Krissy had never done anything remotely like this before. It started in the late afternoon when she found herself hanging out with her brother Jim and his two friends Bob and Carmen. One thing led to another and, in exchange for getting to use Bob's car for a day, Krissy stripped for them. I let things get out of hand a bit too quickly, Krissy thought as she knelt in front of her brother and stared at his hard cock. All three of the guys were sitting naked in the living room. Bob and Carmen had just been treated to enough of Krissy's charms to get them off. Now they watch as sister approached brother.
Krissy looked at each of the naked guys. Bob and Carmen were coming around again, cocks reviving, as they appreciated the significance of what she was about to do. Jim looked down at his sister with lust and wonder. He yearned to feel her hot moist mouth on the head of his dick. Who wouldn't? She was the sexiest thing in town. But he wondered what had gotten into her that'd she'd blow him in front of his friends?
Krissy watched another dewdrop form on the tip of Jim's penis. She knew he ached for her. His cock strained with his yearning. She wanted him just as much-and licked her lips.
"Whoa! What's going on?"
The cry came from the doorway. A severe looking woman stood there in a business suit, every bit as shocked as you might think.
All four heads whipped around. Bob was the first to speak. "Hi, Lisa, how ya doin'?" Lisa was Krissy's sister-twin sister, identical twin. She'd been to a job interview.
Jim piped up. "Sorry, sis, you're back early. Must not have gone well."
"On the contrary," Lisa said. "I'm early because it went so well. They hired me on the spot."
Krissy jumped up and hugged her twin. "That's fabulous! Congratulations!" About the same time both realized it was a little odd that Lisa was the only one with clothes on and they parted. Krissy looked down as Lisa's smile turned to a frown.
"What were you about to do?" She looked at her sister questioningly. "What have you done?"
"Well...." And Krissy told the story finishing with, "but I got the car for the whole day."
Bob spoke up. "Actually, Krissy you only got it for..." But Krissy cut him off.
"Bob, I think I earned at least 24 hours, don't you?" And Bob quickly agreed.
Krissy turned back to Lisa. "So are you going to bust us?"
Lisa smiled slyly. "Not if I can watch you suck big brother's cock."
Jim actually blushed. But his cock, having gone flaccid on Lisa entrance, started to spring back to life.
"You'd watch?" Krissy asked suddenly shy. Like most twins she and Lisa were remarkably close and shared most everything with each other. Oh God, this is naughty, thought Krissy. With Lisa watching it would be even naughtier.
Lisa took Krissy's hand and led her over to Jim. The girls knelt side by side in front of him. Lisa whispered to Krissy, "You can tell me the whole story later. Right now, I want to see you do this. I can't believe it."
Taking Jim's big cock in hand, Krissy looked at her sister. "I can't believe it either." Then she opened her mouth and sucked in the head of Jim's hard dick with Lisa looking on from inches away. Krissy's lips spread as her mouth descended along the thick shaft. She hoped Jim enjoyed the sensation of his erection in her tight throat as much as she did. She held him there for a bit.
Jim looked down at his cock engulfed in his sister's throat. Her nose was in his pubic hair. Somewhere in the back of his mind he knew his thoughts should be racing at this bizarre situation but thankfully the erotic waves of sensation going through his body suppressed that. Krissy slowly began to move up and down on his shaft, nearly taking it out of her mouth on each up stroke, then sucking its whole length back in.
Lisa watched the wet cock go in and out of her twin's mouth. It was all too easy for her to imagine herself sucking that dick and how deliciously naughty that would be. She could almost feel it now.
Not wanting to miss a thing Bob and Carmen moved closer. This was just amazing watching Jim's little sister suck his cock. Somehow, having Lisa kneeling there watching up close, still dressed in her business suit made it even more enticing. The boys were stunned as Lisa moved in deftly when Krissy was on her up stroke and took the eager wet penis in her own mouth without losing the rhythm. Krissy smiled at her sister and let her have her way for a while, then took the treat back. Lisa sat up, look at the 3 boys and licked her lips.
And that pushed Jim over the top. Having had both twins suck him, he couldn't last any more. Krissy felt the base of his cock contract and knew what was about to happen. When she pulled away and held her mouth just an inch from the tip of his penis everyone saw the first burst of semen shoot out into her throat. Krissy sucked him deep inside for the next burst but it was more than she expected. As Krissy struggled to swallow Lisa took the ejaculating cock for a quick taste. Recovering quickly, Krissy wanted to finish what she started and took it back. This time when Lisa looked at the boys and licked her lips they saw Jim's come on her tongue.
Bob knelt beside and behind Krissy watching her erotic show. While he watched Jim's cock spasm in her mouth and Krissy's throat swallow again and again, he slipped his hand between Krissy's legs. Her cunt was open and wet. First one then two fingers slipped in easily. Krissy squeezed her pussy on them fiercely and rocked back and forth bringing on her own orgasm. When Bob leaned down and licked her asshole, Krissy went to another level as his tongue teased her little hole.
Eventually they all settled down into an awkward silence as Krissy let Jim's cock slip out of her mouth, Bob took his fingers from Krissy's wet cunt, and everyone found a comfortable place to sit. Neither Bob nor Carmen knew what to do with their nearly bursting, hard dicks. Jim lay back in his chair in a state of erotic oblivion.
