A change of venue.

"Let's go swimming!" Beth suggests.

Becky perks up from the bed. "Where do you suppose we do that?"

"The Solomon's pool is always clean and they never use it! Aaand, I heard Mrs. Solomon tell mom that she and Mr. Solomon are heading up to their cottage for the whole week!"

"I don't know, we shouldn't be trespassing on other people's property like that..." Becky replies, "besides, we're supposed to be waiting for mom to call from Florida."

"Oh please, they won't know and we'll be back before mom calls, she always calls just before midnight." Beth responds. It doesn't take much to finally convince her sister, just a shake and smack of the tush and the two are running downstairs.

"Hey wait," Becky cries out, "Aren't you going to put something on?!"

Beth rolls her eyes in a "Let's not go through THAT again," look. She then approaches the back sliding door, peeking both ways to make sure the coast is clear.

"You're joking, right?" Becky asks in disbelief. In response, the younger girl slides the door open and hops outside. Becky rushes to the exit but stops short of the back yard. Her head peaks out to see Beth's naked body skip across the yard and climb over the fence. Hesitantly, the older sister follows. Hearing a sploosh as she climbs the wooden structure between the Stillman and Solomon households, Becky peeks over to see her sister already doing a lap in the pool. The water glistens off her smooth naked backside. Beth switches to a backstroke so that her sister can enjoy the view of her cute breasts and pussy. Becky joins in shortly and the two engage in splashing each other before Becky dives under and captures Beth between the legs. The younger brunette sits up on the pool edge so her elder can surface to breathe.

Becky laps away at her sister's cunt as the cool water brushes against her skin. Meanwhile, Beth basks in the warm glow of the sun and the wetness of her sister's mouth. "Hoo oh oh!" she cums again in a small orgasm and pulls Becky up to kiss her thank you. The two embrace and makeout for a while until Beth guides her older sister to a nearby lawn chair. Seating her there, Beth reciprocates Becky's earlier muff diving with some of her own. "What if someone sees us out here, Beth? Ho ho Ungh... ungh! Oh my god, that would be so embarassing... but huh huh... hot... ungh..." The excitement of being caught forces Becky to cum quickly.

The girls lay together once again, exchange small pecks and slowly rubbing each other's wet bodies. Suddenly, Becky's ears perk up. "Is that music I hear? Inside the house?" She immediately becomes alarmed and her voice is almost a whisper, "I thought you said no one was home!"

"I heard mom and Mrs. Solomon talking. I know for sure they were talking about this week..." Beth reasons.

"They could have changed their plans..." Becky replies, looking around frantically.

Beth gets up and walks towards the house. She peeks in through the kitchen window. "There's no one downstairs... and their car isn't in the driveway... Maybe someone left the radio on."

"Well, we should get back in any case," Becky responds.

"Uh huh..." Beth answers. She slides the apparently unlocked back door open.

"Beth! What are you doing?!"

"I'm just going to peek and see..." she responds.

"Well, see for yourself! I'm going back!" Becky is true to her words and she hops over the fence. Beth, ignoring her continues on inside.
