Her smooth toned tan skin. Her perfect ass. I worked up past her knees. Her legs and thighs felt so good. My eyes glued to her ass. I was nearly ...here. And then it happened. I suddenly started convulsing. I accidentally blurted out a bunch of gibberish, "Errrggguh... Uuh."I shuttered and trembled. Oh my God, no! I was cumming again! I tried to hide it from Stacy. I glanced down at her and I swear I saw her hide her face by turning the other way. I could briefly see the look on her. I sat down and looked up at her and saw her push her sexy glasses back on her tiny upturned nose and she put one foot on bench right next to me. Too late, I saw the trap of her black silk French undies and her nylons that were attached to them with the sexy garters nurses used to wear back when I was a kid and far too young to get a kick from looking at them. My uniform trousers tented in front and she looked down with a little smile on her face that told me she knew exactly what she was. I guess they were just too big. By the way, my name is Julie and I so embarrassed. Thank you for helping me."The handsome man smiled at her and held out his hand. She shook it in gratitude."It is of no consequence, Senora. I help my Mamacita many times when she break her leg in the ski accident."Julie determined that the young man was from a Spanish speaking country and most disturbingly, considered her of an age in his Mother's range. That bothered her even more that the panty incident. She. The man hissed in his ear, "Let's get that dress up in the back and thosepanties down. I want to feel your smooth sissy bum."He rotated Penny so that now they were front to back and as the sissycooperatively lifted his skirt and tugged down his panties, he felt thatstiff rod, still safely covered, pressing against his butt. There wasthe faint but distinctive sound of a zipper being lowered and then thesensation of an uncovered penis grinding against the center of his ass,fitting itself.
