Saturday morning Hannah, Samantha, Tina and Britt drive over to the pond in Samantha’s car. Tina grabs her iPod and some speaker as she gets out of the car, the rest grab the towels and snacks and head to the pond.

The girls strip down to their suits and jump into the pond. They take turns on the old tire swing, swinging out and over the pond. Laughing and giggling they dunk each other in the water. Tina goes to dunk Britt and her hand gets tangled in the strap on her top, causing the strap to break.

“Britt, I am so sorry. Let me see if I can fix it,” Tina says as they climb up on the dock. After a few minutes, they see that it is a lost cause.

“That’s okay,” says Tina, “I’ll just wear my t-shirt.”

“No,” says Britt, “then you will have nothing dry to wear home. Let’s just all go without our tops. It’s just us out here anyway. It’s not like anyone will see us.”

With that, she whips off her top and with a squeal jumps in the water.

Samantha jumped up on the dock and strips off her top and then jumps back into the water.

She swims over to Hannah, “Come on, sis, join the fun,” she says.

She reaches over and unties Hannah’s top letting it fall in the water. Samantha scoops it up and tosses it onto the dock; she dunks Hannah and takes off swimming across the pond. Hannah comes up sputtering and sees Britt, Tina and Samantha all laughing. She give out a shout and laughs as she takes off after her twin.

After a bit of swimming, Hannah hops up on the dock and grabs a bottle of water. She sits on the edge, her feet dangling into the water. Samantha hops up, grabs a bottle, and goes and sits behind Hannah, wrapping her arms around Hannah and pulling her close until her back is against Samantha’s chest.

Hannah is leaning back with her face tilted towards Samantha who is sitting behind her; their lips are locked in a passionate kiss. Samantha is caressing her breast, tugging on her nipple while her other hand is down the bikini bottoms rubbing her clit.

Britt heads over to her little sister, Tina who is lying on her stomach. Tina calls out to Britt as she walks across the dock, “Hey put some lotion on my back so I don’t burn.”

She tosses the bottle of lotion towards Britt, who catches it and walks over and straddles Tina’s back, causing Tina to rear up with squeal. Britt reaches back and swats Tina’s ass.

“Quit moving,” she says, and starts rubbing lotion on Tina’s back.

Samantha is vigorously rubbing Hannah’s clit; sliding a finger into her wet pussy. Hannah moans into Samantha’s mouth as she feels the pleasure mounting. Encouraged Samantha strokes another finger into Hannah; feeling her contracting around her fingers. She curls those fingers and rubs Hannah’s g-spot causing Hannah to buck her hips and to grind against her hand. Hannah leans back with her head tilted, her mouth open in an inaudible cry. Samantha slows as she feels the gush of her sister’s orgasm. Hannah gives her a smile and still panting she leans towards Samantha’s mouth and kisses her.
