The sun was starting to rise over another clear day. The trees were covered in cherry blossoms. It was springtime once more. Twilight groaned and rolled over in her bed before her alarm went off. 6:30am. She groggily turned off the alarm, sat up and yawned. She turned on her phone. June 23rd it read. Graduation Day.

Twilight got out of bed with little fanfare and walked to her kitchenette. Today was a big day so she made a big breakfast: two Sunny Side up eggs, vegan bacon and two toast slices with strawberry jam. As she finished up, she put the dishes in the dishwasher for later, grabbed her backpack with graduation robes and cap tucked neatly inside, and left her apartment.

8am

Twilight made her way to the designated women's changing room (or the currently unused art room on the first floor as they knew it as) for graduation later that day. She pushed open the door and saw four of her friends: Rarity, Pinkie, AJ, and Fluttershy. “Girls, am I glad to see you.” Twilight set her backpack on a desk.

“Twilight, Darling. How was the break? Spend some quality time with Taylor?” Rarity inquired. Twilight blushed a bit at that but quickly recovered.

“We did indeed have a great time. In fact, I have some news to share.” Everyone perked up though Rarity, ever the gossip hound, lit up. “Taylor and I talked it over and we decided to move in together over the summer. I'll also because a full-time tutor with the hope to one day become a teacher.” They clapped in approval.

“Taking that next step. Mighty great, Twi.” AJ praised and nodded. “Since we're talking about immediate futures, I got somethin' to say too. Granny has been getting up there in years. We talked it over and decided I'll be taking over daily farm operations soon…by harvest season at the latest.” Pinkie went up and hugged Applejack.

“There she is. Our farm girl has grown up.” Pinkie exaggerated shedding tears. “If we're talking about our plans going forward, boy am I gonna be exhausted. I'm starting a party planning service.”

“Don't you already throw parties?” Twilight interrupted. Pinkie put a finger over Twilight's mouth.

“I know but this is WAY bigger. Until now, I've been fairly local and only go to the surrounding towns for parties but now, I have some new wheels.” Pinkie shows them a photo of her new party van. It was pink and light blue all over with confetti either stuck on, painted on or both. The words ‘Pinkie’s Party Service’ adorned the sides along with her business phone number. “Now I can go wherever I'm needed.” Twilight nodded in approval, impressed at how much thought Pinkie put into this.

“Oh uh girls?” Fluttershy spoke up. “It's nothing that impressive but I'll be working full time at the local animal shelter that has a sanctuary in the back. I'm hoping to make one of my own or take over after Mr. Dolittle retires.” Everyone smiles, happy to see her future looking bright.

“I suppose that leaves me. As you already know, I got offered a fashion scholarship at Style U. You'll be happy to know I'll be taking that scholarship though I'll be staying on campus two states away for a year. But once I graduate, I'll come back and open my first boutique. Girls, you'll be first in line.” As Rarity finished, everyone felt a sense of relief and calm rush over them. Saying their plans for the future and knowing how supportive their friends are was a major relief for everyone.

“Come on. Don't forget about me, girls.” They heard a familiar voice outside the room.

“Rainbow Dash? Where have you been?” Twilight asked.

“It's kinda a long story but I also have something to say or…more like show you guys. You gotta promise not to freak out.” She half-joked. They looked at each other a bit apprehensively but nodded.

“Ok. We promise.” Dash opened the door as Twilight continued. “You're our friend no matter wha- SWEET CELESTIA WHAT HAPPENED TO YOU?!?”

Rainbow Dash, the young woman who was once just barely bustier than Twilight, now had breasts the size of overfilled beanbag chairs and that was only scratching the surface. The bra alphabet wasn't enough to describe her anymore. Her tits were barely contained in her graduation gown. Twilight noticed her nipples through the fabric. They looked to be as big as tires on an ATV. Dash's breasts weren't the only difference as Twilight looked behind her and saw that her once waist-length hair now flowed very long and thick to the floor and surrounded her back like a fluffy cape. Everyone was speechless though Pinkie was about ready to explode rocking back and forth. "It's ok, Pinkie. You can tell them now." Dash reassured her. Pinkie inhaled tons of air before speaking.

"SOOOOOO...I kinda already knew Dash had hyper titties since three days ago." They looked at her in disbelief. "Dashie asked me to get some groceries and bring them to her place. Before I could leave them on the porch, the front door was unlocked so I let myself in only to see her sitting on the couch sleeping. I screamed waking her up and we talked for a bit. She asked me to promise not to say anything until she showed up today and now...here she is. World Record Holder for Biggest Boobies: Rainbow Dash." Pinkie presented Dash with jazz hands. Rarity and Applejack slumped into their chairs, Fluttershy fanned herself off, Pinkie went back to change into her gown and Twilight just stared in awe.

"How the hell did this happen?" Twilight tried to question.

"Honestly, I don't know myself. I guess maybe the best guess is my new boyfriend started massaging them before, during, and after we go at it." Fluttershy nearly fainted considering how much sex that implied. Twilight, being a very rational and level-headed woman, decided to completely ignore that explanation if you could call it that.

"And here I thought you were padding your bra for the last two years. Guess you showed me." Applejack interjected. Rarity faintly raised her hand as if to say 'I thought you padded your bra as well.' As the room descends into silence once more, Rarity's brain finally catches up with what Dash said.

"YOU HAVE A BOYFRIEND?!" Dash nods smugly. 'There it is.' She thought. Twilight, trying to get back to the topic before Dash busted her way into the conversation, looks at her.

"So...what are your plans after graduation?" Before Dash can answer, the intercom goes off.

"This is Principal Celestia with an announcement. It is now 30 minutes before the start of the graduation ceremony. Students are to begin heading to the auditorium as soon as they are able. A 5-minute grace period will be allowed for latecomers but all those who arrive after the doors are locked will not be allowed to participate in the ceremony and your diploma will be mailed to you next week. See you at the auditorium." Dash looks at Twilight, puts on her graduation cap and steps into the hallway.

"I'll tell you guys after I actually get the dang diploma." She speeds off surprisingly fast with her new assets. Twilight sighs and closes the door.

That is the story of Twilight and Taylor, the couple who started as student and tutor, became friends with benefits and eventually lovers. What a happy couple. But what of Rainbow Dash? Who is her new boyfriend? Did he really cause her breasts to swell to hyper levels? Was Dash really padding her bra for two years? What of her rapunzel-length hair? These are questions for another time. Until then, goodbye for now.

Author's Note

With that, Male Chemistry is finished...at least the main story. A side story with Rainbow Dash and her new BF will be made sometime soon hopefully.

Thanks for reading. So sorry it took so long to finish.

Have a good day.
