Dirty Dice Daydream

My stepsister Jaye engaged in an adult game called 'sensual dice' with her former partner that often led to intense pleasure. The thought of recreating that risqué activity with her now captivates me, and I resolve to take a chance on it myself. Nonetheless, my advances are bluntly dismissed by her.
I am perplexed by her reluctance; she spurns even the most innocent gestures from her stepbrother. Regardless, I find myself indulging in elaborate fantasies where a roll of the dice lands me an opportunity to intimately engage with her, eliciting a provocative response. In this virtual realm, our interactions deviate from conventional sibling boundaries as I submit to distorted desires.
As my fictitious encounter progresses, I sensually explore her whilst her arousal intensifies, leading to illicit exchanges and alluring temptations. Despite being mere fabrications of my mind, these intense moments culminate with intimately arriving at the peak of ecstasy within a forbidden fantasy.
