Summary
     Gee was fascinated with Frank to say the least. Since he and his
     father had moved in, Gee had been watching him in awe. The little
     piece of metal in his lip and nose, the drawings that littered his
     body, the way those drawings glimmered with sweat when Frank was
     outside playing sports with is friends. All of this made Gee's
     stomach swirl with unknown feelings.
     [Fair warning, in this fic Frank is Gee's step brother so this may be
     counted as a bit of incest?? Gee uses she/her pronouns and is rlly
     innocent in the beginning. Mikey doesn't exist in this fic just for
     convenience. There's hints of doubt/noncon and mentions of BDSM. You
     have been warned.]
Notes
     I've had the first chapter of this wrote for a while and I've always
     been to scared to post it because of what others might think. Here it
     is, in all of its shameful glory.
***** Chapter 1 *****
Gee was fascinated with Frank to say the least. Since he and his father had
moved in, Gee had been watching him in awe. The little piece of metal in his
lip and nose, the drawings that littered his body, the way those drawings
glimmered with sweat when Frank was outside playing sports with is friends. All
of this made Gee's stomach swirl with unknown feelings.
Frank was no better off, biting his lip as he watched Gee out of the corner of
his eye. She wore a short tennis skirt with a light pink crop top, her pale
belly showing. Frank averted his eyes, going back to dribble the basketball in
the front driveway. Gee picked and twirled a flower in her fingers, sitting on
the grass. She liked watching Frank show off, knowing he was doing it to
impress her. It made her feel special, even if in a step sibling way.
The sun was slowly fading and so were Frank's buddies as they went home. A boy
name Pete Wentz was the last left, deciding he was staying the night with his
best friend.
Frank sat down next Gee on the grass, his water bottle in hand. "Wanna go in?"
He mumbled, still not used to having a sister. "Sippy." Gee made grabby hands
at Frank's bottle and he handed it over. "Come on," Frank breathed, picking Gee
up off the ground in his strong arms. Gee giggled and wiggled all the way back
into the house and to the living room where Pete was already bothering Ms. Way-
Iero. "I'm gonna go take a shower" Frank shook his sweat soaked hair and Gee
smiled and said 'Ew', her nose scrunched in disgust.
Pete made himself at home like he had been doing for years before Frank moved,
chatting to Mr. Iero about the latest male gossip. Donna, Ms. Way- Iero, took
herself to the kitchen, making room for the new addition of Pete.
▪▪▪
Frank had a grip on himself, groaning at the warm water washing over his soapy
body and the light, feathery touches he was using on his erection. He didn't
hear Gee open the bathroom door at first, only when she spoke up from where she
was standing to pee. "What are you doing, Frankie?" Frank practically yelled,
covering himself from behind the shower curtains "Get out!" Gee almost slipped
and fell rushing out of the bathroom after being screamed at.
What was Frankie doing and why was his thing up? Gee's mind swirled as she
looked into her panties at her own. Should she touch it? Gee decided that she'd
ask Frank again when he was out of the shower and not as grumpy.
Frank dried off his body and hair, slipping on his boxers. He couldn't get his
step sister out of his mind when he touched himself. She was so innocent, so
not knowing. Frank came with the image of her on her hands and knees stuck in
his mind.
Frank and Pete headed up to Frank's room, Gee following after them. "Gee honey,
let your new brother see his friend, you see him every day" her mother called.
Gee pouted and shook her head, "Not enough." She instead sat at the table
waiting for dinner.
▪▪▪
"Frankie!" She screamed, wanting everyone to hurry up. Pete sat in between Gee
and Frank, and Gee gave the back of his head the most hateful glare. How dare
he split them up, Gee wanted to watch Frankie eat. 
Dinner was slow, everyone sticking around to talk about whatever. Frank kept
watching Gee; she was adorable like she had been since day one and Frank
couldn't stop thinking about her catching him masturbating. Did she know what
he was doing? What if she asked about it? What would he say?
This time when Frank and Pete went up to his room, no one stopped Gee. "Let's
play never have I ever" Pete suggested and Frank sighed "What are you? Five?
Besides, Gee's in the room..." "Gee's at least sixteen, she can play." Frank
was having an internal debate, Gee acted much younger than she actually was.
Maybe she wouldn't understand the game and leave? "Yeah, okay."
The game started up and Pete told Gee how to play, Frank still keeping his
distance from her, afraid he might do something stupid. Gee held up ten
delicate fingers proud, "Frankie first!" Pete shrugged and Frank went ahead.
"Never have I ever.. kissed a girl." Frank knew that Pete had been with many
women, as well as guys, while Frank was stuck in his own sexual fantasies. Pete
was the only one to put a finger down.
"Never have I ever, liked bdsm." Frank blushed as his finger dropped. Gee
didn't know what that meant so she just kept her fingers up, "Never have I
ever.." Gee decided to bring up the shower incident again. "Touched my princess
parts in the shower?" She ended the statement as a question. Pete laughed and
lowered a finger "See, this girl gets it." He highfived her and Frankie shook
his head. "No. She does not 'get it'. She walked in on me earlier." "Lower your
finger, Frankie" Gee tisk'ed, grabbing his hand to do it for him.
"Never have I ever slept with a unicorn toy" Frank shot at his sister. "Low..
Never have I ever..  ogled at my sister" Pete laughed out loud and Frank went
red "I don't do that!" "You do." Pete was smiling but Frank felt like yelling
"No!" "You should have saw yourself today, you were basically drooling." "Shut
up!" Frank defended, embarrassment and anger clear on his face. Gee didn't know
what was going on so she scooted closer to Frank. "I bet you masturbate to her"
Pete thought this was funny but when Gee repeated the word, it suddenly wasn't
because Frank had stood up and grabbed him by the neck of his shirt. "Get out.
Shut up and get out!" Frank yelled, just repeating himself as tears welled up
in Gee's eyes. Pete basically jumped down the stairs that lead to Frank's room,
yelling a thanks and goodbye to Mr. and Ms. Iero.
Frank sat back in his spot on the floor and hid his face. He'd fucked up, what
if his dad found out he liked his little sister in that way? Frank fell back
with a groan, closing his eyes and waiting to be eaten by the earth. Suddenly
there was a weight on his chest, but not a bad one. Gee laid herself on top of
her big brother, looking at his face. "Why are you crying, Frankie?" She asked,
putting her head into his neck.
Frank didn't move, not wanting to test the waters with Gee. If he touched her
now, he'd want more of her. She lifted up and pecked his lips, not moving away.
"What are you doing.." Frank's voice croaked. "Kissin. Makes momma happy." Gee
pushed her lips to his harder, still not moving really. She didn't actually
know what she was doing.
Frank yelped when he felt Gee's tongue push into his mouth, lapping at the
inside. He didn't know what to do. He had his hands on her shoulders, ready to
push her off but he couldn't as he felt himself starting to grow half hard in
his pants as Gee made little noises. Gee's tongue worked the inside of Frank's
mouth and Frank pushed his into hers, going with the shared kiss.
Gee moaned aloud and suddenly reality snapped back and hit Frank in the face.
He jumped up and pushed Gee off of him, attempting to scoot across the room
away from the girl. "Did I do something wrong.." She whimpered and he felt his
heart break. "Gee.." She looked up and Frank sighed, "Please leave."
▪▪▪ Okay, it gets weird. ▪▪▪
The next morning, Frank woke up to Gee's body tangled with his. Her hand was
holding his hip, the other under her torso. She hummed when she felt him wake
up, not willing to get back up from Frank's bed. She'd woke up early to
apologize to Frankie but soon found herself curling up next to him.
Her hand slipped off his hip and trailed lower without her even noticing where
she put it. Frank's breath hitched and he was suddenly awake, hot everywhere.
He was naked and his little sisters hand was on his limp dick. "Oh god." Frank
moaned as Gee's hand clenched as she woke up.
"Frankie.." She yawned and Frank's hips bucked into the hand that was now
holding his growing member. Gee saw what she saw in the shower once again and
the memory came running back. "Is this how you maskturbait?" Gee asked, not
knowing how to pronounce the word Pete had said last night. Her hand moved up
his length and Frank was frozen. She tried to mimic the movements she saw
Frankie doing in the shower, her hand speeding up, stroking her stepbrother's
cock.
Frank's head fell back as his judgment was blinded, letting pleasure build up
inside of him until he was about to tip over. Frank grabbed and stilled Gee's
hand, switching positions and putting Gee on her belly. "What are you-?"
Frank's dominate side took over completely, "Shs, Geebear. Be good for big
brother." Gee didn't know what was going on but the feeling of pure happiness
was filling her abdomen as Frank breathed into her ear, calling her a sweet
name.
"Want Frankie to make you feel good?.." Gee shook her head yes and Frank
moaned, stroking himself, sitting on the backs of Gee's thighs. Frank lined
himself up with her soft ass, not going in but rather fucking her ass cheeks.
"Oh?" Gee didn't know what to think of the movement. Frank's rough hands
gripped her bottom as he fucked himself fast and hard against her buttocks.
He wanted to pound into her, open her virgin hole up and use her for all that
she was worth, but he knew he'd hate himself afterwards, this was bad enough.
His hips shuttered and soon he was spilling onto Gee's pale backside.
He held himself over her, looking at the mess he made of his delicate step
sister. She was panting and moaning, confused by her own body. Frank flipped
her over and held her member, squeezing in gently in his hand. "Ow, Frankie."
Gee complained, not liking the tight pressure until his hand moved up and down
her length. Gee couldn't stop herself as she moaned. Frank kept a steady pace,
pumping her with fluid motion until she came into Frank's hand. "Good girl.."
Frank coo'd, milking her though her first orgasm. He couldn't wait to take her
virginity. He already wanted more.
***** Chapter Two *****
Chapter Summary
     Gee and Frank are getting closer, and Lynz gets involved.
The next day before Gee and Frank's parents left for work, they told Frank he
was in charge. He planned to take full advantage of that.
"Gee.. wanna come to my room?" Frank asked Gee from where she sat at the dinner
table. Of course he felt bad for what happened yesterday. Gee almost spilled
the beans that night. Lucky for Frank, he stopped Gee before she could get it
out.
"Okie dokie." Gee said childishly, "Finished." Gee held up her drawing. It was
of a boy with black hair that swooped infront of his face- It was clear to see
that it was Frank- and a princess with red hair.
"Who's the redhead?" Frank leaned on the back of Gee's chair, looking over her.
"Me! I'm gonna color it one day." Gee smiled up at Frank. "It's us, Frankie, do
you like it?"
"I love it, babydoll." Frank took it from Gee's hands, noticing her wide toothy
smile. "Can I keep it?"
"Yes! Did I do good?" Gee asked, taking her feet out of her chair and standing
up.
"You did so good. Maybe you deserve a prize.." Frank moved closer to Gee.
"Frankie." Gee breathed when Frank pressed himself against her. "Yes, Geebear?"
Frank growled into Gee's ear, his thigh going between hers.
"W-What's happening." Gee moaned softly as she began to get hard against her
step brother's thigh. Her hips bucked up without her meaning to and her knees
felt weak.
"You're getting turned on, baby." Frank caught her earlobe between his teeth,
nibbling at it and tugging it away. "F-Fr-" Gee stuttered, whimpering Frank's
name and only getting out a couple letters.
"How about I take you upstairs and teach you a few things?" Frank loved Gee's
innocence, but what was even better than that was him getting to ruining it.
Gee nodded and Frank lifted up her thighs, letting her arms go around his neck
to keep herself up.
Frank carried Gee to his room, setting her on his mattress and staying between
her thighs. He pulled her bottom half close to his, grinding against her
softly. "Feel that?" Frank's voice was rough.
"Why is it like that, Frankie?" Gee's voice was high pitched and whiny, her
chest rising fast and her heart beating hard in her chest.
"It means you like it when I do this."' Frank moved his hips forward, pressing
his erection against Gee's own. Her head tilted back and a ragged sound left
her lips. "I do."
She was panting, wanting Frank to touch her so bad it hurt. "Please, Frankie."
"Please what, kitten?" Her heart fluttered at Frank's name for her. She thought
of her as a little kitty all curled up in her strong big brother's lap, purring
cutely.
"Plea- Oh gosh." Gee's back was arching as Frank's mouth met her collarbone.
The way she moved had Frank leaning over her, making her feel so small and
defenceless.
Frank pulled back before he could leave a mark, looking at the pale flesh
covered in is own spit and just a tint of red.
"Wh-y did you stop?" Gee whined, her hips bucking up to move against Frank's.
"Can't mark you all up yet. Can't let people know you're mine."
Frank's breath was taken away as Gee jumped forward, making there lips come
together. Her mouth was on his in an instant, her tongue dipping inside of
Frank's mouth.
"Babydoll-" Frank murmured against Gee's lips, pulling away and looking into
her innocent eyes.
"I like that a lot, Frankie.." Gee sighed, falling backwards on the bed. "Feels
so good."
Frank cleared his throat, sitting down in the middle of his bed. "We don't have
to stop." Frank couldn't help but love his sisters lips. They were so soft and
tasted like candy. Her whimpers and moans feeding all his fantasies.
Gee crawled over Frank, laying down on his chest. Her legs tangled with
Frank's, her head going into the crook of his neck. "Frankie?"
"Yeah, Gee?" Frank was staring straight up at the ceiling, his arms wrapping
around Gee's frame.
"Do all brothers and sisters do this?" Gee sounded confused, her eyebrows
scrunching together.
"Well, no." Frank sighed, pulling Gee tighter against him. "Oh."
"It's not a bad thing.. I don't think. I mean, we're not really related." Frank
quickly added, wanting so badly to justify his attraction to his baby sister.
Gee pushed herself up, using her elbows to keep her balance. "Can I give you
kissies again?" Gee looked shyly at Frank's lips, her own opening slightly.
Frank gave a gentle nod and leaned up, pressing a sweet kiss to Gee's lips. She
let out a content sigh and tilted her head sightly, Frank's tongue barely
ghosting over her lips.
Their mouths worked together slowly, Frank slipping his hand under Gee's skirt
to grip her ass. He just barely dug his nails in, making Gee whimper.
They jumped apart as soon as there was a loud knock on the door. "Gee! Come out
and play!"
"Who's that?!" Frank whisper-yelled, looking out his window. He couldn't see
the door from it so he turned to Gee.
"It's my friend Lynz!" Gee squealed, running straight for the stairs. "Come
on!" Gee motioned behind her for Frank to follow.
Frank's hard on was slowly dying and he wasn't very happy about this 'Lyn-z'
person showing up and ruining his fun.
They made it down the stairs, Gee going room the door and unlocking it as fast
as she could. "Gee, wait! I'm in charge!" Frank didn't want Gee getting
kidnapped by opening the door for strangers.
The way Gee embraced this Lynz girl showed that she definitely wasn't a
stranger. "Oh Frankie, this is my best friend! Lyn, this is my big step
brother!"
"More like small am I right, " Lynz laughed. "We're like the same size!" It was
kind of pathetic Frank was the same size as a girl younger than him. She was
wearing tall boots, okay!.
"Frankie, can me and Lynz go outside? Pleaseee." Gee stretched out the word,
making it that more adorable. Lynz seemed younger than Gee but mature. He still
didn't want two small girls outside alone.
"Yeah. I'll go with you." Frank grabbed his old beat up shoes, slipping them
on. "Gee, go put on some shoes, we'll be right here."
Gee ran to her room down the hall, the one she has been going to quite less
since her and Frank had started getting close.
"Hi, Frankie." Lynz laughed at nothing, scooting closer to the boy she had just
met. "You know, you're really cute to be Gee's brother."
"Um, step. Stepbrother." Frank clarified, taking a step back. "Thank you?"
Frank pulled a confused face. What was that supposed to mean?
"I'm back!!" Gee yelled, jumping between the two. "Outside!" Frank giggled,
smiling at Gee's childishness. Lynz scofted before smiling sweetly at Gee.
They made there way outside, Frank grabbing his basketball and walking out onto
the driveway. Gee was walking to sit in the grass but Lynz stepped in front of
her before she got there.
"Let's play hide and seek, Gee." Lynz smiled, grabbing Gee's hands. Gee smiled
right back, nodding her head yes.
"I get to hide first!" Gee called out, making sure she did. "Of course." Lynz
stepped back, putting her hands over her eyes and starting to count. "1,"
Gee rushed to find a hiding spot, running to the side of the house just to get
out of sight.
"15," Lynz was almost to twenty and Gee was quickly deciding where to hide. She
ducked behind a garbage bin and sat on the ground, waiting until Lynz would
either find her or give up.
"20. Ready or not, here I come!" Lynz shouted, walking over in front of Frank
who was concentrated on his shot.
"Frankie, Frankie!" Lynz tugged at Frank's wrist, pulling him out of his zone.
"What's wrong, Lynz?"
"I lost Gee! We were playing hide and seek and I've looked everywhere outside.
Please help me look inside!"
Frank's eyes widened. "Are you sure she's not outside?" Fuck, he was supposed
to watch her.
"Really, Frankie. I searched everywhere. I think she's hiding in your room
because she knows I wouldn't go there."
"Come on, I'll take you there." Frank walked ahead of Lynz, dropping his ball
in the carport before closing it and taking Lynz inside. "Lock that door, I
don't want her going out the front to try to find us when we're already in
here."
Lynz nodded, locking the door and grinning to herself. "Your bedroom?"
"Right." Frank walked up the stairs, Lynz hot on his tail. "Gee?" Frank called,
walking into his room and scanning the mess. He walked over to the bed, looking
under it, he opened the closet and picked up his dirty clothes. Gee wasn't in
his room.
"You sure she's in-" Frank turned around, only for Lynz to cut him off by
jumping onto him. Frank fell backwards onto his bed, Lynz's legs wrapped around
him.
Her hands cupped Frank's face as she forced a kiss on his lips. Frank
struggled, trying to push her off of him, but they were the same size and Frank
couldn't just easily lift her off.
Frank went to protest and Lynz used the chance to slip her tongue into his
mouth.
Frank started to calm down, letting Lynz kiss him. He really shouldn't be doing
this. Lynz was his step sister's best friend. Not to mention, only around 16
while he was almost 18.
She took Frank's hands in hers and moved them under her skirt. He let her.
Frank slowly gained confidence, gripping her ass and kissing her back.
"Frankie.." Lynz whimpered grinding down and getting Frank hard. It wasn't
Frank's fault he was a horny teenager, he was really turned on by the friction
from the girl in his lap.
"Oh wow." Frank breathed, sitting up and reconnecting their lips. Lynz's kiss
was as sweet as battery, while Gee's was soft and slow.
"I know what's going on. I saw the way your hair was all messed up when you and
Gee answered the door. The way you were breathing hard. I know what you two
do."
Lynz sat up, moving in Frank's lap, enjoying the way his erection felt against
her. Frank couldn't form a response as he moaned, pushing back against the
girl.
"You looked so fucking sexy. What does she have that I don't? I have boobs.
They're all yours Frankie." She pulled her shirt over her head, taking off her
bra right in front of Frank.
"Touch em, baby. Please." She practically begged like a whore, taking Frank's
hands from her ass and pushing her breasts against them, making him cup them.
"Your hands are so warm, feel so good, Frankie." Lynz was really making it hard
for Frank to say anything. Even if he tried, it'd come out in a desperate moan.
"Got condoms?" Lynz asked and all Frank could do was stutter "D-Drawer," before
he reached over to find them.
Lynz pulled down Frank's pants, palming him before taking him out of his
underwear. She created a fist around his cock and jerked him a few times.
Frank's head went back with a groan, Lynz pulling away to take the small piece
of foil from him.
Lynz opened it with her teeth, some of her lipstick spread off her lips from
kissing Frank so hard. Some of it left on his face.
Frank's cock was standing proud, him extremely turned on despite the situation.
She rolled the rubber onto him and positioned himself over his cock.
Moving her panties out of the way, Lynz sunk down slowly. Lifting her hips back
up, she dropped down again. By the time she sunk all the way to Frank's base,
they were both howling in pleasure.
One of Frank's hands was playing with her soft breasts, the other was on her
nice ass. She let Frank almost slip all the way out before sinking back down on
him.
Frank totally forgot about finding Gee, because right now his cock was buried
in a really hot girls pussy and that was enough to make any bisexual boy forget
anything.
Lynz leaned forward, pushing her breasts into Frank face. Her hands went behind
his head as she bounced on his thick member.
Frank was so close to cumming, rubbing his face between Lynz's boobs. He was
panting and moaning, both his hands moving to grip her hips.
"Frank Anthony Iero Jr., why in the world did you leave your little sister on
the lawn!" Frank almost had a heart attack as his dad yelled from downstairs.
"Get off of me!" Frank yelled, trying to push Lynz off. "So close, gonna make
me cum." Lynz moaned, speeding up and clenching down on Frank's swollen cock.
"Daddy!, Oh God." Lynz shuttered, Frank deep inside of her as she came.
Frank couldn't stop himself. Hearing someone moan those words for him was too
much, making him shoot hot cum into the condom. His cock twitched as he let out
a low growl.
"Do you have a girl up there?! Get your asses down here this second."
