Sara picked up Richard from high school and immediately started playing with his cock even before they got out of the school parking lot. She was pretty sure a couple of girls they passed saw her jacking off her brother while leaving the parking lot. At least, they had shocked faces when she looked in the rear view mirror. Richard got his hand under her skirt, only to find she wasn't wearing any panties either, so he stuck two fingers deep into his sister's cunt and then brought them to her lips, where she hungrily licked off her own juices!
"Damn, sis! Pull the car over! I've been so horny all day! First mom sucks me, then you suck me and make me cum, then I eat your pussy! I've just got to fuck you now!" exclaimed Richard.
"I want us to fuck too, Richie. But I need birth control pills and you don't have any condoms. But I am pulling over so we can pleasure each other. Have you thought about what you are going to do about mom?" asked Sara, pulling into the mall parking lot.
"Isn't this a bit public?" asked Richard.
"Sure is!" replied Sara. "That makes it all the more exciting! Tell me what you want to do with mom while I suck your cock!"
Sara opened all the windows, took off her skirt, and then bent over her brother, sucking his cock as far down her throat as she could. She could feel it pulsing against her tonsils and the back of her throat as she fought the urge to gag. She got into a rhythm and put her ass in the window where anyone could see her shaved pussy as she bobbed up and down on her brother.
"Damn, sis! You're getting better at this! Umph! I think I am going to wait up for mom, pretending to be asleep when she comes into my room tonight. Then surprise her somehow and confront her. Come on, sis! Let me put it in your pussy for a little bit!"
"Okay, but don't cum in me. Get out of the car and fuck me through the window."
Richard quickly pulled up his pants and quickly went around the car to the driver side window. His sister's pussy was right on the edge of the car door. Pulling out his cock, he slammed it into his sister's tight cunt, making her grunt hard as he thrust fast into her, over and over again! "Damn sis! Your cunt is as tight as I thought it would be! I'm gonna cum soon!" he said.
"Get back in the car and I'll finish you off, Richie! You can't cum in me!"
Richard pulled out of his sister's sweet hot pussy and got back in the car. Sara engulfed his cock, almost all the way to his balls, as he started cumming hard! Richard spurted ropes of hot cum down his sister's throat for the second time! It was so fantastic! He looked at the car in front of him and two girls were in the front seat watching him! They must have seen him fucking his sister, and heard them talking, too. But they were just sitting there watching and smiling. They waved and blew kisses!
"Now eat my pussy, Richie! Do it from outside the car!" said Sara. Richard got his pants back up, got out of the car and went around to the driver side. He knelt down and stuck his head between his sister's ass cheeks and started tonguing his sister's clit and pussy! He tongue fucked her as she moaned loudly into the passenger side of the car. He looked over at the two girls in the other car and they were now kissing each other! Fuck! Lesbians watching me eat out my sister! He plunged his tongue into his sister as far as he could! Then he reached in, grabbed her clit and pulled hard! Sara screamed and covered his face with her juices as she came and came! He licked and licked up all he could as Sara came and finally calmed down, resting her ass cheeks on the car window sill.
"Damn Richie! That was fucking awesome!" she said. "Now get back into the car. We need to get home."
Sara and Richard's mom was sleeping when they got home from school. Their father Rodger was still at work.
Sara crept into her parent's bedroom and slowly pulled down the covers, revealing her mom, who she knew slept nude. She had very nice tits for her age, thought Sara. She thought about kissing them, but decided not to do so at this time. Instead, she decided to get ready to tease her daddy some more that evening.
