Kayla!

Of course, the popular girl was the first one to get up from her chair and walk over to the front of the class. She claimed the center of attention as she stopped in front of the blackboard, looking over at the rest of the students looking at her curiously. "So, what subject do we want?" She asked with a soft grin.

"Sex ed!" One of the guys immediately blurted out, as laughter filled the class at the idea.

"Sex ed, huh? I'll need a volunteer then..." Kayla smiled innocently as she looked around the class, stopping at one of her best friends. "Alva, get your ass over here! You'll be my beautiful assistant for the course," She commanded, and Alva didn't hesitate to rush over towards her friend. The rest of the class cheered, although all of them were pretty sure that Kayla was just messing with them. Joke around a little before the conversation could calm down, but a few of them did watch in suspense. Mainly Owen, Spencer and Harry who had already seen what Kayla was capable of.

The brunette looked so very hot in her short denim shorts and her colorful tank top, but she was feeling a bit nervous. She had known Kayla for a very long time, and knew that she could act a bit crazy at times. This was one of those times, she realized as she felt someone moving right behind her and a pair of hands slowly pulling down the straps of her tank top. Before she could react, it was yanked down enough for Alva's hefty tits to spill out.

"As most of you may know, these are tits," Kayla grinned as she groped the bare naked tits of her best friend right in front of their class. "A very beautiful pair of tits, actually. So very sensitive too, which is probably why she loves sex so much," The woman only seemed to add to Alva's reputation of being a slut, no matter how flustered her face was. Sure, she did love sex but she had never been exposed like this - it was definitely embarrassing, even if it was turning her on too. Well, Alva getting horny might have something to do with her nipples getting pinched and twisted by Kayla. Kayla continued rolling the sensitive little buds between her thumb and index finger, pulling onto them like she was trying to milk those udders...

There were mixed reactions amongst their classmates as Kayla was so very roughly playing with Alva's tits, showing them off. Some of them couldn't look away while others seemed very concentrated on averting their gaze, not sure what to do. Either way, most of them were starting to get really worked up despite being a bit off-guard. The sight of Kayla's fingers digging into the soft flesh of her friend's enormous tits was definitely turning them on, one by one.

"Can someone bring my bag, please?" Kayla asked sweetly, and within a second her bag was placed down next to her, on the desk in front of the class. She reached inside and pulled out a small black sex toy. It was just a few inches, almost like a pocket dildo that she apparently brought everywhere.

With one hand still on Alva's tits, she pushed that toy inside of the brunette's mouth. Almost in a reflex, Alva's lips wrapped around the thick toy and started suckling onto it, closing her eyes as she imagined she was somewhere else. How could it arouse her so much to get embarrassed like this? The more she gave into the public display, the more embarrassed she got... The more embarrassed she got, the wetter her pussy was getting! It was getting increasingly hot inside of the classroom as something so depraved was happening. "Good girl, make it wet," Kayla whispered to her friend, slapping those fat tits to make them jiggle. The praising only encouraged Alva even more, taking the dildo deep as she was drooling all over it.

Suddenly, Alva got pushed down over the desk - her bare tits getting mashed into the wood and her ass raised high. She felt how her button was opened and those shorts were tugged down, revealing her round asscheeks and the fact that she wasn't wearing any panties.

Her classmates were getting more and more into it too, encouraging Kayla to keep going. She was bathing in the attention at the cost of her friend, spreading her asscheeks to show off Alva's little star of an asshole and her pussy which was quite literally dripping.

"Either of these holes can get fucked, I'd imagine," The spoiled woman grinned, trying to keep up the act of giving sex education but that train had taken off a long time ago. She rubbed the tip of her dildo over Alva's folds a few times, getting it nice and wet thanks to the juiciness, before aiming it at her backdoor. The toy seemed perfect to invade her friend's anal cave, making her howl in surprise as the hole was stretched open nice and wide. "Fu-Fuck, Kayla," She moaned as she hadn't been expecting Kayla to go for that hole. She laid her head down against the desk, fully surrendering to the embarrassment of getting her ass fucked by her very best friend right in front of everyone she knew. She interacted with these people on a daily, and now the rumors of her being a slut were only confirmed. Clearly, it wasn't the first time she took something up the ass either.

Kayla began thrusting the thick dildo deep inside of her friend's ass, stretching her out so lewdly for everyone to see. She could see the horny looks they were receiving and grinned. She wanted to see who would dare to get involved.

"Anyone want to take over?" She looked back at the class, raising an eyebrow.

Most of the guys seemed to debate stepping up, but only one of them was brave enough to actually rush to the front of the room. His name was Thomas, and he was known to be a bit of a player. Typical jock with not a braincell left in his head, but he was confident.

Instead of taking over the dildo, Thomas pushed it out of the way and whipped out his own cock. It was slightly smaller than the dildo, meaning he could easily stick it into Alva's gaping ass - not even giving her any time to prepare or even realize what was going on.

"Oh my GOD!" Alva cried out as her head fell back, completely slumped over the desk as another thick rod invaded her backdoor. It felt so good now, as she had already been stretching out and that little hole wrapped tightly around Thomas's cock. He started thrusting himself home, fucking her from behind as her body bounced back and forth onto the desk.

It was actually hurting a bit, the way her ass was getting stretched and her tits were getting mashed down on the desk.

"I've been wanting to fuck this slut!" Thomas exclaimed as he spanked Alva roughly, properly pounding her from behind.

"Oh, she's not the only slut here," Kayla grinned as she had moved down to her knees right behind the jock, positioning the dildo that he had abandoned against his own forbidden hole. Just like he had suddenly penetrated Alva, Thomas would feel his ass stretching for the girth of Kayla's dildo, moaning out as he was now getting assaulted from both ends. His movements froze up for a second, but Alva wasn't having it - she needed to get fucked now, and started twerking her ass back against him. "Fuck! Fuck! Don't you fucking stop!" She cursed at him as she took his cock, while he was getting assfucked at the same time.

Several gasps could be heard coming from the others as they watched how the popular jock was suddenly getting dominated by two girls - one was fucking his ass and another one was fucking his cock. He groaned out deeply as Alva pushed back against him, creating such a lewd display...

With his ass being stimulated, Thomas didn't last very long. Barely a minute of just standing there in front of the classroom, being worked by the two popular chicks, and he exploded. "Fuck!" He cried out as Alva quickly let herself fall forwards, letting his rod slip out of her tight ass so he would just cum all over the desk in front. It would definitely make a mess, but the brunette didn't care as she hopped on top of that very desk, and spread her legs widely. She was hornier than ever before as two of her own fingers plunged into her cunt. Her fierce eyes were filled with lust and desire as she stared at her classmates while rapidly fingering herself, quickly bringing herself to the brink of climax.

She came hard.

Juices spewed out of her pussy, revealing to the entire class how much of a squirter she was. And truthfully, she felt more turned on than she was embarrassed. They could know. Every single one of them could take full advantage of how easy she got horny, use her body to get off as long as they brought pleasure to her as well.

As she watched her friend squirt all over the floor, Kayla grinned to herself. She had caused this landslide of an event, yet she was still fully clothed herself. She loved pushing people into doing the most perverted and depraved things. Her mother. Her brother and his girlfriend. And now, her best friend.

She would never get enough of it...
