A truck

It was a large red pickup truck heading their way, it's headlights were already dangerously close to illuminating Rebeca.

"Rebeca run!" Alex shouted having stopped to wait for her.

Without even considering hiding Rebeca took off after Alex and the two continued to run down the street. Even still, they couldn't outrun a truck and soon it's headlights illuminated their bare bodies. The truck's horn sounded as soon as the driver saw the naked women running down the street, and slowed to match their pace.

The passenger window rolled down and an older bearded man said, "Hey there Alex! Where are you and your friend off to?"

"My house, Mr. Davis!" Alex said through her embarrassment. "We lost a bet!"

"Mind if I get a picture before you get home?"

"No!" Rebeca shouted, realizing she was no longer covering her body in an attempt to run faster, and quickly returned an arm to cover her breasts.

"No," Alex laughed as she slowed to a stop, which Rebeca followed. "But I'll show you my tits if you promise not to tell anyone."

"No shit? What about your friend there?"

"You already saw hers when we were running," Alex said which caused Rebeca to turn a darker shade of red.

"I guess I did, alright, deal."

"Whoo!" Alex yelled as she put both hands on her head a did a slow twirl, giving Mr. Davis a complete view of her tits, pussy, and ass.

"Holy shit!" He said. "I thought you just said the tits!"

"I did," Alex said with a sensual smile. "That was for the deal, thanks for not taking a picture like most people would, and another thanks for not telling anyone."

"You are fucking awesome!" he yelled before driving away with another added honk.

By this time they were standing in front of Alex's house. "Why did you tell him we lost a bet?" Rebeca asked now covering her entire front.

"Because it's easier to explain than why we're really naked."

"By the way, who the hell was that and why did you flash him?"

"He's my neighbor and I don't want him telling my parents," she said still not covering herself.

"He's your neighbor and you just flashed him, like it was nothing?!"

"Oh, it was humiliating and he'll tell all of his buddies about it. But he won't tell my parents, it would be a lot worse for me if they found out I ran home naked."

"I guess so," Rebeca said. "Still, I couldn't have done it."

"You might get a chance," Alex said pointing up the street. "Here comes another car!"

"Shit!" Rebeca yelled as she and Alex ran to the house, threw open the gate, and hide in the backyard just as the car drove past the house.

"That was too close," Rebeca said.

"It was kind of exciting though, wasn't it?" Alex asked.

"You think that this is exciting?!"

"Oh hell yeah," Alex said. "Our little strip-show, our streak, and then me flashing Mr. Davis. I'm so wet I'm surprised I'm not dripping."

"Um...how are we going to get in?" Rebeca asked. "Is there a key?"

"Yeah there's a key, the only problem is...
