Julia had decided that she wanted to make her rather dull life more exciting. Some of her friends always seemed to be off doing exciting things like skiing, dancing lessons or adventure holidays and she seemed to always be at home working. She wanted to be a more interesting person and also hoped that she might, at last, meet the man of her dreams if she forced herself to go out more. She was not really sure what to do and so looked through the local paper and talked to a few friends and decided to be interesting and adventurous and learn to rock climb.

There was an advertisement for some personal tuition and she decided that this might be better than starting off in a class when she had no idea how good she was or whether it would really suit her. She was quite fit and healthy but had never attempted anything like this before and so was rather nervous when it came time for her tuition to start.

The training was easy at first, all about the equipment and how to use it safely and what to do if there is an emergency of any sort. Julia paid attention but was slightly distracted by her instructor, Brian, who was very good looking. He had a fantastic tan, was muscular, tall and dark and just her sort of man. What she didn't realise was that he was checking her out as well. He loved women with large butts and Julia had a big one. She had no idea that she was that big behind as she had never looked and no one had ever pointed it out to her before but with her safety harness stretched tightly around her legs and bottom he could clearly see what a great ass she had.

They started to prepare for their climb. It would be just a short easy one and Brian suggested that she go first so that she could go at her own speed. Of course the real reason was that he was imagining being able to watch that ass as it got higher and higher above him. She agreed as she knew no different and was soon gradually climbing up the rock, remembering all of the information that he had given her and making sure that all of her hand and foot holds were secure. The feeling was amazing, getting higher and higher and seeing Brian getting smaller and smaller. She was getting rather out of breath and she could really feel her blood pumping through her body and it was a fantastic feeling. Once she reached the top she felt completely exhilarated.

Brian was really enjoying watching her climb up the rock face. He got the most fantastic view of her ass and was sure that it was the best one he had ever seen, and in his job he got to see a lot. It was on the larger side, which he preferred, especially on a woman who was not too fat, like Julia. It was so good he was getting distracted form what he was doing and hardly noticed that she had reached the top. Once he did, he climbed up expertly and quickly. She was smiling broadly when he reached her and he couldn't help but embrace her as he congratulated her on her climb. She tried to describe to him how amazing she felt, but she just did not have the words.

Then it was time to descend and this was a very fast process, just hopping down the rock to the bottom. Once they finished he undid his harness and then undid hers. He crouched behind her as he wrapped them up and found his hands reaching out and stroking her behind. She jumped and turned around quickly and he was forced to explain how attractive he found her and especially her ass. She was flattered and smiled and when he lent in to kiss her she responded. This was not quite what she was expecting but she was happy enough to let it happen.

She did not expect things to move on quite as quickly as they did though. His hands were soon inside her trousers, fondling her ass and they were exploring each others mouths with their tongues as her breasts were pressed hard into his chest. She could feel that her knickers were getting damp and the thought as to where things were going between them made them even more so. Next time his fingers were between her legs she rubbed herself hard on them. The exhilaration of what she had achieved and just the general mood of the day was now making her feel extremely horny.

She began to respond more to his advances, rubbing his cock through his trousers and feeling him all over. She had soon slipped off his top and was stroking those muscles and admiring his six pack. He was busy trying to remove her top, lifting it over her head and then removing her bra. There was a gentle breeze even though the sun was hot and her nipples hardened as they were exposed to it.

His hand was still down her trousers feeling her ass and he was soon pulling them down, exposing her cheeks to the air and she could feel her juices running in excitement. It wasn't long before they were both naked. He had his fingers deep inside her, making sure that her juicy pussy was ready for him. He asked her to lean against a flat rock so that her ass was in the air and he kissed each cheek before nestling his cock between her legs at the entrance to her pussy. He easily slid inside her and was soon moving in and out of her. He was careful not to rush things because a hard thrust could force her head on to the rock and he was enjoying his gentle movements.

She must have been as well as she was soon moaning and was frantically rubbing her clitoris. He increased his pace as much as she dared and she was soon shaking all over and pushing down on his cock. Once she was done, he removed his cock and holding onto an ass cheek with one hand he stroked himself with the other and was soon shooting come all over her ass. He admired what he had done to this fine ass and offered her another rock climbing session, this time for free.
