Alan was at boiling point by the time he waved good bye and reminded Simon and the family they wouldn't be back down next weekend as they had a pool party for the hockey team next week. Alan headed back over to his girls and with the car already packed they were soon on the way back home. On the way he relayed the story of their neighbors. All it resulted in was Kat and Laura getting horny and fingering each other to an orgasm in the back seat. Poor old Alan almost drove right off the road as he viewed his lustful daughter's in the rear view mirror. Both girls were enjoying teasing their father as their dresses rose up exposing their naked cunts to his gaze. "How do we look daddy?" goaded Kat as she pulled her top down exposing her pert little breasts. "Almost good enough to eat honey" he replied. "What about me daddy" Laura chimed in. "You too baby girl" he replied reaching into his shorts freeing his cock so that he could stoke it with one hand whilst driving with the other. Half way home Alan had to pull over at small picnic ground as he was becoming too distracted by his daughters in the back seat. Luckily the area was deserted as the tyres of the car slid to a stop in the gravel of the parking area Alan was already exiting the car. He jumped out and immediately opened the back door to see his girls naked with their dresses hiked up around their chests. "Quick girls out of the car" he demanded almost breathless with excitement. "But daddy people can see us" they both whined. "No there's no one here. We can go over there on the picnic tables. It'll be more comfortable than in the car" he explained as the girls turned to see where he was pointing. They jumped out of the car and sprinted over to the picnic table. Laura arrived first and immediately lay on her back her feet on the edge of the table and legs splayed. She pulled her dress over her head and threw it on the table next to her. Kat soon arrived and she too stripped and immediately had her head between he sister's legs lapping at her bald tight cunt. Alan approached the girls with his zipper open and his hard cock in hand aiming it at his 11 year old daughter's exposed pussy. Glistening with her juices her inner pink folds exposed to his gaze excited him even more. He rubbed the head of his cock on his daughter moist entrance smearing his pre cum along her slit. Up and down he traced his cock head before pushing forward and entering his daughter once more. "AAAAHHHHHHH, OHHHHHHH daddy, OOHHHHHHHH" Kat groaned as Alan reached round his daughter's waist to massage her preteen clit as his cock sawed in and out of her tight cunt. Kat loved the feeling of her father's cock as it grazed along her inner walls. "AAAAAHHHHH,OHHHH, OHHHH, OHHHHH daddy, OHHHH fuck me harder daddy, fuck me harder " Kat demanded as she stood on her toes giving her father more access at the same time using her fingers to open her sister's pussy allowing her tongue to savour more of her sister's love juices. "AAAHHHHHHHOOOOOOHHHHHHHH" Kat moaned as her body flooded her father's cock with her own preteen juices. Alan could feel his cock being coated by the warm bodily fluids of his daughter encouraging him even more to make her cum. Kat's slender hips pushed back hard against her father's invading cock as she shuddered through a series of mini orgasms. Alan kept going as he bent over his daughter's prone body trying to penetrate Kat deeper as his cock plunged in and out. "UUUGGGGHHH, OOHHHHHH, AAAHHHHH" groaned Kat as another orgasm built deep within her body. Her legs started to shake as she held onto her sister to steady herself. "OOHHHH, AAAAAAWWWW, AAAAAHHHHH" Kat cried out as her father's cock slid in and out of her tight fuck cannel. Another orgasm crashed through her immature body wave after wave of sexual tension released over and over. Alan wanting to share his love between his daughters thrust deep and held it hard insider Kat before slowly pulling himself free. "Climb up on your sister and let her clean you up baby while I give her some of daddy's cock" Alan instructed his eldest daughter. Looking flushed in the face Kat turned and looked at her father and nodded as she did as she was told and climbed up into a sixty nine position allowing Laura to feast on her moist cunt full of her and her father's sexual juices. As she made herself comfortable Alan took his slick cock and immediately slid into his 10 year old daughters excite pussy covered in her sister's saliva. Slowly he built momentum as his cock slid and in out of her tight entrance. As he did Kat using her fingers strummed her sister's hard clit. It didn't take long for Laura to start squirming as an orgasm built deep from within her 10 year old body. "AAAAHHHHHH yeah daddy, OOOOOHHHHHH make me cum daddy, make me cum, I want to cum so bad" Laura begged her father. Alan grabbed his daughter forcefully by her slender hips and slammed his cock deep inside her body over and over. Alan was soon pounding hard into his daughter's preteen cunt. Her butt cheeks shook violently with each plunge of her father's long hard cock. Alan was taking long hard strokes withdrawing all the way and then slamming back deep into her hole as hard as he could resulting in a loud slapping sound as their naked flesh met. "AAAAWWWWWWWWW yeah, OHHHHHH daddy it feels sooooo goooooood" Laura panted egging him on to violate her some more. "AAAAAAHHHHHHH harder daddy, fuck that cock of yours in me harder, OHHHHHH yeah harder" "OOHHHHH daddy, OOHHHHH daddy, OOHHH don't stop, OOHHHH I'm cumming dad, yeah OOHHHH yeah, I'm cumming OOOOOOOEEEEEEEAAHHHHHHH" Laura screamed her back arching up causing Kat to vacate her love seat on her body. She sat up and clutched at her father's neck. Alan now had his daughter off the table as he fucked his cock deep inside her body. Laura continued to thrust her hips hard onto her father's cock driving it hard and deep into her preteen cunt hole. She held him deep inside of her as she ground her hips on him. "AAAAHHHHHHHEEEEEEEEOOOHHHHHHHHHHHH" she shouted as the juices leaking out around his cock and over her body. She bucked her hips uncontrollably as she rode through another massive orgasm. Her body shuddered as her cunt gripped her father's cock in a vice like grip. "Oh daddy don't stop I want to feel you shoot in me" "You will honey you will" replied Alan as he started fucking his daughter again in and out in perfect rhythm. "Make me cum again daddy. I want to cum together. Please daddy make me cum" Laura pleaded with her father as her legs wrapped around her father's butt pulling him to her. "Oh honey, I can't hold back much longer" he groaned into her ear. "OOHHH daddy, please wait for me, I'm close to cumming too. OOHHHHH wait for me" she told him Laura was panting hard, she knew that she was building up for a huge climax. Alan kissed his daughter plunging his tongue deep into her mouth. They kissed passionately as they both neared their climax. "AAAAAAAAAHHHHHHHHHHHHHHHHHH, I'm cumming daddy, OOHHHHHH I'm cumming," she screamed. Alan pounded his cock into her preteen body yelling that he was cumming too. He grunted as he pushed his massive cock deep into her young womb. Alan held himself deep inside of her as he sprayed the walls of her womb with his hot incestuous seed. "I feel it daddy, OOOHHH I feel you cumming in me" Laura moaned. The feeling of his cum shooting into her immature womb sent Laura over the edge to another massive orgasm. "OH fuck oh fuck" Laura panted as she collapsed onto her father's chest, his arms instinctively wrapping around her as they hugged. "Oh fuck I needed that daddy" she sighed kissing him deeply on the lips, her tongue slipping into his mouth. As they calmed down they heard "Ahem" coming from behind them. The three of them instinctively grabbed they discarded clothing trying to hide their naked bodies. They turned to see a family standing there opened mouth. The husband looked around 40 years old about 6 foot 2 with light brown hair. He was dressed in a pair of khaki shorts and a polo shirt. His wife was mid-thirties and in good shape with light red hair and freckles. She was dressed in a sun dress with spaghetti straps and a nice set of firm full breasts. The son looked like his father aged about 12 years old. He was 5 foot 9 with an athletic build. He was dressed in a pair of shorts and a tank top. The daughters were twins aged about 9 years old and took after their mother. With bright red hair and a fair complexion with freckles that most red heads inherit. They were dressed in white strapless sun dresses with elastic bodice and a pale blue floral pattern. Their flame red hair pulled back in pony tales with matching pale blue ribbons. "Where the hell did you come from" Alan spat out pulling up his fly as the girls slipped their dresses back on. The four of them silently pointed to the Winnebago in the car park. "Oh god I'm so sorry, we thought we had this place to ourselves" Alan tried to explain. "We saw that" said the father. "You know how it is when your wife feels the urge" Alan lied. "Oh and which one of these children is your wife" he asked. Alan pointed to Kat, "This is Katherine my wife and this is her sister Laura" "God they both look like his daughters Jim" exclaimed the man's wife as she clutched at his arm. "Should we call the police?" "No! No need for the police we were just going" Alan interjected. "Hang on there. Now settle down Louise there's no need for the police. I am sure we can sort this out ourselves" Jim answered trying to calm the situation. "Now let me introduce myself I'm Jim Myers and this here is my lovely wife Louise. Over there are our son Jason and our twin gems Maggie and Mary." "Um pleased to me you" replied Alan holding his hand out to shake their new found acquaintances hand. Alan's only other thought was how the hell do we get out of here. "And you are?" Jim enquired. "Oh sorry I'm Alan" he replied. "And who do we have here?" Jim pressured Alan for the truth. "As I said this is Katherine or Kat as she prefers and her sister Laura." Alan replied holding back the fact they were his daughters. "And?" "And nothing, as I said Kat is my wife" Alan replied sternly. "So you're having sex with your wife and her sister?" Jim pressed on with his interrogation. "Um well we have an open marriage" Alan lied again but in a small way it was the truth. He had in fact had a wedding ceremony and married Kat. The fact it wasn't legal was beside the point. Jim moved closer to Alan taking him by the elbow walked him out of ear shot of the others. "Come on Alan my eyes aren't that bad, Kat's lucky to be 12 years old" he scoffed, "Tell the truth they're your daughters aren't they? Trust me it goes no further than us." Alan looked up at the stranger talking to him resigned to his fate. "Trust me" Jim re-emphasized his point. Alan looked over at his daughters who looked scared at the consequences about to befall them. Alan's head was say just run, but his gut said to trust him. "Look Alan let me put my cards on the table first if that makes you feel better. I would be interested in hearing how you managed to start having sex with your kids. I am dying to taste the sweet nectar of those two honeys over there and I would love to see my son fuck the living shit out his mother. I can just imagine her big titties bouncing as she rides his cock for the first time. My problem is I'm not sure how to get started." Jim confided in Alan. Alan was shocked and relieved at the same time as a smile broke out across his face. "Ok you win. Yes they're my daughters. Kat's 11 and Laura there is 10 years old." He started to tell Jim the short version of how it all started and how they came to be here. By the end of the story both men were sporting huge erections which they were finding hard to hide. Jim asked a few questions about his relationship before and after and how it felt making love to his daughters and kids so young. Alan tried to be as forthright as he could telling him of the physical challenges and the girls determination to have sex, Both men looked back over their shoulders at the anxious group behind them. "Now what" asked Alan? "I'm not sure but we have our RV over there, so why not some over for a cup of coffee and we see what happens" replied Jim. "OK, I'll follow you lead" Alan agreed as they adjusted themselves and turned walking back to their families. "Ok let's all go back to the RV and have a cup of coffee. Alan here has agreed to explain everything." Jim said to his wife and kids. Kat and Laura looked shocked at their father, Alan just nodded and smiled at them to re-assure them everything was OK. They all walked back and settled in as Louise made them coffee and the kids hot chocolate. Louise grabbed her coffee and sat down next to her son on the sofa. Jim had the twins next to him at the dining table, one either side. Kat and Laura sat on the floor at their father's feet looking extremely nervous at what was about to happen.
