First a nice long shower then wearing only a towel I settle onto the couch to watch some porn I have borrowed from my dad's stash, what else would you...expect a sixteen year old boy to do? The movie is getting going and I open the towel to release my now raging hard on. The movie is really getting going and so am I, so much so that I hadn't noticed that my sister Susan and her friend Kate had returned home unexpectedly until they were in the room. "Alan!" she shrieks, jolted back to reality I. She has very large natural breasts that were pushed up and out by her new black lacy bra and she wore a short, tasseled skirt with no panties. Her pussy is kept shaved and by this point in the evening she had flashed it to both men at the table. Both of the other women were bi, so at this point all four were becoming very interested in my wife. Carolyn was still in the kitchen when Sela and the others moved outside for a smoke. Sela doesn't usually drink so she was buzzing from the wine and the. Behind her she could hear Daddy Bear explaining things to Junior Bear as he lifted her skirt. "Now son, this hole is her anus, we may come to that later, but for now just know that it is not for mating in order to make babies. The important part is this hole, which is called the vagina. Before we can do anything, we must make sure that it is wet and slippery. Climb on to the bed, that's right, and touch it with your finger. Now is it wet?" It's kind of slimy." Then she is already excited, but. Her red bush showed through the yellow fabric and looked almost orange with the play of the lemon yellow panty fabric. “WOW,” I said, “How did I not know how sheer that panty was?”“I love that it still fits, this panty has got to be almost 10 years old,” she said as she modeled it in her bureau mirror. “Look how well it fits my ass,” she said as she turned and looked over her shoulder. “I love it.” She said with a smile and then she walked over to me and hugged me. My cock twitched, the horny.
