The shower stalls are wide open with 4ft high pony walls separating the stalls. I was butt naked facing the back of the stall, when the man came from ...ehind me and offered to soap my back. He started to soap my back nice and slow. He worked his way down to my ass and spent sometime soaping my ass cheeks. He told me how tight they were. I was getting a little nervous, but let him continue. I was also getting excited as to where this was going. I loved the way he soaped the crack of my ass from. It was a ripe dream, soft and full and responsive, and soon her little button under my finger was too sensitive and she pushed my hand away. I pushed her forward onto hands and knees and grabbed her hips forcefully as she pushed back with a happy cry. She groaned as I worked hard against her, my cock burying itself in her belly with every thrust, the age-old wonder of a woman delighting in a man inside her filling my mind.The muscles of her torso were clenching and relaxing as I caressed her.. She grinned and leaned over and gave me a peck on the cheek and said, “That’s alright – I get worked up doing yoga too.” She backed up and stared at my cock that even with this unwanted attention was straining against my shorts and an embarrassing wet spot was forming as some precum was leaking out of my dick. “Wow – you know I’ve never seen you, umm like this… or at all actually.” I was melting under this attention, and could feel my face get hot with embarrassment.She then leaned over. Later Burt told me he,d watched old movie films his Dad also had, but his Dad wouldn’t, let Burt take them out of the house. Those movies gave Burt the idea on how to suck cock and he demonstrated well on me, but even then it was so novel and sent such new sensations I climaxed much more quickly than usual and it was a rather heavy one and to my delight Burt swallowed down every drop and even squeezed out excess cum from my sensitive bollocks! “Did you enjoy that?” he asked as he swallowed down.
