I walked through the woods as silently as I could. I heard giggling and slowly moved in closer until I could just barely see them off in the distance....Oh my God, they were both naked. My fifteen-year-old sister, Gloria looked just as good as those girls in Dad’s skin magazines. Her girlfriend Rachael looked even better to me. Rachael had my camera and she was taking pictures of my sister as she posed. I only wish that I were the one taking those pictures. My cock was so hard that it hurt.. The boys hung around for another half hour before taking off. I left soon after.It was a good night.Sara came into my room Sunday morning."So where are you going all the time?" she asked"Just out with some friends," I answered."You don't have friends." I thought we agreed if you didn't tell on me then I wouldn't tell on you." I'm not going to tell. I'm just curious. You're different somehow. You used to spend all your time on the computer and I bet I know what you were doing on it. Now you're. I..." I stammered. I was overcome."Now now, no fuss -- remember what you promised your mommy. Come on, pants down," she said as she put the lingerie down, grabbed my belt buckle, and began to undo it. "Let's just get these off."My erection was not the largest ever recorded, but it wasn't invisible, and the proximity of the mother's face to my crotch was not helping matters at all -- a fact my mother quickly discovered."Oh, now I see," she giggled. "A little excited, are we? Well, I suppose. “Have you been to the doctor about it?” “Colin won’t go.” “You sure it is him?” Jack asked her. “His sperm is not like other men’s I have known,” she told him. “Colin’s is very watery and doesn’t taste nice. “Yours is like other men’s I have known, thick and tasty.” Jack kissed her shoulder. “Sorry to hear that.” He told her as she rolled around to face him. For a few moments they just lay here looking at each other. Once again there were things to say but could they be voiced? Suzy.
