"Enjoy your journey, miss." The conductor said with a smile as he handed the now stamped ticket back to Victoria.Victoria looked down at her chest, he...r nipples were erect and visible through her tight woollen jumper, was that what the conductor was smiling at? The thought alone only added to her now aroused state.The carriage was warm, and Victoria now slightly flushed, elected to remove the jumper, revealing a short sleeve fitted blouse that hugged her figure. Her erect nipples were now even. “Whoa hun , why you in such hurry?” Frank said confused. Sarah didn’t say a word as she turned shaking her lovely tits at Frank. She laid down on her side facing him. “ Well baby do you want help with your “problem” or what?” Sarah asked with lust in her eyes staring down at Franks erect cock. Sarah lifted her head up to Frank’s lips and gave him a deep kiss. She pushed her tongue into his mouth and explored. She gently bit his lip and played with his tongue. Soft moans escaped her. I wondered what the night had in store? Nicky was never boring and was always game for a laugh.When I got back Nicky was on her second glass of Vodka, she said telly was boring and did I fancy playing spin the bottle? The rules where quite simple, you spun a bottle and when it stopped, whoever it was facing took off an item of clothing.We tossed a coin for who went first, I won, I spun the bottle and lost, so Nicky had me take off my T shirt, because the loser won the spin I spun again, but I. It made me wonder why sex between siblings was so taboo, even illegal. Most would say it’s because there’s the chance of having a disabled child or something but that wouldn’t be an issue for me, for us I mean. When I was 17 I lost the ability to conceive, I had contracted a virus through a blood transfusion after a car accident, I had been in a friends car and she had been going to fast and I think she was slightly drunk, it was after the accident that we, my brother and I, had become closer.
