The thought of watching his step-sister screw, excited
Justin. She was a cute girl, blonde with big blue eyes
and a cute smile. She had had sex before, and he always
wondered what it would be like watching her do it.

He had seen her naked a couple of times, and promptly
jacked off after each time. He and Scott both were
virgins, but it looked like Scotty was gonna get his
first. All the girls liked Scott. He had brown hair and
eyes and was a cross between Scott Baio and the Karate

So as they got ready for bed on the fateful night, he
watched as Scott stripped down to his shorts and lay on
the covers of the guest bed. He knew his step-sister
would be in shortly after the lights were out and he
had pretended to go to sleep as they had planned.
Scotty was a little startled when the girl got in bed
with him, but calmed as she said, “He’s asleep. No one
will know.”

She stroked the bulge in his shorts; she put her hand
beneath the elastic and grabbed his cock. She pulled
his shorts down to his knees and straddled him as he
lay on his back. Expertly, she placed his swollen prick
on the opening of her hole and settled onto it, feeling
in sink deeper into her cunt.

Scotty instinctively pumped as she moved up and down on
his rod. She was wearing only a long tee shirt with
nothing under it. As the two stroked, Justin watched,
stroking his own cock under the covers. Soon Janet was
on her back with her legs wide apart and through the
dim night light he watched the cheeks of his friend’s
ass gather dimples as he pumped his step-sister’s cunt.

Soon, with a groan of ecstasy, Scott shot his virgin
load deep into Janet’s cunt as she squirmed in orgasm.
Hot, sticky white cum was streaming down the crack of
her ass as they continued to pump, Janet shuddering in
orgasm and Scotty making obscene slurping noises as he
pumped the cum drenched pussy. After his step-sister
had gone back to her bedroom, Justin said to his friend
Scott, “Wow, man, that was great! I watched the whole

Scott replied “Too bad she’s your step-sister. I see
you are stroking your cock… I can imagine how horny
that must have make you. Let me help.” Scott came over
to Justin’s bed, still naked and his cock sticky with
cum. He pulled back the covers to reveal Justin’s hard
cock and looked his friend over, remarking how much he
looked like his step-sister.

He gently cupped his friend’s balls and with the other
hand stroked his smooth, round ass letting his finger
play around Justin’s asshole. “My cousin put it in my
ass once and it didn’t feel too bad… Since you set me
up with your step-sister, I’ll let you do it too.”

With that, Scotty lay on his back next to Justin and
spread his legs wide apart. With a hand on each cheek,
he opened his ass-hole to give the boy access. Justin
eagerly entered the ass that he watched a few minutes
before as it fucked his step-sister. Screwing Scotty
would be better than just jacking off.

As he sank his cock in Scott’s butt, he realized what
it was that got his step-sister all hot. Scotty was
cute. He pumped his friend faster now as he thought
about his step-sister and, not being able to hold back
anymore, dumped his load in hot gushes deep into
Scotty’s ass. As Scotty felt the blonde 18-year-old
release the cum inside him, he continued to stroke his
cock, releasing his load all over Justin’s belly.

The two boys lay side by side, their sexual urges
temporarily relieved, not realizing that Janet had
watched her step-brother screw his friend. She never
realized her brother was so horny or that his ass was
so cute… now she wanted him to fuck her too!

It was raining hard outside and Justin and Janet were
home from school for a holiday. 18-year-old Justin was
laying in bed stroking his cock thinking about how his
19-year-old slut step-sister had fucked his friend
right there in that room – on those sheets – there was
still dried cum on them where Scotty had filled her
hole to overflow. Suddenly, the room lit up and the
crashing sound of thunder closely followed. Janet came
running into the room and hopped under the covers with
her brother.

“I’m scared!” she said. “Shit!” thought Justin, who was
getting to the point of shooting his load before the
thunder came — he had wanted to finish jacking off.
His jockey shorts were still pulled down around his
hips and his cock was still erect, now resting against
the tee-shirt that Janet wore to bed. “Ohhhh! I think
my step-brother was jerking off,” reaching to feel his
stiff cock, she continued, “Yes… he was. Maybe his
step-sister can help him out!” She pulled down the

Justin lay on his back, his cute round ass pressed
against the sheets; his stiff cock was protruding from
a sparse patch of pubescent golden hair. Janet pulled
off her shirt to show her pretty, round developing
breasts. She squirmed out of her panties to reveal her
moist slit. Justin stared at her speechless as she said
“I guess that brothers and sisters are not supposed to
do it with each other, but you are so cute and I am so
horny. As long as you’re careful not to get me pregnant
I don’t see any harm.”

She straddled her brother and guided his stiff cock
into her moist slit. As she looked down at him,
smiling, she began her familiar fucking motion,
tightening the muscles of her pussy around his cock as
she moved up and down. Justin pumped in rhythmic
motion, holding on to the buns of his step-sister’s

“Oh! I want you! Fuck me! I’ll do anything you say. I’m
your whore,” moaned Janet as she continued to hump and

Janet shuddered in wave after wave of orgasm. “Oh,
Jan… I’m gonna squirt!” yelled Justin as he felt the
cum rushing from his balls. “No, wait!” said Janet
hurriedly as she got off of her brother, turned around,
and buried her face in his crotch.

Justin’s cock was pounding as she put in her mouth and
stroked in hard and fast. He released his load in
gushes — wave after wave of his hot white cum going
into his step-sister’s mouth… dripping down her chin
and back on to his belly.

Janet’s legs were spread in front of his face and as he
shot off, he fingered his step-sister’s hole. When he
had shot the last of his sperm into his step-sister’s
face, she turned and smiled, cum still dripping from
her chin. Let’s rest then do it some more!
