Permissive Fantasy II

 This is another one of those pure-fantasy things without sex laws. If you don't know what to expect, check out the warning on the first one.

-----------------------------

Every week, the school's PE classes have 4 sessions a week, with the 5th being Health class. That included information on drugs, preparing for later life and what most guys looked forward to, Sex Ed. The senior students had the class, too, after learning the basics in lower school, to be taught the more detailed aspects. Mr Crewe taught my Health class, and on the day of Sex Ed, ushered us into the classroom in nothing but his underwear. I had chosen to wear the same, but most of the other guys didn't bother at all. Their excitement about the coming lesson showed.

"Alright, boys," Mr Crewe announced to settle the boys. He was a little on the overweight side, with a bit of a gut but by no means unnattractive (he was surprisingly hot), with short brown hair and a bit of stubble left on his chin. His navy underwear bulged with his cock and balls, making me want to reach out and grab them. I resisted, in case he paused the lesson. The others wouldn't like that.

Mr Crewe went into a short discussion about sex ed, about what we learnt in lower school et cetera, when a woman walked into the classroom. She was blonde, thin, and had some decent-sized breasts. She wasn't wearing anything at all.

"Ah, here she is," Mr Crewe said. I jolted myself. I hadn't been listening to his speech, he must've mentioned who she was.

"Boys, this is my wife, Claire." Claire waved slightly at the group, who were watching intently. Some of the boys nearby started to get harder. "She'll be helping out in the practical session later." I grinned. The class went on for a bit, with Mr Crewe going on about foreplay, the best ways to go about it, and some of the best ways to actually engage with a woman. He also gave a few examples of what to do with another guy.

He brought up Andy, a guy who sat behind me, to the front and sat him on the desk. He and his wife both showed the class the best way a handjob is given, and he used Andy and his wife to demonstrate fingering. He called up a few others to demonstrate on Andy and Claire, too, until Andy came onto the floor and Claire said she wanted for us to stop. Those who had been called up (including Andy) were given A's for the class.

We moved on from foreplay and got into what Mr Crewe called "the good stuff". He went into a little detail, but it was basically what any of us would learn by watching a good porno. Then, he came to the practical.

"Max, get up here," Mr Crewe said. I practically leapt out of my seat. Mr Crewe held and positioned me in front of his wife, who had turned on the desk and was laying with her legs spread, facing me.

"You can forget about foreplay, Max. Make her climax and you'll pass." I pulled down my underwear and pulled Claire closer. Her tits were leaning on either side of her body and she was holding onto the sides of the desk, looking up at me with a look of both greed and expectancy. I held her thighs, guided my cock into her pussy and pushed. She closed her eyes and let out a soft moan. I pushed deeper and she moaned louder, but not much louder. I could hear some of the other students mumbling to each other.

I sped up, thrusting in and out of her, making her moan louder and faster. It really turned me off when girls screamed or moaned with really high-pitch, but Claire didn't reach that level. It was good, really. I leaned over her and held onto her hips as I pumped faster, making her groan as well. For several minutes I pumped, occasionally leaning forward further to suck on her beautiful tits (which made her moan higher, so I didn't do that very often).

"Okay," Mr Crewe said behind me. "While Max is demonstrating the hetero- form, I'll show you all the homo- form, too." I turned and saw Mr Crewe bending over, removing his navy underwear. I grinned. Mr Crewe's cock wasn't huge, but it was a decent size. He stepped closer to me and touched my sides. I noticed I was slowing down with Claire, so I pumped faster. One of Mr Crewe's hands left my waist and I was sure he was guiding his cock. I leant forward to let him spread my cheeks to get his cock inside me.

He pressed and his cock slid through my hole. I moaned and stopped moving. It was a little hard, moving while his cock was inside me and I was inside his wife. He pushed deeper and I felt incredibly turned on. I thrusted into Claire, moving my ass off his dick. I continued thrusting, each time I pounded his wife he pounded me. Mr Crewe muttered encouragement into my ear, gripping my waist tight and beginning to thrust himself. I stopped thrusting and let his momentum move me deeper into Claire.

Claire moaned louder and higher, turning me off her a little, but I realized she was coming. Fast, I thought. I guess she was easily pleased.

"Good work, Max," Mr Crewe said. He pulled out of me and helped his wife off the desk. They kissed goodbye and he told her it was okay for her to leave. She smiled at me as she left the classroom, followed by so many students' eyes.

"Now, we'll end the topic of herero- today, but we'll go on with homo- for a bit longer. I'd just like to finish with Max first..." Mr Crewe turned back to me and bent me over the table. I felt him re-insert his cock and thust faster than before. I felt his belly hit the top of my ass every time he thrusted, and his hands gripping my waist just as hard as before. I relished the feeling of his cock plunging into me, faster and harder each time, being fucked by my teacher...

I felt him tense up and shoot his load, letting himself shoot up into my ass. His jizz ran out of my ass when he pulled out, lubricating my hole.

"Okay. Dennis, come up," Mr Crewe said, sitting on his desk. Dennis, a burly but short guy came up, naked like most other students. "Come inside Max and you'll get the same grade as the others."

This went on for several other students. I was rammed by Kyle the twink, Bradley the tall and hairy, and Rex the muscled stud. By the time they'd finished, class was nearly over.

"Well done, boys," Mr Crewe said. He had put his underwear back on and given me a towel to dry my lower body off. He guided the boys out of the class, each one of them being somehow satisfied (a few had jacked off to one display or another). I was about to leave when Claire, who was now wearing a bra, tried to enter first. I awkwardly sidled past her when she stopped me.

"Did you end up getting off, Max?" she asked me.

"Not really, bu-"

"Matthew," she called to Mr Crewe, who looked up from his desk. "Did you get everone BUT Max off?" Mr Crewe looked puzzled.

"Did I? Sorry, Max, come over here." I eagerly walked back to his desk. His wife followed me, sitting up on the desk in front of me. It didn't take a genius to work out what she was offering. I pulled her panties off and pulled her closer, taking my cock out of my underwear again and pushing it in. Faster, I pumped, watching her moan and smile, obviously loving it. She grabbed her husband's crotch and massaged it, prompting him to drop his paperwork and stand up.

Mr Crewe removed his underwear as I helped Claire over onto her front. He grabbed her husband's cock and pushed it deep into her mouth, sucking and pushing her head on and off. I pumped into her faster, leaning forward over her again. Mr Crewe looked over at me, biting his lower lip, watching my cock slam into his wife over and over. I grinned and pumped into her even faster, her moans muffled by her husband's cock.

When I finally came all over her ass, Mr Crewe wasn't far behind. I didn't stick around to dwell on whatever they wanted to do after sex, just mopping up with the towel and putting my underwear back on.

"Thanks, Mr Crewe," I call back as I leave his classroom.

"Think nothing of it, Max," he answered. I closed the door on them and headed out to lunch.
