Carl turned the key in the lock of the Palmer High School 's gymnasium. Finally, after a thirteen-hour day, he was headed home. The last of the students had called home for rides and left, so he could call it a day.

Carl arrived at the school that morning before 5 a.m. As the head coach for the school's track team, it fell on his lap to be the first in on a track meet day. He supervised the loading of two busses with seventy-two student athletes, coached both boys and girls track events, settled disputes and bandaged wounds. He was glad to finally be going home.

Carl usually rode his bicycle to the school, but the night before, he had wiped out on Collin's Hill, and he needed to make repairs before it could be ridden again. So, that morning Carl jogged the three miles along the road to the school.

Carl headed for the road, but then stopped; his energy was gone. His gaze turned to the woods behind the school. If he were to walk through the trees, he would cut off nearly a mile. Carl had walked through the woods only once since he began teaching at PHS. The undergrowth made walking a challenge. But the protective shade offered respite from the merciless late-afternoon sun. Most of all, his legs cried for the reduced distance.

Carl entered the woods in a break between two juniper trees, and followed what seemed to be a path leading toward Ventura Heights , the subdivision where he lived. He had gone about a quarter of a mile when he heard laughter. It wasn't loud. Had he not stopped to tie his shoe, he never would have heard it. Then there came a moan, and then words, spoken too softly to be understood.

Carl's curiosity was piqued. He decided to investigate without revealing his presence. His ear led him to a small clearing. He began to make out the words being spoken.

"Oh, yeah, baby. Suck it deep. That feels sooo good." The voice was male.

"Oh. That's the spot. Ooooh. Don't ever stop," a girl said.

Carl dropped to his knees and crawled under the bushes to get a look at what was going on. What he saw sent his mind reeling. Carl easily recognized Sean Phillips by the tight curls of his white-blond hair, lying on his back on an out-stretched towel. And kneeling astride of Sean was none other than his twin sister, Sarah . Her head bobbed up and down as she feverishly sucked Sean's cock. Her own cunt glistened in the filtered sunlight as Sean licked and nibbled at her blood-engorged clit.

Sarah let Sean's cock slip from her mouth. Carl marvelled at its size, easily eight inches, in light of the fact that Sean was only fifteen-years-old.

"Here it comes, bro," Sarah gasped.

At that moment, Sarah's cunt exploded in a torrent of piss, flooding Sean's face and hair. Sean's tongue continued its assault of Sarah's clit as the piss flowed. Sarah threw her head back and screamed, "I'm coming." Sean's phallus pulsed as it jutted skyward.

Carl's own cock, erect since his first glimpse of the twins, threatened to erupt as he unconsciously ground his hips into the ground. He was about to let the release happen when Sarah jerked forward and impaled herself on Sean's cock. Carl marveled at how the delicate lips of her cunt easily received the engorged cock as she settled down on her brother.

Sarah began to rhythmically raise and lower herself on Sean's cock, each time pressing down until their pubes meshed, and then rising until the mushroom-head almost slipped free. Sean's hands gripped his sister's hips and spread the white globes as she fucked up and down, opening to Carl's view the tiny brown rosebud of Sarah's arsehole.

After several minutes of deep-fucking, Sean stopped his sister's cuntal assault with his hands, holding her at the apex of her up-stroke.

"Do it now, please, Sis," he croaked.

Carl stared in fascination as Sarah's little arsehole began to expand. Very slowly, a turd began to emerge. When it reached Sean's pubic hair, Sarah dropped down on her brother, squishing the shit between them. Then she rose and began shitting again. She repeated the process four times, coating her arse and her brother's abdomen.

Sarah raised herself one more time, this time allowing Sean's cock to slip free of her. She then sat his cock down into the shitty mass on his stomach, and began to slide back and forth along his erection. Within seconds, Sean's cock erupted with thick, white boy-cream.

"I'm cumming again," Sarah screamed.

Carl could not believe what he had witnessed. Never in his thirty-two years had he seen or done anything so erotic. He was about to allow himself the release he'd been holding back when Sarah shifted back and plopped her shit-smeared arse down on her brother's face. Sean responded by licking her now shit-covered pussy. As if that were not enough, Sarah took Sean's shitty cock and began to lick her shit from its still erect surface. Carl's cock began to pulse as he pumped the largest load of his life into the confines of his jock strap.

Carl lay in silence as Sean and Sarah cleaned themselves on the towel, put on their track uniforms and left. Then, he crawled into the clearing and picked up the piss-soaked, shit-covered towel. Though it had been only minutes since he came, his stocky cock again rose to erection. He released it from the confines of his cum-soaked jock strap and began to stroke it. He brought the towel to his face and deeply inhaled the scent as his hand flew up and down on his hooded maleness. In moments, his cock erupted again.

The weekend dragged on forever. The memory of what he had encountered interrupted his sleep and plagued his waking hours. By Monday morning he had jacked off at least fifteen times.

Carl's return to school on Monday morning brought a new challenge. Only two hundred students attend Palmer High, so Carl encountered both Sean and Sarah several times during the day. Each time, his cock responded by immediately stiffening.

By the seventh hour, when both Sean and Sarah had P.E., Carl knew he had to act.

"Sean," he called as the youngster ran by. "I need to see you in my office after school, and bring your sister with you."

Though in actuality only ten minutes passed, it seemed like hours to Carl before the final bell for the day rang. Then, another half-hour drug by before the locker room cleared. Finally, a knock sounded at his door.

"Come in and have a seat," Carl said as he checked the training room to insure its desertion. His hand tripped the lock as he closed the door to his office. He walked to a locker on the wall opposite where the twins sat, still in the dark as to the reason for their summons. "I believe this is yours."

Carl turned from the locker and threw the once-white towel to the children. Only the yellow stains and the acrid odor remained of the piss, but there was still plenty of shit, now dried in the terry cloth.

Both twins gasped in unison.

"Don't worry, kids. I have no intention of telling anyone of how you two spend your free time," Carl assured them. "I just want to join you."

Carl had removed his jock strap while he waited for the twins to arrive, and his throbbing cock met little restraint from his gym shorts. Both Sean and Sarah stared at the tent it created.

"Man, you're freaking me out," gasped Sean. "I gotta piss."

When he stood to leave the room, Carl stood in his path. He reached out and tugged Sean's already low-hanging pants down. Then he dropped to his knees and pulled the white Jockeys down.

"You can go right here," Carl said. Then he flicked his tongue on the head of the boy's flaccid sex. When he met with no resistance, he pulled the cock into his mouth. The warmth of the oral cavern caused Sean to lose control. His piss began to trickle, and then built to a gusher, filling his coach's mouth.

"Oh, hurry. I have to go, too," Sarah pleaded. She frantically pulled her clothes off as she waited for her brother to finish his piss. Once naked, she sat down on the chair and spread her legs. Her young cunt glistened, as Sarah released a few drops of her piss and then spread them over the puffy lips with her finger.

Sean's flow finally stopped. Carl slid over to Sarah and placed her legs over his shoulders. He buried his face into her crotch, engulfing the entire pussy with his open mouth. Sarah's release was immediate. Piss poured from her hole and down her coach's open throat. As the flow began to subside, Sarah farted. The smell immediately filled the room.

"I hope you're hungry, cause I haven't shat in two days," Sarah growled.

Carl moved his mouth down to the brown arsehole. His tongue invaded the tight sphincter, but almost immediately met resistance on the inside. Sarah grunted, and Carl's tongue was forced out of the teenager's arse by a huge log of dark brown shit. As a second turd began to snake its way from Sarah's arse, Sean swung his leg over his sister's torso, placing his arse directly over Sarah's pussy. "Double your pleasure, coach," Sean laughed as his arse opened. As Sarah's arse-fudge filled the coach's mouth, Sean's shit spread over his face. What Carl could not swallow, he caught in his hands.

When both had finished emptying their bowels, Sean said, "I gotta fuck. Sis, lean over the desk and I'll give it to you from behind."

Sarah positioned herself with her elbows on the desk and her arse jutting back. Sean stepped behind her and slipped his now-hard meat into her filthy shithole. Just as he got a rhythm going, Sean felt a pressure at his own arsehole. Before he could actually figure out what was happening, Carl slid his thick cock into the boy's virgin hole. Sean experienced a moment of pain, but the pleasure that was building in his cock forced it from his consciousness. The three established a rhythm, with Sean sliding into Sarah as Carl slid out of him.

"Fuck me hard," Sarah screamed. "I'm coming."

"Oh, oh, OH! Me. too," cried Sean.

The contractions of Sean's sphincter as he pumped his sperm deep into his sister proved more than Carl could stand. His cock erupted, filling Sean's virgin arse with his man-cream.

Once the throes of orgasm subsided, the three climbed into Carl's single stall shower to erase the signs of their perversity. As the water cascaded over them, Sean said, You know, I think I'm going to enjoy my last two years here at Palmer."

"Me, too, bro. Me, too," said Sarah.

Carl could only smile, though his cock again began to swell.
