The night was going to be perfect. Phineas and Isabella had finally told each
other how they felt and even went out on a few dates. As summer was coming to
an end Phineas had one more surprise for Isabella. His only question, “Is she
ready?”
Phineas had snuck into Isabella’s room, “I have something I want to show you,”
He held out his hand, “I promise I will have you back before morning.”
Without question she took his hand.
He pulled her close, “Close your eyes,” he said jumping out her window. Phineas
knew how much Isabella loved Aladdin, so he came up with a way to make a flying
carpet.
She was enjoying the ride, when the carpet circled a spot in the park where a
beautiful picnic was set up by the creek. “Wow, Phineas.” Isabella ran over to
the blanket, “This is amazing.”
“I was hoping you would like it.” Phineas smiled happily. “There is more to the
surprise.” After the picnic the two enjoyed a moonlit walk, to a cabin Phineas
had put together earlier in the day, “I built this for us.” It was in a less
populated area, so people just thought it should have been there.
Isabella ran inside, “It’s beautiful, but why build us a house? We’re still too
young to move out.”
“I know, but that’s not why I built it,” Phineas pressed his lips against
Isabella’s. His tongue brushed against hers begging them to part, as his hand
cupped her chest.
Isabella pushed him back slightly, “Whatch doin?” she asked in a way that
really got to him.
“School is starting back soon,” Phineas said, “and, well, I wanted to give you
‘moonlit and rose petals.’I read it in a book.” Isabella looked confused, she
was head over hills for Phineas, she just wasn’t sure if she was ready to move
past kissing. He walked her to the bed, “I won’t do anything you don’t want me
to. You know I wouldn’t force you to do anything you’re not comfortable doing.
If you want me to, I can take you back to home now or we can just stay and
cuddle.”
“No!” Isabella exclaimed, “I don’t want to go back yet. I’m just nervous all of
a sudden.”
“It’s okay, I understand. I always get nervous when I’m around you.”
“Kiss me again?”
Phineas smiled and kissed Isabella again. He laid her back on the bed, his hand
rested on the small of her back. He deepened the kiss by brushing his tongue
over her lips, this time they parted. Their tongues brushed as his had found
its way under her pants. His fingers quickly found her sweet spot as he rubbed
her through her panties. She moaned into his kiss.
The fourplay was enough to drive a person insane. They slowly teased each other
as they undressed, nerviness gave way to passion. They tried many non-
penetrating positions such as Mammary intercourse (see notes at bottom) and 69.
When Phineas couldn’t take it any longer, he took control. He gently pushed
Isabella under his body. “Take a deep breath,” he whispered into her ear, and
Phineas thrust his shaft inside Isabella. She gasped at the loss of her
innocents, while he nibbled her neck and waited for her to catch her breath and
adjust to his size.
“Take it slow,” Isabella said, letting her partner know it was safe to move.
Phineas slowly pulled out pausing, then pushed back in. It didn’t take long for
Isabella to meet him thrust for thrust. Both became lost in each other; their
hips bucked as one.
 Moaning, gasping, exploring.
“Oh, Isabella.”
“Phineas, yes, Phineas.”
With one last thrust they hit their climax together. Phineas collapsed onto
Isabella breathless, as Isabella panted incoherently. Her walls clamped around
his shaft as his seed filled her. They dosed off in each other’s embrace.
The two refused to let school stop them from enjoying each other’s salty sweet
nectar. Once Phineas passed his driving test, he and Isabella celebrated in
their cabin. She Started by giving him a nice teasing BJ, that quickly turned
into more. The two became lost in the throes of passion; Phineas entered, and
exited Isabella’s body and he teased her nipples. He enjoyed the sounds
Isabella made, and she enjoyed the way he made her feel, testing her limits,
and pushing her body to see just what she could endure as they tried new
things.
Midway through their 10th year of school when Isabella started missing school.
She had been sent home early several days and Phineas started to worry. He
decided to visit Isabella, but her parents wouldn’t let him see his girlfriend.
When he noticed Isabella’s family leaving the house without her, Phineas when
to see her. The house was quite as he made his way to the bedroom. He saw
Isabella curled around her pillow. She looked different somehow.
“Isabella,” Phineas said, his tone showed concern, “Isabella, are you awake?”
Isabella whined when she felt the bed shift and Phineas lay down behind her,
“Please don’t make sudden movements,” she whispered, “I don’t want to start
throwing up again.”
“I was so worried about you,” He buried his face in her hair and inhaled
deeply.
Isabella cuddled into Phineas, “You, were?”
“Why wouldn’t I be?” Phineas looked shocked. “You’ve missed a lot of school,
and you’ve been sick a lot,” he ran his hand down Isabella’s arm, “Your
parents, and sisters, have made it imposable for me to see you. Isabella,
what’s wrong?”
“I’m pregnant,” Isabella sat up, “that’s why I’ve been so sick. It’s because
I’m pregnant. And they are made at you for knocking me up.”
“REALLY!! Isabella that wonderful. How far along are you?”
“About 6 weeks.”
Phineas pushed Isabella back, laying between her legs. Right then, in that very
moment, Phineas wanted to show Isabella just how much she meant to him. “I want
to make love to you,” he leaned in pressing his full weight on Isabella, his
warm breath tickled her ear as he whispered sweet loving words to her. She
breathed heavily, unable to hide her moans, his fingers intertwined with hers.
“Do you want me too?” he asked, before pressing his lips to hers, sliding his
tongue along them begging they part.
Her hips bucked automatically as her lips parted, allowing his tongue access.
His hands moved over her body gently playing with her chest. Before she could
process anything, Isabella was stripped. Phineas left a trail of kisses down
her body, her feeling of sickness was replaced with passion, longing, and a
hint of lust. Isabella’s eyes rolled back, her hips bucked at the feel of a
tongue flitting across her clit while fingers toyed with her entrance, “Mmn,”
she moaned. ‘This sensation, I don’t want this to stop.’ Phineas nipped her
clit as his fingering quickly turned to more. Isabella gasped and moaned. She
was feeling pleasure like never before.
He withdrew his hand and got into position, “Do you want me to stop?” His lips
pressed against hers. “Right now, I want to make you feel like your living in a
dream. I’ll do whatever you tell me to Isabella, just tell me what to do.”
“I want you,” Isabella said, “The good and the bad, no matter what, I’ll always
want you.”
Phineas whispered, “By the time I’m done you will have forgotten your name.” He
pushed into her slowly. He waited for he to adjust to his size before,
withdrawing and pushing back in. He let her get use to him before increasing
speed. He sucked her chest, and played with her nipples nipping, pinching, and
twisting them. “Isabella, Isabella,” he moaned.
“Phineas, Phineas.”
Both hit their climax together. Phineas lay on Isabella, kissing her neck,
sucking her nipples, while his warm seed shot into her filling her full. Before
they drifted off to sleep, Phineas whispered, “I hope we have a little girl,
just like you.”
Chapter End Notes
     Mammary intercourse is a non-penetrative sexual activity sometimes
     done during foreplay. It is also done as a safe sex alternative to
     intercourse. In most instances, this sexual activity involves the man
     placing his penis between his partner's breasts. He then thrusts
     while the breasts are squeezed around the penis for more excitement,
     and sometimes combined with oral sex.
***** His Siters Torture *****
Chapter Summary
     Candace gets Phineas grounded so he get pay back.
“Candace, Candace, it’s time to wake up now,” The cold voice of Phineas said.
Candace felt the sharp stinging of a whip hit her sensitive vagina. She found
herself hanging in the center of a hidden room, her legs separated by an
extendable bar. She cried out against the pain causing her to get hit again.
She wasn’t sure how long she had been bound for, but she did know, no one was
coming to help her.
“Phineas why are you doing this?” Her brother switched to a cat-of-nine-tails.
He had tricked Candace into thinking he needed her help with his new video
game, but when she went to his room, she was met with chloroform. “I don’t
understand,” The leather knotted straps bit into the bare flesh Candace’s
vagina and thighs, making her cry, “What’s wrong with you, why am I naked, why
are you naked, and where are we?”
“Tell me sis, have you fucked Jeremy yet?” Phineas responded with his own
question. He brought the 9 knotted leather straps down on her chest and her
back.
“AAAHH!! How could you even ask me that!”
“Because this will be a lot easier if you have, Candace,” Phineas said,
standing behind his sister with a rather large arrow shaped sex toy.
“Phineas what are you going to do with that?” She was struggling against the
chain that held her arm above her head and the bar holding her ankles, “Just
let me go and we can forget this ever happened.”
Phineas was enjoying torturing his big sister. “Sorry Candace, I can’t do
that,” malice radiated from his voice. He placed the arrow tip to his sister’s
neck and turned it on. The toy vibrated through her spine as he slid it down
her back and to the tight hole of her ass. “You see, you’ve gotten me grounded
for the last time,” Candace was unprepped and the arrow wasn’t lubricated, “If
you relax this won’t hurt you too badly.”
She felt him smirk against her shoulder, as he brutally rammed the vibrating
arrow into her ass. “Uhh…Take it out…Please…It’s to big…” Candace arched her
back, screaming, as her walls closed tightly around the foreign object tears
streamed down her checks. “Please take it out…It hurts…Take it out…”
“What’s wrong Candace, are you in pain?”  He asked sarcastically, pinching,
twisting, and yanking her nipples; he pressed his thick erection against her
back. “Your nipples are so hard, it’s like they are begging to be squeezed,”
Phineas nipped his sister’s shoulders; picking up two objects, he placed them
on Candace’s chest. “Your tits are a lot bigger than Izzy’s,” He grabbed his
electric wand, turning it on he ran it between his sister’s breast, down her
stomach and over her clit.
“Stop, Phineas please, stop. Don’t do this…” he ran the wand over her slit
before sliding it in her entrance, hitting the release and turning it to its
roughest setting, “Stop…NO…”
Phineas removed the chain holding Candace up and replaced it with one attached
to a small bed. Her body was stretched as far as humanly possible. “You’re so
wet there already,” his fingers moved over her sweet spot. He held her lower
lips apart with his thumbs and licked her clit. She wiggled, and teeth clamped
down, his tongue moved in and out of her folds, “and tight.” Without warning he
forced his fist deep inside her walls, causing her to scream at the force and
pain of her ripping Hyman. “Looks like Jeremy got lucky,” Phineas pumped his
fist in and out of her as he bit and sucked her clit, “your virgin juices are
getting everywhere.” He loved the sounds she was making and the pain he was
inflicting on her.
“Please stop, that hurts too much.”
As violently as Phineas’ fist entered her, it was ripped away. Gasping for air
Candace felt something being forced into her mouth. “If you bit me I’ll you
will regret it.” All Candace could do was whimper. The vibrations sent waves of
pleasure through Phineas. He began to thrust harder and faster going deeper and
deeper, gagging Candace. His hot salty sticky cum shot down her throat as he
reach his first climax. She choked on his load as most of it ran from her
mouth. “I’m going to shove my cock inside of that tight little pussy and fuck
you so hard.”
“Please, Phineas enough,” she whimpered. “I’ll stop trying to get you in
trouble, just please no more.”
“I’m just getting started,” Phineas said as he thrust his erection inside of
her and began moving very hard and fast.
“No…Stop…Please don’t…Your hurting me…Get off…”
He withdrew completely unloading his seed or her stomach and chest. “Let’s see
how you like my toys?” With one swift motion Phineas yanked the arrow out of
Candace’s ass, replacing it with a 12” x 3” spiked dildo. The pain was enough
to cause her to lose consciousness, but Phineas wouldn’t allow her that peace,
as he turned the speed setting to max. Her orgasm never ending.
“Stop…Please…No…Stop…Please…Please Stop…”
Phineas continued to torture Candace throughout the night. He wasn’t holding
back at all. He was unforgiving as he enters her body over and over again at
times pulling out his entire length savagely thrusting back in and pushing her
body far beyond its limits, giving BDSM a whole new meaning.
Hot wax dripped on her breast from a hanging candle Phineas rigged. By this
point Candace had stopped resting, so he decided to unchain her. She felt him
spread her lower lips, and without warning his hand came down hard on her sex.
She squeezed her eyes tight and clinched the sheets gritting her teeth against
the pain, vibrating through her, tears fell from her eyes. When he finished his
assault she was raw, swollen. He rubbed his tip against her, getting into
position, he started sliding into her entrance. Tears slide down her checks and
he thumbed them away.
“Please don’t make me do this anymore.” Candace said. She felt pain shoot
through her vagina. “Stop,” she cried, “I’m too raw.”
“Candace, you disappoint me,” He thrust into her as far as he could, continuing
his assault.
“Phineas please don’t. Please. Stop…Please stop.”
Before long, Candace found herself suspended in a sex swing, arms behind her as
her brother punished her ass. After reaching his climax, Phineas made his
sister get on her knees, so he could have a little fun with his riding crop:
hitting her breast, her sex and ass, arms, and back telling her she had brought
this upon herself. The next thing she was forced to was suck him off while he
played with the settings on the vibrating electrodes he placed in both of her
holes.
“You’re getting off on this, aren’t you?”
“NO!!”
“But your body says different.”
“I hate this, hate what you are doing. I’m your sister.”
He pressed into her, as his nails dug into her thighs. “That’s not how I see
you.” He flicked her right nipple before twisting it between his fingers,
“These are nice,” Phineas rubbed his face between Candace’s chest, as his shaft
moved in and of lower half. He yanked and kneaded her breast, spanked her flesh
and toyed with her clit. “I figured we were having fun at this point,” her body
instinctively arched as she wriggled under his sadistic taunts. Phineas circled
his tongue around Candace’s left nipple flicking it occasionally, sucking and
biting it hard. By this point she was becoming use to the pain he was causing
her. She continued to fight him, but she was held her in place. His hands ran
up and down her body again and again. Nails pierced the sensitive skin of her
inner thighs, forcing her to moan. Candace wasn’t enjoying her captivity, but
by now she had lost all control of her actions.
***** Hey Mom *****
Chapter Summary
     Isabella cut Phineas off. Now the sex deprived teen decides to have a
     little fun with his idle crush.
“Hey mom,” Phineas called from the other room, “Your Lindana right?”
“Why do you ask?” Linda replied.
“I found this while I was looking through some old stuff.” The teen, was
holding up Linda’s stags costume. “Would you mind letting me see you dressed
up?”
“I guess I can, for you.”
When Linda stepped back into the room, Phineas stepped in behind her. His hands
squeezed her chest, his desire evident. He didn’t care this woman, was his mom.
Phineas had a thing for the Idle Lindana, and Isabella had cut him off. He was
just looking for some form of sexual relief.
“What are you doing?”
“What does it look like?” Phineas let his hands move over Linda’s body. She
tried to fight him off, but her son was to strong.
He yanked her shirt, ripping it open, exposing her full round breasts. He
pinched her nipples, twisting them. “You’re so hot, I just want to bend you
over this table.”
“Phineas, stop this now.” His hand slid under her skirt and into her panties.
“Stop! Don’t touch me there!”
“Where,” he said, teasingly and started rubbing her clit. “You mean here, don’t
you? You don’t want me playing with your pussy, do you?” He licked her ear, and
pushed her onto the table. “I’m going to enjoy this Mom.”
Linda felt her wrist being restrained as Phineas started fingering her, “Stop!
No!” Her panties were ripped of. “You need to stop.” The sound of a zipper told
Linda, her son wasn’t listing. She felt pressure against her folds as Phineas
pushed the head of his cock into her slit.
Slowly his shaft moved deeper and deeper spreading her apart. “I think I’ll
take my time with you. I don’t want this to be over before it starts.” Phineas
slowly pulled out and pushed back in; his hands grabbed Linda’s chest again,
pinching and twisting the nipples. The more Linda told him to stop, the quicker
and harder his thrusts became. As he hit his first climax, Phineas withdrew,
his hot cum poured onto Linda’s back. He walked around the table placing his
tip at her lips, “Look at this mess, you should clean it up.” He forced his
cock into her mouth. The harder Linda fought her son the worse and more
demanding he became, “Come on, suck me like you mean it.” As she was forced to
suck him off a hand came down on Linda’s bare ass. She yelped around his cock
in both pain and surprise. The hand came down on her ass again and again.
Phineas loved the reaction he was getting form Linda. He began to grow wider
and longer with each yelp until he came again, this time he shot his load down
Linda’s throat. “Oh! Fuck yes mom!”
 Phineas removed his shrinking shaft from Linda’s mouth. He undid her
restraints as she coughed, chocked from his seed. Phineas repositioned her on
the table and secured her restraints again. She begged him to stop, but he
pretended not to hear her. Linda felt a pressure at her entrance; Phineas
slipped three fingers in her slit, his mouth closing around her clit. Linda’s
body reacted on its own, bucking and arching. This was a feeling she wasn’t
familiar with. He hungerly sucked her clit, nipping and licking it. He could
tell she was getting close to her climax, and decided to press his thumb into
Linda’s ass, pushing her over the edge. Phineas lapped her juices, eating her
out.
She lay panting, when his tip entered her again, sliding as far into her as he
could. At first, he moved slow, but quickly quickened his pace. Linda pulled at
her restraints, “Stop! No! Mmn! Phineas Stop! Ahh! Don’t do that! Mnn!”
He moved faster and harder, pounding Linda’s pussy. Her walls clamping around
him as she hit orgasm after orgasm, while he played with her clit and ass.
Linda knew this was Wrong on multiple levels. Phineas was her son and he was
raping her, but she couldn’t stop the pleasure she felt. She begged him to
stop, but her body wouldn’t stop screaming for more.
She felt something pinching her nipples, followed by a low volt current. She
moaned and arched at the feeling. The sound pushed her son over, she gasped as
he pulled out suddenly and unloaded his seed on her stomach. He didn’t leave
her empty long; his cock was replaced with a ribbed vibrator he’d set to its
highest setting.
“Enough Phineas, I can’t…Stop this…Take out..Phine…”Linda’s words were becoming
incoherent as she wiggled, trying to push the object out.
“Just stop fighting and let me show you what true pleasure is.”
The things her son was doing to her, the way he was touching her, Linda was
pushed to the point she blacked out. When she woke up she was tied to a bed,
her son fucking her ass, the vibrator still deep in her pussy, the nipple
clamps still shocking her. All she could think; how much could her body take.
