Laura woke once again to the feeling of her cock being erect between her legs. What surprised her was the large tent that was formed as it stood upright under her sheet. When she pulled the sheet down it revealed the engorged member had grown double in size where it had been perhaps just shy of 3 inches it now was 6 or 7 inches in length making a proud presence above your pussy lips. The moderate cock stood upright dribbling a small bead of precum at the head demanding to be soothed once again. Laura reached down and her small hand only wrapped partially around its girth now leaving a bit of a space between thumb and her fingers. Laura jolted with a bit of pleasure again but she noticed the smell of her precum wasn't as mind warping perhaps, she had gotten used to the smell or her mind had gained control of at least her urges.
In fact, the aroma was rather pleasant if anything at all. Her new desires were getting the upper hand in the short time since the carnal act between her mother and herself. But Laura tried to push these feelings down realizing that it may be easier to ignore her new erotic habits for longer periods of time rather than indulge at once. For some reason this new awakening felt like something bad. In some sense, it was as if her mind was trying to protect itself from being caught by its carnal behavior and warned her that if she followed those urges then it may never end. She pushed those disturbing thoughts away when she decided it was time to shower and stopped mindlessly play with her cock getting up out of her bed and heading down the hall to the bathroom with a set of clean clothes for afterwards. Setting a pair of black boy-shorts, matching bra, a pair of yoga pants since here only large pair of sweats were still in the wash and a baggy oversized sweater to the side Laura jumped into the shower. Laura washed herself thoroughly trying to get the smell of dried cum and the constant aroma off herself. Laura also tried to do her best to not play with her longer cock but she kept getting distracted by its constant bouncing erect presence.
While Laura showered, unbeknownst to her, her mother opened the bathroom door a crack and began to watch her daughter completely naked washing herself in the shower. Her mother couldn't help herself but took notice of how hard Laura's cock looked at first glance, but was surprised to see it had gotten larger than before. It appeared to have doubled in size from this morning and was throbbing even more profusely than before as if it was already ready to fire another load for her. Laura's mother felt her insides twirl in desire thinking about the encounter in the car. She continued to watch for a while before slowly begin to touch herself.
Laura knew that she needed to make her cock go down before she got out of the shower and dressed. Laura stopped absentmindedly playing with and began to move her hand up and down her new length in earnest. The pleasure was just the same as the last time she had done this but her mind was still clear she was able to focus on the pleasure. Laura leaned against shower's wall bracing as one hand focused on adjust the grip as more and more fluid leaked out the head of her cock and the other darted to a nipple or to her lips of her vagina to further build on the pleasure she was experiencing. But there was no sign of any climax occurring, nothing happened as the pleasure kept build and building.
A flash went across her vision as she saw someone in the mirror as she peered over at her own shapely nude form with cock in hand, she saw her mother's face peering through a crack in the bathroom door with an almost pained expression. Laura froze for a second as she felt a light warm buzzing sensation building in her groin. Laura gasped as her orgasm rushed to the forefront as she fell backwards sliding into the cool water of the shower feeling her orgasm pour from the head of her cock. Her hands came to rest on the shower walls watching the eruption in the mirror until it stopped her breath hitched in her throat, finally, after a moment she lowered her head below the surface gasping for air as she recovered and found herself watching the large pool of cum rinse down the drain. When Laura looked up, she saw that the bathroom door was closed again. Laura stood under the stream of the shower head for few more minutes watching her moderate cock soften to rest neatly over her pussy.
Finally, she finished her shower. While drying herself, Laura did a thorough job cleaning up the slight scent left behind on her skin. Laura put on the new clothes taking the chance to inspect them to make sure they were not too tight in the crotch. Unfortunately, her new growth had made her bulge very noticeable in tight form fitting yoga pants but she was able to hide her crotch completely if she lowered her shoulders and the baggy sweater a bit.
Laura mind was filled with the image of her mother peeping on her with what is thought of as an orgasm on her face. Even though Laura thought it would make her feel uncomfortable and somewhat dirty she quickly realized that it was not. It was the same thing she liked so much about the experience in the car with her mom: no guilt or hesitation; complete uninhibited excitement with a brief intense moment of pleasure for both. Her thoughts then turned to daydreams of possible future sexual encounters with her mother. They were exciting yet realistic scenarios that involved Laura exploring herself sexually with her mother while imagining that they both enjoyed it as well. Laura soon was on her way back to her room, confident she would find her mother waiting for her there, despite all her optimistic hope she opened her bedroom door to an empty room except for a folded pile of clean bedsheets and her clothes that she had put in the wash.
Laura quietly made her bed attempting to shift her internal thoughts to less sexual ideas as the previous ones were begin to make her yoga pants tight. This is when she heard the garage door open signaling the arrival of her father and older sister. Laura's father was a successful real estate developer who owned several properties throughout town. He was tall man but had developed a bit of gut after years of working long hours and sedentary lifestyle at home but some of Laura's friends found him still attractive calling him a DILF with the dad bod. Laura's older sister, Kim, was working with her father trying to learn the family business, while Laura was the petite slim but curvy cheerleader, Kim was the tall Amazonian figure who seemed to have got the best genes of both their parents. Kim was just shy of 6 foot and had breasts that had caused her back issues growing up until she got custom made bra to help.
Laura felt a wave panic rise stifling the rising lust she was experience. What would her father and sister think when they found out about whatever had happened to her! Laura finished making her bed and stowed her clean clothes in her dresser before becoming locked in panic in flight or fight amount of stress. Laura's mother knocked softly on her door before opening it to say "Sweety? Dinner is ready but I can understand if you aren't hungry and don't want to eat with us... Your father said that he did want you to join us for movie night though he said he wanted to make it celebration of your graduation. I told him we tried to celebrate earlier today but we had an "accident" on out trip and had to end it early" Laura's mother gave understanding look before continuing " I'll just bring you a plate and when it's time for movie night we can share the loveseat instead of you and your sister."
Laura just nodded back with a sort of death stare at the wall. When her mother came back about ten minutes later with a plate of food she was still sitting where she had been. It was only when the smell of food wafted to her that broke out of her comatose state and the hunger finally kicked in. Laura cleaned the plate of food in minutes eating more than what she usually did.
After Laura ate, she spent the few hours between dinner and movie night's start time to research her bodily issues. Nothing turned up decent results but she did learn somethings about what possibly had happened to her body beyond the physical presence of a male sex organ. She learned that certain species can produce mind altering chemicals that can affect those around them changing them to for number of things from bees to command each other to certain microscopes using chemicals to turn invisible to predators. Laura began to wonder if the constant pleasant aroma she seemed to now emit was something like these. Her further research was interrupted once again by the soft knock of her mother.
Her mother opened the door for herself, she had changed into a pair of lavender sleeping pajamas that were almost a bit sheer allowing Laura to see the outline of her mother's nipples through the top due to the worn fabric. Laura immediately turned her head away trying to reduce the sudden flush of lust in her body.
"Laura if we hurry Kim and your father are still getting ready and we can get the love seat with no arguments" said Laura's mother grabbing her hand and pulling her to the entertainment room.
When they got to the room Laura's mother sat Laura to the far side of the tv putting her on the side that would keep her slightly behind where her father and sister would be sitting. When the rest of the family arrived about 15 minutes later everyone settled down. Her sister was dressed in an oversized t-shirt and shorts that were loose and comfortable while her father had only managed to just take off his belt and unbutton his dress shirt.
"Congrats my sweetie pie!" her father said lifting his hands up for a standing hug "come here!"
