Billy knew his teacher was gay - well, he wished he was anyway. All the signs were there. He was not married, he was pushing forty and he was always a little too smartly dressed. Mr Sanderson was a big beary man. Full beard, nice warming smile, and bright eyes. He had a nice belly that looked like it never went hungry. Billy had always been attracted to bigger, older men - so when he got Mr Sanderson as his final year science teacher he really thought Christmas had come early.

Billy was 19, and an early developer. He was shaving every day and had more hair in more places than any of his classmates. His five o'clock shadow made itself apparent at 10 am in the morning. He was chubby but had some muscles in the right places. He had known he was gay from an early age - he was a virgin but had watched enough hard core porn that he had managed to download on the net to work out w! hat he should be up to in bed.

His first lesson with Mr Sanderson had been like a dream. He watched him from his seat and hung on his every word. He couldn't have cared less about the subject - all he wanted to do was to undo that shirt and run his hand through the thick black hair that he could just about catch a glimpse of. It had been a warm day and his teacher had rolled his sleeves back to reveal his huge thick forearms and their thick covering in fur. Billy had to be careful to hide his throbbing erection that he could feel pressing against his thigh all the way through the lesson. Mr Sanderson had 30 other students to attend to so he hardly laid eyes on Billy, but when he did Billy's heart leapt about six feet into the air, along with his cock.

That night, Billy rushed home to fantasise about Mr Sanderson. He jumped into the shower, cleaning himself as quickly as possible, leaving his cock until last. He spent almost a half hour soaping up and washi! ng off his cock and balls over and over. He would rub the soap into his head until his legs bucked and then rinse the bubbles off with the shower head, ready to rub the precum into the back of his head. He would rub his palm in a circular motion across the top of his head until he could hold it no longer and he would let fly with a stream of piss. He savoured the feeling of his pee pouring out of him while his cock was stiff as a board. He played with his dick for ages until his father banged on the door complaining about heating bills.

He ran to his room and locked his door. He could see the image he wanted to get to in his mind - Mr Sanderson, balls deep in his tight cubby ass - fucking him hard and fast - but he wanted to imagine the scenario leading up to that. Rubbing his hands all over the big man's chest and belly - teasing his erection through his trousers - pulling his swollen daddy cock out and sucking him hard, licking his tight fat balls and driving the bi! g man wild with excitement. Billy's hand gripped his cock and he tugged furiously imagining the big man fucking him harder and harder then pulling out in time to shower Billy with wave after wave of white-hot come. It wasn't long until Billy came and his orgasm was a mind blower. He emptied his tight balls all over his hairy chest and belly - covering himself with his load. Billy mopped himself up and was amazed at the strength of his orgasm. He began looking forward to his next lesson with Mr Sanderson.

* * *

However, the next lesson didn't go too well for Billy. Mr Sanderson was in a particularly nasty mood and decided that Billy was a worthwhile target. Everything that Billy said or did was pounced upon and he began to imagine killing his teacher instead of blowing him! Eventually, Billy cracked first and a quick rude comment landed him in detention after school the next day. He couldn't believe it! A Friday night and he would be in detent! ion!

He managed the remainder of his lessons without incident and turned up at Mr Sanderson's office after his last class on the Friday afternoon. He knocked on the door and heard his teacher's voice ordering him to come in.

"Close the door, boy." Said Mr Sanderson, sat at his desk. Hands behind his head, leaning back in his chair. Billy took a quick glance at the bulge between his teacher's legs.

"Yes, sir." Said Billy, closing the door.

"Do you know why you're here?"

"Yes," said Billy, a little too sarcastically.

"Yes what?"

"Yes, sir."

"That's better." Said Mr Sanderson, standing up and walking towards his student. "You know what happens to boys who give me cheek?"

"No, sir." Replied Billy, struggling to hold his tongue.

"They get disciplined." Said Mr Sanderson, as he walked passed Billy towards the office door. He clicked the lock on the inside and turn! ed back to his student.

"What you gonna do? Hit me?" said Billy. "This isn't the 1850s you know."

"Slow learner aren't you?" said the big man, as he clamped his two large hands on to Billy's shoulders and forced him to his knees.

The penny dropped and as Billy looked up towards his teacher's face - he saw a glint in his eyes. Billy looked back to his teacher's crotch and saw the outline he had been spending every lesson staring at.

Billy extended his tongue and traced along the bulge in the big man's trousers. He tried to suck the head through the fabric, while at the same time searching for the zip. He undid the button and zip and freed the thick juicy surprise inside. Mr Sanderson's cock flopped out of the hole in the front of his boxers and pointed straight at Billy's face. Mr Sanderson wasn't immensley long, but he made up for it in width. His cock was very fat and uncut - the skin covering the swollen head except for a tiny par! t at the end where his hole was. After taking in the glory of this amazing cock before him for a few seconds, Billy's tongue dived into the hole the skin made and he began sucking on this fat sausage as fast as he could force it into his mouth.

Using a free hand, Billy forced the skin back and forth over the head as he sucked. He used his other hand to coax out the two massive balls that accompanied this monster and slowly carressed them as he worked on milking the big man's dick. He was obviously pleasing his teacher as he was purring quietly above him. He looked upwards again at his teacher with his cock deep into his mouth. He had removed his shirt and Billy looked up over his furry belly and dense covered chest to see his teacher with his eyes shut and a pleasured expression on his face. He was slowly fiddling with his nipples that Billy could see were both pierced.

Mr Sanderson placed his fat hands gently on either side of Billy's face and slowly began! to fuck his face. Billy savoured every moment as this fat meat slipped slowly in and out of his mouth, he was dribbling like mad but he didn't care. Mr Sanderson worked his fat cock deeper into his student's mouth with every thrust until Billy's chin and nose nestled amongst his thick mound of black pubes. Sensing that he was about to choke, he pulled out and let him rest - his cock laying atop his head. Billy didn't take too long recovering and began to suck greedily on the huge pair of balls that hung tightly below his teacher's cock. While he sucked, Mr Sanderson slowly played with his foreskin with one hand, the other fiddling with his nipple.

"Oh god, boy." Said Mr Sanderson. "You're such a naughty little cub. Such a bad boy." All Billy could manage in return was a few moans as his mouth was full with a fat, juicy ball. He stopped after a while and looked back at the now wet and juicy cock before him. There was a large droplet of precum emerging from the hole in t! he end which he lapped up as quickly as possible. He felt his teachers hands on him again, but this time they were lifting him up off the floor. He was pulled forcefully into a deep embrace by Mr Sanderson who kissed him deeply, his warm and wet tongue diving into his mouth. Billy let the big man hold him with his massive hairy arms, he loved the sensation of being pressed against the big furry body infront of him. He felt strange being pressed against this big beary man while still wearing his school uniform - as if reading his thoughts, the big man began to strip him off.

Billy was bent over the desk in the office and nervously waited for what the big man had in store for him. He felt the big man's hands caress his back and his buttocks. He wasn't prepared at all when the big bear pulled his cheeks apart and dived in with his tongue. Billy had to stop himself from crying out with the shock as his teacher rimmed him with his white hot tongue. His tongue explored deep! into Billy's hole and he just couldn't get enough of that overwhelming sensation. He tongue fucked him gently for a long time, Billy could do little but moan quietly.

"You like that, boy?" Demanded Mr Sanderson, as he stood up and inserted a f1nger slowly into Billy's hole. He wriggled it about, until he found his prostate.

"Oh fuck yes!" cried Billy.

"Excuse me?" said Mr Sanderson angrily, prodding him stiffly.

"Oh yes I love it, sir." Remembered Billy.

"That's better. Now, do you want the real thing?"

"Yes please, sir."

"Ok, I think you deserve it now."

Mr Sanderson removed something from a side pocket in his sports bag and Billy suddenly felt something cold and wet being spread over his hole. He braced himself for Mr Sanderson's fat cock.

He felt Mr Sanderson standing up against his rear and then slowly felt something hot and wet being pressed against his cheeks. It ! wormed its way slowly between them, searching for his hole and eventually found its target. Mr Sanderson gently pushed with his hips and his head started to penetrate Billy's hole. He slowly pushed back and forth, letting Billy get used to the width until his head was fully inside and passed his sphincter.

"You like that, boy?" asked Mr Sanderson as he slowly started fucking his boy in small gentle strokes.

"Yes sir," cried a muffled voice as Billy had forced his face into his clothing on the desk.

"Oh, you're such a tight little bottom. So tight, so naughty." Mr Sanderson began to plunge slightly deeper into Billy's ass with each thrust of his hips. It took a long time but eventually Mr Sanderson was forcing his whole cock into his boy and his fat balls were squashed up against Billy's ass with each thrust.

Billy was in heaven. He had never imagined that being fucked like this could feel so good. With each thrust, this big man was! making his cock throb and he was loving every second of it.

"You think you can take it a little harder?" asked Mr Sanderson.

"Yes, sir!" cried Billy.

"Good boy," said Mr Sanderson, who began to quicken his pace. He began to get harder with his thrusting and Billy could feel his ass weakening with every lunge. This big man was banging away at his rear end and the pleasure was overwhelming.

To get a better purchase on his boy, the big man raised a foot and placed it onto the table top. He fucked this tight young virgin ass for all he was worth. His balls slapped against Billy's ass and with each thrust it felt like he was getting deeper into him.

Eventually, Mr Sanderson came to his limit and withdrew. He quickly flipped Billy onto his back and held his hand tightly over the end of his cock. He gave it a few rubs with his hand and with a large bellow his fat cock exploded and covered Billy in spurt after spurt of white h! ot come. Mr Sanderson's orgasm seemed to last for ages and Billy rubbed as much of his reward over his belly and nipples as he could.

As Mr Sanderson slowly caught his breath, Billy started to rub his teacher's come into his cock, the hot wet juice lubricating his hand as he rubbed it over his head. He shuddered with pleasure each time his hand moved up and over the ridge of his glans. He was getting faster and faster, closer to the point of coming when he felt his teacher's finger worming its way into his ass. His teacher searched for his sweet spot with his podgy finger, probing him left and right. Billy couldn't tease himself much longer and grabbed his cock with his fist and yanked harder than ever. It didn't take long before Billy was once again covered in hot white come, his own this time.

Billy looked deep into the dark brown eyes of his teacher as they both struggled to catch their breath. However, this didn't last long as there was a knock at the door.

Startled, they both looked terrified into each other's eyes. They knew they had done something bad but had hoped they wouldn't be found out.

"Um, who is it?" asked Mr Sanderson, quickly pulling his clothes on as fast as he could. Billy made an effort to do the same, but he was too exhausted to even get off the table top.

"Roger, it's me, Dave." said the voice. Then a pause. "Everything alright in there?"

"Yeah," said Mr Sanderson, though the panic in his voice was obvious. "Just give me a minute."

"What's going on in there?" asked the voice, which was getting sterner.

"Nothing, Dave - I'm just getting changed after having a run." And at that, Mr Sanderson ran to the door and opened it slightly, speaking to the voice through a small gap. Billy struggled to get his clothes on as fast as he could, but he was wet with come and the stains were obvious to see on his shirt.

Dave was obviou! sly not convinced as he pushed past Mr Sanderson and into the office, just in time to see Billy zipping up his fly. His eyes darted between Mr Sanderson, Billy, the wet patch on the front of Billy's shirt and then back to Mr Sanderson's obvious state of overheated exhaustion and panic and then the penny dropped.

"Oh," said Dave. "I see."

"It's not what it looks like, Dave." said Mr Sanderson, but the tone in his voice spoke otherwise.

"Roger, don't bother. Billy, I think you'd better get off home. Your mother will be wondering where you are."

Billy pushed past his teachers without a word and rushed away from school as fast as he could. He was terrified. Everyone was going to know. He was done for.

His teacher was in serious trouble.
