Chapter 1
It was late she had just finished her work for the year, but there was one the last thing Principle Celestia of Canterlot High School needed to do before she could go home and enjoy her winter vacation. Check every door to make sure it was locked. A tedious job, but one she had to do.
Starting on the third floor Celestia went door to door; checking to make sure the teachers had locked them like they were supposed to, her mind blank as she did so. She grumbled with frustration with every door she checked. Luna was probably at home snuggling up in a blanket. She wished she was at home too, but with someone other than Luna to snuggle with.
Her sex life has not been great since breaking up with her boyfriend two years ago.
Finishing the second floor Celestia preceded to the first, checking the offices and the remaining classrooms. A feeling of glorification filled her as her work drew to a close. All she needed to check was the locker room and she would be done!
Starting with the girl’s she found nobody hiding inside. Why someone would be here at seven at night was beyond her, but the superintendent was very strict about keeping students out during long breaks. After what happened last year, she couldn’t blame him. Why two students decided to hideout at the school for a sexual adventure was beyond her, she never did anything like that when she was young. Luna called her a prude for it as she went on about her first encounter with a boy in high school. Luna’s rebel phase happened early, Celestia’s was in college and it didn’t last long.
“Can’t be a rebel long if you want to be a school teacher,” she chuckled to herself, though the laughter faded quickly, a part of her remorseful she didn’t take more advantage of her youth. Not that the thought about shacking up in the school really aroused her, but there was an appeal to at least try it.
Imagining all the things she could have done Celestia headed towards the boy’s locker room. Key in hand she was about to lock the door when she heard the sound of the showering going.
Was someone here, she wondered or did someone just leave the water on? With only one way to find out, Celestia opened the door quietly and walked in. On the bench was a stack of clothes, she picked them up and carried them towards the showers, fully intending on giving the person inside an earful.
Rounding the corner Celestia saw the steam of the hot water and a figure showering, “Hey!” She yelled only to slip on a bar of soap on the ground. She screamed as she slipped and slid on the wet floor and into the showers. Coming to a stop at the wall she looked up to see one of her students, Senior Big Macintosh Apple, he looked down at her with surprise and embarrassment, his dick becoming erect at the sight of her wet clothes. She eeped as she covered her chest, he could probably see her tits very nicely.
“Um… ah… here,” said Mac offering a helping hand she took.
Silently both of them got out the showers and returned the lockers. He looked around for his clothes, but they were wet along with hers, leaving him naked.
“Don’t take this the wrong way,” She said taking off her wet clothes, including her underwear. “They’ll just dry faster this way.”
“Right,” replied Mac as he hung up his own clothes to dry, his face even redder as he tried to hide his erect dick with his left hand. He wasn’t doing a very good job, the damn thing was huge!
With nothing to do but wait for their clothes to dry, Celestia and Mac sat on the bench not looking at each other… most of the time. Celestia caught Mac looking at her a few times, not she blamed him he was clearly trying not to look. She wasn’t blameless either. The size of his member was really attention getting, its length was half way to his knees!
“So,” She said sneaking a peek. “Why are you here, showering I mean?”
“Water heater at home is busted, Applejack and Applebloom went to shower at Rarity’s, I wanted to take a hot shower after chores so I drove back here knowing the doors wouldn’t be locked yet for the year.”
“I see.”
They sat in silence. Stealing glances at each other. Celestia kept an arm across her breast and a hand on her crotch. This would be so bad if anyone caught them like this, no matter the circumstances, if they had been… NO! Bad Celestia! He’s your student! She berated herself, but yet she felt moisture on her fingers. She gasped as she removed her fingers that had worked into her crotch, great, she was turned on now.
Glancing again at Mac’s still erect member Celestia felt her fingers slip into her folds again, her breath shortening as they began to work her folds faster. Suddenly a naughty, stupid idea crept into her head.
“You graduate this year, right Mac,” He nodded. “So you’re…”
“Eighteen.”
The last of her hesitation flew right out the window. Eighteen was legal, it was still bad to have relations with a student, but he was graduating, if he didn't talk everything would be fine.
Celestia moved down in front of Mac grabbing his shaft between her hands and placed it between her massive breasts, “Don’t tell anyone.” She told him moving her tits up and down around his shaft as she licked the head. Bubbles of precum spilled out and she hungrily licked it up. She picked up the pace of her tit job taking in more and more of Mac until he suddenly stood up and rammed his entire length down her throat. Her eyes widened as he grabbed her hair and pulled back and rammed his entire length down her through in and out, in and out like a jackhammer, skull fucking her like a common slut. His hot dick quivered in her mouth, he was close, his balls slapped her face as he forced his entire length into her mouth and cummed. Hot white cumming spilling out of her mouth as he pulled out.
“Sorry, I couldn’t help myself!
She calmly swallowed what she could, the rest spilling down onto her breasts. Looking at the panicked Big Mac she forced him down onto the bench, his dick still hard as a rock.
“Shut up, it’s my turn for some fun.” She said breathing heavily as she mounted him. He was so huge and she was tight from a lack of doing it for so long. Slowly she lowered herself onto the shaft. The big red member was hot and slick and spread her wide open. She felt like she was losing her virginity again as she slammed her hips down, taking Mac’s entire length. She screamed silently as his tip forced open her womb.
A pair of strong hands grabbed her hips and he started moving her before she was ready. This was supposed to be her turn! He flipped her over, forcing her ass into the air as she mounted her like a wild stallion and plunged his hot dick in and out. His balls slapped her legs as he thrust, penetrating deep every time.
“Principle… I’m…”
“Don’t pull out! I want it inside!” She screamed forcing her body back before Mac could pull out. He fell back his dick stuck all the way inside her. Hot sticky cum filled her belly, the amount making a small bulge in her stomach.
“Ooh… that’s good…”
They both laid there in the afterglow. Celestia removed herself from Mac’s shaft, cum spilling out of her crotch and onto the floor. Great, she would have to clean that up. As she kneeled down the door opened and Luna entered the lockerroom. Celestia froze as she felt her sisters gaze fall on her cum filled cunt.
“So this is why you weren’t home yet,” Luna said coyly as looked at Mac’s shaft and back to Celestia’s ass. “I hope you intend to share.”
