Keep on watching

She knew it was wrong to watch two people getting intimate, but Kayla couldn't tear her eyes away from the scene unfolding in front of her. Jade was the sort of girl who was full of surprises, but Kayla hadn't expected her to make the first move on Jason, let alone so quickly.

As they continued to kiss she compared Jade's sleight figure to Jason's muscular bulk - he should be over powering her, but it was Jade that was taking the lead. She took hold of his hand and placed it on her thigh, before parting her legs as an invitation that she wanted him move it further up. Her head rolled back in ecstasy as his mouth nuzzled against her neck whilst his hand explored inside her skirt.

Jade's hand slowly worked its way down Jason's t-shirt, rubbing his powerful chest and stomach. A look of surprise and delight spread to her face as it made its way down to his shorts. Kayla couldn't make out what Jade then said, but she watched as her boyfriend's sister dropped to the floor in front of Jason and pulled down his shorts. With Jade's back now facing her Kayla's view was obscured, but from the bobbing motion of her head and the grin plastered on Jason's face she had no doubt what was happening.

Kayla couldn't help but feel a little envious of Jade. She and Stuart had taken two months to get intimate, yet Jade had the confidence to seduce a guy and have his dick in her mouth inside twenty minutes of being alone with him. Or was she actually jealous that Jade was with a hot stud like Jason whilst she was stuck with Stuart? What Kayla would give to have Jade's confidence with men.

Meanwhile Jason couldn't believe how well things had developed. The strong, silent act had worked for him plenty of times before, but even he hadn't expected it to have such an effect that Jade would come round, invite herself in and be sucking his cock after such a brief meeting at the pool. He had to give her credit, she knew how to give a blowjob, but knowing that she was Stuart's little sister was making this extra sweet for him . At some appropriate point in the future he would gleefully reveal to Stuart what his little sister was like, but before then there was plenty more fun to be had.

Kayla checked her watch. She knew she'd have to go to work but she wanted to watch how this developed. At that moment Jason said something to Jade, after which he pulled up his shorts and lead her by the hand to his bedroom, where much to Kayla's disappointment the curtains were drawn preventing her observing more. With the distraction gone she quickly gathered up her things and headed for work.
