"Yeah, I may have gained a cup size or three since then," she said, smiling. I had definitely noticed her growth in bust size, but it hadn't been so a...parent until now. Her bikini top only covered the very front of her breasts, leaving the sides, top, and even bottom of her E cup breasts exposed. I tried my best not to glance too much."Hey Kyle." I turned and saw another boat owner by the name of Frank standing on the dock. "Is this your girlfriend?"I looked at my mom who was smirking. "Oh, no,. This beautiful woman, wife, and mother, showingme her most intimate anatomy, so explicitly."So, from now on, whenever you hear or say the word'feminine', this is what I want you to think about. This iswhat I want you to aspire to. This is what I want you todream about. You will devote your life to becoming asfeminine as this." Now, I want you to lick me. Lick my vulva. Lick me fullyand completely. Do not touch me with anything but yourtongue and mouth. Don't try to give me pleasure, just. She waved back and upon docking at her place ran to her bedroom to bring herself off. She imagined the pretty little brunette tonguing her ass as she posted on the young buck’s thick cock. A moistened finger and a suction cup dildo on the footboard substituted for the real thing.Nicole made a point of swinging by that dock nearly every day, weather permitting, and the young couple was usually out there. They seemed increasingly happy to see Nicole each time she passed. One day, Nicole worked. "Yeah, mummy! ride that big teen cock! ride that cock!" encouraged my stepsister, as she watched her mother riding me."Feel that big hard shaft inside of you! feel how big it feels you up and stretches your pussy! Don't you just love it?" she then said lustfully as she began to rub her little teen pussy."Yes! oh god yes!" groaned her mother as she began ride my cock a little faster.I couldn't believe this was happening, my own stepmother was riding my cock, she was naked and fucking herself on.
