It had been a long day of hiking over rough terrain for the four couples.  Finally, they stopped and set up camp. Exhausted, Sue crawled into their cramped pup tent, waiting for Tim.

As the tent flap opened, she rolled on her side to make more room for him.

She was shocked when he pulled down her panties and inserted his hard cock. As tired as she was, she wanted to accommodate him.

He began thrusting into her with uncharacteristic vigor.

"Oh, Tim!"

He stopped for a moment, and then started thrusting even harder, even faster, until she climaxed.

He whispered softly, "Sorry, love, all these tents look the same."

And he was gone.
