Emma shot Alex, her brother, for the fourth time in a row on
the video game they were playing. He sighed.
"How are you so good at this?"
She shot him again. "Because I'm me, I'm perfect."
Those words stayed with Alex.
The word 'perfect' triggered some sort of reminder, and he
started looking his little sister up and down. Since he was
13, he remembered feeling sexual attractions for his sister.
Now that he was 17, and she was 13, those hormones had caused
him to become horny even at the thought of her.
Some days he would peer into her bedroom to watch his little
sister playing with her toys or sleeping peacefully. More
recently he'd started masturbating over thoughts of her. He
wasn't a pedophile, it's just that he'd been with his sister
for so long and been attracted to her all his life that he
was still frustrated that he couldn't say anything.
Today, he felt that he needed to do something. His parents
were out at a meeting and it was late at night. Casually, he
dropped in a sentence.
"Do you know what sex is, yet?" he asked.
Emma looked at him, mouth open. "Of course I do! Stop trying
to distract me!" She shot him once again.
"Have you ever had sex?" Alex smirked, staring into Emma's
blue eyes that were staring at the screen.
"None of your fucking business!"
"Oh, okay, I thought you had. Obviously not."
Emma smacked him playfully on the arm. "Well then you'd be
fucking right. I'm only 13, asshole." She gave Alex the
tongue, and continued playing.
Alex retreated a little after that statement. She was right,
at 13 she shouldn't be in contact with anything sexual. He
was about to give up when she said something that shocked
"What is that thing you do in bed?"
Emma sighed pitifully. "Don't think I haven't seen you do it.
Under the covers… you move your hand up and down. It's like
you're playing with your wiener. I've been watching you
through your door."
Alex stared at her in shock. So she'd been watching him as he
"Huh? Oh, that's something called masturbating… it's
something guys and girls can do."
"But we don't have penises!"
Alex pointed as close to her crotch as he could. "You can do
it with your vagina. Here, let me show you."
He couldn't believe those words just came out of his mouth,
nor could he believe that he was pulling down her pyjama
bottoms to reveal a tiny pink vagina. It was moist. Emma
didn't struggle as Alex directed her fingers in her slit and
moved them about.
Emma shut her eyes and tilted her head back. "Yeah… how did
I not know about this before?"
"I quote from Emma about 2 minutes ago: I'm only 13." Alex
laughed, watching her masturbating in front of him, trying as
hard as he could not to look aroused. He felt the blood
rushing into his penis, making him semi hard, but he was
sitting with his knees by his shoulders so she couldn't see.
Alex gently moved her hands away and rubbed her himself. This
time she moaned. "Oh, that feels good, Alex…" the sound of
her voice whilst she was being pleasured was so sexy that
Alex could have cummed right there and then. But he wanted to
go further than that.
Whilst rubbing her, he stood up and gently pulled his pyjama
bottoms down, revealing his semi erect penis. Emma opened her
eyes to see the said penis standing horizontally from his
"Oh my gosh! Alex!" She began to try and get up.
"Ssh… it's okay, I'm your brother."
Emma calmed immediately, and held her inquisitive gaze at his
penis. He looked at her looking at it, and it gave him a full
"It got bigger!" She smiled at him. "How did you do that?"
"Ah, well I can't control that. It happens when I'm horny."
"You're horny now?"
Alex went slightly red.
"I guess, yeah."
"Well… let me try something I saw once." She leaned back
forward, on her knees, and touched his throbbing dick. "Oh my
gosh, it's so warm!" She jerked it backwards and forwards at
the speed a 13 year old girl would.
Alex was experiencing his younger sister masturbating him
voluntarily. He stood there for ages, just letting her
masturbate him. He felt close to cumming when suddenly he
felt something warm and soft engulf his dick. When he looked
down, he saw his cock inside his sister's mouth. After just a
few strokes of what felt like heaven, he orgasmed hard. She
didn't move her head, though she felt something flying into
her mouth. He shot pulse after pulse of thick white cum onto
her tongue, and he moaned.
"Emma…" he panted.
She removed the cock from her mouth and opened it to show
Alex. He tongue was covered in a thick white layer of his
cum. That was his cum in his sister's mouth. Then she
"Emma!" he continued, "There is no way that was your first
