The two weeks after the Sullivan family's first taboo threesome had been sex filled to say the least. Every weekday morning, Rachel had set her alarm 15 minutes earlier so she could suck on her son's cock while he slept until he filled her stomach with its first meal of the day. As much as she wanted to take his load inside of her pussy or ass, she knew it'd be a terrible idea to have a steady stream of his cum leaking down her legs during work but she couldn't stop thinking about it while sitting at her desk which inevitably made her pussy flood. At least she had all those pairs of spare panties to change into.
As good as his mom's mouth felt on his cock, James barely had the energy to wake up to say thanks then good bye to her while his sister slept next to him. The first few times mom sucked him off in the morning, he tried to return the favor but she laughed and told him to go back to sleep. She understood he needed the rest because she kicked Jess and him out of her room so she could go to sleep. The siblings headed over to one of their rooms and continued the antics well into the night. They understood mom had to go to work the next day and, much to their surprise, learned that trying to be as quiet as possible turned them both on.
A few hours later, James woke up to another mouth enveloping his already hard cock. Only fleeting flashes of his dreams remained but the memory of fucking some supermodel he followed on Instagram couldn't begin to compare with the actual sight of seeing his sister's full lips sliding down his thick shaft. He let out a grunt when her unnaturally shimmering lips touched the base of his cock. About a week ago she had gotten all dressed up in her cheerleading outfit and lip gloss had been the finishing touch. As soon as smacked her lips together and asked him what he thought, he pushed her to her knees and pushed the fat head of his cock between her glistening lips. Now, every morning without him even asking, putting on lip gloss was the last thing she did before taking him into her mouth.
Even with her mouth full of his flesh, she smiled up at him when he moaned to let her know he was awake. That didn't mean her mouth was idle though. Her tongue lapped at the underside of his member, making sure to focus her teasing on the sensitive bit where the head met the shaft, causing him to rock his hips just a little bit. In his still sleepy state, he only wanted to lay back and let his sister do all the work but he knew what she wanted.
The familiar feel of his sister's soft locks of hair surrounded his fingers as he took her head into his hands. He applied a small amount of downward pressure but his sister resisted and kept smiling at him while swirling her tongue around the crown of his cockhead. Grunting at the sensation, he forced her head down while thrusting up. Her eyes shot open as the tip of his cock touched the entrance to her throat then penetrated it with practiced ease on both their parts.
"God, you feel so good," he groaned.
Jess hummed in reply, sending shivers of pleasure shooting up his body.
As many times as he'd been inside of her throat these past few weeks, he knew he would never get tired of the tight, wet heat of it. It wasn't just about that though because the fact it was his sister whom he'd known for his entire life and loved with all his heart made the physical sensation almost meaningless. Almost. Even though she had resisted him at the start of this, her fingers were dug into his muscular thighs doing their damndest to help him fuck her own throat. By the time his hands stopped forcing her up and down, she had picked up the slack and was forcing herself up and down almost as fast thanks to the thick strands of her spit covering his cock.
James let his hands fall to the bed and his head drop back down onto his pillow to he could enjoy himself but after a few minutes he wanted to be able to look at his sister without craning his neck. Taking her head into his hands again, he forced her to stop when just the tip of his cock was inside of her mouth and she looked up at him.
"Take a deep breath," he said.
Her nostrils flared as she did and he found it cute in a way he never thought he could. After she finished taking in her breath, he pushed her down until her lips were touching the base of his wet cock again. She kept it buried down her throat even as he let go of her head then used his elbows to slide himself backwards up against the headboard of his bed. His sister didn't miss a beat and crawled up with him, her lips glued to the spot on his cock that he had pushed her down to. Though he had a much better view now, he waited to pull on his sister's hair to tell her she could continue but stopped himself and instead just took her head into his hands and held her there.
Jess knew her brother wouldn't let her actually choke on his delicious piece of meat. As rough as she wanted him to be, she knew he would never hurt her. That didn't stop her from trying to push against his hands though because the struggle was part of the fun. As she fought, her efforts and the growing lack of oxygen had her heart pounding. The uncontrollable panic rising in her only made her already throbbing cunt throb harder. The fading remnants of the salty taste of her brother's precum didn't hurt either. She desperately wished for the full flavor to fill her mouth again but the source of it was currently buried in her throat and all she could do was continue to work her tongue along his shaft.
Her palms slapped against his strong thighs and she tried to push herself off of him but his hands were much stronger and kept his cock planted deep in her throat. Just when she thought she might pass out, her baby brother pulled her off his cock and cleared her airway. Her body heaved as it tried to suck in the oxygen it had been denied a few seconds ago but before she could completely catch her breath her throat was filled with his thick cock again. Again and again, her brother took her breath away from her and each time it happened her cunt throbbed.
After a few times, his hips began to rock up and down when he held her in place, plunging the tip as far down as it could go. The familiar feeling of her lips being compressed against the base of his cock had her moaning around it, not because it felt good but because of the idea that her baby brother was using her mouth and throat as his personal, incestuous cocksleeve. A shiver went through her and her cunt clenched and gushed around a nonexistent invader.
The orgasm wasn't big and the lightheadedness from the lack of oxygen made it feel like a dream. When her baby brother's strong hands used her hair to yank her off of his cock, she gasped and air flooded into her lungs again. The sharp pain and sudden, full awareness of the sensations in her body transformed a soft, gentle orgasm into a toe-curling, screaming one. Never in her life had she imagined anyone, much less her own brother, could get her to cum from just giving a blowjob yet here she was unable to think about anything but the ecstasy coursing through her body.
In mid-scream, her brother pulled her mouth back down on his cock. Though she felt the tip pushing into her throat with ease and relished the feeling of it stretching her out, the pleasure ripping through her mind and body made her take a moment to realize why the screaming, her screaming, in the room had stopped. Finally, she came down from her high and her tongue automatically began to move when her brother pulled her up so just the tip of his cock was in her mouth.
Looking up at her brother, she looked up at him in with a contented, satisfied smile but a fire still burned inside her body. He looked down at her with a needy thirst and her cunt throbbed from it. His cock twitched and precum filled her mouth, confirming to her that he hadn't cum yet even with her throat vibrating in a scream around him for all that time. It didn't surprise her as her brother had the best stamina she'd ever seen but from how often his cock was twitching she knew he was close. Her tongue cleaned up every drop of her brother's salty secretions from the spongy head.
Her brother didn't need to tell her what to do because it was what she wanted to do too, knowing that every swipe drew him ever closer to giving her what she wanted. It was up to him though. If he wanted to fill her mouth, he'd let her keep going. If he wanted to fill another one of her holes, she'd be happy for that too because it meant she'd be getting fucked. Whatever he wanted, she'd gladly give him. Besides, she knew he'd probably fill all three of her holes sometime during the rest of the day and any hole he missed today, he'd get tomorrow. Or the next day. Or the day after one. Because they had all the time in the world.
