Rebecca's activity

It's already been a week since the first unofficial meeting of the "Nude Club," and you can't hold your excitement at being naked with your friends again. Rebecca got to pick the first activity, bringing you all to the school track field after dark so you won't be seen.

"So, lemme get this straight," Dana says as she strips off her clothes. "Out first activity is streaking?"

"We're not streaking," Rebecca corrects, already nude. "We're only streaking if other people can see us. We're just racing naked. Three laps around the track."

You stand on the starting line beside Chris and Denise. Everyone but Tammy is ready to race. The nerd is timidly taking off her clothes by the bleachers.

"Never thought I'd be using the track for this one day," Chris says to herself.

"Tell me about it," Denise agrees.

Tammy finally catches up to you, wearing only her glasses. "Let's get this over with. I suck at sports."

"Okay," Rebecca says. "Go!"

You start off at a decent lead. Tammy falls behind quickly, no surprise there, and Dana drops out after one lap. Chris keeps a good pace, but soon falls behind. The only thing keeping you going is a focus on Denise's and Rebecca's glorious asses.

On the second lap, you pass Denise for a moment and catch up to Rebecca. She catches your eye and flashes you a cheeky grin, arching her back as she runs and flaunting her jiggling boobs. You can't take your eyes off them and before you know it, you're staring at her ass again. Denise easily passes you. You rush for the finish line, but you still come in third.

Dana claps from the bleachers, gaze resting on your nude body. "Nice show, guys!"

Rebecca throws her arms up in the air. "I win!"

Denise rolls her eyes and walks to the bleachers, panting from the race. Before you can say anything, Rebecca grabs you and drags you underneath the bleachers. She sits you down in front of her, showing off her tits once more.

"Now I'm gonna claim the prize."

She rushes in for a kiss, taking you by surprise and pushing you to the ground. You respond by wrapping your arms around her and shoving your dick into her tight pussy. Rebecca begins to take deep labored breaths and moan into your shoulder.

"I always wanted to do this under the bleachers!" She confesses.

You both fuck like animals until she screams with excitement and ecstasy. Somehow, the scream sends you over the edge and you cum inside her. Rebecca smiles down at you, sweaty from both the run and sex, and gently gets off, helping you to your feet.

You both walk hand-in-hand to the others, ready to go home, but not necessarily get dressed. Chris and Denise are stretching after their run, although Chris seems to be showing off her assets more, while Dana is furiously masturbating, probably from overhearing your tryst. Tammy finally finishes her run, falling down on the finish line and staring up at the sky.

"Can… we not… do that… again?" Tammy wheezes.
