For an infidel, she was unexpectedly clean and I wasted no expense of time and effort to insure her correct behavior to boost my morale and keep my pr...cious bodily fluids flowing with energy and sublime concentration.In accordance with proscribed procedure, I was the only one other than PC Anderson to know the exact nature, location and time of our target. That was SOP (Standard Operating Procedure) for a mission of this magnitude.I wanted to meet separately with PC Anderson after the cell. It was very hot, and Ben did the grass cutting in his boxers. Lilly came out with two glasses of ice-cold lemonade she made.--- "Wanna lemonade?"--- "Oh, thank you."--- "Ah, it's not for free." --- she smiled --- "Kiss on the cheek, and slap on the ass."--- "Slap on the bum?"--- "That's the price. Take it of leave it." --- she said gesturing to take the glasses away.Ben slapped her ass with an open hand, making her jump up a bit, and spilling a bit of the drink over herself.--- "Sorry." ---. I unhooked her bra after some attempt & pulled her bra out of her muscular balls. With my left hand I was holding her from behind & with my right I was pressing, teasing & walloping her left breast up & down. I started mouth kissing her while appreciating her fulsome breast in my hands.I turned around & lifted her up & I sat down on the edge of the bed & made my sister to sit on my lap. She was feeling the heat of my erected penis inside my trouser on her panty covered ass. I slowly started to. After a short struggle, I got her other hand as well and cuffed them together behind her back. Spinning her around, I pushed her up against the door with one hand, grabbed the middle of her bikini top with the other and ripped it off of her in one quick motion, throwing it over my shoulder. Underneath, were two amazing breasts. This was my first chance to really look at her close up and I was not disappointed. I noticed that she actually had quite a few piercings. A small nose ring, lip ring.
