When she quietly slipped through the door, closing it carefully behind her, she discovered that Kim was indeed in bed, alone, but not asleep. Indeed, ...am could tell that her best friend and sometimes lover was wide awake, although her eyes were closed.Kim had kicked the covers off and lay nude on the bed the two girls often shared. Her knees were bent and splayed to either side, the soles of her feet drawn up and touching. One hand was between her legs, cupping her mound. Through the damp black. In the future, the near future, islanders were going to die because of the water.She had no intention, the thought of helping him out of the water never crossed her mind. The wharf had steps cut in every so often, he made his way to a set and slopped up the steps.

'That's a hull. It took my breath away. I couldn’t help but scream. “After each stroke, you will say ‘Thank you master, that was one, another please’, ‘Thank you master, that was two, another please’’ and so on. If you miss one, you’ll start over. I might stop once you count to ten. Or I might decide to keep doing this until the brand is ready. If you impress me, I’ll be more merciful. So impress me.”I gritted my teeth in preparation for the next blow. It didn’t come. She went back to gently stroking my ass. I just had time to notice this before I withdrew my finger and returned to the previous knee to groin caress. For a while. Soon I again sneaked my finger under her panties. This time I lingered a little longer, a little further and I could make out the shape of her pussy.It felt like a fat roll of flesh and then a cleft. This triggered my curiosity so much that I forgot that I should take it easy and let my hand stay were it was, stroking my sister's pussy under her panties! And she didn't.
