M(30) at the time of the event. I was working as an engineer for an infrastructure project at the time and we had to do some bat mitigation. In order to do that the company employed the services of ecologists that needed to do bat surveyes of the trees that needed to be felled. Needless to say that these surveys take place during the night for obvious reasons and I was supposed to supervise the ecologist group while on the construction site (4 females and 1 male, all aged early 30's or late 20's). This site was about 3km long and the trees were scattered all along the route in a strip of quite thick foliage.

One of the girls (lets call her Sara) was flirty from the start and felt like something might be there. She was even acting a bit slutty and often would make sex allusions during the conversation.

I was supposed to go check on these guys (there were all working separate) throughout the night so I was making 'rounds' every now and then. When I knew I'd be reaching Sara I decided to scare her a bit so I started making noises as I was approaching her. She tried to called my bluff but as I didn't stop she soon got scared and straight away called my work number (which they had in case of emergency and were to suppose to check in by text every 30 minutes).

When I came out from the foliage laughing she called me an asshole but burried herself in my chest, hugging me, saying that she was really afraid and that I shouldn't do that to her (she was using that tone that women use when they want something from you). It wasn't long before Sara and I were making out and she was moaning in my mouth, trying to feel my cock through my trousers (which was hard). Very soon after her top was off and I pulled her tits out of her lacey black bra (she had impressive tits) and I started sucking on them and biting the nipples as she moaned.

Sara dropped to her knees and started sucking me off. She was quite skilled and knew her way around, making sure nothing is ignored. I helped her a bit by holding her head and thrusting my hips.

It wasn't long before I came in her mouth and she swallowed everything. She even said it was delicious which I know was a lie due to my diet at the time.

We've met several times afterwards in various circumstances (including a few hotels) before she had to move away with work.
