*****
Sam was laid up in her twin-sized bed staring at the popcorn ceiling that resembled a white washed galaxy. Her head was full of the most vivid memories that took place a few days ago, on her birthday. She could barely believe herself. She was fighting to come to terms with what she had done with Sandy.
"Incest..." She thought deeply to herself.
The word echoed in her head. It bounced in between her ears like a rubber ball. She rolled over on her side and began staring blankly at the wall parallel to her bed. Still deep in thought she started to remember the feeling of her sister's hot wet body on hers. She felt a tingling on the surface of her body, on every spot Sandra had touched. Slowly, she began to become aroused by her memories.
Sandy had gone to stay with a friend for a few days. Sam was left to fester in thoughts and memories of that amazing morning, by herself. Tossing and turning in bed, Sam wound up on her back once more. She slid her right hand along the fabric of her t-shirt until she reached its end, and she touched her mound. She felt a slight prickle under her finger-tips. She wondered how long before she would have to shave again, and she hoped Sandy would be the one to do it for her.
Thoughts of shaving alone aroused her even more. She began to edge her fingers towards her chunky vaginal lips, and she began to lightly tug and separate them. Sam's powerful middle finger landed on her semi-wet clitoral hood. She closed her eyes and imagined Sandra leaning over her, teasing her with stimulation. Her light-brown areola began to shrink, and wrinkle like wet finger tips. Before long her larger nipples were erect and making bold imprints of themselves on her white t-shirt.
Sam began to rub her pink knot round, and round. She went slowly at first. She was so sensitive she could feel the ridges of her finger tips as they glossed over her clit. Thoughts of Sandy were putting her in a frenzy. Sandra had unlocked something inside of her sister. Something which Sandy now seemed, unknowingly, to control. These erotic thoughts were bringing the devilish side of Sam to life in this small bed with no audience.
Sam's knees were now acres apart from one another. Her satin sheets were discarded to the floor and a cool gust of wind from the ambient air tickled her intimacy. She slid her fingers with ease towards her oozing opening. The sounds of their impact on her tight box could be heard through echoes in the room. She slid in one finger, then two. Before long she was passed her second knuckle and penetrating herself deeper than she had ever before.
She began to feel a rush from a nearing orgasm. Her head grew hot as did her groin. She could feel her heart pounding like nearing death in her throat. Her red pedicured toes curled on to her bed sheets, gripping them like a primate. Her soft lips separated and sounds mimicking tiny cries of pain, or pleasure, began to escape her throat. Her eyes saw the back of her head, and in darkness she came. Her fingers began to make random jolts in and out of her wet slit. Her arm felt nearly paralyzed as her nerves tried to catch up with her rebooting brain. She was coming down off of the high she built herself up to.
Before Sam could relax herself her bedroom door flung open. The immediate sound of jingling purses that were hanging from the inside door knob greatly startled her. She threw a small pillow over her beet red vagina.
"Hey hot stuff hope I'm not interrupting anything," Sandy said with a smirk on her face, and an aged duffel bag in one hand.
"Christ don't you knock? I was having some alone time. I thought you were mom, or Mark," Sam said while pushing her self up and resting on her head board.
"I live here too you know," Sandy said sarcastically.
Sandy tossed her bag on top of her own bed and sat at the foot of it.
"So how was Karen's?"
"Fine she just dyed my hair and straightened it," Sandy said.
"Looks cute I like the tinge of blue in the highlights," Sam complimented.
Sandy said while unpacking her bag in to her bedside dresser, "Thanks, wasn't sure about the color, but I'm feelin' it now."
The empty space in the door frame became occupied by a large figure in the corner of Sam's eye.
"Oh hey mom," Sam said cheerfully.
Mom was a larger woman. She stood about 5'10'' and about 230lbs. After having two children and a desk job, time had begun to take a toll, but she had such natural beauty even in her plump state she was beautiful. She had jet black hair that seemed more dense than steel. She had wide hips that connected a very round very large butt with thighs to match. Above her belly were two enormous size F breast. She had a cute set of plump, full lips that were painted dark red. Her eyes were a beautiful brown. She always took care of her make up which enhanced her natural features.
"Your uncle James wanted to know if you girls wanted to stay the night. He and aunt Kim just finished the pool," She said while stepping in to the room with a small basket of folded laundry.
"Yeah that sounds awesome!" Sandy exclaimed.
"Yeah for sure, will aunt Kim be there too?" Sam asked.
"Yes they're going to BBQ tonight. Me and Mark were going to come too, but we want to take a date night," Mom said as she lined the dresser drawers with freshly folded clothes.
Sandy reached in to her drawer and pulled out a bright orange bikini top, and then a small thong style pair of bottoms in the same color. As Sam watched her sister she began to feel anxious thinking of what swim suit she would wear. She tried to allow the new found side of her to "hush" her anxiety away. She knew that she could either wear a pair of gym shorts and a shirt like always, or she could use the two piece she received as a gift almost a year ago.
Mom made her way with an empty basket in hand towards the laundry room shutting the door behind her. Sam stood and walked over to her own dresser. She slid the top drawer open to discover her brand new black two piece that still had the tags on it. The top had two large triangular shapes that were ruffled with similar bottoms.
"You'll look great in that," Sandy said in a sexy whisper.
Sam's skin began to tingle at the whispers of her sister's voice. They reminded her of the soft words Sandy had spoken while in between her legs, in the bathroom. The girls packed their bags and headed for the door.
They went out to Sandy's car and threw their bags in the trunk. The little VW Golf had made them both some great memories during their time in high school. Sam sat in the passenger seat and began to look out the window through the flaking window tint, and admired the small garden of flowers near their mailbox. She waited for the cool blast of A/C to distract her from the hot Florida summer air.
