Noah had been watching TV on the couch with his father for the past hour or so. After a yawn and a quick stretch, he stood up.
"Tapping out, pal?" his father asked.
"Yeah. I'm kinda bored. I might head over to a friend's house." Noah answered and began to walk up the stairs.
"Well, alright. Just be sure to check on your sister before running off," he called after him before turning his attention back to the TV.
Once upstairs Noah knocked on his sister Alicia's door, hearing a 'Come in" before opening it.
"Hey sis, Dad asked me to check up on you. Everything alright?" Noah asked as he leaned against the door.
"Hi, Noah! I'm alright, I'm playing with my toys!" She replied playfully, waving a doll at him.
"I can see that," he said as he looked around the room.
He saw the usual amount of toys and clothes strewn around from whenever she played dress-up. Taking a look back at Alicia he realized that she wasn't wearing any pants, just her panties and a shirt.
"Uh, why are you playing in your undies?"
"Oh, I'm using my pants as a tunnel. See?" She said and pointed to them.
The pants were lying in front of her and appeared to be stuffed with quite a few of her toys, a doll's legs could be seen sticking out of one of the pants legs making Noah laugh a little.
"Ooh, did you wanna play with me Noah?" she asked, holding up and male doll for him to use.
Noah did want to go to a friend's house but knew this could lead to something far more entertaining.
"Alright. I guess we can play for a little while." he agreed and accepted the doll.
"Yay!"
"Wanna sit on my lap for this?" he asked as he sat next to her and the toys.
She nodded and sat on his lap, her butt resting right on his crotch.
They sat and played with the dolls for a few minutes. Noah started resting his hand on Alicia's hip at some point. He never realized how much she moved around while playing. Every twist, every bounce, every rub, it all slowly added to his arousal. Soon a stiff bulge had grown in his pants. There was no hiding it, especially when Alicia could already feel it.
"Is that your thingy poking me in the butt, Noah?" she asked, turning around a bit to ask, inadvertently grinding on his bulge again and adding to his arousal.
"Maybe. I think it wants to play too." He said, grinding his bulge against her.
"Oh yeah, I wanted to tell you I've been playing our games with my toys," Alicia said with another bounce.
"What have you been doing with them exactly?" Noah asked, growing a little curious.
Alicia took the male doll from Noah and then undressed both of them, surprising Noah just a little. She put the male doll on top of the female one and began moving them around to make it look like they. She put them in a few different positions, only the ones she knew for being with Noah.
"It makes them feel good. Like how you make me feel good when we do it." she giggled, making the dolls hump each other a final time.
"Speaking of feeling good..."
Noah had the idea to lift Alicia off of him and lay her on her back, catching her off guard. He placed his hands on either side of her and leaned down. He pressed his bulge against her panties and rubbed it against her mound, getting a soft moan out of her.
"You did make me hard. You mind helping me out?" Noah asked and pressed the tip against her covered slit.
Alicia reached down and placed her hand over it, rubbing it firmly and grinding against the tip. Noah let out a gruff moan before getting up. He stood and dropped his pants, letting his cock hang free before her. Alicia got up on her knees, coming face to face with it. She wrapped her small hands around it and began stroking his shaft.
Alicia loved playing with his cock. It was so big and warm, she could just barely fit her hands around it. It was her favorite toy. Just don't tell her other toys that. She tightened her grip on his cock and stroked faster, bringing her mouth to the tip to lap up the bead of precum that formed, causing Noah to let out a heavy breath.
"Fuck. Good girl, Aly." Noah said breathily and placed his hand on her head.
He moved her head closer until his tip pressed against her lips. She happily opened her mouth and allowed the first couple of inches inside. She wrapped her hands around the base of his shaft and began bobbing her head on it, sucking hard while doing so.
She continued to stroke his cock as she took more of it into her mouth, the tip prodding the back of her throat. It always impressed Noah how much of his dick Alicia could swallow. He was far from small, and Alicia was still rather small due to her age. The girth alone would even give an older woman a challenge. That never stopped her from doing her very best when pleasuring her big brother.
A couple of minutes had passed. Noah bit his lip and shut his eyes tightly. Between her soft hands and her warm, slick little mouth, he was on the verge of blowing his load. Her sweet slurping sounds certainly didn't help. They were like heaven to his ears and only pushed him closer.
He tilted his head back and moaned out. While doing so, he noticed that he hadn't fully closed the door after coming in. He was a little alarmed at first. What if their father had heard them? He was about to pull out, but then an idea crossed his mind. What if he...
It was outright insane. It could go beyond horribly wrong, but in his horny state of mind, he didn't care. All we wanted to do was fuck his little sister and cum.
He pulled his cock out of Alicia's mouth, much to her disappointment.
"Aww, why'd you stop? You were getting shaky and were about to shoot that gooey stuff." she pouted.
"Don't worry, we're not stopping yet. I just want to finish inside of you," he answered and helped her to her feet. "Panties off."
Alicia obliged and slid her panties down before kicking them to the side, making sure to wiggle her butt for him and give him a good view. Noah gave her rump a nice firm squeeze before kicking his pants aside and leading her to the bed. She sat on the end of the bed and watched with an innocent smile as Noah stroked his cock in front of her. While waiting for what would happen next, she happened to glance over at the open door and let out a gasp.
"Wait, Noah. The door's not closed. What if Daddy finds us doing this? You said we can only do this with the door closed." she warned, a hint of worry in her voice.
Noah didn't respond, he simply kept stroking his cock, only leading to Alicia's confusion.
"Noah?"
Without a word, he abruptly pushed Alicia onto her back, spread her legs, and plunged two of his fingers deep into her little cunny. Alicia cried out, caught by surprise, but enjoying the sudden intrusion, before covering her mouth. Noah used his free hand to move hers away from her mouth. He gathered the other one and pinned them both above her head with a single hand, not once removing his fingers from her slit.
He curled his fingers inside of her, rubbing all the right places. With nothing to muffle herself, Alicia had no choice but to moan out and ride her brother's fingers. He flexed them within her a final time before slipping them out of her. Noah had an almost evil grin on his face as he inspected his digits. They were coated in her slick honey. He stuck them into his mouth and licked them clean, not missing any of it.
It was time for the real fun to begin. Wasting no more time, he gripped his cock and pushed the tip in, and slid it along the length of the opening, coating it in her young juices. Alicia bit her lip and tried her hardest to control her breathing and volume. The heat she was feeling in her cunny was indescribable. She was beginning to get really wet anticipating having her brother's huge cock inside her.
Noah gripped her hips tightly with both hands, and with a smirk, and no warning, he rammed his entire length into her small cunny with a single thrust. Alicia cried out again, not bothering to quiet herself that time.
Noah usually started off gently whenever they had sex. Not this time.
He pulled back until just the tip was inside of her, then slammed it all the way back in. He repeated this until he had a steady rhythm, giving her long, deep strokes. All Alicia could do was grip her covers as he used her, moaning cutely as she got wetter as they continued, getting his cock nice and slick for easier entry.
Noah's thrusts got faster. The wet sounds of her pussy and their bodies connecting filled the room. The open door had been completely forgotten in Alicia's mind. And for Noah, it added a wonderful spice to the whole encounter knowing that their father could potentially hear them and come and catch them in the act. His own son mercilessly pounding his daughter.
It was so devious but felt undeniably good.
Just the thought of it was bringing Noah close to climax again. He could feel Alicia shaking and tensing up, she was almost there too. Noah doubled his efforts, thrusting as hard as he possibly could and as deep as his cock could possibly go inside of her. If their father didn't hear them before, he would definitely hear the creaking bed above him. In hindsight, he could have gone easier on her. She would definitely be a little sore afterward, and probably him as well. But at that moment they couldn't care less, it all felt too good.
Alicia was the first to reach her limit. Her eyes shut tightly as she called out Noah's name in ecstasy and wrapped her legs around him, holding him in as close as she could. Her walls clenched and spasmed around his shaft, coating it with her flowing juices and wetting the bed.
Noah gripped Alicia's hips hard enough to where it would surely leave marks later. He thrust into her a final time, pressing the tip right against her cervix as he let out loud, throaty moans and shot rope after rope of brotherly seed into her womb until it could hold no more, some seeping out of her abused flower. He slipped his cock out of her and jerked off, shooting the rest of his load on her pussy and tummy.
They both remained there for a few minutes breathing heavily, Noah had yet to let go of Alicia.
"Fuck. Now that felt amazing. Right, Aly?" he asked, being the first to speak up.
Alicia didn't have it in her to answer, she was panting while her body was still trembling from her orgasm. Noah laughed, feeling rather proud of himself. He wrecked her good.
"Maybe you could teach your dolls that," he said while massaging her hips.
Downstairs sitting on the couch was their father with his cock in hand. There were streaks of cum on the floor before him and some on his hand and couch. He had heard everything. Disbelief couldn't even begin to describe what he was feeling, but it certainly wasn't the only thing he was feeling.
"Damn kids..." he panted before beginning to stroke his cock again.
