“Kennedy, did you finish your math homework?” Asher Parsons asked Kennedy Anderson as the two departed the final period, a study hall. The two eighth graders turned left down the hallway towards the school’s back entrance.
“The first four problems were easy,” Kennedy replied. “Did problem thirteen make sense to you?”
“Yeah, that one wasn’t too bad,” Asher replied.
“How? We’re studying the Pythagorean Theorem about right triangles,” Kennedy retorted. “None of the angles in the triangles in problems thirteen or seventeen are ninety degrees. How can we possibly use the theorem if it isn’t a right triangle?”
“It’s not that hard,” Asher said. “Just div ... OH SHIT!” Asher and Kennedy stopped abruptly about a hundred feet short of the school’s back door.
“It wasn’t supposed to rain today,” Kennedy grumped. “The weatherman said it was supposed to be sunny and hit 62 degrees this afternoon. Do you still keep an umbrella in your locker?”
“I took it home the last time it rained,” Asher responded. “I forgot to bring it back to school. Do you have anything in your locker for rain?”
“Nothing.”
“Looks like we’re going to be jogging home today,” Asher remarked. “What choice do we have?” They two had no other choice. Asher’s house was 0.2 miles away and Kennedy’s house was 0.3 miles from Webber Middle School, way too close to be eligible for a bus to pick them up in the morning and take them home in the evening.
Thankfully it was a light rain. The two fourteen-year-olds jogged across the back parking lot of their middle school and took the walking path north towards their homes. The two had not reached the turn-off on the trail that led them west towards home when a flash of lightning nearly blinded them, followed almost immediately by a thunderous peal. The light rain turned to dumping buckets of water instantly.
“Crap! Let’s run,” Asher gasped as he realized he had survived. “That was too close.”
“I’m with you,” Kennedy agreed quickly. The two teens sprinted for shelter at top speed, urged on by two more strikes quickly, as they sought shelter. Another flash/bang echoed through the neighborhood as the kids ran. If anything, that lightning strike hit closer to them than the first.
“Holy shit!” Kennedy gasped. “I’ll get killed before I get home!”
The two were close the “Y” where the walking path split. It was only eighty yards to Asher’s house. Kennedy needed to go left at the split and had almost two tenths of a mile for her to get home.
“Come to my house,” Asher huffed as he ran. “You’ll be safe until the storm lets up.”
“Yeah,” Kennedy acknowledged. The by now soaked teens sprinted across Asher’s backyard. They ran under the overhang of Asher’s house’s deck. Not a second too soon, either. Dime-sized hail started pelting the neighborhood. This seemed like a typical Colorado mid-afternoon thunderstorm. Lots of flashes, booms and things pelting from the sky. Hopefully it would blow through Fort Collins quickly so Kennedy could get home, dry off and warm up.
The soaked kids shivered under the deck as they waited for the storm to pass. As could be expected for a mid-spring thunderstorm, the temperature dropped twenty degrees in the past five minutes.
“Can’t we get inside?” Kennedy asked as she pointed to the door that led inside to the basement.
“I don’t have the key to that door,” Asher replied, nodding sadly. “I only have the back door key, not the one to the basement.” The rain continued to pour down. The size of the hail grew to nickel- then quarter-sized.
The deck sheltered the kids from the worst of the storm, but the gaps between the boards on the deck allowed cold rain to drip on them as they huddled and waited. After five minutes of shivering with no let-up, Asher said, “That’s it. I’ll risk the hail and rain to get inside.”
Asher made his way under the deck to the extension where the steps from the deck came down to the patio outside their back door. He pulled his keys out and made sure he had the right key ready to unlock the door before he dashed across the twenty-five feet of open space through the hail.
“Wait here,” Asher directed as Kennedy followed him. “No reason both of us need to risk the hail. I will come around from the inside and unlock the basement door so you don’t need to risk pummeling by the hail.”
“OK,” Kennedy agreed.
Asher took a big breath and dashed across the open patio. Rain drenched him again. He reached the back door, unlocked it, and stepped inside. Thankfully that only two pieces of hail nailed him, one in the back and a second on his left leg. They hurt like hell when they hit him. He knew they were going to leave welts.
Water puddled at his feet in the family’s mud room. Asher didn’t like it but he had no choice. He stripped off his soaking clothing until he was clad only in wet, clinging compression boxers. He grabbed an old towel off the shelf and tried to dry off a little before heading downstairs to let Kennedy inside.
Asher briefly considered going upstairs to dress before he let Kennedy in but thought better of the idea. Poor Kennedy was outside, soaking wet and shivering. Screw the embarrassment, his friend needed to dry off and warm up ... now!
Asher hurried downstairs to the basement and unlocked the door and opened it. He stood aside to allow Kennedy in. She looked at him in shock and gasped, “Holy shit, Asher. You aren’t wearing anything.”
“I’m wearing boxers,” Asher replied defensively as he blushed.
“Which hide absolutely nothing,” Kennedy said as she stared at his crotch and stepped inside. Thankfully he wasn’t hard. The thin, tight poly material displayed his package, despite covering it. Beet red, Asher turned around to hide his package from his best friend.
Kennedy noted his tight, bubble butt. There was no question, this boy she knew since before pre-school was turning into a hunky teen. Kennedy shut the door and tried to shake off those thoughts. Asher Parsons had been her best friend nearly all her life. Their parents were friends too, going back before either teen was born.
They had played together and been friends since before pre-school. Unlike most elementary school kids, they had stayed friends while most of the boys and girls hung with their own sex to play.
Asher took a couple steps towards the basement stairs and said, “Put your clothes in the dryer. I’ll go upstairs to get dressed and come back with some clothing for you.”
“A big T-shirt of yours?” Kennedy suggested.
“Maybe my brother’s underwear will fit you.”
Eeewww ... no,” Kennedy snipped. “Anyway, Eli’s only ten and at least five or six inches shorter than me. I doubt it would fit.”
“How about a T-shirt and a robe?”
“That works for me,” she agreed. Asher headed upstairs quickly to dry off and get clothes for Kennedy. He grabbed a couple towels from the bathroom on the way to his room. He stripped off his wet boxers and started to dry off.
Damn! He had a naked girl in his basement. The thought of Kennedy down there, undressing and getting naked made him grow an erection in no time at all. This was Kennedy, his best friends for years. How could he think of her like that? He tried to will his boner away as he dried off, to no avail.
Finally, Asher did the only thing that could tame the beast. He jerked off quickly until he exploded with cum. Ropes of cum must have blasted two feet and splatted on his bare wood floor. He cleaned up quickly and got dressed in a T-shirt and sports shorts.
Asher was embarrassed at thinking about a naked Kennedy downstairs while he wacked off. She was his best friend! But still, she was a girl, and developing into a very attractive teenaged girl. She was developing curves in the right places and no way could she be called flat chested like some of the girls in their grade.
He headed downstairs with his robe, a T-shirt and a towel. “Kennedy, I’ll put things for you on the top step and stay upstairs until you’re dressed. Let me know when you’re decent. I’ll come downstairs and get your clothes in the dryer.”
Asher put the clothes on the top step, stepped out of the basement stairs and shut the door. “All clear, Kennedy.”
He heard her come up the steps. “Jesus, Asher. This shirt is huge. I can’t wear this.”
“It’s the smallest shirt I have,” Asher responded. It wasn’t terribly surprising. While most of their lives the two kids had been close in size, until Asher hit his growth spurt last fall. He shot up close to eight inches while Kennedy grew an inch. At 5’-8” and 126 pounds, he towered over his dear friend, who was only 5’-3” and 108 pounds.
Asher waited on the other side of the door while he waited for a heads up from Kennedy. He was surprised when seconds later the door opened, slamming into his backside. Asher jumped out of the way as she came upstairs.
“Um ... um...” Asher stuttered as he stared at Kennedy in his robe. She looked a hell of a lot better in his robe than he did. “Uh, let’s get your wet clothes into the dryer.”
“Silly, I know how to use a dryer,” Kennedy laughed. “They’re already drying.”
“Um ... oh, OK,” Asher responded.
“So, what’s next while we wait?” Kennedy asked. “You up for working on our math homework? I’m stuck on the last couple problems.”
“We could do that,” Asher agreed. The two headed for the kitchen table. As Kennedy passed, Asher caught a glimpse as Kennedy’s robe parted a little. Cleavage! Kennedy didn’t have that a year ago. Asher’s dick stirred as he tried to suppress thoughts he shouldn’t have about his best friend.
They spread their books out on the table and turned to the pages with the assigned math problems for tomorrow. “I am done with problems 1, 3 and 6, no sweat,” Kennedy said. “I get stuck with the next one, number 13.”
“I got that one,” Asher said.
“How?” Kennedy retorted. “The Pythagorean Theorem deals with right triangles. How does that apply to the triangle in problem 13? there aren’t any ninety degree angles in that triangle.”
Problem 13 showed a triangle with a base on the bottom ten wide and five high. The apex of the triangle was offset two from the left end of the triangle. Kennedy was right, there were no 90 degree angles on that triangle.
‘Not a problem,” Asher grinned. “Turn it into two triangles.” Asher sketched the triangle on paper, smiled and then drew a dashed line down from the apex to the base. “Now do you see it?”
“Yeah, I think,” Kennedy acknowledged.
“You have two right triangles,” Asher stated. “A small one with a base of two and a height of five. The second has a base of eight and a height of five. Can you figure out the missing dimensions now?”
“Yeah, I can,” Kennedy agreed sheepishly. “It’s that simple. The third leg of the small triangle is five squared plus two squared. Take the square root and the answer is...” She grabbed a calculator and punched the numbers in. “5.38156...”
“Mr. Moore is nuts on significant figures,” Asher cautioned. “Call it 5.4.”
“Ok, the second one is eight squared plus five squared,” Kennedy said more confidently. “Eighty-nine. So, the square root is 9.433 ... uh, call it 9.4.”
“You got it,” Asher said. “Good job. Now, the area of the triangle?”
“I know that one,” Kennedy replied. “Base times the height divided by two. It’s 25.”
“Write it all down,” Asher said. “You got problem 13. Let’s move on to 17.”
“I think it works the same way,” Kennedy said. She drew the triangle. It had a base of five and a height of five. The apex of the triangle was offset five to the right of the right end of the base, creating an obtuse triangle.
Kennedy sketched in a dashed line from the right end of the base, going perpendicular to the long leg. “Like this?” she asked brightly. She paused moment and added, “No, that’s not it. I don’t know the base or height of either right triangle.”
“You’re close,” Asher stated. “Erase your new line.” He took the pencil and drew a dashed line down from the apex perpendicular to the base, but five to the right. Then he drew another dashed line to the right end of the base of the triangle. “Now you have two right triangles and you know the base and height of each.”
“The one is five by five and the other?”
“The second is ten by 5,” Asher stated as he traced his finger around the outer perimeter of the two triangles.”
“OK, I see it,” Kennedy said. “The bigger leg of the original triangle is the square root of 125 or 11.2. The smaller one is the square root of 50 or 7.2? Right?”
“Exactly right,” Asher grinned. “And the area?”
“Half of five times five,” Kennedy replied. “12.5”
“You got it!”
“I just couldn’t see your trick,” Kennedy said. “Did Mr. Moore talk about this and I missed it?”
“He went over it pretty quickly,” Asher agreed. “Math homework is done.” He glanced out the kitchen window and could see the rain was still pouring down. “Do you want to check and see if your clothes are dry?”
“I set the dryer for thirty-five minutes,” Kennedy replied. “No way are they dry yet.”
“What do you want to do to kill time?” Asher asked. “We could check the Weather Channel and see how much longer the rain is going to last.”
“Sounds good,” Kennedy agreed. The two teens stood. Kennedy gave Asher a tight hug. “Thank you so much for helping me. I was just stuck and lost with those last two problems.”
“Glad to help,” Asher gulped. He could feel the soft pillows of Kennedy’s titties through the thin cloth of the robe she was wearing and the thin material of his T-shirt. He gulped again. His best friend has titties! Asher blushed as he felt is dick stir and harden. Not again!
Kennedy leaned to him and gave him a kiss. Not a friendly kiss on the cheek, a kiss on the lips. A soft sumptuous kiss on the lips. Asher’s dick hardened to a full-on boner.
This kiss was not the first for either fourteen-year-old. Both had been to parties this year were the kids played “Spin the Bottle” and “Seven Minutes in Heaven.” They knew about French kissing and had felt or been felt up before, though neither had kissed the other before this.
The kiss lingered, though neither teen was bold enough to try for tongue. Both kids were dazed as they pulled apart. Asher got another view straight down his robe at Kennedy’s cleavage again. His boner throbbed involuntarily. Neither expected these intense feelings from a thank you hug between buddies.
“Um ... maybe we should check the weather,” Asher finally muttered. “To see how long you’re stuck here.”
“Um ... yeah,” Kennedy agreed quickly.
Asher tried to surreptitiously rearrange his boner so it wasn’t so obvious as they walked to the entertainment room. Kennedy pretended not to notice what he did. She couldn’t help herself though. Asher’s boner had to be way bigger than the only one she had felt in the recent past.
That little boner belonged to Wyatt Finch, a classmate and the lucky guy to get to spend seven minutes in a closet exploring at Ella Samson’s birthday party a couple months earlier. She permitted Wyatt to put a hand up her blouse and feel a titty while she got to slip a hand into his pants and feel his boner. Wyatt’s erection couldn’t have been more than three and a half or four inches long. The bulge in Asher’s shorts looked to be much longer. Of course, Asher was a good six inches taller than Wyatt, so that must factor into it.
Asher plopped down on the couch, grabbing the remote. Kennedy sat down beside him. Asher flicked the TV on and switched to the weather. The radar showed green, yellow, orange and red bands of rain the whole way to Denver and south.
“A whole series of thunderstorms are rolling up along the Rockies this afternoon,” the announcer said. “The National Weather Service has Fort Collins under severe weather alert until 6:30 PM. Expect high winds, heavy rain, localized flooding with a significant chance of hail from these storms.”
“You’re going to be here for a while,” Asher noted. “What do you want to do now? Maybe stream a movie?”
“Sure, that sounds good,” Kennedy agreed. It took the two a couple minutes to decide what to watch. Soon the movie was streaming. Kennedy cuddled up next to Asher as the movie played. They probably saw no more than five minutes when the screen froze. After twenty seconds, the little wheel appeared in the middle of screen, spinning as they waited for the Roku stick to buffer enough of the stream to allow it to continue playing. After about thirty seconds, the screen went dark and a message popped that said, “Internet connection lost. Go to Settings, Internet Connections to restore connection.
“Crap!” Asher groused. He followed the directions and spent a couple minutes trying to restore the internet connection.
“Could it be from the storm?” Kennedy asked.
“Maybe,” Asher admitted. He took out his phone and checked. He had no wifi connection on it either. “Let me see if the cable still works.” Asher switched the TV to cable mode. All the screen showed as a notice, ‘Service Interrupted.’ “That explains what is wrong with the internet.”
“Well ... that sucks.”
“Yeah, what do you want to do?” Asher asked. “Do you have any homework left? I could help you if you want.”
“I finished the rest during study hall back at school,” Kennedy said. “Those two math questions were the last of my homework for today.”
“Well ... that does suck,” Asher grouched. “Stuck inside by the storm and nothing to do.”
“I guess we just hang and talk,” Kennedy offered.
“Wait ... wait, I got it ... maybe,” Asher said suddenly. “It’s going to be a little childish, but it might be better than nothing to watch. We could play one of Eli’s DVDs.” Eli was Asher’s ten-year-old brother.
“DVDs?” Kennedy asked. “You still have a DVD player that works? Ours died years ago when I was little.”
“Yeah, ours still works,” Asher replied. “Our old player died four years ago when Eli was still watching movies on DVD. Dad managed to find a replacement online. He figured it was cheaper than paying Disney every month for streaming.” Asher chuckled. “I can’t imagine why the old player wore out. Between Eli playing it all the time, before that me and before me, Sean. Anyway, it is an option. The movies might be a little childish, but they beat staring at the ceiling until the storms roll through in a few hours.” Sean was Asher’s eighteen-year-old brother, a senior in high school soon to graduate before he headed to University of Colorado down in Boulder.
“What have you got?” Kennedy asked.
Asher went over to the TV stand and opened the door, perusing the titles on the shelf inside. “Uh, Moana, Moana 2, Toy Story 3 & 4, Raya and the Last Dragon, Zootopia and Zootopia 2 and Encanto.”
“I haven’t seen Encanto,” Kennedy said. “I heard it is supposed to be good.”
“I caught bits and pieces of it when Eli watched it,” Asher replied. “Eli didn’t like it that much but it looked kind of interesting to me.”
“Let’s see Encanto,” Kennedy replied. Asher grabbed the DVD and popped the tray on the DVD player open.
“What the hell?” Asher asked as he stared. There was a DVD with no label in the player.
“SDP?” Kennedy noted as she saw the initials written in Sharpie on the otherwise blank DVD. “Something of Sean’s?”
“Probably.”
“Let’s see what is on it,” Kennedy smirked. “It might not be a kid’s DVD.”
“I guess we can check it out,” Asher said. “No way Sean will know if we play this.” Asher pushed the tray closed and used the remote to switch the TV over to display the output from the DVD player. He hit play. The image came up immediately of two older teens sitting on an orange couch in a white room. They were looking at a magazine and laughing about what they read. They weren’t speaking English. The guy was dressed in a ‘wife-beater’, sleeveless T-shirt and jeans. The girl had on short shorts and a thin top. The outfit showed lots of leg and cleavage. Both teens were barefoot. The guy had his arm around the girl’s shoulders.
“This isn’t a kid’s movie, that’s for sure,” Kennedy noted.
“Should I let it play?”
“Sure, let’s see what this is,” Kennedy replied. The two teens sat back down on couch, cuddled as they had been before the storm knocked out the internet. Asher slipped his arm over Kennedy’s shoulders imitating the action on screen unconsciously.
The first couple minutes of the video were just to two teens talking in some incomprehensible eastern European language while they giggled and looked at the magazine. Things started to escalate after that. The guy slipped down one of the straps holding the girl’s top up and rubbed his hand across the top of her right titty. Soon the left strap slipped down to. The guy rubbed her belly first over her blouse and then slid his hand under the hem and rubbed her bare belly and a little higher, almost to her titties. The girl just smiled and giggled as the guy rubbed and tickled her.
The guy’s hand pulled out and went to the top of her blouse, tugging at it right at her cleavage. Less than thirty seconds of tugging had pulled the blouse down, exposing her nipples.
“Holy shit!” Kennedy gasped. “This is a porno.”
“I can stop it,” Asher offered as he stared at the opening in his robe, that displayed an enticing bit of Kennedy’s cleavage.
“No, don’t.”
The two teens sat and watched, entranced. Soon the blouse was down, exposing all of her titties while the two teens on screen began tongue kissing. There was not question they were Frenching. The exchange of tongues was graphic on the video. They guy’s hand went to one of the exposed breasts and he felt her up as the two continued kissing.
Asher’s dick, which had subsided somewhat during the internet outage, grew to full hard-on again. Kennedy shuddered involuntarily and eyed the prominent bulge in Asher’s shorts. Maybe they should stop this video, she wondered. No, it was too interesting. Watching this made her feel all tingly. They should stop. No ... they shouldn’t.
The teens on screen continued kissing for a couple minutes more. The guy continued feeling the girl’s titties as she writhed and giggled in anticipation. “Asher?” Kennedy murmured as she turned her head towards her friend. Neither teen had realized, but their heads had tilted towards each other as they watched. Asher turned to find Kennedy’s face an inch from his own.
The two teens stared into each other’s eyes for moments before Asher twisted his head and kissed Kennedy. The kiss lingered. It had intent, it was not a casual thank you kiss. Asher slipped his tongue out between his lips, expecting to feel Kennedy’s lips. Instead, he felt her tongue, her soft, moist tongue. The two shuddered as the felt the energy zap them.
They did not recoil. Both teens had French kissed before, though you could not call their experience extensive. Still, they knew how to and why teens since time immemorial had done this. Asher and Kennedy were soon lost in a swirl of kisses and tongue sharing.
When the two were forced to pause to catch their breath, they saw the scene on TV had changed radically. The girl’s blouse was bunched around her waist while her shorts were on the floor. The guy’s hand cupped her womanhood as he suckled at one of her breasts.
