Chapter 3: The Car Wash, and Other Interesting Events

Coming of Age Sex Story: Chapter 3: The Car Wash, and Other Interesting Events - 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.

The red digits of the clock radio beside my bed were practically shouting “9:30” at me, a ridiculously early time for me to be up on a Sunday. I heard a lot of activity outside my door and knew the rest of my family was busy getting ready for the big day. Apparently, this car wash thing was a bigger deal than I had thought. The K’s were bouncing back and forth between their rooms, discussing what to wear. It didn’t seem like a hard decision, just pick something you don’t mind getting wet, but I wasn’t a teenage girl.

My dad and new mom were in the kitchen fixing breakfast and preparing snacks for the day ahead. As usual, Dad was listening to a 60’s rock station. Normally, that’s not a problem. I was kind of a Beatles/Stones fan anyway, but that morning my leather-lunged father insisted on singing along to his favorite songs. The station was having a Rolling Stones tribute that morning, which really gets my dad cranked up.

“Hey kiddo,” he said, smiling at me, “thought you were gonna sleep all day.”

“Geez, Dad, it’s only 9:30.”

“And we’re leaving soon,” Marge added. “We’ve got to get set up before noon. We want to catch as many people as we can after church.”

“When everybody is feeling charitable,” Dad said, grinning like he had just figured that out.

After a normal Sunday morning breakfast of eggs, bacon, and toast, the girls ran back to their room, returning a few moments later with what they had decided to wear, matching (of course) white t-shirts and blue shorts, with red bands around their heads. I’d never seen them do that before, and Kiley explained, “It’s to keep our curls out of the water.” I have to admit they did look kind of cute in those red, white, and blue outfits, and being the young perv that I was, I took a moment to imagine how many of the girls would be wearing white shirts, and what might be revealed when they got wet.


I had assumed the car wash would be in somebody’s driveway or front yard, but as we piled into Marge’s SUV, she told me it would be in a Walmart parking lot. “We found out last year that they let groups like us hold car washes there, and they even match all the money we make.”

Like the ever-practical accountant I would eventually grow up to be, I asked, “Why would they do that?”

“Just being a good part of the community, I guess,” Marge explained.

It looked like most of the team was there by the time we arrived. A few of the parents were setting up tents, while others were hooking up hoses. Everyone else was standing around talking, like troops waiting to be told when to go into battle. Katie and Kiley headed for some of their friends, leaving me alone to wander around, which was what I wanted. I was hoping that I could spot Elsa and “accidentally” run into her.

It didn’t take me long to find her. Elsa was in the middle of a group of players. She was the tallest player on the team, and coupled with her long blonde hair, in thick braids that day, she looked like a Viking warrior. I didn’t want to seem too eager, so I slowly meandered in her direction, trying not to make eye contact or seem too desperate. Yeah, I was being anything but cool.

My demented mind had hoped to see a dozen or so young girls frolicking around in two-part swimwear, if not actual bikinis, but most of the girls were wearing their usual t-shirts and shorts, like my sisters. The only two girls wearing bathing suits were Elsa and the team’s smallest player, a munchkin named Jenny, who wore a red one-piece suit that would probably have been acceptable at a Mormon church outing. Her skinny body barely filled the spandex. When she turned her back, I could see hints of tiny butt cheeks being displayed. I almost felt bad that her little-girl features slightly stimulated me.

When I finally managed to make eye contact with Elsa, she smiled and waved. Okay, signal sent and received. I walked over, trying very hard to maintain eye contact and not stare at all the Swedish girl-flesh she was displaying. Soccer uniforms, especially the ones keepers wear, aren’t exactly revealing, so I had only been able to get brief glimpses of her natural beauty. Now I could see her powerful legs all the way up to where her pale skin disappeared into the bottom part of her suit. She had tan lines on the top half of her legs, so it didn’t look like she spent a lot of time wearing a bathing suit.

Then I noticed her breasts. Okay, drum roll please - they were spectacular. Nothing outrageous, like the models in my girlie mags, but still, compared to other girls her age, more than enough to fill the top part of her two-piece. I’d guessed that her boobs were nice from what I could see under her baggy soccer shirts, but now, there they were, on display for me to ogle, which I tried very hard not to do. Her arms, from the shoulders down, had a nice, soccer-girl tan, like the lower part of her legs, but the rest of her body looked more like the Scandinavian princess she was. Her midriff was bare, giving me a view of her stomach and navel, when I was daring enough to take a peek. It’s strange what simple things can turn a teenage boy on, and I found myself fascinated with her innie.


Since this wasn’t their first fundraiser, the team had the procedure down to assembly-line-like efficiency. The coaches got everyone together and started giving out assignments. Elsa volunteered to be a ‘washer’, whatever that was, and asked me if I wanted to work with her. That was probably the easiest exam question I’d had in a long time.

Once we started getting customers, I figured out the routine. Some of the girls sprayed the cars as they rolled to a stop under one of the tents. Another group, including Elsa and me, started washing the cars with soapy water and sponges. So, that was washer duty. Next, the hose-girls, and yes, there were lots of stupid jokes about calling them that, started rinsing the soap off. Then the driver would pull forward, where an army of girls, and a few parents, would dry them off (the cars, not the drivers). Kiley and Katie were ‘dryers’, which turned out to be a tough job when the afternoon sun started beaming down on them. I began to see Elsa’s wisdom in choosing to work under the tent, and occasionally getting sprayed with cool water.

After the first half-dozen or so cars went through, we were all getting wet, and it wasn’t long before the girls started taking their damp t-shirts off. That’s what I had been waiting for. I found myself in the middle of a covey (the right word?) of half-naked teenybobbers. Okay, half-naked is an exaggeration; they still had their sports bras on, but still, I could see that some of the parents were getting uncomfortable.

There was a lull in the middle of the afternoon, and that’s when Elsa had an idea. “How brave are you, Ray?” she asked, as we grabbed some lunch.

“I don’t know. Average, I guess.”

“So, if I asked you to do something a little crazy with me, no problem?”

I’d follow you anywhere, I was tempted to say, but it seemed a little corny. “Sure. What is it?”

“I think we need to attract more attention. Take your shirt off and come with me.”

At fifteen, I wasn’t ashamed of my body, but I wasn’t one of those guys who worked out a lot and liked to run around shirtless, showing off my body either. But Elsa had asked, and my shirt was still damp, so I took it off, put it on the ground next to hers to dry, and followed her as she headed out to the curb in front of the store. Two of her teammates were waving signs at the passing cars, and they looked tired.

Elsa talked to them for a moment, and they gratefully handed the posters to us. Elsa took the larger of the two signs and held it up against her body. In her two-piece swimwear, she almost looked naked behind the large poster. I saw several men, old and young, who ogled her when the light turned red, and they had time to take a good, long look. A few of them pulled into the parking lot and headed for our tents, so Elsa’s naughty plan seemed to be working. Elsa also got lots of lewd comments, which she didn’t seem to mind.

My sign was smaller, but with just shorts on, I was able to pull off the illusion of nakedness, too. I don’t know if I managed to attract any business, but I think a couple of older women did honk their horns at me.

When some of the parents saw what we were doing and came over to shut down our little show, we didn’t mind, because things were winding down anyway. Elsa and I went back to where the rest of the crew were putting things away and cleaning up. Our shirts were dry now, and when I put mine on, I knew from the sting on my skin that I’d probably spent too much time in the sun with it off. Elsa looked kind of red, too.

“I’m gonna be hurting tonight,” she said.

“Me too, I’m afraid,” I told her. I didn’t mind; being branded would probably have been acceptable for the privilege of spending time with the half-naked Swedish princess.

Elsa looked around, and when she didn’t see anybody paying attention to us, she took my hand and led me behind the area where our tents had been set up. There was a large trailer parked farther back, close to the loading docks. After taking another look around, Elsa stepped behind it, still holding my hand. As soon as we were out of sight, she stopped, wrapped her arms around me, and kissed me. It wasn’t anything as innocent as the kiss Katie and I had shared. Nope, this one I felt all the way to my toes, and other body parts too.

“I just wanted to thank you for being brave enough to go out there with me. It was fun.”

“It was,” I told her, “and I like how you say thanks.”

“I just wish we were old enough to be driving,” she sighed. “I think going to a drive-in movie with you would be fun.”

“We could ride our bikes,” I kidded.

“Bikes don’t have backseats,” Elsa said, with a sly grin.

I hadn’t even realized that during our kiss, I had wrapped my arms around her and was holding her body against mine. If you’ve been with me so far, you can probably guess how my body reacted. Elsa felt it and rubbed her pelvis against my erection. I couldn’t believe we were doing that in a Walmart parking lot, but we were brought back to reality when an older couple walked by and yelled, “Get a room”.

“We’d better get back,” I told her.

“Give me a call,” Elsa said.

This time, I was sure I would.


On the ride home, everyone was talking about how successful the event had been. “We made almost twice as much as last year,” Marge said.

“Yeah, maybe that’s because all of the girls are bigger now,” Katie said. “The guys pay more attention to us. One guy actually asked Penny out, and he was really disappointed when she told him she was fourteen.”

“I saw a lot of men in their twenties and thirties who seemed to be more interested in girlwatching than getting their car washed,” Kiley said, “especially after we took off our shirts.”

“I didn’t care for that,” my dad said. “That seems like a ... I don’t know ... kind of an odd way to make money, having girls running around in bras.”

“Oh, Travis, you’re just not used to being around young girls,” Marge told him. “Whatever works, right girls? And Ray, you did a great job today.”

“Especially you and Elsa’s striptease routine,” Katie laughed. “I hope you didn’t get too much of a sunburn.”

“What’re you talking about?” Dad asked. Apparently, while Elsa and I had been embarrassing ourselves, he had been busy talking football with some of the other dads.

“I’ll tell you about it later,” Marge said, patting him on the arm, a gesture I had noticed she used often. I saw the girls exchange a glance, and Kiley made a finger-in-the-fist motion. I’d heard the girls talking about how often they thought Travis and Marge were getting it on. They thought it was great, but I still found it hard to think of my dad having sex with my new stepmom.

After we got home, everybody took a shower and put on some nice clothes. Our parents took us out to dinner, not fast food, to celebrate the successful fundraiser. By the time we got home, everybody was too tired, and our bellies were too full to do anything but go to bed.


I didn’t usually go to the girls’ practices, and they didn’t have a game the following Saturday, so ten days or so passed without me seeing Elsa. I called her a couple of times, and we had long conversations, which only made my frustration at not seeing her grow. I said something about it to Katie one day, and that night she and Kiley both came into my room just as I was about to turn off my light.

They didn’t say anything, just crawled onto my bed and sat next to me, Katie on my right, and Kiley on the left. They weren’t smiling or giggling, which made it weird. It felt like I was about to be interrogated, and I wondered what I had done.

“I saw you and Elsa,” Katie said, with a bad cop scowl.
