Incest is a subject I have only read about rather than experienced so this is a pure flight of fantasy. It is my shameless attempt to write a story for every genre. Please be warned it covers both heterosexual and same sex encounters between Father, Mother, Son & Daughter, so may not be to everyone's preference. Feedback would be appreciated to see if it is worth writing another chapter.
**************************
Jenny sat at the end of Jake's bed bouncing enthusiastically "come on" she cried happily, "tell me all about your Uni." Jake & Jenny were twins, not identical, but similar enough that you could tell they were brother and sister. Both had bright blonde hair but whereas Jake's was cut in the modern floppy style, Jenny's was drawn back into a ponytail. Both shared the same fine bone structure and had inherited the piercing blue eyes from their mother. They were both in prime physical condition with Jenny having the lithe body of a dancer, compared to the more muscular sporting physique of her brother. Jenny was dressed in a loose beach tee shirt with gaping holes under her arms that just about covered her bikini bottoms, while Jake was in a pair of loose swimming shorts as they had been drinking beer & sunbathing all afternoon on their parents deck in the isolated family villa.
The twins had been inseparable from birth and when the time came for them to go to university back in England it came as a huge wrench when they realised the subjects they wanted to take meant they would be at separate ends of the country. Now after their first term away they had flown out to spend Christmas with their parents and other family members in the Canary Islands. Apart from the odd Skype conversations the twins hadn't seen each other since the summer, even celebrating their 18th birthday apart the month before.
"So come on spill the beans," Jenny cooed.
"Well the facilities are great" Jake replied "and the knowledge of the lecturers is immense"
"Don't be a div" Jenny replied punching her brother on the arm feeling heady from the beer and the sun., "I want to know about the sex, how many girls you have fucked, did any take it up the ass, that sort of thing."
Jake laughed, his sister had always been the more open of the two of them, often demanding details of dates and pushing to hear the more sordid details. "No girls" Jake replied, "but if we are asking about sex life, how's yours been?" Jenny wasn't shy as she went into lurid detail explaining that she was fucking her way through the students and had made a good start already. Jake choked with laughter as Jenny described how some random passing stranger had fucked her before she had even found her dorm room. A strange gleam seemed to appear in Jake's eye especially when Jenny used her hands to describe the length & girth of some of the cocks she had enjoyed.
"So no girls at all Jake?" Jenny asked again, "really have you become a monk."
"No" replied Jake, "I think I am gay."
Jenny stared hard at her brother before breaking into peals of laughter, "gay...really ...you are teasing me. So have you been fucked, sucked a cock, or fucked another guy?"
"Yes to all three" Jake replied staring at his sister who fell silent as her jaw dropped open, "that shut you up didn't it."
Jenny began questioning her brother not just about what he had done, but also how he felt and how he felt about girls. "So" said Jenny, "in summary girls don't turn you on any more, you still like sex, and you like having your ass played with. Is that about right?" Jake nodded as she went on, "well I don't believe the first one, I bet I could get you going."
"Don't be silly Jenny, you are my sister" Jake replied feeling a little uncomfortable.
"Sister yes, female also yes," said Jenny rising to her feet and starting to gyrate to a dance beat deep inside her head. "So are my tits nice" said Jenny as she moved her hips lewdly while fondling herself through the thin tee shirt material. The bikini top had been discarded a while before so her pert nipples started to poke though the material. Lifting if over her head Jenny threw the top to the corner of the room and continued to dance in just her brief bikini bottoms that were held at each side by strings tied by a bow. Rubbing herself through the material making a damp patch appear Jenny asked lewdly "am I turning you on brother of mine." It was a pointless question really as Jake's swimming shorts were bulging as the obvious hard on raged beneath. "Best let the dog see the rabbit" Jenny giggled, pulling both strings together causing the bikini bottoms to fall in a tiny puddle of material at her ankles. "Like my cunt?" Jenny asked licking her lips as she parted her other lips with a finger that she slipped inside. Staring into her brother's eyes Jenny moved her young nubile body as she started to finger herself faster causing the squelching sound of her pussy to fill the room.
This final act was too much for Jake to bear and standing he shucked out of his shorts letting his raging erection spring free. Jenny clapped her hands when she saw the size of Jake's cock, "yummy time for a good fucking I think but first I want to taste that wonderful looking cock." Jenny sank to her knees and licked the pearl of precum from the tip before engulfing Jake's cock with her warm wet mouth. Jake groaned with pleasure as he stared down at his sister's blonde head bobbing up and down sending waves of pleasure through him. Finally coming up for air Jenny pushed her brother back onto the bed and climbed on top straddling his hips. "Ahhhhhhhh" Jenny moaned loudly as she impaled herself on Jake's rock hard cock letting the full 8 inches sink deep in. Jenny rode Jake's cock with the energy and enthusiasm of youth, her tight pussy milking Jake as she bounced up and down. Jake couldn't hold back and thrusting up blindly he grunted as he emptied his heavy balls into his sister's tight wet pussy. The feeling of her brother's sperm spurting inside sent Jenny over the top and she thrashed her head side to side as her orgasm ripped through her.
With Jake still inside her Jenny looked down at her brother and said lovingly, "see told you that you weren't gay."
