Maureen had had a bad day at work. Her boss was being a complete arsehole and was blaming her quite unreasonably for things that were going wrong. She was very weepy and came to my office asking if I would drive her home.
We left the office and drove for about 20 minutes where the route home took us through one of London's big parks -- one where Henry VIII used to hunt deer so not right in the centre of the city. It was a nice summer's afternoon and I knew a walk through the woods where there were lots of large trees, flowering shrubs and a series of lakes and streams. I thought the walk through the woods would calm Maureen so that she could have a relaxing evening and face work the next day. As we drove, she was already beginning to calm down and was even starting to smile so things were on the right track.
She was in her normal office attire of a light cream blouse, long black skirt and low heel shoes. It was a summer day so she wore no tights and I knew underneath she'd have on a lacy bra to hold up her impressively sized and shaped boobs and a black thong -- we hadn't been going out long but I knew her well by this stage!
We parked the car a short distance from the woods and walked down the path. It was a popular place so there were a reasonable number of people coming and going. We held hands as we strolled and just chatted normally, enjoying each other's company.
We walked around the lake and with every step, Maureen grew more relaxed and more like her normal self, poking fun at me, laughing and giggling. When she went too far with a comment about something I'd done, I slapped her on the bottom, not hard enough to hurt, just a playful tap really.
"Getting brave aren't you?" she said. "Come on, let's sneak through here and have some fun"
We had to bend down to get through some rhododendron bushes which led into a little clearing where there was a big oak tree. This was well off the path and so although we could hear people as they passed through the woods, we were totally secluded.
We moved together and snogged. Maureen was quite aggressively kissing me and her tongue went straight into my mouth and slid around mine. She was obviously turned on by something, maybe the release of emotion from work, maybe the outdoors and the warmth, who knows. My hands started round her back and roamed from her butt to her shoulders and neck. I put my fingers in her hair and moved her head as our tongues twined.
"Squeeze my tits as well" she said. Normally, I'd need no invitation. Maureen's breasts were magnificent. Large rounded globes with no sag and thick stubby nipples with large dark brown puffy areolae. She wore a bra in the office to avoid some of the more obvious comments and engineers leering over them but she didn't really need one.
Maybe it was the passion of the moment and the pace of our actions but I felt myself taking on an aggressive personality. Instead of obeying her, I spun her round to face the tree and pushed her against it, mashing her boobs against the wide trunk. I pushed my cock into the back of her skirt, trying to find the crease of her arse and bury my stiff erection into it. I knew she liked a little pain so I pulled her shoulder length dark auburn hair back with one hand while I pulled her blouse out of the waistband of her skirt.
"Oh!" She exclaimed as the breath was pushed out of her, "careful, I don't want to get my blouse dirty."
"Keep quiet bitch and take it," I growled, continuing to thrust with my hips. I was turned on too and was assuming a dominant personality to feed both our fantasies. Nevertheless, I pulled the blouse high up above Maureen's breasts so that her bra was rubbing against the rough tree trunk, increasing the friction on her nipples. Maureen grasped the idea of my thoughts and rested her hands on the tree, pushing backwards as much as she could. It wasn't really a serious attempt to escape but accentuated the thrusts I was making from behind.
