"W-what?" I said in surprise.
"I said," my sister explained as she spread her legs and showed me her pantiless pussy in the backseat of Mom's car, "Eat my pussy on the way to school. Please?" She begged.
I glanced back at our neighbor but her back was to us and then looked back to my sister and shrugged, "I love the taste of your pussy," I told her as I got down of the floor of the car and dove right in. I immediately start lapping Barbie's puss with not a care in the world. I just loved the flavor of my sister's cum so much, I would say I probably loved licking her pussy almost as much as my mom liked sucking my cock.
"Oh shit, ooohhh fffuuuck, ooooohhhhh shhiiiittt!' Barbie started moaning obscenities, louder and louder as I continued to assault her pussy with my tongue. I really wanted her to cum, I wasn't too concerned about her making noise, even though most of our neighbors were waking up right then and coming out of there houses to go to either work or school.
After about a minute or so of me lovingly lapping Barb's cunt, Mom got in the car, freshly showered. As she sat and adjusted the mirror she saw what we were up to in the back, "Come on, Barb, what did I just say?"
"What? You said, oh fuck yeah, oral sex was okay." Barb pointed out between moan as I ate her pussy, "Besides, how is this any different than what you were doing in the dining room just now!"
I was too busy eating Barb's cunt to really know how Mom reacted to that, but when the car started moving without anyone saying anything to each other, I knew Mom was ignoring us now so she could drive. Though it felt like we were bobbing and weaving a little bit so maybe she had her eyes in the mirror so she could watch as I went down on my sister in the backseat. I ate her pussy like there was no tomorrow.
But then Barbie grabbed my head and shouted "Keep going! Don't you dare stop! FUCK I'M CUUUUMMMMMING!" She moaned and I wondered if any other cars were nearby because if they were close enough there was no way they didn't hear Barb's shouts of pleasure as she came. I lapped it all down, loving every drop of Barb's delicious juices. I sat up a moment later my face covered in pussy orgasm. I was grinning like an idiot. I saw we were now pulling into the school parking lot, I guess time flies when you're eating pussy.
"I see you need more stress relief," Mom said as she could see the huge bulge in the front of my pants, but as she went on she was disappointed, "unfortunately we don't have time to give it to you." I noticed she said "we" so I wondered if that meant there would be more group sessions like there was yesterday when I went down on Barb as she went down on Mom. "I have to get to work and you both should get to class."
We got out of the car. Barb was looking particularly satisfied as we walked side by side into the front door of the school, leading into the cafeteria first then you could find your lockers in one of the nearby hallways.
Because Barb and I were in the same class and had the same last name we had lockers right next to each other. Of course, before yesterday I really hated that fact because she and her stupid bitch friends would come by and heckle me on a nearly daily basis.
Today seemed to be no different at first. Barb's friend Linda walked up and smiled at me like the cat who just found her mouse-dinner, she was a cheerleader like Barb and was super hot like all the cheerleaders at that school. Like Barb, Linda was also wearing her uniform since they had practice later that afternoon. It showed off her big boobs and great ass. I wondered if she wasn't wearing panties either, like Barbie, which also made me wonder how they covered it up for the games if they didn't wear panties, but then realized that I was just having more perverted thoughts again.
I could tell she was already thinking of some way to be mean to me as she walked up. She glanced down and I just then realized I was doing nothing to hide my raging erection in my pants, no wonder people were giving me funny looks on the way in.
"Jesus, Danny," Linda said with a laugh as I covered my crotch with a textbook, "I didn't think you were one to stuff your pants. What is that, an actual salami?"
I blushed profusely as a group of nearby girls laughed. I turned back to my locker and tried to ignore everyone.
"Hey, don't be mean to Dan!" Barb said, surprising everyone, especially me. Even though we started having sexual fun, I hadn't expected Barbie to change her tune about me around her friends.
"What? Since when?" Linda retorted shaking her head and causing her curly red hair to flow around her face in a way that I thought was very beautiful out of the corner of my eye.
"Since now, Linda." Barb said softer, realizing that prying eyes were listening in, "My brother has to work and do school and almost never has time to unwind. He's incredibly stressed out basically all the time."
"That's not what you were saying when you were at my house yesterday." Linda pointed out, not even caring that I was in listening distance. I glanced around and noticed that outside of Linda everyone else had left to get to class. I realized I should go too or I would be late, but I wanted to hear the end of what Linda was saying, "You were saying how stuck up and spoiled he was and how he was just doing it all because he has some sick crush on your mom."
"Well, that's true, he does have a crush on Mom," Barb said, making me blush again but at least my back was turned, "but never mind that. He's a very stressed out man and he needs relief. Mom taught me yesterday that I should help out when I can."
"What? With giving your brother stress relief?" Linda asked, confused, "Are you, like, giving him massages or something?"
"Um, yeah," Barb said, she glanced at me then back at Linda, "and I think he needs a massage now. See what you did, Linda!" Barb barked at her friend, her big breasts heaving in anger causing my cock to jump in my pants behind the book I was holding in front of it. My large cock pushed against my book so hard it dropped out of hands and I blushed again, too worried that my cock would jump out of my pants when I bent over to pick it up that I just stood there with a very obvious erection in view.
"W-what?" Linda stammered, she saw my erection again, though I felt she probably thought I was just "stuffing it with a salami" like she said earlier, then she glanced at Barb as she took my hand and started leading me over to the restrooms. After a moment of confusion, Linda followed us and caught up, "You're going to massage your brother in the bathroom?"
"Well, there's not really a good place to do it otherwise," Barb explained as she dragged me into the women's restroom. I cringed, sure I was about to get caught, but there was no one else inside but the three of us, "I suppose we could use the spare cheerleading equipment room but that's on the other side of the building and we don't want to be too late for class." As soon as the bathroom door was shut, Barb turned to me, got on her knees, and yanked my pants down all in one motion. Surprising the hell out of me, and especially surprising Linda as she watched her best friend's brother's huge cock spring out of his pants.
"What the fucking fuck!?" Linda shouted, "What the hell are you doing with your brother!?" The redheaded cheerleader was even more shocked by this than Barb had been walking in on our mother giving me a blowjob in the middle of the kitchen.
