Literotic asexstories – Erin’s Wild Week Pt. 03 – Biology Class by emelle78

Erin’s mind was elsewhere during her first two classes, but when she saw Amanda in the hallway she came alive. “Amanda!” Erin screamed, giving her a big hug, “I’ve been waiting to talk to you all morning!”

Boys in the hall paused, trying not to stare at the two lovelies. Erin felt a tingle from Amanda’s large breasts pressed against hers, neither of them wearing a bra. The two had hugged hundreds of times over the years but Erin’s body never responded with anything other than sisterly friendship before. This time, the feel of Amanda’s body was exciting.

Amanda pulled away. “How’s it feel to be a woman?” she teased.

“Fantastic!” Erin gushed.

“About time!” Amanda giggled, “you happy?”

“Oh, my God YES!” Erin replied, trying to keep her voice down in the busy hallway. “I can’t believe it! I lost my virginity and gave a blow job! It was amazing! I should have listened to you sooner!”

“I told you,” Amanda beamed. In a hushed tone she added, “did you swallow?”

Erin nodded, her eyes wide, as if she couldn’t believe what she had done.

“Did you like it?” Amanda pressed.

Erin nodded even faster, like a bobblehead doll. “I loved it! And he came a lot!”

“Oh, you little slut!” Amanda crowed proudly.

Just then the bell rang, signaling the start of third period. The girls ignored it, continuing their conversation while students slipped into their classrooms.

“Looks like we’re going to be late to Biology,” Erin worried, but this conversation was too important. “I guess I am a little slutty now,” she admitted, then her eyes narrowed. “Can you keep a secret?”

“C’mon, are you kidding?” Amanda responded, as if insulted. “Do you know me?”

Erin looked down the hall both ways, making sure it was clear. “I gave a blowjob to Noah Thomspon this morning,” she whispered. “In the parking lot.”

“What?!” Amanda hooted. “How? . . . what? . . . parking lot??”

Erin bit her lip. “I don’t know, it just happened. I was sitting in my car, thinking about last night, and suddenly Noah Thompson was there.” She thought for a moment. “He has a really nice cock. It’s big!”

“Wow, girl!” Amanda said in disbelief. “Sounds like the monster is out of the cage. You went from zero to slutty in a hurry!”

Erin laughed, shaking her head in disbelief. “Yeah, I think when Peter went down on me last night something changed. I can’t believe how good it felt!”

Amanda’s expression turned to surprise. “He ate you? Really? In the back seat?”

Erin shook her head enthusiastically, the look on her face saying can you believe it?

“Wow!” Amanda said, mystified, “I didn’t even know that was happening. It must have been while Bobby was fucking my brains out.”

Erin exhaled, “God, I can’t believe how amazing it was!”

“Hmph,” Amanda pouted, “none of the guys around here ever did that for me. Maybe you’ll let me borrow Peter one of these days?” she added hopefully.

“We’ll see,” Erin laughed.

Just then the Principal, Mr. Robinson, came around the corner. He was doing his usual post-bell sweep to herd stragglers to class, and when he saw the two young beauties he had to pause for a moment. My God! he thought, every boy in school must have a hardon today. Quickly, he composed himself. “Come on girls, get to class now!”

“We’re on our way,” Erin called as they sauntered off.

“Hey,” Amanda said when they were out of earshot, “what do you say we have some fun with Mr. Johnson today?”

Mr. Johnson was their Biology teacher. It was his first year and the students messed with him relentlessly. He was just a few years older than them and hadn’t yet learned how to control a classroom full of teenagers. They liked him, though, and it was all good-natured. Still, he couldn’t wait for the year to end.

“What do you have in mind?” Erin asked.

“Just follow my lead,” Amanda said as she pushed the door open.

* * *

Mr. Johson was standing at the board, giving instructions for the lab practical exam when the girls entered the room. Every student turned to look at the two gorgeous creatures striding in, completely disrupting his routine.

“Why are you late?” he demanded awkwardly, trying to restore order in his classroom.

“Ummmm, we were talking to Mr. Robinson?” Erin offered lamely. A few students chuckled.

“You two see me after class,” he said sternly, trying to set an example for the others. “We start promptly at the bell, especially when we have lab work to do. You should know that by now.”

“We’re sorry, Mr. Johnson,” Amanda said sweetly. “It won’t happen again. Promise.”

Mr. Johnson huffed, then continued, “OK, everyone, as you know we’re having the lab practical today. Specimens and microscopes are set up at the lab benches and you have six stations to complete. Understand?” The class groaned. “OK, I’ll take that as a yes. You can have five minutes to go over your notes before we start.”

The students pulled out their books and coalesced into groups to cram for the test, trying to learn in five minutes what they’d been ignoring for the past month.

Amanda made eye contact with Erin on the other side of the room and stood up, heading for Mr. Johnson’s desk at the front of the room. She cocked her head at Erin, inviting her to join in.

Erin nodded as she rose from her seat. What’s she got in mind here? she wondered.

Mr. Johnson looked up at the girls striding toward him. He struggled to fix his eyes on theirs, not allowing himself to scan their firm, young bodies. Nubilitos was the term he used in his mind to describe Erin and Amanda and some of the other senior girls. Their bodies were perfect, with smooth skin and tight curves. White teeth and bright smiles, luxurious hair, they had it all. They even smelled good.

But even though they were over 18 the Nubilitos were strictly off limits, morally and professionally. Every day he fought to maintain his focus – no wandering eyes, no flirty banter, no offhand locker-room comments to his male colleagues. It was a struggle, but so far he had managed to succeed.

“Yes, ladies?” he said sternly, keeping his eyes locked on Amanda’s. He looked to Erin, then back to Amanda. Eyes up! he admonished himself, don’t look down! Don’t succumb to the Nubilitos!

“First, we just want to say we’re sorry,” Amanda cooed, “we won’t be late again.”

“OK, apology accepted,” he said sharply. “Anything else? You should be using this time to study.” He could sense Erin’s nipples poking out from the blue dress but he desperately fought the urge to look. He felt his brow starting to sweat.

“One more thing,” Amada added as she dropped her notebook on the desk and leaned far over, allowing her top to drop down. The teacher now had a clear view of Amanda’s braless breasts, just a foot in front of his face.

Oh, that poor man! Erin laughed to herself as she watched him struggle not to look.

Mr. Johnson was painfully aware that Amanda was exposing herself. It wasn’t the first time it had happened. The Nubilitos felt a need to test him regularly, but he had always resisted. At this point in the year, though, his will was dissolving. There was only so much a man could take.

Mr. Johnson desperately battled the urge to look. He could feel droplets of sweat forming on his brow now, his face turning red. “I just don’t get this part about mitosis and meiosis? When the cells split and stuff?” Amanda complained, now resting her elbows on the desk and pointing at a scribbled page in her notebook.

“Can you check my diagram? Do I have it right?” she demanded, forcing the teacher to drop his eyes.

“Yeah,” Erin joined in, leaning over from the other side and pointing to another sketch in Amanda’s notes. “Is that transcription? It’s kind of confusing. Is that going to be on the test?”

Mr. Johnson now had two beautiful 18-year-old girls leaning half naked across his desk, ostensibly keen on learning about cellular functions. When he dropped his gaze to the notebook he simply couldn’t avoid the view. Their breasts were on full display, hovering over the notebook, right in front of his face.

He quickly scanned the room to see if the other students were aware of the lurid scene before him. A few boys were drinking in the sight of Erin’s and Amanda’s asses bent over the desk, while the rest of the class was scrambling to prepare for the test.

Mr. Johnson exhaled and gave in. As he reviewed the process of cell division for the girls he lifted his eyes from the page and took in the full vista before him. Amanda’s breasts were larger, he noted, probably a C-cup, capped with puffy pink areola. Her long blonde hair hung down, framing them as they jiggled above his desk. They were spectacular.

Erin’s breasts were smaller, probably a B, but perfectly shaped, like chocolate kisses, capped by hard reddish-brown nipples. They were so firm that they didn’t sway, not even when she moved her arms around. Her long brown hair cascaded down over her shoulders and spilled onto the desk.

There was no longer any point in pretending not to look, and the teacher switched his gaze from one lovely set of tits to the other as he explained the fundamental processes of life.

Mr. Johnson was incredibly aroused by the sight before him, four gorgeous breasts, close enough to touch, but he was mortified by his behavior and knew it had to come to an end. “Got it?” he asked, looking up at them.

Both girls were beaming at him, mischievous grins and sparkling eyes.

“Got it!” Amanda chirped, rising up and fixing her hair.

“Thanks, Mr. Johnson!” Erin chimed in, “I think we’re going to ace this test now.”

* * *

Mr. Johnson was darting around the room, answering questions, helping with microscope problems and making sure students weren’t cheating. At one point the class got quiet and Amanda raised her hand. “Mr. Johnson?” she called, “can you help me?”

The teacher gulped. He suspected Amanda was up to something but he had to maintain his cool in front of the class.

“Yes?” he said, standing at her bench but maintaining a safe distance.

Amanda pointed to her test and leaned forward. “Are we supposed to know this word?” she asked innocently.
