It was a normal day for the Richardson’s. Thirteen-year-old Jason woke up and threw the covers off of his naked body. He gently rubbed his growing cock and sighed. It was Monday; he had to go to school. As slowly as he could, he got out of bed and strolled downstairs to the kitchen, not even thinking about putting on clothes.     His sixteen-year-old sister, Janessa, was already sitting at the table, and his mother, Kim, was making breakfast. Like Jason, neither of them were wearing anything. The only one dressed was their father, but that was because he was going to leave for work pretty soon.     "So mom, I think I'm gonna invite my friend over this afternoon," Janessa said. "I've been talking to her lately and I think she would like to meet us." She looked at Jason. "I think you'll really like her, too, Jay."     Jason blushed. His cock was starting to get hard and he wanted to hurry and eat his breakfast so he could go jack off. "I think that's a fine idea, Nessa," Kim said as she stacked pancakes on their plates. When she got to the empty seat at the table, she filled the plate and yelled "Ellie! Come on, honey, we're going to be late." Pretty soon, eleven-year-old Ellie walked into the kitchen. She was rubbing her little hairless pussy.     "Sorry, mommy," Ellie said. "I'm really wet right now and I need to cum. Jayjay, can you help me?"     "Not at the table!" their mother scolded. "Finish your breakfast first.     "Ok, mom," Ellie and Jason said together. She sat down and started eating her pancakes. While they ate, their golden collie, Laddie, came into the kitchen. He sat down next to the stove and looked up at Kim. She started petting him and gave him a piece of bacon. He quickly ate it and started sniffing around the table. When he went under the table, he found Ellie's young little pussy and started licking it. Ellie jumped in shock, but then started shivering in delight. She petted his head and coaxed him to stay. Janessa and Jason looked at each other and started giggling.     "What's going on," their mother asked. She turned around and saw Laddie under the table. "No Ellie!" she scolded. I told you not at the table." She grabbed Laddie's collar and pulled him out from under the table. "He will be waiting for you when you're done. Just finish you're breakfast; we're running late."     "Sorry mommy," Ellie said. She quickly ate her pancakes. When she was done, she got up and started walking to the living room. "Come on, Laddie," she said. He stood up and ran behind her. They headed to the sofa to finish what they had started. Janessa was the next to finish. She got up, put her plate in the sink, and went upstairs to get ready.     "Well, time for me to head off," their father, Jack, said. "Bye, sweetie," he said to Kim and gave her a kiss. When he walked passed Jason, he ruffle his hair and said, "Bye Jay, have a good day at school." Then he walked out the door.     "Hurry up Jay, you need to finish you're breakfast so you can get ready on time," his mother said as she left the room. He quickly finished his pancakes and then left the kitchen. As he walked through the living room, he saw his little sister sitting on the couch with her legs spread apart sticking straight up in the air, letting Laddie lick her pussy and ass. Her eyes were closed and she was petting his head, moaning, "Oh yeah, Laddie. Good boy." Jason smirked and started climbing up the stairs. He got to the top and walked by the bathroom. The door was wide open and his older sister was inside, sticking the handle of her hairbrush in her dripping-wet pussy. Her eyes were closed and she was moaning loudly. He didn't want to disturb her, so he walked passed her, lifted the seat to the toilet, and started peeing. She jumped in surprise when she heard him, but quickly went back to masturbating with the hairbrush.     "Oh, Jayjay, when you're done, can you help me?" she asked. "Sure, sis," he said. When the last drop of pee was in the toilet, he flushed it and walked over to Janessa. "What do you need, Nessa?"     "Oooohhhhh Jayjay," she moaned. "I need it in the ass. Could you fuck me really quick?"     "Sure thing, sis." He grabbed the bottle of lube that was on the counter and covered his cock with it. He started stroking his cock with one hand and he used his other to put some lube on Janessa's little pink butthole. When his cock was hard, Janessa stuck her butt out for him and he shoved his cock up her hole. It slid in easily and he started fucking her fast and hard. She shoved the brush handle farther in her pussy and moaned loudly. "Oh yeah fuck my ass, Jayjay! Fuck me with your 13-year-old cock!" He squeezed her asscheeks and pushed as far into his sister as he could. He reached around and started fondling her perky tits as well.     "Oh yeah that's it Jayjay! I'm cumming!" Janessa screamed and her pussy juices started running down her legs and onto the floor. Jason came too and filled his sister's ass with his warm sperm. He shot more and more of his load into her until his balls finally emptied. They both sank to the floor. "Thank you, Jay, I needed that," Janessa said.     "No problem, anytime," he answered. Then they realized what time it was and started getting ready for school. They gave each other a quick kiss on the lips and went to their rooms to get dressed. When Jason was ready, he went downstairs where his mother and Janessa were waiting for him, both fully clothed. Ellie was still naked on the couch, watching TV with Laddie resting at her side. Her school didn't start for another half hour, so she didn't have to get ready as early.     "You two ready?" their mother asked.     "Yup," they both said. "Bye Ellie."     "Bye," Ellie replied. Then they went out to the garage and piled into the car. Janessa was a sophomore in high school, and Jason was a seventh grader, so they were going to different schools. First to get dropped off was Janessa. They pulled into the parking lot and she opened the car door. Before she got out, she looked at Jason.     "Ok, Jay. I'm gonna bring my friend Lily home with me today; she wants to meet the family. She's really nice and I'm sure you'll like her. So be ready when I get home; naked is fine." She gave him a wink.     "Ok, I will. Bye Ness."     "Bye Jay, Bye mom." She closed the door and they pulled out of the parking lot. ***     "Laddie, I'm home!" Jason yelled. The collie came running at the sound of his voice. He licked Jason enthusiastically and then started sniffing him. Jason laugh. "Just hold on a minute, boy." He threw his school stuff down on the couch. Jason was the first one home. He walked home from school and arrived at two thirty every day. Janessa got home just a little bit later, and Ellie got home at three. Since they worked, both of their parents got home at around five.     Since Janessa would be home any minute, Jason ran straight up to his room. He threw off his clothes and put them on his bed. He was anxious to meet Janessa's friend. It was seldom that they actually had company, and when they did, they always got dressed and acted normal around them. This was going to be a change for them. He wondered how Janessa even convinced Lily to come over in the first place. Did Lily even know what she was getting into? Well, regardless, Jason was going to fuck a complete stranger, and he was both excited and nervous. He needed something to pass the time, so he laid his belly on the bed with his knees still on the ground and stuck his butt out.     "Laddie!" he yelled. Within a few moments, the collie came running. When he saw Jason's bare ass sticking out, he knew what to do. He walked over and started licking Jason's balls and ass. He instantly let out a huge moan of pleasure. Jason loved to have his ass and balls licked. Laddie's rough, warm tongue and hot, sticky saliva felt amazing. He closed his eyes and imagined it was his little sister, Ellie, licking him. Ever since she was little, Ellie had given the best blowjobs, but she had never licked Jason's little pink butthole before. The only one in the family that had done that was his mother, who would lick his tiny cock and balls as well when he was little to get him to sleep.     Jason was well into his fantasy when he heard the door open. Laddie stopped licking and looked at him. He stood up and said, "Go, boy," and Laddie ran downstairs to greet Janessa. He figured Janessa would call him when she was ready, so he sat on his bed and started rubbing his cock. He started to imagine what Lily would look like. He had a pretty good image going in his head when he heard his older sister yell, "Jayjay, come here." He quickly got up and walked down the hall.     He wasn't ready to waltz right in and show off his cock to a stranger, so when he got to Janessa's room, he only stuck his head in. Janessa and Lily were both standing next to the bed, dressed only in their panties. Lily was gorgeous. She was tall and had long brown hair and sparkling brown eyes. Her skin was tan, and she had no tan lines, even around her tits. Her tits were great; they were about a C cup with pink budding nipples. She had long legs and her ass was perfect.     "Hey, Jay. This is Lily. Lily, this is my little brother, Jason." Jason smiled awkwardly. "Come on in Jason. We showed you our boobs, now show us your cock. "     "Ok," Jason said. He nervously walked into the room, his rock hard cock standing proudly at six inches. He walked between them and sat down on the bed.     "Wow, Jay. That's a nice cock you've got there," Lily said.     Jason turned bright red. "Thank you," he said. Lily and Janessa both giggled. Janessa leaned over and whispered something in Lily's ear. She smiled and then they both grabbed Jason's hands and pulled him off the bed. Lily wrapped her arms around him and kissed him on the lips. They explored each others' mouths with their tongues while Janessa kneeled down and explored her brother's ass hole with her tongue. After a few minutes of kissing. Lily knelt down and took Jason's cock in her beautiful mouth. He let out a loud moan. He was getting one of the best blow jobs he ever had, and his sister was eating his ass for him. Jason was in heaven.     Pretty soon he felt that he was going to cum. "I'm cumming!" Jason said, and Lily kept sucking him. He squirted all of his juice in her mouth and she swallowed it all. Then she stood up. Janessa stopped liking his ass and they both pushed him on top of the bed. Lily climbed on top of him and put her pussy right in his face.     "My turn!" she said and Jason started licking her wet pussy. While Jason was eating away, the two girls started making out. They explored each other’s mouths with their tongues, and Jason probed deeper into Lily's pussy with his. Then he pushed a finger in and Lily moaned. He kept adding fingers until she had three inside her. Pretty soon her whole body tensed and she let out a moan. Jason put his mouth right up to her pussy and drank her juices as she came. It tasted very sweet and Jason lapped up as much as he could.     They took a second to relax, and then the girls made their next move. Janessa took Lily's spot and gave her brother a faceful of pussy. While Jason licked her, Lily squatted over his cock. "Are you ready to fuck me, Jayjay?" she asked.     "Yeah," Jason said, and she slowly pushed down. Jason's hard cock pushed straight into her tight, but very wet pussy. She moaned and then started bouncing up and down, riding his cock. Jason continued to eat his sister’s pussy and then he push a finger in. She came almost instantly all over his face. With his sister cumming on his face, and Lily's tight pussy, Jason knew he would cum pretty soon. He started to feel it in his balls and yelled, "I'm cumming!" Lily pulled herself off of his cock but then pushed it deep inside of her ass hole. Her ass was even tighter and Jason came instantly. While he filled her bowels with his cum, Lily rammed her fingers in her pussy and came, squirting girl cum all over Jason's body. At the sight of this and with her brother's licking, Janessa came, too, and Jason swallowed all of her juices.     When they were all done cumming, they laid next to each other on Janessa's bed. Lily and Jason made out while Janessa licked all of Lily's juices of her brother's body. They kept this up for an hour, until the front door opened and Ellie screamed, "I'm home!"
