The shadows of tree branches projected by an outside streetlamp dance across the ceiling of Allyson's upstairs bedroom. Thunder was rumbling in the distance, and the wind leading the oncoming storm steadily increased. It was late evening, and the storm would be there before midnight.

Allyson loved thunderstorms. The preceding winds would soon be joined by the patter of rain on the roof as the thunder grew louder and the lightning lit up the sky.

She acquired her love of thunderstorms from her mom, who cuddled with Allyson as the storms rolled through, providing her with excitement and comfort. Allyson wished her mom was here to comfort her now. A sudden illness plagued her, and after a hard fight, her mom succumbed to her affliction and passed away eight months ago. It seemed so long ago, but sometimes it felt like yesterday.

The wind blew harder, and the thunder drew closer. Allyson sighed.

She thought about how her mom's passing affected her dad. It was like all joy in life was sucked out of him, and Allyson had no way to help. At least she was there for him. She delayed her first year of college to be with him as they moved past their grief.

A loud clap of thunder and the bright flash of lightning shocked Allyson out of her malaise, and she decided to relax and enjoy the storm.

The rain was moving in, and Allyson shifted her focus to the dancing shadows, the thunder, and the rain that would soon be dropping torrents against the roof and siding.

While the storm increased, Allyson noticed a small itch on the inside of her thigh and reached a hand down to it to scratch. Being without panties, the itch was easy to get to.

Allyson never wore panties to bed. It was a practice her mom had taught her. Her mom was a big woman and would be considered an SSBBW. Allyson grew up chubby and as she matured, her body followed suit.

Her mom would say, "Us bigger girls need to let our parts get some air overnight." So, Allyson did what her mom always professed.

The itch was situated where her upper thigh met her plump vulva, and there was no getting around rubbing against it. The itch subsided but the pleasure of touching the sensitive mound of flesh did not. So, Allyson lightly rubbed her chubby mound as the shadows danced faster and the storm increased ferocity.

She took two fingers and worked them towards the slit of her vagina. She could feel the warmth and moister increase as she moved deeper. She caught some of the juices that were secreting and used them as a lubricant as she worked her fingers up her slit to where her labia met. Her clit was already starting to protrude, and the first touch sent shivers through her big body and caused a stream to flow from her pussy down to the crack of her ass.

The storm was raging overhead. Thunder crashed as the wind howled and the lightning lit the room as it flashed across the sky.

Allyson felt an orgasm welling up. She knew that if she continued, she would gush a stream of her juices wetting the bed. She didn't care! A couple of more strokes and...

Suddenly there was a loud thump against the outside wall, followed by the crash of glass breaking and wind rushing into the room!

Allyson yelled in terror over the sudden surprise. She leaped out of bed and out of the room into the narrow hallway.

Her dad rushed out of his room and met her there, immediately grabbing and hugging her.

"It's ok Allyson," he said soothingly. "Are you alright?"

"Yes," Allyson replied. "I'm just startled. The window broke and there is rain getting in."

"Alright. I will get in there and get a temporary fix going," he said. "You relax. Go into my bed and try to get back to sleep." A third bedroom was occupied with items the two of them had been packing away after her mom's passing.

"Thanks, Daddy. I love you," Allyson said with a hug.

Her dad watched her walk toward the bedroom and noticed her exposed large rear end as she made her way down the hall.

"She takes after her mother more and more every day," he thought.

Allyson climbed into bed and found it warm and comforting. She did her best to relax, but between the excitement of the storm, the window breaking, and her impending orgasm, she was still a little wound up. She thought of continuing her masturbation, but she decided this was just not the place, so she denied herself the relief of rubbing one out.

She slept, but it was light enough that she was aware of her dad entering the room and preparing himself for bed. He quietly moved and was careful not to stir her as he climbed onto the mattress and under the covers. Allyson lay on her side facing the outside of the bed and her dad moved slowly. Spooning up behind her, he put his arm around her and gave her a gentle hug. It made her feel safe and comforted. It also made her feel aroused!

She could feel every inch of his body that was in contact with her, especially where he spooned against her big ass. Then she felt something pushing against her butt cheek.

"What is that?" she thought in her half-asleep stupor.

It grew harder against her, and she suddenly realized that it was her dad's erection. Just as quickly as she came to that realization, her dad promptly moved back from her and turned over.

She was able to slip into a light sleep soon after calming down from having her dad's boner pressed against her bare backside.

She had no sense of how long she had slept when she was awakened by the bed shaking gently.

"Now what?" she thought, as she noticed her dad's deep breathing accompanying the rocking of the bed.

His breathing increased as the shaking became more frequent followed by a muffle grunt. Then it all subsided.

Allyson was exhausted and finally fell into a deep sleep.

"Hey baby girl, I'm leaving for work," Allyson's dad said the next morning as he kissed her forehead.

Allyson acknowledged him with a short, "Um huh." And she slept for another hour.

When she woke up, she recalled all the events of the night from the storm arriving to the bed shaking.

"Was my dad jacking off?" she thought to herself as she removed her nightshirt and headed for the shower.

She set the water temperature fairly hot and stepped in. Allyson began washing her hair, and after rinsing, she grabbed her body wash. She worked up a good lather in her hands and squirted a fair amount onto her breast. She used a scrunchy to wash her armpits, then she rubbed her big firm tits with her hands. The size made them hang down and fall to each side of her big belly. She lifted both to get underneath and rubbed circles on her three-inch diameter areola that responded to the stimulation.

Next, she took care of her big belly, and she soaped it up from under her breasts to where it overhung her fatty upper pubic region. She played with it, lifting it and flopping it against her fupa. She thought her belly was beautiful and a sign of true womanhood.

Next came her vagina, and it was not an easy feat. Allyson took a good amount of body wash in her right hand and steadied herself with her left against the shower wall. She slightly spread her legs and bent her knees enough to be able to reach her arm around her belly to her fat pussy. She rubbed the body wash all over her mound and into her slit and inserted her fingers into her labia. She took a soapy finger into her hole and swirled it around. It felt good to get it clean and she felt sexual arousal take hold. She moved two fingers that were lubricated by the soap to her clit and made a couple of upward swipes at it and immediately felt the muscles inside her pussy constrict in orgasm. Her legs became wobbly and weak, but she kept her balance. She gushed her juices that mixed with the shower water as they ran down her legs. The squirting seemed like it would never subside. She had cum hard, and slowly recovered and stood upright.

"Oh my, that was a long time coming," she thought as she meticulously dried herself and every fat fold. When you are a big girl, you have to make sure everything is dry after your shower.

Allyson was off work for the day, so she occupied her time completing housework and preparing for dinner. During her day, she let her mind drift to the events of the past twenty-four hours. The storm was exciting, but having her orgasm interrupted left her frustrated. She was glad she finally got a chance to cum that morning. Then there was the arousal she felt as her dad held her in bed, and how she felt his cock grow hard against her bare ass. Also, the realization that he jacked off right next to her. She fantasized about the cum squirting from the head of his cock and painting her big ass.

Her dad for his age was an attractive man. He was relatively fit, and it felt like he was well-endowed. She wanted to see for herself not just feel it pressed against her butt. She wanted to stroke it. She wanted to taste it. She wanted it deep inside her fat cunt! Allyson wanted to do all the things she had read about in dirty stories that she found online, and from videos on porn websites that featured big girls.

"Oh no," she thought. "My dad sexually turns me on!" She could feel herself blushing over the thought as her vagina became moist and tingled. She didn't know what to do, but she thought hard about what she would do tonight.

Later that evening as he finished his dinner, her dad leaned back and said, "That was good!" He continued, "I am going to move some of the clutter out of the extra bedroom. You shouldn't have to share a bed with me. Your window gets replaced tomorrow, and you can have your bedroom back."

Allyson nearly stammered, "No. It's OK. You should relax. Sharing your bed one more night is not an inconvenience."

"Alright," he relented.

Allyson told her dad that she was going to shower and then go straight to bed. He was watching sports programs on ESPN and said he would be up later.

After her shower, she put on a clean nightshirt with no panties and climbed into her father's bed. She tried to doze off, but the anticipation of him coming in was keeping her awake. She was getting aroused thinking of the possibilities and could feel her pussy getting moist. It felt like an hour before the bedroom door opened and her dad quietly moved about as he got himself ready.

He climbed in but settled himself facing the opposite direction with his back to hers.

"Daddy," Allyson said softly. "Will you hold me like you did last night? It made me feel so safe."

He turned over and said, "You're always safe with me, sweetheart," as he nestled up against her.

Allyson shimmied her voluptuous rear end against his crotch hoping to get him going. Her dad tried to move away, but Allyson continued to press against him. Finally, she reached around with her arm to restrict his movement and said, "It's okay Daddy."

"But Allys..." he retorted before she cut him off.

"It's OK," she said again.

He relaxed a bit, and she started to feel his cock grow as she gently rocked her ass against him. His breathing deepened just as it did as he jacked off, and he slowly humped her behind as his hard-on increased.

Allyson was ready to make her next move. She turned over to face him.

"Mmmm, that felt good," she whispered as she lifted her nightshirt exposing her huge breasts. She reached over and took his hand and placed it over her exposed right tit and then lowered her hand to his crotch and gently rubbed his cock through his pajamas. She increased her grip, getting an idea of its girth, and was shocked by how much of her palm it took up. Her hand moved up and down, jacking him off over the fabric of his pants as he started to caress her nipple between his finger and thumb.

"Take them off," she ordered, and he hurriedly did as he continued to face her. Allyson raised herself to a sitting position and removed her top. There was enough light in the room to see the details of her nakedness and her dad was amazed by her hanging breast and her fat belly that flowed down covering her lap.

She reached over and grabbed his cock. It was a good seven inches and thicker than a large cucumber. His erection stood straight up. He was circumcised, and the head of his cock made a nice helmet with the rim of his gland curving upward and meeting at the hole at the tip of his penis where a drop of precum had formed. Allyson stroked his cock as she marveled at it. Her dad's breathing increased as she admired his manhood. Then she leaned over and put it in her mouth tasting the salty drop of precum with the tip of her tongue.

Allyson was not aware of how sexually arousing it was to feel a big hard cock in her mouth, but she felt her nipples get harder and her pussy get wetter. She loved the taste and smell of his cock and hairy crotch. It was hard to get it all in, but she took it as far as she could and periodically had to take it out to get a good breath. When she did, she licked the head and the shaft and worked her way down to his large hairy balls.

"Oh God, I feel like a cock sucking slut from an erotic story!" she thought to herself as her dad moaned in ecstasy. She wanted his cum. She wanted to feel his cock pulse as he shot loads down her throat, but she wanted to do more before she became a true fat cocksucker!

Allyson withdrew from her dad's cock and sat up. He sat up too and faced her.

"Oh Allyson, I want you so bad, but we shouldn't go any farther," he exclaimed as he took in her nakedness. "You are so beautiful. It's hard to resist!"

"I want it, Daddy!" she said as she lay down. "I want it from someone that sees me as sexy. A simple touch from you turns me on so much. I don't get that from boys my age. They just think I'm fat, but when you lay against me and get hard, I know," she trailed off as her hand went down to her pussy and started rubbing hard.

Her dad looked her over as she masturbated. He loved big women and seeing her aggressively pleasuring herself just made him hornier. He couldn't help himself. He turned over and grabbed her tit and put her hard nipple in his mouth and started to suck on it. He rolled his tongue around it and gave it soft bites. Allyson moaned in response.

He left her breast and worked his way down her belly reveling in her fat and deep belly button. Her dad shifted to where he could move down to where her belly met her pubic area. She was shaved smooth, and he felt faint as a wave of arousal hit him from viewing her bald pussy.

Allyson took her two hands and lifted her belly exposing her wet fat cunt. Her clit was the size of a marble and was practically pulsating. He dove his head in between her monstrous thighs and went straight to her pussy using his hard tongue to penetrate her. Then, he went for her clit!

"Daddy!" she yelled as her cunt exploded with a hard stream of orgasmic juices that filled his mouth and splashed all over his face.

He sat up and watched as the liquid streamed out of her making a puddle under her ass.

"That is so fucking hot, baby!" he told her as he moved in between her legs and into the wet sheets.

He spread her legs wide totally exposing her and positioned his cock to penetrate her meaty pussy. He pressed against her hole with his helmet-tipped cock. Even with how wet she was, it took some pushing for her pussy to relent and allow his rock-hard thick cock to slide in deep. His whole crotch pressed against her soaked vulva, and he took a deep breath as he marveled at the feeling of being deep inside her.

Allyson let out a deep moan. Her eyes were looking upward as she felt him deep inside of her. Her breasts drooped to each side of her chest. Her big belly splayed out across her torso, and her tree trunk-sized legs were wrapped around him.

Allyson's dad locked the inside of his elbows with the inside of her knees and lifted her legs even higher, then he started to pump. He humped her slowly at first and as her pussy became accustomed to his girth, he was able to start sliding in and out.

His thrusting increased as his breathing became harder and deeper. Allyson was panting too as he moved harder and faster.

"Fuck me hard, Daddy!" she demanded. "Damn it, fuck me!"

Allyson's legs started to shiver, and spasms rolled through her body. Her dad could feel the wall of her pussy constrict and clench his cock as her orgasm welled up inside her.

"Oh baby, I don't think I can hold off any longer," he said with clenched teeth.

Just then, it felt like her whole body was cramping and her pussy became a vice as she shook in orgasm. She let out a scream.

Her dad felt her pussy seize his cock....
