Subject: Stepsister in Swimsuit

This story is fictional, but I'm sure someone out there has had a similar
experience! This is a story about a stepbrother and stepsister exploring
each other for the first time.

I was on my local pool's swim team in my teen years. I had figured out
that I was bisexual early in life and absolutely loved it when we had
swim meets so I could look at all the boys' bulges in their speedos and
all the girls' breasts and pussies through their one piece swimsuits. Our
team swimsuits were a plain blue colour, made of very thin material and
relatively tight. I think I must have done more staring at my fellow
swimmers than actual swimming!

When I first joined the team at 12 years of age, I became really close
with this boy named Matt. He was a skinny kid with short, spiky blonde
hair and shared my affection for swimwear. After I learnt about
masturbation from the Internet, I decided to have some fun with Matt.
During our next swim meet, when we had finished training, I asked him
whether he had heard of masturbating- he shook his head.

I told him to wait until the other guys were out of the change rooms.
When this had happened, I took Matt into a shower stall (we were still in
our speedos) and proceeded to rub his penis through his speedo. His
little penis grew hard until it reached its maximum 4 inches. I squatted
on the shower stall floor and pulled his swim briefs down, revealing a
very cute looking, thin, hard penis. It was smooth and completely
hairless.

I stroked his penis slowly at first, then moved faster. He told me he had
to pee and I said that the feeling was normal and not to worry. Before
long, I gave Matt his first dry orgasm and he did the same thing to me-
only I managed a few spots of cum. Unfortunately Matt moved town a few
weeks later so I only got to jack him off a few more times.

Anyway, the swim meets ran for two hours and most of the parents just
dropped their kids off and came back to pick them up at the end of our
session. There were a few parents who stayed inside the pool for the
whole two hours though. One of them was my mum, and another was the
father of a girl named Caitlyn who was one of the best swimmers on the
girls' team. Both of our parents had been single but were now dating each
other. Our families visited each other often and we became quite close.
At this point they were still a year away from marrying each other, so me
and Caitlyn weren't step siblings yet.

The boys and girls trained separately so I didn't see much of Caitlyn
during our swim meet until after everyone had finished changing and got
ready to go home. Our parents had become really close- me and Caitlyn
started sleeping over at each others' houses. On the car ride back to my
place, my mum told me that she and Caitlyn's dad would be spending the
night at a hotel in the city a few hours' drive from our country town and
would not be back until the next day. She told us to take care of each
other and not to sleep too late. Caitlyn and I both said we understood
and resumed our tickling fight in the back seat (I guess we were still
fairly childish despite being 15 and 13).

I should probably tell you about our appearance now. I was tall, had a
slightly muscular build and a mop of straight, dark black hair. I would
say I'm more cute than hot, but I'm definitely not totally good looking.
Caitlyn was tall for her age and had light blonde hair that ran just past
her shoulders. She was skinny but not stick-thin and had a nice pretty
face- not supermodel-looking but more of a girl-next-door from a teen
movie look.

Back to the story, our parents had left for the night and both Caitlyn
and I were using our laptops in my room. Eventually, we began to feel
tired so we said goodnight to each other and began to sleep (there were
two twin beds in my room). I tried to get to sleep but all I could think
about was the sexiness of all the great bodies in tight swimsuits I had
seen today. I decided it was time for a wank to help me sleep, so I went
to the bathroom, sat on the toilet and slowly began to stroke my penis up
and down. I was almost about to shoot when I heard the door creak open
slightly and stopped. Caitlyn came in and I tried to hide my boner but
she had already seen it.

'Wow, that looks so cool! Can I see it?' she asked. I was slightly
embarrassed but managed to nod. Caitlyn told me that she had always
wanted to see what a boy's doodle looked like. Mine wasn't very big
(about 4 1/2 inches) but Caitlyn was still intently interested in it. I
decided to ask her if she knew that boys could play with their penis and
make white gooey stuff shoot out. She said that she had researched a bit
(Caitlyn's a bit of a geek and loves to read books and learn more about
stuff) but wasn't quite sure how it worked. I told her I would show her
if she let me do something to her first. She agreed and I asked her to
put on her blue team swimsuit and sit on her bed.

She sat upright on the edge of the bed with her legs stretched out in a V
shape. I had stripped naked and put on my speedos as well (swimsuits make
me extra horny), and I sat directly behind her, with my boner touching
her back and my legs close to hers, dangling of the bed. I began to
gently rub her breasts with my left hand (inside her swimsuit) while
slowly swiping at her crotch (outside her swimsuit) with my right. After
a minute, she began to say 'oh, oh, oh', and then after another minute it
was 'OH, OH, OH', and after that it was 'OHHHHHHHH!' as her whole body
shivered and contracted and she began to shoot small bursts of cum from
her pussy onto her swimsuit to form a large wet patch on the crotch area
of the suit. 'Guess well have to wash that out' she joked and gave me a
quick peck on the cheek. 'Now it's your turn!' she said eagerly.

I happily obliged, sat on the carpet and pulled my speedos to my knees. I
asked Caitlyn to stand over me so that her wet swimsuit patch would be in
front of my face and I would be able to smell and lick it while I pumped
my little rocket. As I began to smell and lick her wet patch, it felt so
good and I thought I would pass out before I even came! Caitlyn began to
grind her pussy into my face and I was getting so aroused, I didn't
notice that she was beginning to undo her shoulder straps. I could feel
my orgasm coming closer and to my complete surprise, Caitlyn had dropped
her one-piece and it was now on my legs between my penis and my speedos.
For a few seconds I glimpsed heaven- well it was actually a 13 year old
girl's smooth, almost hairless pussy, nice and tight and beautiful. IT
WAS HEAVEN, OK?

I felt the strongest ejaculation of my life as rope after rope of cum hit
my stomach, Caitlyn's legs and even her cute little butt! I fell back on
the carpet as a naked Caitlyn- her swimsuit around her ankles- fell on
me. We just gazed at each other and kept like that for minutes.
Eventually, we cleaned up and hopped back into our beds. In the dim
moonlight, I looked over at her smiling face and grinned myself. I just
couldn't wait until next time.
