Family Learning

Story:
It was another lazy summer afternoon as Brianna and Courtney relaxed by their pool, soaking up some sun and having some girl time. They were sisters and even with their age gap, Brianna being sixteen and Courtney being 12, they were easily each other’s most trusted friend. Their brother John was upstairs in his room, on the computer.
“Bri?” Courtney asked, stretching her short, slim body out on the deck.
“Yeah Court?” Brianna responded, turning over to face her sister. Brianna wasn’t as slim or tan as her younger sister but had beautiful 32 C breasts to make up for it and their dark brown eyes and hair were almost identical.
“I know we talk about everything but…” Courtney’s voice trailed off nervously.
“No buts! You can ask me anything little sis.”
“Well, I know that since Mom and Dad are getting back in town on Monday you were planning on having a party Saturday night. I kind of have a friend I wanted to invite.”
Brianna laughed. “You were nervous about asking that? Of course you can have your friends come over. There’s plenty of booze to go around.”
“That’s just the first part though,” Courtney said, sounding a little more nervous now. “It’s a guy. That I really like. I don’t really know how to, you know, do anything.”
“Well, I’m glad you came to me,” a little surprised by the question but happy to help her sister out. “What do you think you’re ready to do?”
“Well I’m not having sex!” Courtney exclaimed loudly. “But I do want to, you know, turn him on and stuff. And give him a bj.”
“I think that’s plenty for you right now,” Brianna said with a chuckle. “You’re still starting before I did though! I was 13 when I gave head the first time, and 14 before I had sex.”
“Yeah but I’m almost 13, and once you started having sex it’s not like you ever stopped,” Courtney retorted playfully.
Brianna stuck her tongue out at the jab at her promiscuity, but didn’t even try to argue it. “I know, I think you’re ready. So what, you want me to give you lessons or something?”
“Would you? That’d be fantastic! I really don’t want to mess this up.”
“Well, for guys head is like pizza. Even if you mess it up, bad pizza is still pizza. But good pizza is great pizza so sure, I’ll teach you how to do it right. Be right back.”
Brianna walked inside and looked around for the most phallic object she could find, finally settling on an appropriate if stereotypical banana. She walked back out and handed it to Courtney.
“Now this is going to be a little weird but just go with me” Brianna said, quickly coming up with a crash course in oral. “Stand up and hold this between your legs. I’m going to be you and you’re going to be the guy.”
“Ok…” Courtney said slowly, a little weirded out by the plan but knowing it was worth it for a lesson from a master like her sister. She stood up and held the banana between her legs with her thighs, placing her hands on her hips.
“Alright, now the first thing you have to know is position. ALL guys love it when you get on your knees in front of them. The first couple times feel a little demeaning but they love it so much you get used to it.” Brianna knelt down in front of her sister, the banana hanging inches in front of her face.
“Next you stroke it with your hand, lightly.” Brianna demonstrated, taking care not to rip it out from between her sister’s thighs.
“Then you lick it up and down. Take the head in your mouth and play with it with your tounge. Guys love that.” Again Brianna demonstrated to the observant Courtney, licking the bottom of the banana and then both sides before taking the end of the banana in her mouth, looking up at Courtney to make sure she was playing close attention.
“Finally you bob your head up and down, using your lips and tongue.” She wasn’t able to get much of the banana in her mouth because of how wide it was, but Brianna did her best to demonstrate, applying pressure with her lips and licking the shaft with her tongue. She then climbed to her feet.
“That’s probably all you’ll have to do. Guys around your age are easy,” she said with a laugh. “You want to try?”
“Sure!” Courtney said, excited to show her sister that she had been listening. She handed the banana to Brianna who placed it between her legs just as Courtney had.
“Ok, first get into position.” Brianna instructed. As Courtney dropped to her knees Brianna suddenly felt a little self conscious about what she was teaching her twelve year old sister to do, but figuring she was better off learning from another woman than the nasty videos online.
“Now stroke it a little bit.” Courtney grabbed onto the banana a little too hard, almost unwedging it from Brianna thighs, but quickly realized her mistake and loosened her grip, running her hand up and down it gently.
“Like this?” Courtney asked, hoping her screw up hadn’t been too bad.
“Perfect. Now lick it. You don’t have to be too gentle with this part, but don’t get too rough.”
Courtney nodded, a little confused by the instructions but hoping she would figure it out in time. She licked all the way up to the shaft, stopping only a fraction of an inch from her sister’s thigh, then back down. Brianna felt the moisture from her tongue and would have been a liar to say it didn’t excite her a little bit, but focused on the task at hand.
“Great… Great. Now take the head in your mouth bob it up and down and that’s that.” Brianna said, having to collect herself just a little.
Courtney nodded silently and went to work, but could barely fit any of the banana in her mouth. She tried though, and after a couple minutes Brianna patted her on the head and pulled the banana out from between her legs.
“Good job. That ought to blow any 12 year old’s mind,” Brianna said with a smile.
Courtney rose to her feet, looking nervous yet again. “Actually, there’s something I didn’t really tell you. My friend… he’s not 12. He’s actually 15.”
Brianna looked a little surprised but, again, felt a little proud of her sister. “An older man? Already? You little slut!” she said with a smile. “That’s fine, but… you’re probably not going to be his first then. I don’t really know any other way to practice though.”
Courtney and Brianna sat back down on the deck, racking their brains to try and figure out another way that Courtney could get better before the big day. Bananas worked ok, and Briana had a dildo that, after heavy washing, Courtney could practice on, but nothing really acted like the real thing. Finally a light bulb popped on in Courtney’s head.
“Ok, don’t call me crazy on this one,” she said, knowing it was a risky idea but potentially worth it. “I know it would be weird but… what if we asked John to help us?”
Brianna’s jaw dropped and her eyes opened wide, shocked that her little sister wanted their seventeen year old brother to help them with something like this. They’d always gotten along fine but weren’t nearly as close as Brianna and Courtney were, and… it was her brother!
“Court… I don’t know. I mean, he’s our brother! What if he says no and tells mom and dad? Or what if he says yes and we have to… ugh.” Brianna said. “I mean, he’s cute, and if he weren’t our brother I’d be fine with it.
