“Alex, would you like to come in?” said Angela Wilson, inviting the teen sitting in the waiting room into her office. It was the third week of sessions with the O’Connell family. Angela had gathered at lot background information that had confirmed her initial impressions. Alexandra, that is Alex, and Zach were typical teens exploring their sexuality for the first time, only they were doing it with each other instead of with friends. Fourteen-year-old Molly was innocent when it came to sex, but she was clearly interested in it, perhaps even more than her siblings. Charles didn’t seem to have any particular incestuous leanings, but he had a secret. Angela thought it was bisexuality, but she wasn’t sure yet. And Priscilla, Pris, was a roiling mess of lust. She clearly had the hots for her son, and maybe for Alex, too, but she couldn’t bring herself to admit it, not to herself and certainly not to her therapist.
It was finally time to get to the heart of the matter. She had established a rapport with the fifteen-year-old girl, who had become remarkably open about just about everything. Everything except the reason why she was here.
“Alex, I’ve been waiting for you to bring it up. It’s kind of an elephant in the room. You know why we’re here, don’t you?”
“It’s because I had sex with my brother.”
“Yes. Now, was it consensual? Was it something you wanted to do?”
Alex nodded.
“Why did you have sex with Zach?”
“I dunno.”
“Now, come on. There had to be a reason. Are you in love with him? I mean more than just brother and sister? Or were you bored? Or just plain horny?”
Alex smiled at this last. “I guess we were just fooling around, and somehow it became serious.”
“Tell me about it, the first time.”
Alex told about how she and Zach were just bored and hanging out in his room, lying on his bed, both staring at the ceiling. How she started teasing him about how he had a crush on Zoe next door but that he was too scared to do anything about it. At first, Alex gave only a cursory summary, but Angela pressed her for details, saying that it was healthy to speak openly about sex when in appropriate places, like therapy. So with prompting, Alex gave a somewhat detailed account, and Angela filled in the rest with reasonable inferences.
“I’m not scared,” Zach had said.
“I bet you wouldn’t know what to do, anyway.”
“I do, too.”
Alex turned and put her face close to his. “What would you do if you were this close to her?”
“Come on, sis.”
“No, serious. What you do with a girl who was this close to you?” Alex was suddenly struck by how good-looking her brother was. She had always known he was a cute guy, but with his face inches away from hers, he suddenly looked hot.
“Get away.” He half-heartedly tried to push his sister away, but she resisted.
“I bet you’ve never kissed a girl.”
“I have, too. You know I have.”
That much was true, Alex knew. “Maybe so, but that doesn’t mean you know what to do with a girl. Have you ever gotten to second base?”
Alex could feel her brother’s breath on her face. Then without conscious will, the two teens leaned in and kissed.
It may not have been Zach’s first kiss, but it was Alex’s. Their lips parted, and their tongues touched. He tasted good. Alex shivered with desire.
Zach broke away. “What was that?”
Alex shrugged. “Did you like it?”
He nodded.
She reached out and placed her hand on the back of his neck, pulling her brother in for another kiss. She didn’t know what she was doing, or why, but she knew she wanted more.
They kissed for a while, running their hands over each other’s body. Alex shivered again when Zach cupped her breasts. She could feel his boner through his pants. That excited her even more and gave her a wicked thought. She broke the kiss and started planting kisses on his neck and chest, working her way down his torso.
“Sis, what are you doing?”
“I want to see it.”
“See what?” Then Zach realized what she meant as her kisses reached his crotch.
She unbuttoned his pants and unzipped his fly. She could see the outline of his cock straining against his underwear. It was bigger than she had imagined. She tugged his underwear down around his thighs, and his cock popped up.
“Oh, wow!” she said, seeing her first erect cock. It was funny looking with its bulbous head, but strangely enticing, nevertheless. She reached out and took it in one hand. It was stiff but with a soft and yielding surface. A drop of liquid glistened at the hole in the head.
She started to rub her hand up and down along the shaft. That was what boys did to pleasure themselves, wasn’t it?
Suddenly Zach moaned, and a spurts of white liquid shot several inches in the air, mostly landing on her hand. She gasped, at first not comprehending what she had done. Then she realized that she had made her brother cum.
She looked at the semen on her hand. She sniffed it. It smelled funky, but nice. Tentatively, she extended her tongue and tasted it. Salty. She looked at Zach, who was staring back at her. Then, smiling, she started licking the cum off of her hand. Zach’s mouth was agape in disbelief at what his little sister was doing.
When she was done, she moved back up and kissed her brother again.
He stopped her.
“This is wrong.”
“Doesn’t feel wrong to me.”
He pulled her tightly into him and started kissing her again. She wanted her brother, and the fact that he wanted her excited her all the more.
“You saw mine,” he said, breaking the kiss once again. “Can I see yours?”
Alex, giggled, sat up and pulled off her T-shirt. Then reaching around her back, unhooked her bra and slipped it off, exposing her breasts to the boy.
Zach’s eyes went wide. “Can I kiss them?”
“Oh, yes.”
He leaned in and took her left nipple into his mouth. Alex shuddered as a bolt of pleasure traveled from her breast down to her crotch. God, it felt good. He moved to the other breast, and another bolt ran through her.
Then he sat up, put his hands on her waist, and began to tug her sweatpants and panties down. When he got them off, Zach gently spread her legs as he lowered his face to her crotch. Even though she had never felt a tongue on her pussy before, she knew what was coming.
The touch of his mouth to her clit was electric. She moaned and closed her eyes, enjoying the sensation of his wet tongue lapping at her clit and labia. She had played with herself before, bringing herself to orgasm, but that had never been as pleasurable than this. She felt the orgasm welling up insider her when suddenly he stopped.
She opened her eyes and looked down at him. He returned her gaze and said, “Can I stick a finger in?”
She nodded yes, biting her lower lip.
She closed her eyes and felt his fingers run along her slit. She quivered. Then, slowly she felt a finger penetrate her. In her masturbatory sessions, she had been afraid to penetrate herself, but now that it had happened, it felt good. She wondered if this was what a penis felt like. If so, she couldn’t wait to get fucked. Then she felt a second finger enter her, and that felt even better as her virgin vagina was being stretched for the first time.
Then Zach began to slowly move his fingers in a circle while his mouth returned to her clit. The impending orgasm returned, a crescendo building until it washed over her. She moaned again, more loudly, and convulsed hard, throwing his mouth off of her. The pleasure was too intense. She closed her legs and rocked as wave after wave passed through her body, slowly diminishing in intensity with each one.
She opened her eyes and looked down at her brother again. He was smiling. She reached out and took his head into her hands, gently guiding him up to her face. They kissed.
“I’ve never felt anything like that,” she said.
“Me neither.”
“I didn’t think you’d been with a girl. Where did you learn to do that?”
“Porn.”
She glanced at the alarm clock next to the bed. “Mom will be home soon. We better get dressed.”
He started to move off of her when she stopped him.
“Next time, I want you to fuck me.”
Zach’s eyes went wide. Next time?! Fucking?! Then he leaned in and kissed his sister again. Then the pair got dressed and waited for the rest of the family to come home.
“That was your first time with a boy?” Angela asked.
Alex nodded.
“You mean you hadn’t fooled around with anyone before? Not even some necking?”
“No. He was my first. My only.”
“But it wasn’t your first orgasm.”
“No.”
“Before this, did you masturbate a lot?”
“Not a lot, but sometimes.”
“Since you and Zach started having sex, have you been masturbating more?”
Alex nodded.
“When you masturbated before, did you think about Zach?”
She shook her head, no.
“Who did you think about?”
Alex hesitated before saying, “Other boys from school.”
Angela picked up on the teen’s hesitation. “Other girls?”
Alex nodded again, looking a bit sheepish.
“It’s nothing to be ashamed of. Same-sex attraction, especially in women, is fairly common. Did you ever imagine sex with Zach before you had it?”
“No.”
“Any other family members, your dad, for instance.”
“Sort of. Not when I played with myself, but sometimes I wish my dad was holding and kissing me.”
“What about your mother? Or Molly?”
“No, not really.”
“So the other girls you fantasized about, they were friends from school.”
She nodded sheepishly.
“Again, all this is nothing to be ashamed of. There’s nothing wrong with thoughts. Thoughts are harmless. You can think and fantasize about anything. You haven’t done anything that a lot of other people haven’t done. That includes most of your friends from school.”
“Most people don’t have sex with their brother.”
“More than you would think,” said Angela. “Now, has talking about you and Zach did made you excited?”
The girl nodded again.
“To tell you the truth, it has got me a little excited.”
Alex looked at the therapist, noticing for the first time how sexy she was, curvy with really big boobs that strained against her blouse, which was a size too small.
Angela, having deliberately dropped the hint, noticed the look it engendered but let it pass. Best to proceed slowly. “We’re about at the end of our session. We’ll pick up where we left off next time. But I want you to remember that everything that is said here is confidential. I’m not going to tell your parents, or Zach. That is, unless you want me to. And you don’t have to tell them either.”
“I can tell them?”
“Only if you want to. If they ask and you don’t want to, then tell them I said it was private.”
The next afternoon when Angela opened the door to her waiting room to invite Zach in. Angela had lusted after him from the first time she had seen him. He was an adonis. At sixteen he still had some growing to do, but he had a trim, athletic body, short, light brown hair, and beautiful blue eyes. It was no wonder his sister fell for him. But she had restrained her lust.
Zach, like all boys, had been more reticent about opening up than his sister had been. Alex as a Type A, assertive and extroverted; he was more of a follower, introverted. But in the past three weeks she had gotten him to a point where he had begun talking about emotions and private matters. As with the previous day’s session with Alex, now was the time to get to the point.
As she had with his sister, she asked him directly about their first sexual encounter. After some cajoling he opened up. His story pretty much concurred with hers.
“But that wasn’t the only time you had sex.”
“No, the next day we did it again.”
“Tell me about it.”
Zach and Alex got home from school the next afternoon and found themselves alone in the house. Their parents were at work, and Molly had stayed late for drama club.
“We’re alone,” Zach said to Alex.
“Yeah, what of it?”
“Do you want to, you know, play some more?”
Alex smiled, “I wasn’t sure you wanted to do it again.”
“Hell, yeah!”
She just stood there, looking at him. After a moment he got the hint and moved in close. He could feel her breath on his face, like the other day, and he could feel is cock stir to hardness. He leaned in and kissed her. She returned it, and they embraced, her hands finding their way down cup his buttocks. That felt nice.
After a few moments she broke the kiss. Hooking a finger into one of his beltloops she led him upstairs to her bedroom. Once inside, they began kissing again, crushing their bodies against one another. Zach could feel his sister’s breasts pushing into his chest.
Then she stopped, dropped to her knees, and started unbuckling his belt and undoing his fly. She tugged his pants and underwear down, and his cock popped up.
“There it is,” she said. Then looking up at him and smiling she said, “You’re not the only one who’s seen porn.”
And with that she took his cock into her mouth. Zach watched as his sister engulfed the head and most of the five-inch shaft. It felt incredible, like nothing he’d ever felt before. She bobbed her head up and down a few times before he exploded, pumping semen into her mouth. She caught most of it, but some dribbled out onto her chin. He watched as she scooped it up with a finger and deposited it into her mouth.
“You taste good, you know that?”
Then she started taking off her clothes. Zach watched his sister strip and then climb onto the bed.
“What are you waiting for? I want you to eat me again.”
With that, Zach stripped, a bit self-consciously as his sister was watching. But he found that her gaze was something of a turn on. He’d looked lustfully at girls in school, but for the first time he was experiencing what it was like to be looked at in that way. The fact that it was his sister doing the looking made it more wicked and exciting.
Once undressed, he climbed onto the bed as Alex spread her legs. He leaned down, and this time, instead of diving in with his tongue right away, he took a good look at her pussy. It was topped with a small triangle of dark hair, but otherwise hairless. The inner lips were emerging pink from the folds, like an orchid, and there was what looked like a little cock head that was her clit.
He gently spread her lips with his fingers, and only then did he start to take a few tentative laps with his tongue. She sighed deeply, closed her eyes, and put her head back onto the pillow. He lapped upwards, then circled her clit with the tip of his tongue. She shuddered. He continued to lick until he felt her tense up.
“Oh, God! Oh, God!” she almost yelled as her thighs quivered and she ground her pussy into his face. He latched onto her clit with his lips, and she yelled something unintelligible and started bucking. She grabbed his head and held him in place as she ground her way through her orgasm against his lips and tongue.
When she finished shaking, Zach moved up, and brother and sister kissed once again. His cock was hard again, and as their tongues entwined, he started to grind his cock against her pussy. The folds, now slick with his saliva and her juices, felt good against his shaft. Having cum once, it was taking longer for him to cum a second time, and he was enjoying the feeling and then the tip of his cock slipped between her labia.
Alex broke the kiss and gasped. Zach realized he was fucking, or at least on the verge of fucking, his sister. He looked at Alex, and there was an expression of shock and fear on her face, an expression that was mingled with desire. Despite what she had said the day before, she fucking her brother might be a step too far.
His cock slipped half an inch deeper. He didn’t mean it to, or maybe he did.
Then Alex said, “Yes, fuck me. I want you.” All second thoughts were gone with the feeling of his cock half inside her.
He hesitated no longer and thrust deep inside his sister. She whimpered. The feeling was like nothing he’d ever felt. Better than getting a blowjob, way better than jerking off. He pulled back and thrust again. Then again, building up a steady rhythm. For her part, Alex ground against him, instinctively trying to match his strokes.
He leaned down and kissed her again as he continued to fuck her. The rhythm of the thrusting grew erratic as the kissing and Alex’s grinding threw the pair out of sync. But it still felt good.
Alex broke the kiss and groaned, “Oh, God! Oh, God! Yes, fuck me! Fuck me!” Then her words degenerated into meaningless sounds as her body shuddered as she came again.
Then he felt he warm rush of semen stream through his cock as he pumped his seed deep into Alex’s womb.
He deflated and slipped out of her, and he collapsed next to his sister.
They lay there for a minute. Then Alex said, “Oh, God, that was fantastic!”
Zach finished his account and grew quiet. From her perspective, Angela was learning a lot about the pair. The teens’ two stories matched nearly perfectly. The two were both rather uninhibited but inexperienced. They knew the basics but were still exploring. One thing was certain; they were both turned on by the thought of incest. And of the pair, it was Alex who took the lead. Zach would be easy to manipulate. Dangle a pussy in front of him, either Thea’s or her own, and he could be led anywhere. The only question was whether or not he had any bi tendencies. It would be more fun if he did, but it wasn’t essential for her plan.
Alex would be less easy to lead. But she clearly enjoyed sex and wanted more. She clearly had a thing for her brother, and Angela had yet to meet a girl who had the hots for her brother who didn’t want to also fuck her father. Her husband Bill would serve nicely as a proxy for Alex’s own dad.
These two teens could be brought along. The question was the other three family members.
Wednesday was Molly’s session. From the beginning, Angela was taken in by the girl. She was a little slip of a thing, light-brown hair like her brother and mother, but tiny breasts, just the hint of curve in her hips. Molly had been chatty in previous sessions, but there was a nervousness behind a gregarious exterior. Molly clearly knew why they were here, but didn’t know how to bring it up.
“Do you know why you’re here?”
Molly nodded.
“Can you tell me?”
“It’s because Zach and Alex had sex.”
“That’s right. I just want to make sure everything is right with you. How did you find out?”
The fourteen-year-old hesitated then said, “I saw them.”
“You saw them have sex?”
She nodded.
“How did that make you feel?”
Molly looked down and didn’t answer.
“It’s okay. You should never be embarrassed or ashamed of feelings. However it made you feel is okay.”
The girl took a while to answer. “It made me feel funny.”
“Funny how?”
“Funny down there.” She glanced at her lap. “Like when I’m thinking about kissing a boy.”
“Have you ever kissed a boy?”
She shook her head, no.
“You don’t need to be embarrassed or ashamed about that. You just became sexually excited. Horny.” Angela paused, and Molly smiled at hearing an adult use that word. Angela continued, “That’s perfectly normal. Most people get excited when watching other people have sex. That’s why there’s porn. Have you ever watched porn, by the way?”
She shook her head again.
“Never?”
“No.”
“How long did you watch your brother and sister?”
“For a while. Then I got scared they might see me.”
“That’s understandable. Do you have any questions about what you saw?”
“Zach put his face ... down there,” she said looking down again at her lap at that last. Isn’t that weird?”
Pris had told Angela that they’d had the sex talk with Molly, but evidently, she had just covered the reproductive minimum. The girl clearly had a lot to learn about sex for pleasure. “Not at all. It’s just oral sex. Cunnilingus is the technical term. It gives the woman pleasure.”
“I thought oral sex was a blow job.”
“So you know what a blow job is? Did you see Alex do that to Zach?”
Molly nodded yes eagerly. Angela could see the girl’s nervousness and reticence melting away.
“Well, cunnilingus is just when a man, or a woman for that matter, performs oral sex on a woman.”
Molly screwed her face up. “Isn’t it kinda icky?”
“Not at all. It’s beautiful, both to give and receive.”
“You mean, you’ve...”
