Beach-Front Property

We were on a deserted beach, just Dad and I.  Mom and the other kids had gone shopping and we were lying on blankets, under the umbrella of course because we're all sun-conscious.  No one around.  We were in a secluded part of the beach.

"I feel frisky," said Dad.  His cock was standing at attention.  "Your mother wouldn't necessarily approve..."

I had his shorts down faster than he could finish the sentence and a short time later had my bikini pulled to the side and his cock thrusting up into me.  We took it slow, just enjoying the thrill.  At first.  Then it got hotter and heavier, towel thrown over us to hide as I straddled him, bikini off completely so he could get his lips on my tender nipples.

"Mind if I watch?"

We both stopped dead and peered around the umbrella to see a middle-aged guy standing there, tumescence already showing in his shorts.

It took us a moment to regain our composure.  "Why not?" Dad said.  "Make yourself comfortable."

"Don't worry, I'm not a freak or anything," the man said.  "I have a house over there and was admiring the two of you, so I decided to stop being a perv and come introduce myself."

"Can I do anything for you?" I asked.  I was raised to be polite.

He came closer and pulled down his shorts without saying a word.  Pretty soon I was sucking a stranger's cock while my Dad plowed me from behind until he grunted, "Hope you don't mind sloppy seconds," and unloaded into me.

The stranger took Dad's place without question.  He wasn't much to write home about but the novelty and excitement got me off before he asked, "Is it okay if I cum inside her?"

"She can make her own decisions," laughed Dad.  He was stroking himself idly, coming back to life.

"Can I, young lady?"

"Please."

He came buckets.  He must have been hard up or had been working on his load for ages.  "If you're ever in the neighborhood, come by," he said while I cleaned him off.  Then he pulled up his shorts and strolled off, leaving Dad to pull me down to him and begin again.

And that was the last we saw of him.  Maybe he was a ghost.  I don't care; it was fun.
