Rebecca was laid spreadeagled with arms and legs wide, recovering from the latest frenzied lovemaking with her twin brother Jacob, what had been a simple Brother/Sister taunt on their 19th Birthday by her some 4 weeks ago with him, had led to this moment where she was recounting the intense pleasure and multiple orgasms, she had received from him since that time.

He was in the shower as she gently ran her fingers along her aching vagina, feeling the combined Cum juices as they oozed from her, still warm, and mmmm, still thick, then as she put her fingers to her mouth, Oh God, still very salty with a hint of sweetness, Mmmm as the taste and texture covered her tongue ... to die for.

Her thoughts still drifting, stopping at certain moments of time, and conversations she recalled, Jacob used to date one of her friends Sophie, they had split up, because she had felt their relationship had run its course, and the vivid comment she remembered with her ended with her saying “He may have a cock like a horse and be a great lover, but we are not well matched in most other things”.

The part about a horse and a great lover kept circling her mind, she had never really paid him much attention when she lived at home, now in her own place she had found plenty of time for it to dwell more and more and to fantasise on what could be something special.

Rebecca had lost her virginity to a coloured boy in a 10 minute desperate shag against a wall behind the Disco, not long after her 18th birthday, a smile crossed her lips as she brought that event back into focus, Mmmm, she remembered that He had a rather large cock, and even though it had been a quickie, she still remembered the sensations she had felt as it had rammed into her ... and now hear she lay testament that her brother was, better and far bigger ... Oh God she thought I do love him so very much...

She recalled vividly their first sexual encounter, it happened in her hot tub during the summer about a month after their 19th birthday, it had been a really hot day, the water was cool but not cold, he had dropped something from home off and they had lunch which included a couple of glasses of wine, following her suggestion they had retired to the garden and again on her suggestion decided to use the tub, having no trunks Jacob had kept on his shorts which did not conceal his manhood well, much to the delight of Rebecca...

It was a monster and every bit as described by her friend Sophie ... Rebecca decided on entry to the tub to remove her top completely leaving her skimpy panties on retaining at least some of her modesty, In Her usual sisterly brash way. she had said to Jacob ... hope you don’t mind as her breasts swung into view and below the water level ... Jacob could not argue either way, he could not take his gaze off them, she smiled in response to his staring after his startled gasp on first seeing them, she had continued to show brief glimpses of her nipples and areoles to keep him interested ... her plan was beginning to take shape...

She moved to the next step in her scheming mind, which was to taunt Jacob, it started when she asked him his views on her breasts, he was trying to explain when she stood up facing him, she then began to fondle each in turn as she exhibited them to his wide eyes, whilst describing her nice well formed, areoles and stumpy hard nipples circling her fingers around both as she spoke, her tone was sultry, he was transfixed.

Then stopping the fondling she burst out and said, “Hey Brother, why don’t we get buck naked”, “What do ya think”, “com’on brother”, she removed her panties, throwing them off to the side of the tub ... before turning to face him and looking at him in her taunting way a finger to her mouth her head slightly angled she had said with her typical wry smile... “unless of course you are chicken”, “and scared to show your sister what you have in that department” ... her taunting smile and sultry tone throwing the gauntlet his way.
