Here it comes! she thought. She closed her eyes, then decided she wanted to see him ejaculating all over her. She threw her belly out, as if giving him a good target. Come on, Tommy, let her rip!
"Aggrrhhh!" he called out, his belly muscles tightening in horizontal ribbons.
His first thick cum wad hit her left tit. More wads followed, splashing on her breasts, arms, belly, thighs and bush. She started to giggle, feeling his oozing cream running down her body. She climaxed, with Edna's tongue constantly flicking against her sensitive clitoris.
Through half closed eyes she watched the expression of ecstasy on her brother's handsome face. Looking down, she saw his swollen prick dance in the hollow of her moving fist.
It was one of the most arousing things she had ever seen. It added immeasurably to the pleasure and prolongation of her own orgasm.
When he had shot the last, of his cum wads, she let go of his prick and he fell back on the bed, his cock twitching madly on his belly.
Then, as if on direct cue, Edna turned the girl around and pressed her back on the bed. She then started licking Tommy's warm cum residue off his sister's body.
"Yes!" Kathy cried ecstatically, "God, that feels delicious!"
"And it tastes delicious," Edna muttered, swallowing Tommy's globs of spunk.
Tommy couldn't believe what he was seeing. He was half inclined to join Edna seeing the expressions on both her and Kathy's face. The girl arched her back when the woman licked the jism from among her wiry pubic hairs. She gasped, her eyes widening suddenly, and Tommy knew she was having an orgasm.
"Goddamn," he murmured to himself. He couldn't take his eyes off Edna, as she greedily slurped up his jism gobs.
When she finished, she licked her lips, smacking them even, leaving Kathy's pubescent body smeared with her saliva.
"You two are really something," he said, shaking his head.
"Mmmmm," Edna remarked. "That did taste good."
"And that felt good!" Kathy added.
Kathy slid over to her brother so their naked bodies were touching. She let her fingers roam up and down his thighs.
"Edna said she'd like Margaret to join us," Tommy told her.
"Really?" Kathy said, looking at the woman for confirmation.
Edna nodded. "Why not? It looks like it's going to happen eventually, especially if she stays with you all summer."
"Oh, she is! That's one reason she went to call her parents," Kathy said.
"Well, I guess that settles it," Edna added.
"I'll tell her tonight," Kathy said.
"And we spend all of tomorrow together," Tommy asserted.
"How about a swim now?" Edna asked. She stood up and stretched. "I must be getting old. All this fucking is making me ache. I haven't had this much exercise in years."
"It's good for you," Tommy said, giggling. He felt his sister's fingers on his limp dick. He kissed her on the mouth, letting his tongue slip between her open lips.
"Or do you two have something else in mind?" Edna asked, a bemused expression on her face.
"Nope," Tommy said, sitting up. "I could do with a little cooling off. How about you, Kathy?"
They all got dressed and were just about to walk out onto the porch when Edna saw Margaret walking in the direction of her house.
"Back in the house," she declared.
Once back inside, Tommy said, "Why don't we just tell her now?"
Remembering the shock Margaret had when she was informed about the unique relationship between Tommy and herself, Kathy said, "I think we better find a better time to tell her." She looked at Tommy and he understood.
"Oh, yeah," he said.
"She's looking for you two," Edna said. "She must be."
The girl was dressed in a pair of shorts and a halter top. Edna guessed she had her bikini on underneath because she was walking toward the racks.
"So much for our swim," Edna said with a sigh.
"Maybe Kathy and I ought to join her anyway. We wouldn't want her going back to the house and telling Mom and Dad she couldn't find us."
Tommy looked at Edna for confirmation.
"Yes," Edna agreed. "You're right."
"We'll talk to her tonight," Tommy said. "She's going to like the idea, I just know it."
"All right." Edna smiled, kissing the boy and girl. "You two better catch up with her before she starts back toward your house. Then she'll know you were here with me."
Kathy grinned. "She'll know about that soon enough."
With that said, the two teens – brother and sister – ran to the lagoon, and Edna watched them disappear below the uneven level of rocks.
She sighed, her hand absently slipping into her bikini briefs to comb through her thick matted pubic hairs. She was anticipating the pleasure the four of them would enjoy together, all the exciting variations they could indulge themselves in. There was virtually an endless variety of positions they could explore!
And now that Kathy had introduced her to the pleasures of making love to another member of her own sex – something she had never even thought of doing before – Edna couldn't wait to see what Margaret was like in bed.
Was she just as playful, just as willing and eager as Kathy and Tommy? And think of the fun Tommy would now have, with two cute girls and an older woman to make love to.
A beautiful older woman, Edna thought to herself, smiling. I must have something to attract all these teens. And to keep them coming back for more! Thank God, Tommy and Kathy don't come from a big family, or have a lot of friends here, because the house would be overflowing with writhing, naked teens.
As it is, I have my hands full!
Edna went into the kitchen and poured a large glass of ice tea. She brought it out onto the back porch and sat down in her canvas chair. Gazing peacefully out onto the ocean, she sipped slowly from the glass, enjoying the slightly bitter taste of the tea.
She just finished draining the last of the tea when she heard a knock on her front doer.
Now who the hell can that be? she thought, her heart skipping a beat. She imagined Tommy's and Kathy's parents standing there, the police not far behind. I think I'm getting paranoid, she thought.
She opened the door and was surprised to see Kathy, Tommy and, just behind them, as if shyly trying to stay out of sight, Margaret. None of them were even wet.
What's going on? she wondered.
"We couldn't wait," Tommy said, grinning. "Edna, we'd like you to meet Margaret." Margaret formally offered her hand and Edna shook it. She felt as if she was in a daze.
"We decided not to wait until tonight to tell Margaret everything," Kathy said. "I just hope your bed is big enough for all of us."
Edna smiled and ushered them into her house. "Well, I guess we're going to have to find out," she said, closing the door behind them.
