Edna looked at Tommy, then back to Kathy. "Your brother turns you on, doesn't he?"
Kathy nodded. Tommy smiled proudly, but he was confused. He never thought his sister thought of him in that way. He had often thought of her in just those same terms, but had never had the balls to tell her.
"This could be interesting," Edna said under her breath.
"Tommy, lam sorry. I wasn't setting out to spy on you intentionally, and I promise not to tell Mom or Dad, but when I saw you and… and…"
"Edna," Edna offered.
"You and Edna kissing like you were out front, then I knew something funny was going on. I just had to see."
"We understand," Edna said soothingly.
"You do?" Kathy said brightly.
Edna nodded. "The three of us could have a lot of fun together."
"I'd like that!" Kathy said, meaning every word of it.
"I bet you would. You're a very pretty girl, Kathy."
"And you're beautiful," the girl gushed.
Edna brushed her fingers across Kathy's cheek. The girl smiled. Edna had never been sexually attracted to young girls before but she thought in Kathy's case she could make an exception. The girl did arouse her, and no other girl had ever done that to her before. There was something about her…
"Tommy's mentioned you don't have any girlfriends," Edna said, stroking the girl's bare shoulder.
"I-I don't," she stammered.
"Don't you like boys?" Edna probed.
"No," she said, smiling shyly at Tommy. "Except for Tommy."
"You're a virgin."
Tommy felt his cock stiffening at the thought of taking his own sister's cherry. The thought had crossed his mind before, mostly when he masturbated, but now that he realized his sister probably wanted him too, he started to tremble in anticipation.
"You want to make it with Tommy?"
Kathy nodded. Then she whispered, so just Edna would hear, "And with you too."
Edna felt the same stirring excitement that Tommy did.
This could indeed be very interesting, she thought, imagining what it would be like making love to such a pretty girl, something she had never done before. I bet Kathy has made love to a few girls already… that would explain her apparent disinterest in boys.
Edna wanted to be left alone with Kathy, but she would have to admit to Tommy that his sister was just as interested in making love to her as she was him, which Kathy obviously didn't want Tommy to know. At least not yet. He would have to know sooner or later if she and Edna went through with it, though.
"Do you want to be alone with your brother first for a little while?" Edna whispered to her. Tommy leaned forward in his chair by the couch to try to catch the woman's words, but he couldn't quite make them out. Then Edna shooed him away.
"I'd rather be alone with you first, Edna," she whispered back.
"Then you'll have to tell Tommy that. Perhaps it would be better if you did now anyway. He won't say anything to anyone."
"Do you really think I should. He's never suspected I like girls… that way."
Edna nodded. "I'm sure he'll understand. He's grown up quite a lot in the past couple of weeks."
Kathy told him.
"Wow," he said, grinning. "This is really getting kinky! Can I at least watch?"
Kathy looked at Edna. "No," Edna said. "Not this first time. Later. But give us both a little privacy now."
He shrugged. "Okay. We'll have something to look forward to."
"You'll have something else to look forward to when we're finished," Edna said, looking at Kathy.
"Mmmm," Tommy said, nodding. "Okay, how about if we go for a swim, then come back in a bit."
"Good idea," she approved. "Knock on my door first before entering."
"Okay. Have fun!" And he raced out the back door, toward the rocks.
Kathy shook her head. "Everything is happening so fast. Just last night I was looking forward to my girlfriend coming next week and here I am about to make it with you. Then with Tommy! I just can't believe it!"
Edna chuckled, her blood boiling. The more she looked at the girl, her slim figure, her uplifted tits, the promise of her tender snatch, the more aroused she became. She didn't even question her sudden desire to make love to a young girl. Maybe because she was Tommy's sister and, in fact, looked a lot like him. In any event, she wanted to do it with her.
She stood up and offered the girl her hand. Kathy took it and they walked into Edna's bedroom.
"I'm really sorry I upset you… I really didn't mean to spy on you. I'm not like that," Kathy insisted.
"I know. Maybe it's all for the best. Under the circumstances some sort of confrontation was inevitable anyway. Tommy couldn't have gone the whole summer sneaking away from you. He might fool your parents but not you. You're both too close to each other, I can see that."
"He is handsome, isn't he?"
"My God, yes! That's an understatement if ever I heard one!"
"And… and his cock… it's enormous!" Kathy said, giggling and blushing.
"It certainly is!"
"It's so big I was surprised it fit. When he fucked you I mean."
"He's the best thing that's happened to me in a long time." Edna told Kathy about losing her husband and how she felt the first time she saw Tommy, then how she felt the first time they had made love together.
She made it sound so natural – so normal, despite the gap in their ages – that Kathy was quite touched.
"You're his first woman?" Kathy asked.
"Oh, yes. I took his cherry. And, a sense, you'll be taking mine."
Kathy looked puzzled. "What do you mean?"
"I've never made love to any… woman… before."
"Really? But I thought you had. You were so willing to make it with me."
"I know, but I've never felt that way before. You're different… beautiful… and I do want very much to make love to you, Kathy."
Kathy beamed with pleasure. "I can see why Tommy obviously thinks so much about you. I feel very comfortable with you, like I've known you all my life."
"I'm glad."
Thea they kissed. Kathy didn't hesitate to thrust her tongue between Edna's lips. Edna felt the girl's hand on her breasts and responded accordingly. Before long they were French kissing passionately, both of them becoming more and more turned on.
Taking on the role of teacher, Kathy began undressing Edna. Amused and excited, Edna submitted completely.
"I've never felt this way before." Kathy gushed. "So… so hot!"
Edna unclasped the girl's bikini bra, revealing Kathy's nubile tits. Her eyes widened with pleasure.
Kathy caressed Edna's melon-like tits while the woman's trembling hands ran up and down her body. She lifted her ass up off the bed so Edna could remove her bikini briefs. The girl's cunt hair, was nowhere as thick as Edna's.
"I want to go down on you," Kathy whispered.
"Yes, my sweet, yes, yes…" Edna leaned back and spread her legs. Her back arched sharply the instant Kathy's tongue touched her clitoris. The girl's tongue swooped around the hanging knob of flesh, caressing it gently, probing until Edna's cunt filled with her cream. Then Kathy started swallowing.
Edna covered her eyes with the back of her hand, letting the waves of pleasure roll over her body.
The girl had obviously done this before. She knew where to touch and for how long. Sparks of desire ignited deep inside the woman's cunt. Her clit became so swollen it felt like a fist inside of her. Kathy's tongue flicked and massaged and made her cream like a raging river.
She had never felt anything quite as exhilarating. Making love to this girl is going to be a real treat, she thought, her belly quivering as the pressure steadily built up inside her.
She combed her fingers through the girl's blonde hair, then pressed down on her head, forcing her tongue as deep into her twat as it could possibly go. It felt like a lizard inside her, something moving constantly, sweeping over her cuntal walls, producing the sweetest fuck sensations imaginable.
