Kathy came up for air and cried, "It feels terrific!" She quickly shook her head, then dove back into the water. Her eyes open, she saw myriad small fish swimming all around, darting to and fro.
Suddenly Tommy grabbed her waist from behind, locking both arms around her, pressing his dick against the cleft of her ass. She spun around and they embraced underwater. They came up for air and kissed.
"This is the best day of my life," Kathy said.
Tommy chuckled. "Mine too."
Bobbing up and down in the water, they watched Edna swim in graceful circles around them.
They all swain for a long time, until their lips were blue and their teeth chattered like castanets. Then they lay sunbathing on the rock.
"Better not stay out too long," Edna warned Kathy. "Your skin isn't used to all this sun yet."
"I know," she said. "I'll be careful. Give my front a little bit, then turn over on my back for a while."
They lay peacefully together, content to do just that, sharing one another's silent company while soaking up the sun. It was a clear, still afternoon. The sky was cloudless and a bright blue.
Tommy fell asleep. Kathy idly thought of making love to Edna, but she couldn't be bothered to change positions. There would be plenty of time to continue her lovemaking with both Edna and Tommy, and with the two of them together. For the moment, however, she just lay still, at peace with herself and the world.
The rest of the afternoon passed languidly and easily. Edna dozed off herself. Tommy snored slightly, lying on his back, his cock lying like a snake across one thigh, his balls hidden between his legs.
Kathy decided to masturbate, while gazing on her two naked lovers. She lay on her side, watching Tommy's chest slowly rise and fall as he slept. Her eyes traveled down the length of his body, to his manly sex. Then over to Edna's tits and dark, hairy crotch.
Her fingers dug deep into her slit, caressing her clit. Her back arched and she bit her lower lip to keep from crying aloud. Pleasure coursed through her body with warm pulsations.
She climaxed twice, then slumped back down, her ass wriggling into the rock. She sat up, then stood and stretched. The blood rushed to her head, making her momentarily giddy. Her body glistened with sweat. She needed to cool off.
She slipped quietly into the water and swam in lazy circles while Edna and Tommy continued to sleep.
She looked at her waterproof watch and saw it was getting late. Dinner would be ready soon. She should be home giving her mother a hand. She swain for a few more minutes, then climbed onto the rock and gently shook Edna and Tommy awake.
"It's getting late," she said, pointing to her wristwatch.
Edna stretched and yawned. "I suppose you're right. Mmmmm, nothing like a quick nap… I'm hungry again. I'm going to gain twenty pounds with you two!"
Kathy and Tommy laughed. She nudged Tommy. "Come on, sleepy," she said. "We better be getting back before Mom and Dad start wondering where we are."
"Okay, okay," he said sleepily. They are started to dress.
As they walked back down the beach, feeling the powder-like consistency of the while sand between their toes, Kathy asked Edna, "When can we see you again?"
"Anytime," Tommy said, mimicking Edna. "As long as it's safe!"
Edna laughed, punching the teen playfully on the shoulder. He reeled back in mock pain.
"Really?" Kathy said. "Anytime?"
"Anytime. As I said to Tommy, mum's the word… Your parents mustn't know about what we're doing together, for obvious reasons."
"I promise not to say a thing," Kathy said quickly.
"Good," Edna replied. They all stood in front of her house. "Well, you two better be off. See me after dinner if you like, or tomorrow morning. Just make sure your parents don't become suspicious."
They waved to Edna as they ran down the beach. Edna sighed, then went into her cottage.
CHAPTER SIX
Kathy was thrilled when Margaret told her she would be staying with her and her family for two weeks.
"Are you sure it's okay with your folks?" she asked Kathy after dinner that night. She had arrived earlier that afternoon. "You know my mother, she wanted to make sure I wouldn't be an imposition or anything."
"Don't be silly. Mom and Dad write during the day. They're virtually hermits when they come and stay here, especially now because they have a deadline to meet. You can stay all summer if you want."
"Really?"
"Of course, silly. You know you're welcome here."
"Terrific! I can stay, longer than two weeks if I want to."
"Great! Do you still love me?"
"Of course, I do," Margaret whispered breathlessly. They were both sitting in Kathy's room, her portable TV on low. "That night we were together… I've been thinking of nothing else ever since. Your breasts… your pussy… I hate to think of all the times I've masturbated since you left."
"Tonight, after everyone is asleep, I'll come in your room. It's at the end of the hallway so Tommy won't hear us." Kathy knew her brother wouldn't be bothering them anyway; she had told him she was planning to make it with her girlfriend later that night.
"Are you sure we should… I mean, I'm so hot for you I can hardly stand it, but if we're ever caught…"
"Don't worry. Mom and Dad are sound sleepers and their bedroom is downstairs anyway, under Tommy's room, and he's at the opposite end of the hall from you so there's no way they could hear us. We'll be quiet anyway."
"If you're sure it's alright…"
"I'm sure, don't worry!"
"I'd forgotten how cute your brother is." Margaret said, blushing self-consciously.
Kathy wanted desperately to tell her best friend about her new relationship with her brother, even of Edna, but she didn't dare. She would tell Margaret about Tommy eventually, she knew that, but she was still leery about admitting anything about her secret relationship with Edna. She would have to get the woman's permission for that after she was satisfied that Margaret could keep a secret.
She also wanted to involve Margaret in their lovemaking so they could pair off together. Kathy could tell Tommy was hot for Margaret, and now she was surprised to learn Margaret liked Tommy. But what would Edna and Margaret think of one another?
"He thinks you're cute," Kathy said.
"Really?" she asked, blushing deeper.
"Yes, he's told me so." Kathy insisted.
"He's like a Greek statue… so beautiful. I guess I should say handsome. A guy isn't supposed to be beautiful. But Tommy is!"
"I know what you mean. And he's hung like a bull."
Margaret looked shocked. "How would you know?"
"Oh, I've seen him naked… He likes to swim naked in a lagoon by those rocks I was showing you before. I like to skinny dip too so he's probably seen me naked also."
Margaret gulped. She was becoming excited, aroused.
"He doesn't have any girlfriends, does he?"
"No," Kathy smiled. "We should get together and teach him a few things."
Margaret giggled. "Look who's talking! Neither of us have balled a guy yet. You've told me you have no intention of fucking a guy."
Kathy blushed. "Yes, that's true. But Tommy's different, isn't he?"
"I guess so, but he is your brother, Kathy."
Kathy sighed. "I know, I know. But, let's not think about Tommy. God, I wish my parents would go to bed."
"Yeah, but since they've been working so hard on their book they usually call it a day pretty early. Wait… I hear them, downstairs." She rushed into the hall and leaned over the banister, in time to see her parent's bedroom door close behind them.
She smiled broadly.
