Chapter 2: Getting to Know My New Sisters
Coming of Age Sex Story: Chapter 2: Getting to Know My New Sisters - 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.

I wasn’t sure what to expect when I woke up after my adventurous evening with Kiley. I wasn’t looking forward to any awkward conversations with her, and I had no idea what she might have told her sister. As it turned out, it was a normal Saturday morning for our newly blended family.
Both of my new stepsisters played soccer, and that was the usual focus on Saturdays. Dad had encouraged me to go to their games as a way of getting to know them better. It helped that they were on the same team; it saved us from having to run from one game to another, but it must have been confusing for the coach, who had trouble telling them apart and usually just called them “twiners.”
My favorite part of watching their games was when the girls finished warming up and quickly ran over to the sidelines to switch from their warm-up jerseys to their game shirts. It was only a few seconds, but even that brief glimpse of all those nymphets in their sports bras made it a worthwhile day. I wasn’t the only one who didn’t do the polite thing and look away. I saw a few leering dads watching them change, too.
Other than the K’s, the player I was the most interested in on the Shooting Stars, their team name, was Elsa Swenson, the tall, blonde goalkeeper. I hadn’t met anyone named Elsa before, so like the nerd I am, I did some research and found out that Elsa was a Swedish name, and she looked the part, with her long, blonde ponytail that swished back and forth when she ran, like a ... well, pony’s tail. It made me feel good when she smiled and waved at me when we showed up for the game that Saturday. Damn, she knew who I was and seemed to like me! It was close to a miracle. Katie saw it too and encouraged me to call her. She even gave me her number, but as usual, when it came to girls, I was too insecure to make the effort. I’d pretty much given up on having a girlfriend until I was in college, which is why I had been interested in things like “Lollipop Cuties.” My girlfriends had existed only on the pages of those magazines, but now, I was living in the same house as actual young girls, and sex with them wasn’t just a fantasy. Now, Elsa was interested in me too. What more could I wish for?
As I watched Elsa warming up that Saturday, I tried not to stare, but I couldn’t help wondering what her hands would feel like on my cock instead of Kiley’s. They were obviously bigger, and I assumed her skin might be a little rougher, even though she wore keeper gloves. Unlike most of the girls on the team, she had noticeable swellings under her shirt. She had fuller, more athletic thighs than my skinny sisters, and I couldn’t help imagining what it would feel like if I ever got the chance to run my hands up from her knees into the leg hole of her soccer shorts. Okay, I admit it, even at fifteen I was already well on my way to being a perv, a condition I’ve never overcome. I paid so much attention to her during the game that when it ended, I had to take a few moments to let my erection subside a bit before I could get up without embarrassing myself.
As we headed to the parking lot, I saw Marge standing by her Ford Explorer, dangling her keys toward me and grinning. “Take us home, Ray. You need the practice.”
I got my learner’s permit as soon as I turned fifteen, but I hadn’t had much time to practice. The only vehicle we had was Dad’s pickup truck, and since he was a self-employed carpenter, it was essential to his work, which only added to the stress when I did get a chance to drive. The only times he took me out for a driving lesson were on Sunday mornings, in an empty mall parking lot. If I didn’t crunch the gears too much, he might even let me drive home. I knew it was doubly hard for him because of what had happened to Mom. He tried not to freak out, but our drives were often punctuated with multiple warnings: “Watch that car ... use your turn signals ... brake sooner...” and so on. By the time we got home, we were both worn out.
When Marge saw what was going on, she started letting me drive her SUV. Driving with Marge next to me was just what I needed to build up my confidence. I was getting more and more relaxed each time I drove with her, but this time was different; I was going to have Katie and Kiley as passengers, and that was terrifying. I was just glad that my father was working that day. Even an SUV has room for only a few backseat drivers.
As I opened the door and slid behind the wheel, I glanced over and saw Elsa watching me, with a big smile on her beautiful face. It was another four months before I could get my real license and hopefully start dating, but at least now I knew who the first girl I would ask out would be. I totally ignored details like whether she even wanted to go out with me or whether her parents would let her date a boy they didn’t know, who had just gotten his license. And could I actually muster up enough courage to call her? In the meantime, I had my naughty stepsisters to keep me company.
Thursday night, our parents went out to dinner with friends, leaving the three of us home alone. Katie and Kiley made hamburgers and fries, and I cleaned up the kitchen. We settled down in the living room to watch TV. We had small TVs in our rooms, but watching shows together on the living room’s big screen was fun when we could agree on what to watch. We piled onto the big sofa in front of the TV, Katie leaning back on one end cushion, Kiley at the other end, with me in the middle, with their feet resting on my lap. At first, it was a unique kind of thrill as they moved their bare feet around, getting comfortable, but when a territorial battle over who got access to my lap broke out and turned into a kicking contest, I knew my balls were in danger, so I played my big brother card and broke it up.
We watched a couple of forgettable sitcoms, common in the mid-80’s, then the girls got up and headed down the hall without saying anything to me. I watched as they went into Katie’s room and closed the door. I knew something was up. The two of them, together, being quiet, was unusual.
There wasn’t anything else worth watching, so I decided to do some homework. At least that’s what I told myself. Actually, I was being nosy. I should have respected my sister’s privacy, but after the strange way the girls had been acting that evening, exchanging glances and smiles at dinner, and not saying anything to me, followed by their apparent planned decision to go to Katie’s room and close the door, had roused my suspicion. On my way down the hall, I paused outside Katie’s door and leaned against it, just to see if I could hear anything. And boy, did I.
The first thing I heard was Kiley asking her sister, “So, are you ever giving these back to Ray?” At least now I knew what they were doing, and it was just what I had suspected.
“Yeah, in a couple days,” Katie told her. “But you wanna look at ‘em first, right?”
“You bet. All I’ve seen so far are the covers, which are pretty fuckin’ amazing.
I’d heard all I needed, but I couldn’t bring myself to stop eavesdropping. I heard them turning pages and making brief comments every few seconds; “geez,” and “wow”, and “that’s impossible” are a few I remember, then I heard Kiley gasp and say, “Damn, I didn’t know dicks got that big.”
“Remember, these guys are professionals, and they have to be hung like a donkey. It’s part of the job,” Katie replied, as if she knew anything about producing porn or donkey dicks. “I mean, look at their bodies, all muscled up and stuff. That’s not normal.” Katie giggled, then asked, “Is Ray’s thing that big?”
“Nah,” Kiley told her, “but remember, he’s just a teenager. I think his dick is the perfect size for somebody his age. It’s kinda pretty too, nice shape, smooth skin, at least when he’s hard.”
I don’t think any guy likes hearing his genitalia described as “pretty”. Manly, powerful, maybe even godlike, but not pretty. I suppressed my unease at Kiley’s choice of words and went back to eavesdropping.
“I wouldn’t mind havin’ him as my first, if he wasn’t our brother ... you know, that whole incest thing,” Kiley said.
“Is it really incest if he’s our stepbrother?” Katie replied. “I thought that meant we couldn’t have sex with him if we were blood relatives.” Damn, both girls were thinking about having sex with me now? Or was that just a theoretical question?
“It might be awkward, having him pop your cherry, related or not,” Kiley said. “You might start havin’ feelings for him.”
“Yeah, if that happened, you might be jealous,” Katie replied, and both girls giggled.
“Maybe we could get him to do us both,” Kiley said.
I thought my heart was going to leap out of my chest, and I was sure they could hear it beating. Then I heard them laughing and knew it was just some kind of twin joke. They did that a lot.
I hesitated, almost wanting to open the door, burst in, and claim my property, but instead I kept listening. I heard more pages turning, but now they weren’t saying anything, until they saw something that surprised both of them. “Geez, is he puttin’ that thing in her ass?” Kiley asked.
“Yeah,” Katie laughed, “There are a lot of pictures of stuff like that in the other magazine. I guess guys must like it. I’m not sure how he gets it in there, unless she has an asshole the size of the Grand Canyon. You think you could ever do that?”
“Hell no,” Katie declared. “I don’t even want a dick that big in my pussy.”
I couldn’t wait any longer. I knew it was probably a mistake, but I opened Katie’s door and peeked inside. “Hey, have you guys seen my calcula ... oh, shit, sorry.” Yeah, it was a lame excuse for barging in, but they seemed to buy it.
Katie shoved the magazine with the big dick guys under her pillow and shouted, “Don’t you knock? Get out of here!”
“Oh, so when you girls come into my room and take my stuff, that’s okay, but me coming into your room without knocking is different ... how?”
“He’s got a point,” Kiley said.
Katie sighed. “Okay, come on in and join the party.” She reached under her pillow and pulled the magazine out. “Maybe you can help us figure out what’s going on in some of these pictures.”
The girls scooted apart, making room for me to settle down on the bed between them. The three of us leaned back against Katie’s headboard as I raised my knees and propped up the naughty publication. I’d spent enough time over the last few weeks perusing its contents to know what was in it. The ‘articles’ consisted of a series of pictures showing a couple or a threesome meeting somewhere, then ending up in a bedroom, or in one case, in a forest. The text was in a language that I didn’t understand, but that didn’t matter. It was easy to follow the ‘story’ from the pictures.
Katie leafed through the first series, which showed a couple meeting up in a bar, then walking down a European-looking street, and ending up in a bedroom or hotel room. That’s when Katie asked the first question. “Do you think she’s a hooker?”
I couldn’t help letting my wiseass nature loose. “Nah, she looks like a schoolteacher getting ready to tutor that guy.”
“Yeah, like you tutored Kiley,” Katie laughed. So, the twins did share almost everything, a good thing to know.
Kiley apparently wanted to move on, so she ignored her sister’s joke. She turned a couple more pages until we came to some pictures of the woman performing fellatio. “I couldn’t do that,” she said, even though nobody had asked. “I mean, I gag every time I go to the doctor, and he puts that wooden stick in my mouth.”
“Me too,” Katie added, “but I did try to see how much I could do with the banana challenge at Jenna’s birthday sleepover last year. You remember that?”
“Oh yeah. It was Jenna’s idea, right? She was going to give whoever could take the most of it in their mouth a prize. I didn’t even try. I knew better.”
Katie laughed, “I wish I hadn’t. It was a terrible idea. I gagged myself, but I wasn’t as bad as what Gloria did.”
