I have had sex in tents quite a few times from various camping trips and different girlfriends that I have had and been on. Only 2 of those occasions really stand out for me as being really memorable. This is what happened on one of those occasions to make it really unique.
My sister and I have always been very close. We were both in relationships with our partners from the mid 80's to now. By the late 1990's we were both single again and in no hurry to get reattached at this stage.
By 2002 we had both been split up from our partners for a few years and the
Christmas holidays were approaching so my big sister, who is 3 years older than me, and I decided to get away for a few days together. I was in my mid 30s at that stage. We both enjoyed sightseeing type road trips and so we decided to head to Golden Bay and Kiateriteri together for a few days over New Years to do some exploring.
So when the time came a week after Christmas day we headed off to Nelson city, about 450km north of where I live. We decided to stay at a holiday park in a small village called Mapua, and spend a few nights there over New Years eve (Our mid summertime) 2002. Mapua was a clothes optional camping ground, some nudist were there mixing with the general campers by the swimming beach area but that's not why we were there. A lot of families camped there and were always clothed along with about 80% of the people there (at this time of year anyway).
It usually only seemed to be singles and some couples that got around nude. We made ourselves out to be a couple. We always had clothes on, not many because it was so hot. It was just an amazingly vibrant and nice place to be during our summer holidays.
The day we got there was the last day of 2002 and was very hot and humid. So we set up our tent, a small 3 person mountaineering tunnel tent with a double size foam rubber mattress on the floor in a nice big grassy meadow with a few large trees around to provide some shade from the intense afternoon sun. Camping next to your car has the benefit of bringing a few extra home comforts to make it a more comfortable experience. The closest other tents were about 60 to 80 meters or more away and you just picked a spot where you wanted to go.
Heaps of room but also heaps of people, self contained units and caravans were packed more closely together because they were all on powered sites. There would have been at least 500 or more campers here, a lot of families with larger tents and caravans, couples with smaller tents like ours scattered a bit further out from the facilities. The place was full of life and happy people.
Mapua sits on quite a nice tidal waterfront so we went down there where people were swimming by the beach mid tide, some nude most not, and had a couple of drinks at the bar. It was a lovely sunny day, a really nice setup back then.
By about 2pm some ominous looking clouds started to come over and you could hear some distant thunder rumbling slowly creeping closer. We finished our drink and walked back to our tent, it started to cool off and get a bit windy. By the time we got to the tent it had just started lightly raining. We went inside, dressed just in shorts and a tee-shirt and sandals, lay down on the bed steering at the roof and listened to wind, rain and thunder getting louder by the minute. Our little tent held the heat in really well and was still at least 10 deg C warmer in there than outside. After a few more minutes it started raining a lot harder and the thunder became much louder, it got quite a lot darker and you could see the occasional flash of lightening followed by very loud thunder through the thin yellow nylon tent fly.
We thought we could be in here for a while so we took the opportunity, I think we read each other's mind, without saying anything we both stripped off completely nude and got into a 69 with me on top, sucking on my sisters clit and licking between her labia with my tongue while she started sucking my cock and tickling my balls. Her pussy was recently short shaven and not hairy. Very nice to look at.
Her vaginal juices really started flowing and tasted so sweet, my mouth was getting quite wet around the outside. After a few more minutes it started hailing lightly then suddenly got heavier and heavier until the noise was so loud you couldn't hear yourself think.
