    posing naked on the beach. See? Man hungry. So the three of us would watch the skin channel, and sometimes Mark or I would rent a porno video. And the three of us would drink, and get high and get horny. It was great having Michelle there, cuz after a while, she and I would sneak off to my bedroom and get it on, and come out again. I guess poor lonely Mark would jack off in the bathroom, or maybe right there on my couch, for all I know. But who cares, he's a bud. As we did this, over time we had become less reserved about the urges and desires which would arise when we watched the sex flicks. After a time, when Michelle would see my hard-on bulging in my jeans, she would rub it and squeeze it absently, as we sat on the couch and Mark sat on the easy chair. We would kiss, and I would run my hand up and down her crotch without shame or bashfulness. And, depending on what Michelle was wearing, like maybe her trackpants, or even a skirt, she would moan in her sexy little voice as I turned her on more and more. I also saw Mark often with his hand on his stiff cock, bulging in his jeans, as we got all hot and heavy watching people fuck on video. I'm positive Mark had taken to looking at his s****r and his buddy, whenever Michelle and I got so into it that we forgot about the company we were with, and really started undressing each other. I would sometimes openly feel Michelle's tits, and stick my hand down her silky panties and finger her, kissing her and breathing all heavy. And ...
    when we would come out of it enough to announce we were going to my bedroom, Mark would have his hand stuck down his open pants, rubbing his cock through his underwear, and I'm sure it was to the sight of us and not the t.v. which was getting him so horny. It got so that we were so open about it, I would say, "Okay, I'm going to go fuck your s****r now, okay Mate? C'mon, babe." And Mark would say, "sure, go ahead, fuck my s****r," and we'd laugh as Michelle (the SLUT) would protest about us talking about her that way. But we were all high, and we laughed it off. I knew Mark had always had an attraction to his step-s****r, as they grew up together. I mean, he even told me a couple of times how he wished she wasn't his s****r, cuz he really wanted to fuck her bad. But I began to get the idea that Mark was taking steps to that end, when he would say things like, "Man! I could go for a blowjob right now!", and would look over to Michelle. He would say that often. And he began making comments on her body, and how it looked and what was showing through what, quite a bit. But Michelle, having not very much self-esteem, and not a real grip on any Boundaries, just jokingly brushed him off. Maybe after so many years of men paying attention to her just sexually, she felt the need to attract everyone's attention that way, even her own b*****r's. And I didn't care, cuz she was just a girl for now, you know, and I wasn't jealous of anybody looking at her or hitting on her or anything. So ...
