Axl (21 years old) groaned and banged his head against the steering wheel. "Seriously? Of all the times"
His girlfriend Lexi (19 years old) rubbed his arm reassuringly. "It's OK Axl. We'll figure something out."
Sue (19 years old), Axl's sister, who had been quietly reading in the backseat, stated "What's going on? Why did we stop?"
"The car broke down, Sue. We're stranded." Axl was frustrated.
The three of them sat in silence for a bit, staring out at the deserted highway. They had been driving home from a college visit for Axl and Sue, and now it seemed they would be spending the night somewhere other then their own beds.
Lexi spoke up. "There's a hotel just up the road. We can go there and figure out what to do in the morning."
Axl nodded. "Yeah, that sounds like a plan."
The three of them grabbed their bags and trudged up the road to the hotel. As they walked, Sue chattered excitedly about the adventure they were having. Axl and Lexi exchanged a amused glance - only Sue would find the bright side of a broken-down car.
When they arrived at the hotel, Axl checked them into a room with two beds. Lexi flopped down onto one of the beds, exhausted. "I'm so glad we're not sleeping in the car," she said, closing her eyes.
Sue went over to the window, pulling back the curtains to look out at the parking lot. "Wow, look at all the cars! I bet we're the only people here with a broken down car."
Axl shook his head. "You're probably right, Sue."
As the night wore on, the three of them settled into a comfortable routine. Lexi ordered pizza from the hotel's restaurant, and they spent the evening eating, laughing, and watching TV.
Sue suddenly piped up, "Hey, can we have a slumber party?"
Axl raised an eyebrow. "A slumber party? Sue, we're not exactly kids anymore."
But Sue was determined "Come on, it'll be fun! We can stay up late, tell ghost stories, and giggle."
Lexi grinned mischievously. "I'm in. How about you, Axl?"
Axl sighed. "Fine. But just for a little while, and no scary stories Sue."
The three of them settled in for their impromptu slumber party, chatting and laughing together.
Sue snuggled into bed beside Lexi. Axl turned off the TV and climbed into the other bed, feeling grateful for this little adventure with his sister and girlfriend.
As he drifted off to sleep, he could hear Sue's soft giggles and Lexi's gentle whispers. This might not have been the night he had planned, but had turned out to be special nonetheless.
Axl woke up with a familiar sensation, his beautiful petite girlfriend with her mouth sucking his cock.
"Mmmm..." he groaned.
With his cock still in her mouth, Lexi attempted to shush him, which reminded him that Sue was in the room. Lexi grinned devilishly, and Axl quickly looked over to see Sue sound asleep in the next bed.
Lexi quietly moved up to Axl's ear. "I couldn't wait any longer, I need sex." Lexi was a bit spoilt, and Axl was happy to oblige. "It was either you or Sue." She said seductively.
This made Axl's cock twitch, much to his own surprise. He had never ever thought of his sister in a sexual way, even as she developed into a beautiful woman.
Lexi, complete nude, sat her shaven pussy on Axl's face. Axl gladly lapped her up, causing Lexi to gasp, as she went back to work on his cock in the 69 position.
Lexi's gasp caused Sue to stir, and she - still asleep - moved in her bed. As Axl ate his girlfriend out, he couldn't get the thought of Sue out his head, and over Lexi's ass, he could just make out Sue. Her blankets had fallen off, and he could see her torso, realising her nightie had pulled down slightly, and the tip of her nipple could be seen.
Axl felt ashamed but so turned on by his sister, and started to cum into Lexi's mouth. This in turn sent Lexi over the edge, as she silently orgasmed over Axl's face while his cum dripped out of her mouth.
Sue's eye suddenly opened, and she saw her best friend climb off her brother's face. To her credit, she didn't make a sound, but blushed furiously, particularly when she saw her brother's still fully erect cock silhouetted against the room.
Lexi giggled, and Sue saw her cute little ass dash to the bathroom. She quickly closed her eyes, her heart racing at what she just saw, and tried to get back to sleep.

Sue didn't sleep well that night. And early in the morning, she got out of her bed, careful not to disturb Lexi, who had returned to their bed, and went to shower.
Sue knew she was 19, but she always felt embarrassed about sex. In the bathroom, all she could think about was the sight of her brother's cock, and Lexi's ass. Sue disrobed, and looked at herself in the mirror, trying to be objective.
She noticed her nipples were very hard, and gently caressed them, which sent a pleasure chill through her body. She gasped, as she took stock of the woman she had become. Firm breasts, tight stomach. She was sexy right?
