Chapter 1

Monday Morning

The school had called our parents yesterday afternoon and informed them that Sarah and I would begin our participation in the naked in school program what is now this morning. Sarah was at my house for the day and night. We only lived four houses away and she slept over often.

I am Mark Andrews. I am six feet, three inches tall, and play football as a wide receiver and baseball as a third baseman. My mother answered the call since my little brother, David, had just finished shooting a load into her butt and his twin sister was sucking her clean. Dad was on the bottom of a Sarah sandwich with his cock buried in her cunt. I was on top pounding into her ass. Caitlin was now licking Mom's butt when the call came. She stood and walked into the kitchen. David stuck his cock back in Caitlin's mouth and she happily sucked him.

Sarah had been orgasming non-stop since she was double penetrated and I was spanking her ass cheeks with every thrust. Dad was pulling on her nipples twisting them as he pulled. She loved every thrust into her body and the sexy punishment she was receiving. Dad and I reached our orgasms together and slammed deeply into Sarah's holes making her scream with passion as she reached a huge orgasm of her own squirting onto Dad.

Mom came in as we rolled apart and said, "You two will be naked at school Monday morning."

I said, "Cool."

Sarah said, "Oh, yeah. I am permitted completely."

I smiled. "Yeah, I am too. It should be fun."

Sarah's phone rang and Caitlin handed it to her as she lay. She lay in front of her and began to suck our loads out of Sarah's holes. David moved behind Caitlin and shoved his cock all the way in her ass. I had ass fucked my younger sister twice already today and my seven inches had opened her nicely for David's six plus a hair. Sarah got off the phone and moaned to Caitlin's mouth working her holes.

She said, "That was my mom telling me she received the same call. She asked me if I wanted to come home tonight but I said, 'No.' Since I'll be naked tomorrow, I can't be dripping someone's load on the floor. In the morning, I'll douche and take an enema. This will be fun. Mark, we've never fucked in class much less anything else." Caitlin's nose pushed into her cunt when David pounded Caitlin hard and Sarah had a small orgasm.

Like most nights, she slept in my arms. Tonight, my cock was embedded in her ass. We got up in the morning and she gave me an energetic blowjob. We went into the shower and bathed and played. She douched with some help from me and then I gave her a piss enema while we were still in the shower. Sarah loved that almost as much as being fucked in the ass. We gave her two more warm water ones to truly clean her out. We toweled dry and left the bathroom for my bedroom. Sarah pulled on a mini skirt and a simple pullover blouse with ankle socks and sneakers. I grinned. I pulled on jeans with a tee shirt, ankle socks, and sneakers of my own. We were ready to go. We were in advanced placement classes but handled our homework together easily.

We went into Principal Norris' office with another couple. We shook hands and I pulled off my shoes so getting naked wouldn't be an effort. We striped and I was lacing my sneakers when Principal Norris came in with the school Advisor, Miss Patterson.

Principal Norris was a fine looking woman in her middle forties, petite with a slim figure. Miss Patterson was almost six feet tall and built beautifully though large size. Her breasts and hips were large and looked even bigger with her tiny waist. She was a frequent attendee at our parents' parties and had pulled many a train. She wasn't married and changed men often. After a month, they always looked haggard but happy.

The other two seniors, Warren Jones and Amy Redd, knew each other but didn't go out together. They were average students doing well in average courses. Neither had a remarkable body.

Miz Norris noticed that Amy's pubic hair was trimmed. She was surprised to see that I was clean-shaven of all public hair. Sarah was shaven except for a small triangle pointing down at her clit. She said, "I see you're all readied. Warren and Amy, your slips show no penetration and that you won't participate in 'red' activities. Mark and Sarah, your slips don't show any limitations for either of you." She was a little surprised at that since it was probably the first time for no limits participants who were paired. "If none of you have any questions, you may leave for your homerooms. Have fun this week."

Sarah and I went to our homeroom together since we were in all classes together. Our parents had been friends for years and we got to know each other when very young. As soon as we were old enough, our families exposed the sexual activities within our families and we went after each other. Sarah's breasts were a great, firm B-cup with long sensitive nipples. As we walked along the halls to our homeroom, guys and a few girls were flipping her nipples. Girls were fondling my hard cock until I was leaking precum. Sarah's legs glistened with her cunt juices.

We entered the homeroom and Mister Calloway said, "You two look like you both need relief. Would you like to help each other out?" We nodded. I pushed Sarah face down on his desk and buried my cock in her cunt pounding her hard until we orgasmed. He handed both of us tissues. Sarah wiped her cunt but, before I could clean my cock, she sucked me to the root swallowing and sucking until it emerged from her mouth clean and fairly dry. The other students were making sounds like "Wow!" and "Oh!"

We took our seats but everyone's eyes were on us. Everyone who knew us knew that we were an item but that we weren't exclusive. Sarah had helped the cheerleaders take on the football team two different times. Once, she lay on top of me with my cock buried in her ass while many of the rest of the team ran a train on her cunt filling her with semen until Mindy and Tracey took turns sucking her. She sucked them, too.

Mister Calloway said, "I understand that both of you are in the program with no limitations." We nodded. "Okay. Good luck." He went on with the usual announcements. When the bell rang, we headed for our first period class.

We walked the halls to our English class. On the way, one of the guys in the homeroom walked beside Sarah opposite me and put his hand on her ass fondling it all the way. We entered the English class with the other advanced placement seniors. Miz Hudson taught that class. I thought she was married but I'm not sure. She was almost as tall as Sarah and slim. Though she was over forty, she was an attractive woman though without much in the way of breasts.

As we walked in, she said, "I see you are two of this week's participants. What are your limits?" One of the rules is to cooperate and we both had to admit that we had no limitations. She said, "No limitations? This will be an interesting week. I see you're hard, Mark. Sarah, I see you're wet. I'll have to get you relief.

"First, I have something for you two. We will keep them in my desk and you will wear them when in this classroom. She had four wooden clothespins. Each of us got one on each of our nipples. She had one of the guys lick Sarah's nipples until they extended and then she clipped them. She licked my nipples until they elongated a little. I was moaning when my nipples were clipped. Those clothespins hurt! They also made my cock harder and Sarah wetter.

Miz Hudson said, "Would you like relief?" We nodded moaning. She asked for volunteers. One of Sarah's friends, Mindy, came forward and began to suck my cock taking it deep into her throat allowing me to thrust into her face. Another friend, Tracey, went to Sarah and began to suck her cunt pulling some of my semen as well as taking Sarah along for an orgasmic ride. We both had good cums. I unleashed a good second load into Mindy's mouth and she swallowed every drop. Sarah came to Tracey's mouth and fingers including one up her ass. Miz Hudson noted that. Just after we came, she began the class.

At the end of our class, Miz Hudson collected the four clothespins from our nipples. We again went through the halls being fondled. We were both horny by the time we reached the classroom. Mister Astor smiled as he saw us enter. "Do you need relief?" We nodded. "Go ahead up here at my desk."

Sarah bent over the edge of the desk. She hissed at me, "Mark, please do my ass. I am so hot there!" I walked behind her and pushed deep into her ass with one thrust. She moaned, "Oh, yes! Fuck my ass!" Mister Astor and a good portion of the class looked shocked. I began to pound her ass hard. Mister Astor looked to confirm that my cock was actually in Sarah's ass.

I came hard in her ass and pulled out slowly. Sarah grabbed my arm to bring me around to her face and took my cock in her mouth sucking me. She wiggled her butt. I said, "She wants another cock in her ass. Will one of you help her out?" Michael Hall, one of the guys who played two sports like me stood and walked behind her. He unzipped and let his jeans drop with his cock sticking out of his boxers. He pushed into Sarah's ass and began to fuck her hard. You could hear the sound of his pelvis slapping against her butt cheeks. By the time he unloaded his jizz into her, I was clean and ready to sit down. I whispered to Mister Astor, "Do you have a glass?" He looked curious but retrieved one from his desk. I handed it to Sarah whispering, "Fill it and drink the loads." She grinned. Putting the glass on the floor, she squatted above it and pushed the cum from her rectum into the glass. When nothing more came out, she wiped her ass with some tissues that Mister Astir gave her.

Then, with her knees straight facing away from the class, she bent over and took the glass in her hand, turned and lifted it to her lips, and swallowed it all down. That blew minds. Everyone sat in complete silence.

He went through the class and discussed fashions at different periods in history and how government reacted to those fashions as well as to nudity. It was interesting.

When the bell rang, we took our books and left for our next class next door. It was an advanced sociology class. It was taught by Missus Clarkson. She and her husband were free spirits and had come to parties at both my house and Sarah's. I had fucked her many times. At one party, she and Sarah had gone into a sixty-nine and I took Sarah's ass while she was on top. When we had all cum and rolled apart, Dad rolled her on her stomach facing Sarah's leaking ass and pushed his cock deep into her butt. The force of his thrusts pushed her forward and she began to suck Sarah's ass. There was more history with her and her husband who had a long, thin cock that my younger sister loved up her ass. Caitlin had to have him that way as soon as she saw him.
