Coming of Age Sex Story: Chapter 5: We Grow Up - When I was fifteen, my father remarried after being a widower for several years. I suddenly found myself with two stepsisters, vivacious twins a year younger than I was, full of energy and curiosity. It took me a while to go from being an only child with one parent to being part of a busy family, but once I adjusted, I found that having stepsisters wasn’t a bad thing at all.

Our first Thanksgiving as a new family was a bit strange. After my mother died, my dad and I went to his parents’ home for our holiday dinners, not something that I looked forward to. My grandma Cecilia was a very religious, pious woman who rarely smiled, especially on holidays. My grandfather Carl was more fun to be around, but even he could get depressed by his wife’s attitude. This year, my dad told them he wanted to spend the holiday with his new bride and my stepsisters. Surprisingly, the old folks didn’t seem to mind. My father had two older siblings with children of their own, so it wasn’t like we would be missed.
The tournament the girls had been looking forward to started on the Friday after Thanksgiving and ran through Sunday. The Stars’ first game was early Friday morning, and the hotel they were staying in was a three-hour drive away, so we had our Thanksgiving dinner early, so Marge and the girls could get to the hotel before dark. I think the K’s were even more excited by the idea of spending three nights in a hotel with their teammates than they were in playing soccer against some very good teams.
My father and I stayed home. I was kind of looking forward to that. We hadn’t spent much time together since the wedding. We did some guy stuff while the women were gone - fishing on Friday, then a movie, ‘Raiders of the Lost Ark’, if I remember correctly, followed by a trip to my favorite bookstore on Saturday. When we got home, we were surprised to see Marge’s car in the garage. When we went inside, she told us that the girls had lost two of their three games, so their tournament was over by early afternoon on Saturday.
I found the girls in Katie’s room. I thought they would be disappointed, but they were their usual bubbly selves. Of course, I had to ask how the tournament had gone.
“It sucked,” Katie told me. “We won our first game, but Elsa got hurt in the second game, and our backup keeper isn’t very good, so we lost the next two games.”
“But we had fun in the hotel,” Kiley said.
“Elsa’s hurt? How bad is it?” I asked.
“It’s her ankle. We thought it might be broken, but it turned out to just be a bad sprain.”
“Is she home already? Should I call her?” I asked, looking at my sisters for advice.
“She’s home. They came back last night. Maybe you could call, but be ready for some tears. She’s really upset,” Katie said.
I thought the right thing to do was to call, as her sort of, maybe, boyfriend, but I wasn’t looking forward to it. I’m not exactly good at the whole empathy thing. Eventually, I worked up enough courage and called her. She told me all about her injury, how it happened (“That bitch rolled into me on purpose”), how much it hurt (“I’ve never had anything this bad happen to me”), and how mad she was (“Good thing that bitch is on a team we’ll probably never play again. I’m afraid I might go after her and get a red card”). I listened as she continued to complain, which I guess is one way of being empathetic.
“Are you on crutches?”
“Just for a few more days. That really sucks. Going back to school on Monday could be an adventure. Maybe some cute boys will want to help carry my books,” she giggled.
After that, it turned into one of our usual conversations, with lots of silly, teenage jokes and naughty, suggestive descriptions of what we might do the next time we got together. When we finished, it seemed like she was feeling better, so I figured I’d done a good thing. “Wish I could help you,” I said, as any good wannabe boyfriend would. “Can I come over and kiss it to make it better?”
I heard a long sigh from Elsa, then she said, “I wish. I kinda like the way you kiss me ... and not just my mouth.” Hearing that small, teasing compliment made my heart beat faster, and my cock swell slightly.
There were some momentous events for us after Christmas that year - at least they were momentous to me. On January 10, I turned 16, and two days later, my dad took me to the DMV to get my unrestricted driver’s license. That small, laminated document identified me as a proper teenager. All I needed was a car.
Marge let me drive her car occasionally, even though I could tell she was still a little uneasy about it. I think she was already dreading the day when my stepsisters became drivers. Much to my surprise, my dad took me car shopping one Saturday afternoon a few weeks later. It really wasn’t shopping; apparently, my dad had already found the car and haggled the details out with the dealer, so after I gave it a test drive, it was mine.
One of the first trips I made without adult supervision was to see Elsa. I was hoping to go by myself, but of course, the twins wanted to go too. I was still a little nervous about driving and didn’t need any distractions, so when we got in the car, I told my high-energy siblings they had to be quiet and that I wasn’t going to turn on the radio. Forcing them to be silent for more than five minutes seemed like a kind of punishment, and the scowls on their cute faces confirmed that, but they cooperated, and we had a mostly quiet ride.
They had told Elsa that we were coming, so she was waiting for us in her front yard. After I parked, Katie and Kiley seemed to release all the pent-up energy that they had been holding in while riding with their cranky stepbrother, because they jumped out of the car almost before I came to a full stop and ran toward Elsa. They wrapped their arms around her like they hadn’t seen her in years, not weeks, which made me a little jealous. I mean, after all, I was sure I was the one she really wanted to see.
When they let go of my Viking princess, it was my chance. It was the first time I’d seen her since before the disastrous tournament, and I wasn’t sure what to expect. The first thing I noticed was that she had cut her hair. The blond ponytail I used to enjoy watching whip from side to side as she ran was gone, replaced by a short style that I think was made popular by the skater Dorothy Hamill. Her hair barely covered her ears, and she had bangs. I started to tell her that she looked like a boy, but figured I would keep that comment to myself.
I wasn’t sure what to do. Part of me wanted to give her a big hug, maybe even dare a kiss, but standing in her front yard, with the twins right there, I decided it wasn’t the right time or place. When I looked up and saw Elsa’s mother watching from the front porch, I was glad I had resisted the urge. I settled for a fist-bump, which seemed kind of lame, but safe. I really wanted to make a good impression on Elsa’s parents, since I was hoping they would allow me to date their daughter.
Elsa took us inside and gave us a brief tour of her home. I think she might have been showing off a little, because it was a very nice place. Katie had told me that Elsa’s father was a dentist and her mother was the registrar at the local community college, and the house reflected their upper-middle-class position in life. The tour ended in Elsa’s room, which was probably as big as the K’s rooms together, with two walk-in closets, a large bathroom, and a king-sized bed. I couldn’t help thinking how beautiful Elsa would look lying in the middle of that big bed, her blond hair spread out on her many pillows as she slowly woke up in the morning, with me next to her, of course.
I guess I must have let my imagination run away with that image a little, because I heard Kiley whisper in my ear, “Earth to Ray, stop staring at her bed. You’re gettin’ creepy.” Luckily, Elsa was busy talking to Katie, and apparently hadn’t noticed me drooling over her bed.
Elsa’s mom peeked in and told us that she had fixed some snacks. The twins followed her out, but as I started to go, Elsa grabbed my arm and held me back. “No kiss?” she grinned.
Kiss? Hell, what I really wanted to do was throw her onto that big bed and roll around with her in an erotic wrestling match, but again, I had to control myself. She closed the door with her foot after the twins left, and we embraced, our mouths locked together like ... well, like horny teenagers. I wrapped my arms around her body and pulled her close to me. We knew we had only a few seconds before someone would notice we were missing, but we did as much as we could in that short time. My hands moved up and down her back, like I was trying to touch as much of her beautiful body as I could. We came up for air just as Katie opened the door and said, “You two better get out here. Elsa, your mom’s gettin’ suspicious.”
After we got back to the living room, we sat around, enjoying the sandwiches and chips and practicing our small talk, almost like we were adults. I turned on my charm, scant as it was, and started complimenting Elsa’s mom. I remember saying stupid things like “This is great, Mrs. Swenson”, and “You have a great home”, and other nauseating comments. I was trying to get her to like me so that if and when I asked Elsa out, at least her mother would be on my side. I even eagerly agreed to help her clean up our mess when we finished.
The twins tried to do their part to assure Mrs. Swenson that it would be safe to let her daughter go out with me. “Ray’s a good driver,” Kiley said. “He made us be quiet on the way over so he could concentrate.”
“And he’s been a great stepbrother, always ready to help us with our homework or anything else we need,” Katie added. I was beginning to feel like they were trying to nominate me for sainthood.
When it was time to go, Elsa followed us out to my car. After I got in, she tapped on the driver’s side window, and I rolled it down. She leaned in the open window and said, “So, you got your license, and you have a car. Are you ever gonna ask me out?”
“I’ll call you later. We’ve got an audience now.”
“We’re not an audience,” Kiley complained, “we’re family. Go ahead, ask her.”
“Elsa, would you like to go to a movie and get a pizza next weekend? You can pick the movie, and I’ll pick the pizza toppings.” I don’t know why I found it so difficult to say those few words, but my voice did crack a little.
She gave me a big smile and said, “I have to ask my parents, so I’ll get back to you.”
I was so happy that on our way back home, I turned the radio back on and let my sisters pick the station. I was sixteen, I had a car, and I was about to go on a real date with my Viking Princess. Things couldn’t be better, then they weren’t.
I waited a few days for Elsa to call, but then grew impatient and called her. I could tell from the start of the conversation that she didn’t have good news. First, she apologized for not calling, then, after stalling a bit, she finally admitted, “My parents say I can’t start dating until I’m sixteen.”
“Has that always been their rule?” I asked, wondering why she hadn’t let me know earlier.
“My dad has been teasing me about it for a long time, but you’re the first boy to ask me out, so I’d always hoped it was just a joke.”
“Well, I guess we just have to make do with phone calls instead,” I said, trying to cheer both of us up. “When will you turn sixteen?”
“In five months,” she said.
“Might as well be five years,” I moaned.
“I’ve got an idea. Are you alone?” she asked. When I explained how the shared phone system in our house worked, she said, “Good. I’ve got my own phone, and my parents usually don’t bother me when my bedroom door is closed, so let’s try something.”
“What?” I asked, hoping it was what I thought it might be.
She was quiet for a moment, then she said, “I’m lying here in my bed with a short nightie on. If you were here, standing at the foot of my bed, watching me, I think if I raised my knees a little, you could see the pink panties I’m wearing. How would that make you feel?”
She’d gone down the path I had been hoping for, and I was more than ready to play along. I got up and went to my door and locked it, then got back on my bed and told her, “I think that would make my dick swell up. If you were here, I’d be glad to show you. Can I get a look at your pussy now?”
“Well, I guess that’s all right.” She didn’t say anything else for a moment, and I wondered if I had gone too far. I was new to this naughty phone call game. Then she whispered, “Okay, panties off. I’m lying here, on my back, with my knees up and spread. You can see everything now, my pubic curls, my slit, and if I spread myself open, you can even see my vagina. It’s already getting damp just thinking about you. What are you doing? Got your cock out ... stroking it ... excited by what I’m showing you?”
“Oh god, yes,” I told her. It took me a moment to catch up with her imagination, but after I slid my boxer briefs off and started playing with myself, I grew bolder and harder. “I wish you were here, jacking me off.”
“Hmm, I’m already there. I’m holding it. God, you’re so hard. Do you feel my hand moving up and down now?”
“Geez, yes,” I told her. It took every bit of my imagination to fool my brain into thinking that the hand jerking me off was Elsa’s and not mine.
She was ready to move on. “Kiss my pussy now. I like how you do that.”
“Can I use a finger too?”
“I’m already doing that. Think you can find my clit again?”
I closed my eyes, trying to remember every moment from the night I had explored her private parts. “Lick, or suck?” I asked.
“Surprise me,” she said, her voice a husky growl.
The more we played, the more Elsa began to sound like a feral creature, and not the cute blond I was falling in love with. Hoping to come up with something that would actually surprise her, I said, “No, what I want is to put my tongue as deep inside you as I can. I want to taste your... “ I paused, trying to remember the word, then came up with it, “ ... your secretions. Open yourself up for me.”
“Damn, Ray, you’re really getting nasty. Okay, I’m spreading my pussy lips for you, so let me feel your tongue pushing inside me.”
She was right; the further our adventure continued, the wilder my thoughts became. “My first try must have been off target,” I told her, “it tasted like pee.”
Elsa giggled and said, “That’s only fair. Don’t forget, you pee out of the same place as your baby stuff comes out, and I was willing to put it in my mouth, so be a man. Now, try again, and tell me what I taste like.”
It was getting harder and harder to find the words to describe the images in my mind, but I tried. “Ah, that’s better ... kinda tart and sticky.”
She laughed. “Sticky’s not a taste.”
“Well, it’s all over my face now. I think I got the tip of my tongue inside, but it’s hard to tell.”
“Oh yeah, you did. It tickles, but feels great too. I’m getting close to cumming. You?”
I wondered what she was doing to simulate the sensation of my tongue poking into her vagina, but I was afraid to ask, fearing it might break the spell. Stay in character, I reminded myself. “I’m close too. Can I cum on your boobs?” I didn’t even know where that idea came from, but it was out there now.
“Eww,” Elsa groaned. “Okay, if you want to, just not on my face.”
We both got ourselves off at almost the same time, with lots of moans and groans expressing our climaxes. I heard Elsa panting in her bedroom, then she said, “That was amazing. I guess if we can’t date, we’ve at least got this. Do you want to try this again?”
“Oh yeah,” I told her. “Over and over, for the next five months.”
It took a while for us to hook up again. We finally found time late on a Saturday night. When we started, Elsa was definitely ready to go. “I’m already naked. You?” she said.
I had been slowly stroking myself before I called, but when she said that, my erection went into full-attack mode. It only took me a second or so to take off my clothes. It was kind of a chilly night, so I cheated a little by getting under my blanket.
“Hard yet?” my horny, almost-girfriend asked.
“Oh yeah. I think rock hard is the expression. Are you turned on?”
She giggled and said, “Uh-huh, I started before you called. Wanna know what I’m using?”
“Not your fingers?”
“Usually that’s enough, but I wanted something more realistic tonight, so I’m using the handle of my hairbrush. It’s shaped like a dick, a big one. I bought it just because of the way it was shaped.”
“Done that before?” I asked.
“A couple times. I use a little Vaseline on it to make it go in easier. I’ve got it in now, but only just the end.”
If I hadn’t been totally erect before, I certainly was after she told me that. “So, does that mean I can fuck you tonight?”
“That’s the idea,” she told me. “I’m lying here on my back, with my legs spread wide. Get on me and go for it.”
“Okay, I’m on my knees, leaning forward a little. I’m using two fingers on my right hand to spread your pussy open while I use my left to aim my cock at your opening. It feels like I’m partially in, so I’m pushing forward now.”
“Good, Ray, just take it slowly. I can feel you opening me up, stretching my tunnel more now. Is it all in? It feels like it.”
I was picturing her pushing the brush handle into herself as I moved my hand faster. It looked like this was going to be a quick fantasy this time. “Yeah, I’m all the way in. Can you feel my body against your thighs?”
“Come on, Ray, fuck me now. Move it in and out faster. I can take it.” I could hear Elsa panting now, a clue that she was working her hairbrush dildo hard.
My own orgasm was rapidly approaching. Neither one of us was saying anything now, caught up in our own thoughts. I was just about to cum when I heard a knock on my door.
It was Kiley. “Ray, if you’re not asleep, I need the phone. I forgot I was supposed to call Petra tonight.” As badly as I wanted to continue our fantasy, I couldn’t just tell my stepsister to go away. That wasn’t how our shared phone deal worked.
“What’s going on?” Elsa asked.
“Kiley needs to use the phone. I have to give it to her, or she’ll be pissed.”
Elsa laughed. “That’s okay. I got myself off anyway. Thanks for fucking me.”
I put my boxers back on and tried to get my erection to subside, but my dick was still an obvious lump in my boxers when I opened the door. I tried to stand partly behind it as I handed the phone to my sister.
“Why are you hiding?” she asked. “Were you jackin’ off while you were talking to your girlfriend? That’s kinda pervy, but as long as she doesn’t mind, I shouldn’t either.” I expected some teasing from Kiley the next day, but she never mentioned it.
I expected to continue our phone sex play often, but after that second night, I didn’t hear from Elsa for several days. When I called her, it went to her voicemail. Something strange was going on, but I had no idea what. I wondered if Elsa had done something that caused her parents to take away her phone. Unfortunately, that wasn’t it.
When Elsa called after ghosting me for a couple of weeks, I could tell by the sound of her voice that she didn’t have good news. Let’s just say that it was a short, soul-crushing conversation that left me stunned and almost in tears.
I took the phone back and put it on the kitchen counter, where it stayed when no one was using it. Katie and Kiley were watching TV in the living room, but I didn’t look at them or say anything; I just trudged back to my room and plopped down on my bed. I pulled a pillow over my head and hoped the world would go away.
I should have known that my unusual behavior would attract the attention of the twins, and it wasn’t long before they were in my room, standing over me. “What’s going on?” Katie asked.
Kiley grabbed the pillow that I was trying to hide under and threw it on the floor. “Tell us,” she said, “remember, we’re family now, and families don’t have secrets and always help each other.”
I knew they only wanted to help, but I was a little embarrassed to tell them what had just happened. “Well,” I said, trying to keep my voice from cracking, “if we had really been dating, I would say that Elsa broke up with me, but since we’ve never gone out, I don’t know what to call it. Anyway, she told me to stop calling her, but she was nice about it.”
“What happened? What did you say to her?” Katie asked, like she knew it had to be my fault.
“What did you do?” Kiley added.
“Nothing,” I told them. “It wasn’t me, it’s her. She said she has a boyfriend now, and he’s asked her to go steady, so she doesn’t feel right talking to me anymore. The thing I don’t understand is how she can be going steady with someone if she’s not even allowed to date. I think she’s been seeing that guy and lied to me about not being able to date until she was sixteen. That just rubs salt in the wound.”
“I’ll kill her,” Katie pledged.
“Or scratch her eyes out,” Kiley added.
