Not strictly speak an Incest tale, this is a story of taboo sex within a family circle.
It's a slow burn so if you want Wham Bam Thank You Mum in the first 100 words, this isn't for you.

"Hey Kirsty, how are you!" Tom said as he bumped into his brother's girlfriend at the bar.
"Oh, hi Tom! I didn't expect to see you here." she replied, pleased to see him.
"No, it's a friend of a friend thing and I said I'd come along for a drink and a laugh." She caught the barman's eye and ordered some drinks including one for Tom.
"Is Jessica not with you?" Kirsty asked.
"No, she's working late on something or other. Rob, not here?" said Tom, asking about his brother.
She pulled a face. "No, something to do with promising someone he'd help them do something blah, blah. I thought 'Stuff it!' I'll get a few drinks inside me and let my hair down."
He nodded to her tube top. "Mind you don't let something else down, your girls look ready to jump out of that top."
She laughed. "Yeah, that'd get me noticed by the guys. Tom thought 'She doesn't need that to happen to be noticed. She looks amazing. And her tits – huge – and so much on show.'. They chatted over the music. As they did, Tom thought about Kirsty. He had always found her very attractive and sexy. Of course, she was with his brother and he had Jess so he never thought about her any further than that but there were fantasies.
Kirsty liked Tom. He had something about him, more than looks and personality. He passed the 'Would I?' test with a very big 'Yes!' except for the fact that he was her boyfriend's brother. They both went back to their respective groups and the event proceeded.
Later, when the disco dancing was underway, Kirsty fancied a dance but there was no-one in her group to dance with except other girls which she always thought was a bit naff. She saw Tom across the room just chatting and drinking. She went up to him and said "Hey Tom, fancy dancing with your brother's girlfriend?" He got some mocking noises from his friends but he got up to dance with the busty blonde, leaving them quite jealous.
A Roxy Music track, 'Avalon', blared and they danced near the edge of the dance floor. Tom was mesmerised by Kirsty's very sensual horny moves to the music and particularly the swaying of her impressive breasts, all to the sexy beat of the song. His friends were noticing her too. As the song began its long play out, he stared at the suggestive movement of her hips as she pushed them up and down to the sensual beat of the music.
Tom imagined her making those moves whilst impaled on his stiff cock. His chain of thoughts progressed to wondering what her pussy looked like, was she tight or big like Jessica is. He imagining how it would feel if she was tight, and was she shaved, did she like it being licked. Conversation wasn't possible but he enjoyed this dance and especially his view of 'the girls' and his secret naughty thoughts.
The DJ slowed the mood right down with a smooch number and Tom made to leave the dance floor but Kirsty grabbed his arm. "No, Tom, stay and dance to this one - please!" She pulled him to her by his arm. They held one another and moved to the music. Though it was slower music, Kirsty was no less sensual and the lyrics added to Tom's very sensual experience.
Her moves were so horny for a young man to watch or be a partner to. She pushed her hips close to him, pressing herself against him quite raunchily. They could talk now, although Tom was also distracted by the close up view of her cleavage or 'the girls' as he had referred to them. They looked incredible, not that he was short of contact with big tits in his life but any new experience is always exciting.
"So, Jessica's working – it's a shame she couldn't be here." said Kirsty, not meaning a word of it. She moved her hands to Tom's neck, whilst his were on her hips.
"Yeah and she won't be home till very late either because of the journey. You seeing Rob later?"
She shook her head as well as grinding herself against him. "Nah! I decided to get a room here. Cheaper than a taxi. Go home in the morning."
Tom was wrestling with his conscience. His desires were telling him to make a pass at Kirsty, but she was Rob's girl and he had Jess. But Kirsty was so hot, especially tonight – and his instincts told him that a pass would be well received by Kirsty. He felt her push onto him again. He was getting aroused by it all. 'Anyone would!' he told himself.
Kirsty pressed her breasts against his chest. She liked the feel of it. She sensed her nipples crumple and harden with her arousal. 'I can't get naughty with Tom, can I!' she told herself but she didn't convince herself. Another slow track was played. Kirsty gradually manoeuvred them into the middle of the dance floor. She pushed harder against Tom and by now he had a full erection, albeit it was trapped by his pants pointing uncomfortably downwards.
He gazed at her lovely tits and wanted to caress them. Her perfume added to his excitement too. It was new to him and it was lovely. She pushed her hips again and realised what was happening in his trousers, his cock having formed a hard lump which she ground on. 'Oooh, Tom is excited by me!' she told herself.
She let her head rest on his shoulder, looking at him, not away. He gradually turned his head and lowered it and, almost with reluctance, perhaps due to their circumstances, their lips met. A touch, another touch then a proper connection, a proper kiss. Her tongue was first to visit the other. The kiss became sensual but not animated. They did not want to draw attention to themselves. Their tongues darted and teased. The kiss was extended and extended again. Her body pushed onto his hard lump. She felt herself getting moist as a result of it all. Her tiny panties were becoming damp.
