved closer to her brother. Colin's member was arching up eagerly and was still dripping with drool, and soon it was being pressed up to Kayleigh's firm tummy. Once she let the penis make contact with her body, she started to slide down further, so that the smooth underside of his shaft slid along her body until it was positioned perfectly between her breasts.
All Colin did was lean back on the bed, and he even used a couple pillows to help prop himself up as he leaned back on his elbows. What a life! His little sister did all the work from here on out. His blonde sister placed her hands on the outside curves of her swollen boobs and squeezed them together, trapping the slippery rod in between them. Colin's prick was wrapped up tightly in Kayleigh's titflesh as she squeezed those gorgeous boobs around him. They were the perfect size for tittyfucking. Kayleigh's jugs were just made for slapping a cock between.
Colin started to pump his hips upward, sending his shaft sliding through her cleavage. Even with his hips pumping up and down, Kayleigh lifted and lowered her boobs up and down too, fucking Colin's shaft with her round, ballooning bubbles.
On Colin's bedside table was a half-full bottle of baby oil that they had bought a few days ago. Once they had started using it, it became really hard to not use it. So even though Colin's prick was still wet and slippery from Kayleigh blowing him earlier, he yearned for that bottle of baby oil just a few feet away. Adding the baby oil to a tittyfuck made it so much better.
"Hold on, Kay, let me grab the oil." Colin said, leaning back. He reached as far as he could and was just barely able to grab the bottle with his fingertips without having to let his cock slip out from his sister's incredible rack. It was probably the most impressive physical feat he had ever done.
With the bottle of baby oil in his hands, Colin removed the cap and then squirted a stream of the warm liquid up and down his shaft until it was coated and slick. Next, he turned the bottle toward his sister's rack. He started at her right nipple and squirted the slippery oil back and forth across her boobs, soaking them with the lubricating liquid. Now that they were slick and slippery, Colin set the bottle aside and started humping his hips again.
"That baby oil feels so good on my boobies." Kayleigh said sweetly, as she felt the warm liquid soaking into her bosom.
"Good, I know, it makes it so much easier to fuck your tits, too!" the older brother replied.
It certainly did help him tittyfuck Kayleigh. As he moved his hips up and down, Colin's prick was able to glide with ease up and down between Kayleigh's big, perfectly inflated tits. Her boobs were smushed slightly as she squeezed them together hard, and they created a tight mold around his hard cock. Kayleigh's little hands couldn't grasp her tits without them overflowing. Her ballooning jugs simply were too big for her to cup in her hands, but she could push on the outer curves of them to squeeze them around Colin's dick.
Kayleigh raised and lowered her rack up and down her brother's slippery cock. They were gliding together so easily now and the motion of Colin fucking her boobs was making slurping noises in the bedroom.
The busty sister didn't need him to warn her that he was about to cum, she could sense it was coming. As Colin started to cum, his first rope of jizz squirted from the tip of his cock, flying up from between Kayleigh's boobs, and then it landed on the top of her swells. He kept his dick buried in between her melons and she continued to massage his prick with her orbs during his intense orgasm. Colin's next two blasts of semen were delivered between her breasts in a gooey mess. Finally, he finished by pulling his dick out and squirting his last drops of cum across one of her nipples. His white, gooey sperm was dripping down over her tan skin.
Kayleigh crawled up onto the bed, her bosom slick and dripping with cum, and relaxed on her back beside Colin. He absolutely loved that he and Kayleigh had become so close and intimate that he was fucking her boobs on a daily basis, but he longed for more. He wanted to take things to the next level. The problem he had run into was he had convinced Kayleigh that it was okay to do what they were doing because it technically wasn't incest. In doing so, he had basically drawn a line of what was on and off limits. It was ironic then, that exactly what he had defined as off-limits was exactly what he was craving the most.
He really loved the blowjobs and titjobs, but more and more often he found himself wanting to slide his cock inside her pussy and fuck her. He had painted himself into a corner, figuratively speaking.
Just then, Colin noticed the clock on the bedside table. "Holy shit, I'm an hour late for work!"
After throwing on some clothes and getting a kiss goodbye, Colin flew out the door and ran to work. His job was at a deli just a few blocks away, so he was able to walk to work. Despite being so close, he had been late almost every single day for the past few weeks. These morning romps with Kayleigh were great, but he always lost track of time.
Once her brother left for work, Kayleigh curled back up in bed. Her tits were still a slimy mess of baby oil and jizz, but she liked leaving Colin's cum on her breasts for a while. Usually if she gave him a titfuck before he left for work, she'd let his load stay splattered across her breasts for a good hour or two, letting the fuckjuice soak in, before she'd clean up. It felt nice. She felt validated when she was coated in sperm.
Kayleigh opened her bedside table drawer and pulled out her pink dildo that she kept there, and she started to play with herself in bed. She only had enough time this morning to make her brother cum, and now that she was alone she would spend the day in bed playing with her pussy. The toyed with the dildo, imagining that it was Colin's cock.
"Oh Colin, why don't you fuck me?" she whispered to herself as she steadily pushed the dildo inside her pussy.
