With Alex behind the wheel, the group was making good time on their drive back home from their trip to check out Colorado State University. Brian was in the front passenger seat, busy telling Alex about his exploits at the sorority house. To hear Brian tell it, each girl at the house was aparently an insatiable sex kitten that wanted nothing but to please Brian in every way imagineable, yet Alex was betting that at best, his friend had found one girl who didn’t die of laughter at all his corny pickup lines and MAYBE he got lucky. Once.
Being the middle of January in Colorado, there was snow one the ground as they drove down the highways, so Sam and Alex were sprawled across the back seat - each had her back against a door with their legs up and feet next to the opposite girls’ waist. As they listened to their brothers chatting in the front seat and music softly playing over the car speakers, the girls had their phones out and were texting back and forth, all the while intertwining their legs together and softly caressing each others legs.
This new dynamic between Samantha, Nicole, and Alex had been fun over the last few days, and the girls were taking advantage of their time to play with and tease one another as is so often the case during the unknown of a new romantic relationship.
“So what was your favorite part of the trip?” Sam texted to Nikki
As Nicole read the text, a cute, flustered blush came over her face and she unconciously huddled down into the comforter as she typed out a reply. Samantha couldn’t help but think how adorable Nikki was.
“Ther wer so many to choose from, but if were leaving out the sexy-time’s, id prolly say being snuggled up in between the 2 of u on the bed” replied Nicole
A gentle squeeze of her legs around Samanthas right leg emphasised her words as she watched Samantha read her reply.
With a smirk, Sam glanced over her phone at Nicole and pushed the toes of her right foot firmly, but gently, into Nikki’s upper thighs and against the soft cloth of the pajama bottoms that covered her vagina, causing a slight squeak of surprize from the younger girl.
Blushing, Nikki gave Sam an indignant, scandalized look. Not to be outdone, Nikki stretched her left foot out in a similar manner, trying desperately to reciprocate the pleasant, yet unexpected touch. Being half a foot shorter than Samantha however, Nikki could barely reach Sam’s inner thigh. With a quiet grunt, Nikki stuck her tongue out of the corner of her mouth and wore a face of determined concentration as she shifted lower and desperately stretched her foot forward and out as far as it would go, finally being able to just barely brush the tip of her middle toe against Sams covered vagina. Sam giggled inwardly at the silly situation and look on Nikki’s face.
The two sat quietly and continued their texted conversation the remainder of the ride home, with Nicole all the while caressing Samanthas bear legs, and Sam tenderly applying pressure and caresses to Nikki’s pussy with her foot. They were both clearly smitten with one another, and Nicole had begun firmly pulling Sams foot up tighter, rolling her hips in a soft motion against the foot that was pressed up against her vulva under the covers.
It was late Saturday morning, the day after arriving back at home from CSU, and Brian was getting ready for work at the car dealership when a knock came on the door to their appartment
Opening the front door, Brian saw Tom, his mom’s drug dealer boyfriend, standing there with a bored expression. Letting out a resigned sigh, Brian left the door open knowing that his mom would want Tom to be let inside and went back to his room where he continued his daily routine to prepare for work, but making sure that Nicole’s door was firmly closed. Tom was not the same asshole boyfriend that had attempted to break down Nikki’s door a few years ago, but ever since then Brian had not been able to trust his mothers choice in men.
“Julia” Tom yelled, “I’m here” as he came inside and closed the door loudly behind him.
“Oh hey Tom” Julia said as she came out of her bedroom wearing her typical hip-hugger blue-jeans and plain t-shirt. “You got the stuff?”
Julia had fought an addiction with drugs since she was a teenager, with her longest sober streak being the four years where she had been able to get her life together long enough to put a down payment on the house the family had lived in when they had first met the Konders family, but always ended up falling back into relationships that allowed her to live that horrible lifestyle. Tom was a fairly new relationship, and the kids were grudgingly ok with him most of the time, but he was a meth additct, and when he was high he was unpredictible. A week prior, Brian had purchased an interrior door security bar and showed Nicole how to use it in her bedroom so that she did not have to worry as much about Tom going crazy and breaking down her door like their moms old boyfriend had done.
A few minutes later, Brian made his way from his bedroom to the living room so that he could go to work. He hated drugs and everything that they had done to his family, and couldn’t stand his mother’s taste in men. But he did love his mother and his sister fiercely and was able to overlook the drug problems that Julia had - coming to just accept it as a fact of life. As he made it to the front door, he saw his mom standing with her back to him at the kitchen counter, scruitinizing a fairly large baggy of pills that Tom had put on the counter. Brian rolled his eyes as Tom made eye contact with him and loudly slapped Julias ass, grabbing a handful through her pants as he grinned smugly back at Brian.
“Heading to work mom, see ya” Brian said over his shoulder as he left, not waiting for a response.
Alex and Sam were doing their typical weekend routines with their mom being home and their dad at work. Sam had just gone out for her Yoga class and would be gone for a few hours, so Alex was busy salting the driveway and sidewalk and their mom was inside preparing the roast for dinner that evening.
Alex felt a buzz on his hip, pulled out his phone and saw that Nikki had sent him and Sam a message in the 3-way conversation they shared in their messanger app. He keyed in his password and read the message:
“Hey u 2 ;-D Brian just went 2 work and im booooored, can we do somthing 2day?!”
With a grin, Alex typed back:
“Hey cutie ;-) Sam just went 2 Yoga and I’m busy doing chores. Gotta finish th’ driveway an then laundry and a few other things. Idk what Sam has planned for after Yoga, wait for her reply
By the time he finished his message, he saw that Sam was already answering:
Hi Hun! I’m heading to Yoga and Alex is doing MANLY stuff around the house haha, can I come pik u up after? Like 1:30 ish? We can swing by and grab Alex and go do something 2gether!
A few seconds later, Nicole replied:
I’d LOVE 2 GRAB ALEX!!! <3 ... but seriously that sounds good, I’ll be ready at 1:30! With this, she also sent a selfie of her laying on her bed on her stomach, propped up on a pillow, her eyes peeking over the edge at the camera. Behind her, her feet could be seen up in the air, and a hint of her cute bottom covered by a pair of boyshorts was barely showing.
As Alex read that last message and saw the picture, he felt an involuntary twinge in his pants as he thought about the nubile young girl’s mouth around his penis just a couple days prior. Here eyes were so innocent and beautiful. Thinking about the two girls and all of the fun they had together during the trip, he put his phone back in his pocked, adjusted his pants to be more comfortable around the growing boner he had, and got back to work salting the driveway. He was a responsible member of the family, and he wouldn’t try to come up with excuses for not getting his chores done and still going out with friends when his dad was sure to ask about it later that day.
As he finished detailing the Audi, Brian let his mind wander to the sorority girls that he had partied with back at the university. He had enjoyed his time with his friends and sister for the little amount of time he had actually spent with them during the time away, but the highlight was definitely getting some pussy in the heated pool.
“Man” he muttered to himself, “the things she could do with those legs...”
Brian felt his phone vibrate in his pocket, but management at the dealership was pretty strict with their policies on phone usage during work time and he really didn’t want to deal with another bitchy lecture, so he just continued polishing the dashboard.
When he got back into the service office, Brian grabbed a Gatorade from the cooler and sprawled out in a chair to await the next assignment from his supervisor. Brian worked hard and got his assigned jobs done, but he wasn’t known to be one that went looking for more work to do. He pulled out his phone and thumbed through his notifications
Nicole: Hey, Sam is gonna pick me up and were gonna go do sumthin
He replied:
Have fun. is the asshole still there?
Nicole: Na, mom and him left a few mins ago
Brian had noticed something that seemed different with his sister in the last few days. He considered that perhaps Nicole was developing feelings for Alex, and he wasn’t quite sure how he felt about the idea of his sister going all doe-eyed for his best friend. “Sup slacker” Grace said to Brian, interrupting his thoughts as she came in from the back door.
With a start of surprise, Brian nearly dropped his phone as he sat up when he heard the door open, thinking that it had been his supervisor Dwayne. Upon seeing Grace’s slender form and smiling face, he clicked his phone off, slid it back into his pocket, and resumed his position of relative comfort.
“Yo” Brian replied with a nod and a grin. “What’s shakin?”
With a tired sigh, Grace flopped down onto the couch against the office wall and began flipping through an old “Car and Driver” magazine.
“Nada” She said, “Just slow and boring today, hoping they will cut someone so I can go home early”
“Lazyass” he said with a chuckle
“You’re one to talk” She retorted while giving his posture and position in the chair a significant scan of the eyes over the top of her magazine.
Just then, the shop supervisor came in with a handful of keys “Here ya go guys, the transporter just dropped off 8 new ones and we need them detailed and moved to the lot” he said with a nod to the cars sitting just outside of the building.
With a simultanious sigh, Brian and Grace got up and plucked the keys from the desk where Dwayne had dropped them, ready to go back to work.
Having finished Yoga, Samantha had stopped to get a bear claw from the Dunkin Doughnuts about a block away from Nicole’s house. While waiting in the drive through line, she texted Nicole
Hey Sweetness, I’m about 3 minutes away
Nicole replied almost immediately:
Okie :-D I’ll be ready
Sam took the bag from the waiting hand of the drive-thru attendant and rolled away from the window. As she did, Sam hit play on her phone - Havana by Camila Cabello started playing through the cars speakers and she started to hum along, gyrating to the beat and mouthing the words as she merged into traffic.
Havana, ooh na-na (ay)
Half of my heart is in Havana, ooh-na-na (ay, ay)
He took me back to East Atlanta, na-na-na
Oh, but my heart is in Havana (ay)
There’s somethin’ ‘bout his manners (uh huh)
Havana, ooh na-na
With an unconcious grin, she realized that whenever she was listening to a sexy song lately her mind immediately went to her brother. Their relationship had blossomed over the last few weeks and she found that her feelings toward him had gotten very deep, very quikly. She supposed that was because they had been best friends for most of their lives, and so the transition from friend/brother to lover had seemed easy and natural. She still didn’t like to dwell on the idea of anyone finding out about their unconventional relationship - especially their parents.
Then there was Nicole who was freshly entwined in their taboo afair. The more Sam considered it, the more she liked the idea of Nicole being a part of the relationship. Nicole and Alex could be open about dating each other, and since all three of them had been friends for so long, it would distract any suspicion that might come from Sam and Alex being together so often and neither of them being in relationships.
As the song came to an end, Samantha turned into the seedy apartment complex where Brian and Nicole lived, parking just outside their first-floor door. As Sam glanced down at her phone and started typing a text to Nicole to let her know she had arrived, the apartment door opened and the cute, petite girl came outside.
With her hair up in a ponytail and wearing an oversized “hoody” sweatshirt with a pair of loose sweatpants, Nicole was an adorable sight. Sam was jealous of the younger girls seemingly effortless ability to look good in any outfit, no matter the season. She knew that she herself was considered very attractive, but she always felt the need to wear tight, fashionable clothes in order to be noticed.
The passenger door popped open and Nicole’s head came into view as she bent slightly to see her friend in the drivers seat. Smiling, she said “Hey”, climbed in the car and closed the door, then leaned over to give Sam a quick peck on the cheek. Blushing, Nicole sat back on her side and busied herself fumbling with the seat belt.
Taken a bit by surprise, Sam just grinned at the younger girl who was clearly forcing herself out of her comfort zone in an effort to make their new found relationship seem “normal”.
“Hey yourself” Sam replied as she backed the car out of the parking spot and began navigating back to the main road. As the seatbelt clicked, Sam tossed her phone into Nicole’s lap and said “Want to be the DJ?”
Settling herself in the seat, Nicole picked up the phone and tried to turn it on but was stopped by the passcode. She started to hand it back to Sam, when Sam said “8472”. A bit surprised by this, Nicole looked down at the phone and typed in the numbers to unlock it. “I’ve got nothing that I want to keep a secret from you” Sam said while glancing over at Nicole and giving her a light squeeze on the knee. As Sam started to withdraw her hand, Nicole quickly grabbed it and settled both of their hands in her lap in a posessive manner while thumbing through the playlist that was still up on the phones screen.
The two girls were still figuring out how to behave around one another now that they shared Alex, because both knew that most of the time when two girls had their eye on the same guy, it ended poorly for one or both of them. Most of the time though, three was considered a “crowed” when it came to relationships - not so in this case. True, they still had much to discuss and figure out together, but for now they were both content with just letting things evolve naturally. Afterall, it had worked out rather splendidly when they were checking out the college campus, and neither of them saw a reason why it shouldn’t continue to do so.
Out of the corner of her eye, Sam saw a grin come on Nicole’s face. As she was about to inquire to the cause, a song started playing over the speakers and Sam burst into laughter, giving Nicole an affectionate squeeze of the hand. They Katy Perry song was unexpected but as it came to the first chorus, Nikki gazed out the window and softly sang along while running a finger slowly along the palm of Sam’s hand that she was still holding in her lap.
I kissed a girl and I liked it
The taste of her cherry chapstick
I kissed a girl just to try it
I hope my boyfriend don’t mind it
It felt so wrong
It felt so right
Don’t mean I’m in love tonight
I kissed a girl and I liked it
I liked it
When the song came to an end, Nikki pressed pause on the phone to prevent the next song from automatically starting and asked, “So what’s the plan?”
“Well” Sam replied, “Alex want’s to get his hair cut, so were gonna go to the Park Mall. That’s where his barber is, and I figured we could go do some shopping while he’s making himself all pretty for us”. Both girls smiled at this, and Nicole said “Sounds fun! I gotta be back by around 6 to make dinner for everyone though, is that gonna be a problem?”
“Not at all” Sam said, “It’s only 1:45 now, we have plenty of time” By this point they were already almost back to Sam and Alex’s house since it was only a 5 minute drive from the apartment.
Alex opened the cars back door and got in behind Nicole. “Hey girls” he said, reaching up and giving both of them a quick squeeze on the shoulders then leaning back and buckling his seat belt. “Hey handsome” Sam said, while Nicole replied “Hey Alex” at the same time and then continued, “Do you want to sit up here with Sam?”
“Nah, I’m fine back here, I see you two are bonding anyway” he said, having noticed Nicole holding Sam’s hand in her lap with both of her own.
The gentle squeeze on her shoulder when Alex got in the car sent a shiver down Nicole’s spine - she loved the idea of him touching her, so she enjoyed each time it happened.
Alex adopted a snooty, high-society voice and said to Sam “I say, Chauffeur ... take me to get my hairs cut. And DO be quick about it”
Putting the car in reverse to back out of the driveway, Sam glanced in the rear-view mirror and said to Alex “Don’t make me hurt you”.
As they got on the road headed to the mall, Sam took her left hand off the steering wheel and pulled a bite of her bear claw out of the bag between her legs and stuffed it into her mouth. Alex saw this and said “Yoga and doughnuts, I feel like you’re sending your body mixed messages”
