And then there's that damn thigh-toner machine which, gets them to systematically spread their legs, their cunt-lips pressing out from underneath span...dex towards us men. Go ahead; call me weak-willed.One day at the gym, one such gorgeous young lady had been thrusting out her perfect, toned, sizeable, shapely ass, with her back arched like a tigress in heat, towards me all afternoon, giving me sidelong 'come hither' glances. Next thing I knew, I was on some machine when I saw her directly across. I ... I wanted my sister more than anything else in the world. I wanted, I wanted to kiss my sister. On the lips. Letting her know I meant it.But then she took my hand. Mandy tugged me into the livingroom, big and bright from all the windows. She stopped us in the middle of the room and then slowly and softly but brightly she stripped us of our clothes.My jaw dropped, seeing her breasts for the first time. They were just big enough to sway every time she took a breath, topped with taut cherry. I then picked up her other foot and did the same thing. Just as I was starting to get into it, our buzzkill parents came out of the water and started running towards us. Fuck! That’s twice today!“You guys have to get in the water, its so refreshing!” said mom. “Yeah, it really takes the edge off” dad added. If there was anything I needed at that moment, it would be an edge being taken off. I folded my cock into the elastic part of my pants so it wouldn’t be noticeable. I grabbed my sister by. She inhaled as if she smelled the most wonderful fragrance. I was holding the bottle at arm's length and it was all I could do stand the smell.When Walter came into the room, we got started. "Tricia," I said. "Tell us the name of your lover." Stan," she answered, her eyes still fixed on the now blank TV."How long has Stan been your lover?" A month." The bitch. I'll kill her," Walter said very quietly, making me nervous."Hey Walter. I've always wanted to see your wife naked. Think this is a good.
