John and Ruth Smith were considered good parents by their neighbors. The neighbors often allowed their children to play with the Smith s children and even allowed them to have sleep – overs at the Smith s house. The neighbors didn t know that John and Ruth often had sex in the living room with their kids, Billy, age ten, and Jen, age eight, present.

One evening, after they watched John and Ruth fuck on the living room floor, Billy and Jen went to Billy s room and talked.

"They sure looked like they were having fun doing that sex stuff, " Billy observed.

"Yeah, they must, " stated Jen, "they do it almost every night. "

"If they re having that much fun, why shouldn t we?" asked Billy.

"Billy, I asked Mom. She said we re too young to have that kind of fun, " Jen replied.

"Jen, I m not as big as Dad but I get just as hard as him, " Billy boasted.

"Billy, Mom sometimes sucks on Dad s cock when he gets hard. Are you hard now?" she asked.

"Yeah, I am, Jen, " Billy replied.

"Can I see it?" she asked.

Billy dropped his shorts, revealing his hard, four – and – a – half – inch cock. Jen reached out and wrapped her hand around it, shocking him with her boldness.

"What are you doing!" Billy exclaimed.

"I m doing what Mom does before she sucks on Dad s cock, " Jen stated.

Her hand stroking his cock felt so good, Billy moaned. It wasn t long before Jen had his cock in her mouth, sucking and moving her mouth up and down his cock.

"Jen, I gonna shoot, " he warned Jen.

She didn t know what he meant and kept sucking.

"Oh shit!" he yelled as his cum filled Jen s mouth.

Cum came out of her nose and around Billy s cock. She released him and spat his cum into a tissue, then swallowed the remainder in her mouth before blowing her nose.

"Why did you pee in my mouth?" she asked.

"I didn t, Jen. When guys get excited, their cum shoots out of their cock, " he explained.

"So that s what cum is? Does Dad shoot into it into Mom s kitty?" Jen queried.

"I guess so, if he gets excited enough, " Billy replied.

Jen went to her room and lay on her bed. The session with Billy had her excited, and she rubbed her kitty.

Jen riveted her attention on the process when John fucked Ruth the next night. Jen s little kitty started tingling when John s cock entered Ruth s pussy. She grabbed Billy s hand and dragged him to her room, removing her pajama bottoms on the way.

"Put your thing in my kitty like Dad just did to Mom, " she demanded as she pulled Billy s pajama bottoms to the floor, uncovering his hard cock.

Jen laid on the bed with her legs spread, rubbing the top of her slit.

"C mon Billy, stick your thing in me!"

"Are you sure, Jen? I ve heard that the first time hurts a lot for the girl. " he stated.

"Just do it!" she demanded.

Billy did as she wanted. As his cock split her lips, he felt a barrier.

"OW!" Jen yelled.

Billy backed off a little, then thrust in, tearing her hymen. As Jen s eyes became filled with tears, Billy stopped.

As the pain subsided, Jen said, "Get it all the way in me. "

Billy slowly pushed into her. When he bottomed out, he pulled back then drove in again several times.

Jen started feeling the tingles getting more intense and said, "Do it faster, Billy. "

Jen s body stiffened a few minutes later, and her kitty clamped down on Billy s cock.

He continued stroking in and out of her, then yelled, "I m gonna shoot, Jen!" before flooding her with cum.

When he finished cumming, he pulled out and rolled off of Jen. After they calmed down, Jen leaned over and kissed Billy s lips, something she had never done before.

"Thank you, Billy. After the pain at the start, it was great!" she exclaimed.

After that first night, Billy and Jen fucked most afternoons when they got home from school while their parents were still at work.

At the end of the month following their initial fuck session, Jen asked her Mom if she could invite three girls for a weekend sleep – over. Ruth had no problem with it and checked with John. He approved, knowing that they d have to restrict their sex to the bedroom.

On the Friday of the sleep – over, the girls arrived around 7 pm. Billy hadn t seen them yet and wouldn t until later. Sherry and Beth were flat – chested eight – year – olds; Sue was a ten – year – old girl with blossoming tits. Jen welcomed them before they all ran, giggling, to her room.

Around 10 pm, Ruth went to Jen s room and told the girls to keep the noise down; she and John were going to bed. Ruth and John weren t quiet during their lovemaking. The girls heard them clearly since Jen s room was next to theirs. Hearing what was going on in the next room, the girls all stripped and started playing with their kitties at Jen s urging. As they played with themselves, Jen revealed her relationship with Billy.

"You really let him put his thing in your kitty?" asked Beth.

The ten – year – old, Sue, then corrected her, "It s not a thing. It s called a cock, dick, prick, and a few other things. What you call your kitty is commonly called a pussy, cunt, twat, slit, and some other things. When a guy puts his cock in a pussy, it s called fucking. "

Then Sherry asked, "Will he let us see his cock?"

"Maybe tomorrow night, " Jen stated.

The girls all slept naked on a blanket on the floor; Sherry and Beth spooned.

Of course, just as the girls heard John and Ruth s lovemaking, John and Ruth listened to some of the girls moans as they played with their pussies during the night.

Jen woke early and found that Billy was the only other person awake.

"Billy, I told the girls about us. Some of them want to see your cock. I think Mary, the ten – year – old, may let you fuck her, " Jen stated.

"Oh wow! Why did you tell them?" he asked.

"We heard Mom and Dad going at it in their room and we all got excited. We got naked and were rubbing our pussies and it just came out. " Jen stated.

"You were all naked? Did some of the girls rub each other s pussies?" he asked excitedly.

"Beth and Sherry did; they re sisters and I think they do it at home too, " she stated.

"Jen, come get me tonight after Mom and Dad go to bed, " Billy requested.

Jen went back to her bedroom, and Billy went to the kitchen to get a bowl of cereal and stroked his cock as he ate. He came in a paper napkin, then put his bowl in the sink and disposed of the napkin in the trash. He walked around with a hard – on most of the day.

Before they got out of bed, John and Ruth talked about the previous night s events.

"John, I want to hear Billy fucking Jen and maybe one of the other girls, " Ruth stated.

"Yeah, that would be hot!" John exclaimed.

"Why don t I tell Jen that we know about she and Billy and encourage her to take him to her room after we go to bed?" Ruth suggested.

"That s a good idea, honey. You know, I d love to fuck the girl with the developing tits, " he stated.

"Keep that snake in your pants, I want Billy to fuck her, " Ruth chuckled.

John and Ruth got out of bed and dressed for the day. Ruth went to the kitchen and made coffee. John drank a cup when it was ready then took Billy outside to mow the lawn and weed the flower beds.

After an hour s work, John noticed his son s problem and said, "Having all the girls here has you excited, huh. "

"Yeah Dad, they do, especially the girl with the small boobs, " Billy replied.

"Well, maybe you ll get lucky tonight, " John stated.

When the girls came to breakfast, Ruth made them pancakes and poured some juice.

As the girls sat around the table eating, Ruth said, " There s a better way to make you feel good than what you did last night. "

"You heard us, Mom?" asked Jen, worried.

"Yes, Dad and I heard you just like you heard us. What you girls did is normal, exploring your sexuality. Sue, thank you for sharing the common names of the sexual organs with the younger girls. Do you have any sexual experience?" Ruth asked.

"My brother and I fuck a lot, " Sue admitted.

"If you ve started your period, be careful. You don t want to get pregnant, " Ruth warned her.

"Mom put me on birth control already, " Sue replied.

"Good, " Ruth stated.

When the girls finished eating, they put their plates in the sink and ran back to Jen s room. Before Jen left the kitchen, Ruth pulled her aside.

"Sweetie, Dad and I know that you and Billy are having sex. We can smell it when we get home from work. Don t worry, we re not mad, " Ruth stated.

"Mom, it just happened one day after seeing you and Dad in the living room. "

Ruth then said, "Tonight, after Dad and I go to bed, get Billy and take him to your room. You girls can do whatever happens and don t worry about being quiet, we want to hear what goes on. "

"Really Mom? You and Dad want to hear me and Billy and maybe Sue and Billy having sex?" Jen asked, amazed at her Mom s request.

"Sweetie, don t tell anyone, but your Dad and I get our kicks hearing and watching other people having sex, " Ruth admitted, "Now go join your friends. "

Jen went to her room, and Sue asked her what had taken her so long to get there.

"Mom just needed to tell me something, " Jen replied.

Like most preteen girls on a sleep – over, the girls spent the day watching TV, listening to music, dancing, and playing games. John fired up the grill at five o clock, and Jen asked what he was cooking for supper.

"Burgers and chips, " John replied.

By six o clock, everyone was full. They had eaten on paper plates and used plastic cups for drinks, so there was little to clean up other than putting everything in the trash. Everyone then sat in the living room and watched a couple of movies.

The girls changed into their pajamas between the two movies. About halfway through the second movie, unknown to the girls, Ruth started serving berry – flavored wine coolers to lower their inhibitions.

By the time the second movie was over, the girls had each drank two plastic cups of the wine coolers, and John announced, "Bedtime girls. "

When they weren t allowed to watch another movie, the girls complained and asked for one more drink before going to Jen s room. Ruth happily complied, filling each of their plastic cups a final time. John locked the door and turned off the lights before he and Ruth went to their room. Ruth changed into a nightgown before going to Jen s room to say goodnight.

Ruth opened Jen s door and said, "Don t stay up too late girls, " before closing the door.

When Ruth returned to their bedroom, John was already naked. She removed her nightgown and joined him on the bed, and they had noisy sex in anticipation of hearing Billy having sex with the girls. While the girls listened to Jen s parents have sex, they stripped and rubbed their pussies.

After a bit, Jen said, "I m gonna go get Billie, " and left the room.

When she opened Billie s door, he was on the bed stroking his cock.

"Stop that and come with me, " she ordered.

Billie followed her to her room. Jen opened her door, and Billie was amazed to see four naked girls, each rubbing her sex. Jen pushed him into the room and closed the door. Both Beth and Sherry stared at Billie s rock – hard four and a half – inch cock, amazed since they had never seen a cock before.

One of them asked, "Is it always hard like that?"

Before Billy could answer, Sue stated, " It gets that way when he gets excited, " displaying her knowledge.

Jen laid on her bed and said, "Fuck me, Billie, I miss your cock in my pussy. "

Billy climbed on the bed and mounted her. As he pumped in and out of her very wet pussy, Jen yelled, "Harder and faster, Billie. Make me cum. "

In their room, John yelled, "Take me in your throat, Babe, " as Ruth sucked his cock.

Billy did as Jen asked, and a few minutes later, she screamed, " Yes Billie! I m cumming!" as her pussy pulsed around his cock.

When Jen s pussy stopped pulsing, Billy pulled out of her. Ten – year – old Sue was on the floor, legs spread, two fingers in her pussy.

Billie looked at her and asked, "Do you want my cum?"

"Yes Billy, fuck me from behind like my brother does, " Sue stated as she got on her hands and knees.

Billy got behind her, and Sue positioned his cock at the entrance to her love tunnel.

"Push, Billy, " she said.

He did, and his cock sank deep into her. Billy thrust in and out of her, and she met each of his thrusts.

"Oh Billy, you re filling me up, " Sue moaned.

He continued thrusting, and she was getting close to her orgasm when she yelled, "Don t stop, Billy, I m getting close!"

"Me too!" he shouted.

John was eating his wife s pussy in the next room when she came hard, spraying John s face with her juices.

"Ayeeeee cumming, she yelled.

Hearing his mother s scream triggered Billy s orgasm.

"Cumming Sue!" Billy yelled.

As she felt his cock expand with each shot of cum, Sue came with him.

"YES BILLY! FILL ME UP!" she screamed as her pussy convulsed.

Billy remained still as her pussy milked the cum from his balls. When her orgasm faded, Sue collapsed on the floor, ejecting Billy s cock from her pussy.

Sue rolled onto her back and said, "Thank you, Billy, " before she pulled his face to hers and kissed his lips.

Billy laid on his back, satisfied. Jen took his cock in her mouth and cleaned Billy and Sue s combined juices from it. The eight – year – old girls sat there, stunned at what they had just witnessed.

"Billy, will you do that with me?" asked Sherry, one of the eight – year – old twin girls.

"It hurts a lot the first time, " Jen advised her.

"Maybe he should just eat your pussy, " suggested Sue.

"What s that?" asked Sherry.

"It s when a guy licks and sucks on your pussy, " Sue told her.

"I don t know how to do that. I ve never done it before", Billy stated.

"You can both learn at the same time. Sherry, get on the bed with your butt on the edge, " Sue directed.

When Sherry was in position, Sue had Billy get between Sherry s legs.

Sue spread Sherry s pussy lips and said, "See that little bump at the top? That s her clit and it s very sensitive. Use your tongue to lick through her pussy then suck and lick on her clit. "

Billy did as Sue instructed and got immediate results.

"Oh my God, don t stop Billy, " Sherry moaned.

Billy continued sucking and licking until Sherry s body shook with her orgasm.

"BILLY STOP! I CAN T STOP CUMMING!" she screamed.

While Sherry s body shook in orgasm, Billy shoved a finger into her pussy, taking her cherry without her realizing it.

"Eat me too, Billy!" Beth demanded as she prompted her sister to get out of the way.

When Beth was in position, Billy again did as Sue had described. As wound up as she was after watching everyone else having sex, she came the first time Billy licked her clit.

"HOLY SHIT!" she yelled as her body arched.

Billy wasted no time shoving a finger in her pussy as she came, deflowering Beth. His cock was rock hard again, and as soon as Beth s body relaxed, he stood and inserted his cock in her pussy. He moved slowly at first, then increasing the depth and speed of his thrusts.

"Oh yes, Billy!" Beth moaned.

Shortly, her pussy went into spasm, and her body arched as she came a second time.

"OH MY GOD!" she yelled.

Billy continued thrusting, then came.

"Uh, " he grunted with each shot of cum he put in her pussy.

When they came down from their orgasmic highs, they both laid down on the floor. Jen looked at the clock; it was 2 am. She turned off the light and spooned in front of her brother.

In the parent s room, John and Ruth had finished their lovemaking hours ago and had been listening to the goings – on in Jen s room.

"He s like the Energizer Bunny; he just keeps going and going, " remarked John.

"You used to have that kind of stamina too, honey, " Ruth stated.

"Yeah, getting older sucks, " he replied.

Ruth rolled over to turn off the bedside lamp, and they went to sleep.

It was after 9 am before anyone woke up. Ruth was up first and started the coffee, followed by John. They sat at the kitchen table and drank coffee while waiting for the youngsters to get up. An hour later, a naked Billy came staggering out of Jen s room and into his. Ten minutes after that, all the kids were in the kitchen. Each of them looked like they had been up all night.

John made waffles while Ruth cooked a pound of bacon. John put the food on the table, and the kids wolfed it down and asked for more. John made another five waffles which the kids ate and no longer wanted more.

When the girls left the table, Ruth noticed Beth was walking gingerly and called her over.

"First time fuck?" Ruth asked.

"How did you know?" Beth replied.

"Sweetie, John and I heard everything. You re also walking gingerly. Why don t you go take a warm bath, it ll help, " Ruth suggested.

Beth did as Ruth suggested and walked more naturally. When Beth and Sherry s mother arrived to pick them up, they each hugged Billy and kissed his lips before going out to their car.

Sue s Mom didn t pick her up until 2 pm. While they waited, Billy, Jen, and Sue sat in Jen s room talking.

"Jen, you re my best friend and I know this is going to sound strange, but how do you feel about sharing Billy?" Sue asked.

"What are you talking about?" queried Jen.

"Billy fucked me so much better than my brother does, I d like him to fuck me a couple of times a week, " Sue replied.

"Well, now that Billy and I don t have to hide our sex anymore, I don t see why not, " Jen stated.

Grinning, Billy said, "Don t I get any say in this?"

"Shut up Billy, or you won t get any pussy at all, " Jen laughed.

Just then, Sue s Mom, Betty, arrived and knocked on the door. Ruth greeted her and invited her in, then called the kids.

The kids joined Ruth and Betty in the kitchen.

"Sue, were you a good girl while you were here?" Betty asked.

"Yes, Mom. Billy fucked me better than Joe does. I also taught two eight – year – old girls about sex. Billy ate them both out and fucked one of them, " Sue replied.

Ruth turned to Betty and said, "You ve trained her well, but apparently your son needs more guidance if he can t satisfy Sue. "

"I told Sue that she can come here to get fucked twice a week, " Jen stated.

"That s very generous of you to share Billy, Jen, " Betty replied.

"I have a suggestion, Betty. Bring Sue and Joe over to spend next weekend here. Maybe Joe will pick up some pointers from Billy and they ll both have different girls to practice with, " Ruth said.

"What a fantastic idea, Ruth, " Betty agreed.

The following weekend went as planned, with Joe learning some techniques from Billy. Eventually, Billy and Sue became lovers and later, a couple. Joe and Jen were lovers for a while until they each found someone else.

THE END
