As I laid there with my eyes half closed I heard some movement in the yard. At first I didn't see anyone, but then realized it was Alex's father. It l...oked like he was lurking in the yard. Did he see me? Was he spying on me? Should I cover up or pretend not to see him? Damn, what should I do?I had a split second to make a decision. I normally would have covered up but being topless in the warm sun I was feeling a bit risqué. I liked Alex’s father and I knew he liked to watch me, so why not. I’d never been sucked off either so I was all for it. In porn we’d seen pictures and read about guys and girls doing oral so she knew the basics. She’d also hand jobbed me lots of times before so she knew how to take a guy to a cum.I stood by the side of the bed with my legs spread. From romping with Alison my cock was well erect, and in anticipation of what I was about to get I was up rock hard with my cock sticking out bending up in front of me.Alison got onto the bed in front of me on all. Black Cat was made to spread her legswide open. Nelson tied her ankles to the upper bedposts of the bed. This madeher look as if she was offering her ?cunt? wide open.Nelson also had her blind folded, and her mouth had a ball gag on it. ?Now for some fun?, said Nelson. He took his dad?s shaverand shaved off her nice brown pubic hair, till it was completely skin. It looked like an open crack. Nelson said, ?Excellent,an open Mexican crack?. He laughed at his own joke. Nelson was going to play. His eyes darted around her on the rock, up one shore, the other, and then he found it!She wears clothing! Modesty must be of some value to her. But there is a blade in that little pile, I must be careful. He concluded to himself.Without a second thought he swept down to the bank where her neat pile of clothes and a heavy cotton bag had been tucked, took the whole bundle in his arms and flew to the centre of the pool at the bottom of the waterfall.“Oi! That's mine!” the red haired creature.
