This story is set in the fictional Free Use world I have created for all of my stories. Below is what could be a ordinary occurrence in that world with a misunderstanding between two good friends. Enjoy!

Betrayal by Best Friend

The tears in Katie’s eyes clouded her vision. She had just gotten home when she had gotten the message from a friend. Her best friend Karlie was betraying her. Despite the upbeat look of her university cheerleading uniform, her emotions flooded her brain and she simply wanted to be with her family. Specifically, she wanted to be with her stepdad, Mark. Mark was all the time supportive and understanding. Katie calmed down enough to stop crying and brushed the light brown hair from her green eyes. She tucked it behind her ear and entered her house.

Katie moved towards the house’s interior where she could hear Mark grunting. She figured he was working out and that was usually a good time to talk with him. She rounded the corner to where the sounds were coming from and saw her best friend Karlie with her head buried in Mark’s crotch. He had his entire cock down her throat. Mark was standing over Karlie’s blonde hair and bucking his hips into Katie’s best friend’s face. Karlie’s cheer top was lying on the floor, but she was still wearing the same skirt as Katie although she had it flipped up so she could rub her bald pussy with the spit that slid down from her tits to her cunt. The pair hadn’t noticed Katie even come in the room. Katie was frozen for a moment as well, not expecting the sight of her best friend being face fucked by her stepdad to greet her.

The emotions came flooding back instantly seeing the embodiment of the betrayal before her eyes. Anger took over as she watched Karlie’s blond ringlets stream through her stepdad’s fingers. Standing with his back to her, Mark had no idea Katie was there.

“What the fuck?!? How could you betray me like this?” yelled Katie to her best friend. Mark was startled and confusedly turned to furrow his brow at Katie as he stopped humping Karlie’s face. Karlie too, leaned to the side as she let a large amount of spit fall down her chin and onto her perky c-cup breasts. She saw Katie standing in the doorway seething in anger.

“What’s wrong with you? I’m just giving your stepdad a blowjob. I’ve done it dozens of times,” Karlie calmly stated before centering herself with Mark’s hard and wet member in front of her face again and then resuming sucking on his cock. It only served to incense Katie more. She marched over to the side of the fellatio fun and accusingly pointed at her best friend.

“You are seriously going to sit there and blow my stepdad and pretend you have no idea what’s wrong?” Katie raged.

“Katie, you are shaking with rage. What kind of stress is this?” Mark asked while Karlie quickly switched to sucking his balls and stroking his cockhead.

“Because my best friend has decided to hurt me in one of the worst ways possible,” whined Katie as Karlie had returned to sucking Mark’s cock properly.

“I think there could be a misunderstanding here,” Mark offered as Karlie started twisting her head and hands in opposite directions before spitting on Mark’s cock and then bobbing again. Katie’s anger flashed at Mark now but the mere suggestion of possibly being slightly wrong paused Katie briefly. In that brief pause Karlie pulled her lips from Mark’s cock with an audibly wet pop.

“It might be easier to talk if I ride you,” Katie said looking up at Mark and stroking his shaft.

“Good idea,” Mark agreed and sat on the couch. He slouched down to provide a less inclined base for Karlie.

“Are we going to ignore the obvious and continued betrayal by my best friend?” asked Katie incredulously.

Karlie was in between Mark’s legs and then leaned back to use her hands on his chest. He held her hips as she lifted her feet onto his knees to ride him reverse cowgirl style so she could face Katie.

“Give me a second, Katie,” Karlie huffed as she reached under her body to discover and guide Mark’s rock hard and throbbing cock into her warm depths. “There…mmm…” she hummed as the head slid in and she sank her hips down letting his spear part her soft flesh. Beginning a steady up and down, riding Katie’s stepdad’s dick up her sweet pussy.

“I…huh…haven’t…huh…betrayed…huh…you,” Karlie huffed riding Mark.

“I have all the evidence right here!” Katie protested.

“Oh fuck this is a great cock,” Karlie moaned quickly shuddering in orgasm.

“Stop ignoring the obvious. You are the worst friend,” Katie spat at Karlie.

“Why do you think I beat you here?” Karlie asked stopping her riding. Mark took her inaction as his go signal and started rocketing his cock up into Karlie. “Ohhh fuuuuck!” she moaned throwing her head back.

“Cause you wanted to rub it in my face!” Katie accused. “While our assistant coach selected Maria and I to give him his usual rimjob and blowjob after practice, I saw you talking to Coach Stenson while you pushed Ashley’s head down on his cock. You used her mouth and probably your dirty words to steal being cheer captain from me. I told you for the last two years I have wanted, dreamed about, and practiced to be cheer captain! And you stole it from me,” Katie accused with sobbing tears rolling down her reddened cheeks.

Mark had stopped pumping and Karlie sank her hips down to bury his cock inside her pussy.

“Hold on, he’s cumming,” Karlie said to her best friend. Karlie leaned forward to watch Mark’s balls tighten and his cock pulse as she felt the first ropes of cum fill her cunt. “That’s it. Yeah baby. Fill this tight, little, cheerleader pussy with your cum. Pump it deep inside me,” Karlie cooed as she gyrated her hips slightly to help milk the last ropes. Even Katie’s tear streaked face was staring as the pulsing cock of her stepfather filled her best friend. “It feels so good when a cock creams my tight little holes,” Karlie told Mark with a wiggle of her hips.

Once Mark finished, Karlie put her feet on the ground and lifted off of his cock. She took a few steps to her best friend. Cum freely ran down her thighs as she approached Katie, still blubbering and holding her own hands. Karlie got close and wrapped Katie in an embrace, pressing her tits against her friend’s chest.

“Coach Stenson called me into the office to ask if I wanted to be co-captains with you of the cheer team. I was pushing on Ashley’s head to force her deeper on Coach’s cock to be polite. How rude would it have been of me not to enhance Coach’s blowjob?” Katie explained to Karlie.

“Really?” Katie questioned.

“Yes. Coach said he would text you later,” Karlie said returning to Mark to suckle the cum off his cock. As if on cue, Katie’s phone dinged. Sure enough it was Coach Stenson naming her and Karlie co-captains of the university cheerleading squad. He wanted his new captains to report an hour before practice to learn the new pre-practice double blowjob routine. Katie’s heart leapt in relief and then sank at the realization of what she had accused her best friend of.

“You good, girlfriend?” Karlie asked Katie.

“Yeah, yeah, I’m so sorry,” Katie mumbled looking up to see Karlie leading her stepdad by the hand to the stairs.

“Hey where are you going?” Katie called. Karlie stopped and turned to answer.

“We thought you were going to take longer so Mark and I had this whole plan. After pumping a load in my pussy, I asked him if he could film me drinking his piss. After that he wanted to fuck my ass in the warm shower. Kinda be a waste of plans to not complete those things,” Karlie told her friend before turning to continue leading Katie’s stepdad upstairs.

Katie was left alone with her thoughts and feelings. Trying to contain her elation but also understand how to make up to Katie and Mark. She felt alone and vulnerable and foolish at that moment.

“Hey Katie!” Mark called from upstairs. “Do you want to join us?” her stepdad asked. “I’ll fuck your ass too and Karlie says you can join her in the video if you want.”

Katie practically leapt out of her seat. “Yeah!” she called up as she scurried upstairs. “I’m so lucky to have a stepdad who gets me,” she wondered to herself as she hastily ascended the stairs.
