Karina looked in the full-length mirror in the dressing room. She couldn’t believe this was really happening. She had been a virgin less than a year ago and now was getting ready to take part in the premier amateur sex contest in Caradoc. Her brothers were there with her, but they were three years older; it probably didn’t mean as much to them. To her, it was pretty amazing, and most amazing of all - she had been so scared of popping her cherry!
Ten Months Earlier
“Mom?”
Korona looked over at her daughter. She had just turned fourteen and looked so young, but also so beautiful. She was going to be a real heartbreaker once she grew up a little bit more. She looked like her mother, but Korona wasn’t sure if she was going to be as tall or as buxom as she was. “Yes, honey.”
“Uh...”
“What?”
“Whatissexlike?” came tumbling out in almost a single syllable.
“Excuse me?” Korona almost didn’t recognize what Karina was asking. What was sex like?
Karina took a deep breath and repeated her question at a slower pace. “What is sex like?”
Her mother blinked at that. How did she answer a question that was, in a way, the toughest question in human history? Maybe she could defer the question. “Uh ... why?”
“Well, this Friday I’ve been invited to a party after school at Jenny Mathin’s and she said it was going to be a grownup sort of party.” She noticed her mother eyeing her curiously and she added, “Everybody would be having sex.”
“Oh!” Korona remembered those days back in Goldheart. People might not have been running around half naked, but they were having just as much sex as they did on Lupina. She smiled as she thought of the first party she’d attended. She had been a virgin at the beginning and an expert at the end! Still, as a teacher she knew that some teens were more nervous than others. Time to ask a few questions. “Karina, can I ask you how much you’ve done?”
Her daughter blushed and stammered. “Uh...” Karina couldn’t say what she had done already.
“Would you prefer talking to your father?”
“NO!”
“Okay. What about one of your teachers or somebody else”
Karina thought about that. “Uh, maybe.”
Korona nodded. “Have you heard about the mentorship program at school. Some students are like you, a little nervous about their first time. Some aren’t...”
“Like Paul and Kyle!”
“ ... like Paul and Kyle.” She knew her sons had been very eager to learn, and not at all nervous. “However, some boys are as nervous as some girls. Give me a minute.”
Korona tapped her macrolink and linked to the school’s site. She remembered learning about a mentorship program that the school offered to help kids learn about adult topics when they felt uneasy about talking to a family member or teacher. Their fellow students were hardly the most accurate or reliable sources of information. There was a list of possible adult mentors, and as she looked down the list, she recognized a pair of names, Johan and Mary Tannhauser. They were a few years older than she and Jonathan, maybe sixty years old, barely middle-aged in a society where the average life span was over one-forty. They were very pleasant and pleasantly sexy. They had partied with them once after a school event for the boys and she thought they might be good teachers for her nervous daughter.
Korona turned back to Karina. “How about I make a phone call to somebody your father and I know. They are very nice people and might just be able to answer all your questions.” Karina eyed her mother, who continued, “Sex is wonderful and it’s a very important part of life. I want you to enjoy sex as much as I do, and I enjoy it a lot!”
Karina giggled at that. “I know! I’ve seen and heard you and Dad going at it!”
Korona laughed at that. “Very true. So, the question is, would you like some answers to your questions? I can promise they won’t tell us what you asked them, or what they answered.”
Karina nodded. “Uh, sure.”
“Okay. Let me make a few calls and sort this out.”
“Thanks, Mom!” Karina hugged her mother and went to her bedroom. She had the small bedroom, and her twin brothers shared the large one.
Korona sent a message to the Tannhausers asking if they were still involved in the mentorship program and if they might be interested in helping her daughter. Later that evening, after dinner, they called and answered yes to both questions. Korona told her daughter to come home after school on Friday; if anybody asked why she couldn’t go to the party she was to explain she had a family obligation.
Then she told Jonathan what had transpired. He had a good laugh and agreed to his wife’s plan. Then they spent a very enjoyable evening telling each other and demonstrating how they had learned about sex.
That Friday, Karina came home on the school autobus by herself. Korona had already checked, and her sons would be at their own school afterparty. She told Karina to clean up and then took her in their autovan to the Tannhauser’s home. They got out and went up the walkway to the house. Mary Tannhauser answered the door. “Korona! So good to see you again!”
“Mary! Thank you! This is our daughter, Karina.”
“Well, come in, come in. Johan and I were looking forward to meeting you. You are just the spitting image of your mother. Come in!” She held the door open and stepped aside.
Whatever Karina was expecting didn’t happen right away. Both she and her mother were wearing typical outdoor wear of short wraps and slip-on shoes. So was Mary, though she was barefoot, and Johan was wearing a wrap when he came in a few minutes later. Nobody was talking about sex at all; instead they all sat around the kitchen island and drank iced tea.
Then Korona stood. “I need to get home. No kids tonight, so Jon and I are going out to dinner.”
“Sounds nice,” commented Mary. “Where are you going?”
“Anthony’s, down on the Riverwalk.” The Riverwalk was aptly named, since it was a very upscale restaurant, nightclub, and park area along the Dravid River, cutting through a very nice section of Caradoc. The river wasn’t all that big, but for several kilometers there were walkways on both banks of the river, pedestrian bridges every few hundred meters, and water taxis that crisscrossed between the banks, and went up and down the river.
“Very nice!” said Johan. “Mary and I went there last year. Lots of places to go after dinner. Anthony’s also has a very nice lounge for relaxing after dinner, too.” He waggled his eyebrows.
That went over Karina’s head, but Korona smiled and nodded. The Riverwalk had lots of public benches and private alcoves suitable for after-dinner and after-drink romantic interludes, or just plain sex! Korona was going to dress up and enjoy her night out without the kids!
“So, Karina, your mom said you were a bit nervous about what would happen tonight if you went to the party at school?” said Mary. Johan had wandered off to the back of the house, where they could hear him puttering around. “What are you up to, babe?” yelled Mary.
He yelled back, “Prepping for dinner!”
Mary nodded and said, “We’re doing barbecued hamburgers. Is that okay? Your mom said that was okay with you.”
“Sure.”
“Good. So, the party?”
Karina nodded. She felt very comfortable with Mary, though she was happy Johan wasn’t around. “Did Mom tell you why?”
“Why don’t you explain it to me.”
“Well, there’s a party tonight and I was told I was sort of expected to have sex. I just haven’t done that before.”
“That’s what your mom told me. So, ask away. Johan will stay away until we tell him to come back in. Mind if I get more comfortable?” With that, Mary stood up and undid the magnetic clasp on her waist wrap, tossing it to the side. She was about Karina’s mom’s height, though without her big tits; she was more of an average size.
Karina nodded and took her wrap off, putting it next to Mary’s. “So, I don’t know. Everybody says it’s so great, but nobody can tell me why!”
Mary laughed. “Alright. Let’s start with what you’ve done already. Tell me exactly what you have done so far and with who? Guys? Girls? Both? Tell me everything! No judgments! Believe me, I have done it all!”
Karina smiled and nodded. “Okay.” She shrugged. “Nothing with guys, but I’ve seen stuff, simply because I have two brothers and a father. I’ve seen my parents ... uh, making love...”
“Fucking their brains out,” said Mary.
“ ... yeah, that, too. Anyway, I’ve never done anything with boys.”
“That implies you have done something with girls.”
Karina blushed. “Uh...” Mary raised an eyebrow, and the teen continued, “Yes, I’ve kissed a few girls, friends, to practice kissing.” Mary laughed and Karina said, “Well, how am I supposed to learn how to kiss!”
Mary laughed even louder. “Oh, God, that is funny! That’s how we all learn how to kiss! So did I and so did your mother! Trust me!”
“Oh. So, anyway, a few of us have done some practicing.”
“Practicing kissing or did things get a little more involved?”. When Karina gave a confused look, Mary asked, “Was there any touching or licking or playing?”
Karina nodded in understanding. “Yes, we did. Not all of us, but some of us. Janey, we were at her house once, and she had a vibrator, you know, and another time Makala didn’t just kiss me, but she also sucked my nipples.”
“Has anybody ever touched or kissed your pussy?”
The young girl blushed and simply nodded.
Mary grinned. “And did you like it?”
Karina blushed even more, but she quietly said, “Yes.”
“Good! Honesty is the way to deal with this sort of thing. Don’t worry. You know what this makes you?”
“What?”
“Normal!” She turned towards the patio door to the back yard. “We ready yet?”
“We can start!” responded Johan. Though it sounded impromptu, Mary and Johan were working off a script they had practiced ahead of time.
Mary got off her barstool and went to the refrigerator; Karina followed. “How can I help?”
Mary handed the girl a platter of hamburgers. “Take these out to Johan. There’s one each, but if you want a second, I can quickly thaw one out. We have some cole slaw and mac salad as well.”
Karina went out the patio door and found her host semi-naked, in that he had taken off his wrap but was now wearing a long apron. When she saw him, he said, “Trust me! You don’t want to get anything spattering on you without an apron.” Karina blushed and nodded. He took the plate of burgers and pointed her towards a picnic table. “We’ll set things up there and eat out here.”
“I’ll go help Mary.” Johan nodded and smiled. He turned back to the grill and put the burgers on.
Mary came out next, carrying some plates and silverware. “I put some stuff on the island; just grab it and bring it out.”
“Got it!”
Karina figured it out and brought a pair of platters out and Mary took them out of her hands. She joined Mary at the table, and they sat and talked while Johan cooked the burgers. Nothing sexual was discussed; instead they talked about school and the weather.
After dinner, things changed. Karina helped the Tannhausers bring in the dishes and only then noticed that Johan had stripped off his apron and was as naked as Karina and Mary. Johan sat down in an armchair, but Mary held her hand out to the teen. “Come with me. Let me show you our bedroom.” Karina followed though she glanced back at Johan, who stayed seated. Once in the bedroom, Mary said, “First things first. Do you need to use the bathroom? It’s right in there.” She pointed at the master bathroom. “It’s always important to clean up before anything sexual. I’m not saying you need a shower before kissing somebody but clean and fresh is always nice. If I want Johan to be clean, he probably wants the same for me.”
That made sense to Karina. She used the toilet and took extra care cleaning up afterwards. When she returned to the bedroom, she found that Mary had stripped the top sheet off the bed. “I don’t know about your parents, but while we often have sex in the living room, most of the time it’s in our bedroom.”
Karina nodded. “I think it’s the same for Mom and Dad, though I know Mom likes doing it out in the back yard or in the pool.”
“That can be fun. Anyway, in addition to the bed, we have some other fun stuff here.” She opened her nightstand and pulled some things out. “These are vibrators and dildos. Have you ever seen these sorts of things?”
“Katie has a vibrator, and she showed it to us once. She even turned it on and showed how it could go inside her pussy.” She blushed and grinned. “We all tried it after that.”
“There are all types and sizes. There are even remote-control models that you can put inside yourself and then your boyfriend can operate them by his macrolink.”
“Wow!”
Mary held up a small squeeze bottle. “This is lubricant. Sometimes you need some extra moisture to get ready. Guys need it, too.” Karina looked confused at that, and Mary explained, “When a guy is stroking his cock, sometimes he needs some lotion.” It was obvious the girl didn’t understand, so Mary called out, “Honey, you want to come in, please?”
Johan came into the bedroom. “Is it that time?” he asked. Karina noticed that Johan’s penis was hanging between his legs, still limp but slowly inflating.
“Basically. Let me clean some of this up first and then you need to get on the bed with us.” Mary tossed the sex toys back in her nightstand but left the squeeze bottle out. “Now you get on the bed between us.” She moved away from Karina, who also moved to make room for Johan.
Johan crawled in between them and twisted so that he was laying on his back. By then Karina noticed that his cock was fully erect, and though a few centimeters short of her father’s, it also looked a little thicker. Also, like her father, Johan’s cock and balls were shaved. He twisted his face and kissed his wife, and then he turned to face Karina. He kissed her on the forehead. “How can I help?” he asked, smiling.
“Karina wanted to see what lubricant was used for and I volunteered you.”
“Got it, I’m a volunteer for science.”
