Pool time.

You sink yourself down into the outdoor pool. For better or for worse, there's hardly another soul in the water. It's mostly just you and Kimi, and after today and yesterday, you can't help but stare. Her bathing suit clings against her perfect body. The top barely contains her massive, firm breasts, now shimmering with wetness from the pool. She takes off into the water and begins to swim--splashing her long legs behind her.

"Come on, John!" she shouts.

You dive in farther and begins to paddle along with her. She splashes you and giggles, and with a smile you splash her back. She seems to be enjoying herself quite a bit. It distracts you briefly from how attractive she is at least.

After some time of having fun in the water, you rest by sitting on an out-stretching bit of wall within the pool, like an underwater seat. You lean back and enjoy the feeling of the cool water on your body. It's then that Kimi makes her way over and immediately sits down upon her lap.

"Ahh... This has been so much fun. Thank you for everything."

You nod. "No problem."

She begins to wiggle her hips against your trunks, and in turn, your cock. You grit your teeth and start to think of other things. Unsexy things. You try so hard, but all she does is shift around on your lap more and more, giggling quietly as she splashing in the water. Slowly, your erection starts to rise up, pressing against the back of her rear. Thankfully, she doesn't seem to notice at all.

"Can you just... hold me for awhile, John? I get so lonely without my sister. I don't really have someone special either, you know?"

Feeling bad, you wrap your fingers around her soft sides, keeping her practically grinding against you, as soft and unintentional it is. You can't help but enjoy the feeling of her skin, and the warmth of her body against you. How is it this girl doesn't have someone special? You could be that person if you didn't do the stupidest thing ever and tell her you preferred men. You almost want to tell her finally, and end this torment, but both her and her sister might never forgive you. Maybe they'd tell others too.

Your erection begs after awhile longer, but she finally gets up and you breath a sigh of relief.

"All right. Let's go home!"
