We were spending July at our summer cottage in the Muskokas.
Dad was commuting from work and during the days there was just Mom, my brother Brad and his friend Jeff and I.
After Dad got home the guys were usually off fishing in the lake and often brought home supper. As Dad left for work early, about 7 am, and didn't get home until after 7 pm we spent the days entertaining ourselves.
My Mom is very open minded and my best friend. At forty-six she is remarkably well preserved and still quite attractive. She tells me how guys often hit on her while she is shopping or just going about her business.
I know Mom has had some discreet affairs by the twinkle in her eyes as she tells me about some of the hunks she knows.
Brad is a sophomore at university taking Phys Ed, which I jokingly refer to as "jogging for marks". My brother prides himself in his athletic body and thinks he is "God's gift to women".
His friend Jeff was a teammate of Brad's on the university football team. Jeff was also very well built and as black as the Ace of Spades.
It was promising to be a hot sunny day and Mom suggested we take a picnic lunch and go across the lake to a great spot covered in lush grass with an opening in the birch forest.
We loaded up the outboard with the cooler, a couple of bottles of wine and a blanket.
The boat droned across Echo Lake on a heading to our picnic spot. It was quiet during the week; we only saw one other boat as we crossed the lake.
Brad navigated the boat into a nook in the craggy shoreline and Jeff jumped ashore with the painter and secured it to a fallen tree bough. We had arrived.
While the boys unloaded the boat I helped Mom, spreading the blanket and filling the glasses with wine. The sun was almost overhead now and the temperature had reached the eighties.
It wasn't long before we had finished the first bottle of wine and were all feeling pretty good.
"I'm going for a swim, who wants to join me?" Brad announced.
None of us had brought swimsuits, we were all wearing shorts, the boys bare chest and Mom and I had on halter-tops.
Brad run towards the water and the last thing we saw was his bare ass as he dropped his shorts and dove into the lake. Jeff was right behind him.
"C'mon in, the water's great!" Brad called to Mom and I.
I looked at Mom and she looked at me a smiled.
"Race ya!" she said peeling off her top and running bare boobed towards the boys.
Not to be out done I followed, stripping on the run. I saw Mom's shorts come off as she dove naked into the water. By the time I hit the water I was naked also.
The water was cool and refreshing. There is something about swimming nude with the water caressing every inch of your body.
I swam over the where Mom and the boys were grouped together. As the water was crystal clear our naked breasts were clearly visible to the guys.
I am no American beauty but do have a lean attractive body. My boobs are only 34B, not pendulous 38D's like Mom's. Mom has gorgeous breasts, large pink nipple about 3" across and teats that stick out after breast-feeding two children. My nipples are just small pink buttons.
Brad had seen me bare ass several times. Being a bit of a tomboy we had gone skinny dipping since we were kid.
Jeff didn't know where to look, at his friend's mother's large breasts of his sister's perky young tits?
The horseplay soon begins.
Brad starts by slashing Mom and I and soon we are all engaged in a wild splash a thon. The tension has been broken.
Bodily contact ensued, first arms brushing against bare breasts and then erect cocks touching my naked body.
