It was an ideal holiday spot for my husband Rick.
We had set our twenty-seven foot trailer up on a site in a camping ground on the shore of Georgian Bay, a fisherman's paradise.
Rick had taken the aluminum boat off the top of the car and spent most of the day out fishing with Bob, my brother.
Bob and his wife Carol had eagerly accepted our invitation to join us for a week's vacation.
Carol is a couple of years younger than me, a buxomly blond who had always captured my husband's eye.
Bob and I had a normal brother and sister relationship as we were growing up and had played "doctor" one time when I was just passing through puberty.
The campground held a colony of fishermen, it was the peak of the season and ardent fishermen had come from all over to fish the productive waters of Northern Ontario.
Trailer living was quite cramped, sharing such a small space with another couple required a relaxation in customary decorum. Carol and I were soon wandering about inside the trailer wearing just pajamas or panties and bra while the guys prepared for their day on the water.
Even though Carol had large breasts she wore the lift and show type bras. Little more than half-cups with her nipples almost spilling out of the top. Her panties were equally as brief, high-cut bikinis with some transparent enough to clearly see the outline of her camel toe beneath. None of his wife's exhibitionism bothered Bob and Rick's eyes could not get enough of it.
Nobody seemed uptight by the excessive familiarity so we soon all became comfortable in our new cramped living quarters.
The shower in the trailer's washroom was very small so Rick had set up a shower outside of the trailer. It was just a canvas enclosed stall with a hose to the showerhead. There was no hot water but the water from the tap was not very cold and the weather was quite warm.
Everyone liked to use the shower during the day when it was warm and the sun's rays would help dry them off.
I was cooking some chicken on the barbeque which was about twenty feet away from the shower stall and in direct view.
As I was preparing the meal Bob came out with a towel wrapped around his hips to use the shower.
My eyes inadvertently went to the shower after he had entered and observed he had not closed the curtain tightly and I could see him standing naked under the stream of water.
He was washing himself with a cake of soap and I saw his cock was fully erect. It was a beautiful cock, seven or eight inches with a fat shaft and a smooth mushroom helmet. I got a sudden urge to take it into my mouth and to suck his sperm out through it.
Bob finished showering and neither of us indicated that he had displayed his lovely cock to me but we both knew it had brought us closer to consummating our desires.
I couldn't get my brother's cock out of my head, no pun intended. The thought of what it would feel like in me fascinated me. Rick was o.k. but his cock was not as powerful as my brother's looked, I imagined myself moaning with Bob's cock deep inside of me.
Since Carol was constantly around when Bob was there was little opportunity for me to seduce my brother. I knew Rick was open-minded enough to agree to a least a threesome with me and my brother but Carol was pretty straight.
That night I lay in bed listening to my brother fucking his wife. Separated by the thin walls it was almost like we were in the same room.
Carol groaned as Bob drove her into the mattress at an ever increasing pace until she cried out in her orgasm.
I held my husband's semi-erect cock in my hand as he slept oblivious to the passion around him.
"Sounded like you had a good time last night?" I asked Carol after the guys had left to drown some more worms.
Carol blushed ands smiled a demure smile.
"Rick would really like some of that." I teased, "He was listening last night and thinks you are really hot!"
"Really?" Carol responded mildly interested.
"He'd be on you in a flash." I assured her.
"I'd kill Bob of he touched another woman." Carol decreed.
"Even if you were with him" I teased.
"What do you mean?"
"If Bob was fucking someone else while another guy was fucking you." I explained.
"Bob would never agree to someone else fucking me." Carol smugly replied.
"Don't be too sure!" I said and went on to change the subject.
We had finished supper, they guys had brought back their limit in pan fish and we had a fish-fry outside the trailer.
Bob and Carol had gone for a walk to explore the campground and I was talking to Rick as he helped me cleaning up.
"I think Carol would like to fuck you." I shocked him.
Rick looked at me surprised, "What do you mean?"
"We were talking this morning and she said she would let you fuck her." I embellished our earlier conversation.
"Bob would never go for it." my husband resolved himself.
"Let me talk to him." I smiled.
Rick and Carol were sitting by the campfire drinking Budweiser and reminiscing of the time we had gone to Florida together. Bob had come into the trailer with me to get some snacks.
