A/N: I apologise if this chapter is boring to some. I recommend you read the whole thing because it is quite compulsory to the story. I also apologise if it doesnt make much sense since I'm terrible when it comes to making plots and storylines.
Tails couldn't remember what happened or how he ended up here. All he could see was darkness. He had just regained consciousness. Although he couldn't see, he could feel he was on a cold table. He daren't move, in case someone or something else was in the room with him. He wanted to make sure he was safe first.
"Oh, you're awake, dear," said a familiar female voice. Tails recognised it instantly. Seconds later lights came on and he found himself in a labratory of sorts laid on a desk. Vanilla was stood, watching over him. Despite the fact that she was the only other person in the room he could see, he could feel another presence. A familiar one. Hiding in the shadows. The room was rather tall and he couldn't see the ceiling due to poor lighting.
"Thank goodness you're okay, dear," said Vanilla, smiling sincerely. "I really apologise for the methods used to bring you here. My apprentice here came up with that idea.
"What apprentice?" questioned Tails, full of questions.
"This apprentice, cutie," came yet another familiar female voice. Then, from the ceiling swooped Rouge, her breasts shaking when she landed. "Nice to see you again, Tails."
"But why did you two kidnap me and bring me here?" asked Tails, demanding answers. "Actually, where even is here?"
"This is the school basement," explained Rouge. "No one comes down here because only us working in this department are allowed. No one else in the school is aware of our operation."
"It might take a while to explain why we brought you here," said Vanilla. "But you're a smart kid, Tails, so you should grasp it rather quickly. We have been monitoring your activity here at Green Hill Academy."
"Monitoring?" Tails didn't feel comfortable that teachers were keeping track of everything he was doing.
Vanilla nodded. "We wanted to see which males who attended the academy are BDMs, and which ones of you are not. It appears you are one of them."
Tails was confused, having never heard the term before. "A BDM?"
"BDM stands for 'Big Dick Mobian'," explained Rouge, smirking. "It's easier to say BDM for short."
"B-but what are they? Why do you want to keep track of them?" questioned Tails.
"Let me explain," said Vanilla, wanting to calm down the fox. "Big Dick Mobians are mobians with abnormally larged penises for their age, such as yourself. You are only 12 years old, but your penis is larger than most adult males." She paused, and Tails watched her glance at his crotch area. He was thankful his clothes hadn't been removed. "It is unknown how Big Dick Mobians came to be, since there is no sign of it coming from heritage or diseases. One of our aims here is to investigate the origins of Big Dick Mobians to develop a better understanding of them."
"Is that the only reason you brought me here?" asked Tails.
"Not the only reason," interrupted Rouge suddenly. "We have a mission here to accomplish, but we need the help of a young, healthy Big Dick Mobian to do it."
Tails blushed, feeling as if that was a compliment. "Y-you picked me."
"Of course," replied Vanilla. "You're the perfect person for the job. Only if you are willing to help us of course."
"I don't even know what you are doing, and who is this 'we' you keep talking about?" asked Tails, a little annoyed now.
"Oh, how rude of me," said Vanilla, giggling. "We are the 'Green Hill Academy Sex Research Team', and our sole mission is to use Big Dick Mobians to impregnate young women to create some kind of crossbreed."
Tails realised what they were implying and was quite shocked by this. "Y-you want me to breed with people? Like a guinea pig?"
"It's fine if you don't want to help us dear," said Vanilla in a motherly voice. "We understand you may not be comfortable with it."
"But why would I want to help you?" asked Tails.
"Because we believe that this could help understand our knowledge of Big Dick Mobians," explained Vanilla. "By doing this we can change society and make Big Dick Mobians something to be proud of."
Tails was about to say no but then thought. If this can change to help people like me, it could be a worthy cause. I really want to change the world. It's a reason I came to the academy. This could be the first step to doing that!
"I'll think about it," said the fox, delighting the busty women before him.
"Wonderful, Tails," said Vanilla, happy that Tails had accepted her offer. "Thank you for at least considering the offer."
Tails nodded and began to think for a moment. Vanilla smiled and said "we'll leave you alone to think about it."
"Thanks," he said as the two left the room, slightly showing off their asses.
Tails was sat there thinking about his choice. But what if this goes wrong and I end up being the father of hundreds of mutant babies. I don't even want to think about that!
His thoughts were interrupted a few seconds later when Vanilla reentered the room. "Have you considered the offer yet, Tails."
"I'm still thinking about it," he replied.
Vanilla sighed. "Why don't I do something that may persuade you to join us."
"Um...okay," he replied, not sure what to expect. Then, to his shock, Vanilla pulled her shirt open, allowing her enormous breasts to flop out. Before he could question her answer she pulled his face into her tits, leaving it buried in the enormous exposed cleavage.
Immediately Tails' penis started to stiffen and Vanilla could make out a tent in his pants. "Relax dear, let me take care of you," she said, rubbing his back. She could feel him relax between her breasts and could tell he was actually enjoying it.
He must have been sat there for a couple of minutes, head surrounded by the two fleshy mounds. Eventually he had to pull away to breath. "Did that persuade you enough, dear?" asked Vanilla before buttoning her shirt.
Tails wiped away some drool that had formed on his lower lip. "W-well..." He thought about it. The fox wanted to do this to help people, and he also got to hang around with these beautiful and oddly sex-obsessed people. He finally came to a conclusion, one which he thought to be most sensible.
"I'll do it," he said, making Vanilla smile rather excitedly.
"That's brilliant, Tails!" she said, clapping her hands together. "Let me introduce you to the others and explain more about what you will be doing."
She left the room, Tails following her, his dick still hard due to the sight of her shaking, jelly-like rear. They entered a small corridor before coming into what appeared to be some kind of lounge where Rouge was sat on a sofa, legs crossed. Sat in an armchair, to Tails' surprise, was Doctor Robotnik, his science teacher.
"Doctor Robotnik?" he gasped, rather surprised.
"Ah, Tails," he said with a bit more enthusiasm than he spoke to other students. Being smarter than his classmates, Tails appeared to be one of Robotnik's favourites since he didn't act as immaturely as the other 'brats' which were Tails' classmates. "So you're the BDM subject I was told about."
"I thought only women were working with you," Tails said, speaking to Vanilla.
"Doctor Robotnik is a leading teacher in science, and an expert in all three sciences," explained Vanilla.
"This means Doctor Robotnik understands biology, so he knows all about reproduction which helps us understand BDMs more," added Rouge, who Tails felt staring at his crotch. He realised he was still hard and the bulge in his pants was visible, so he tried to cover it with his hands.
Tails looked over and saw another woman standing in the corner. It was a purple swallow who was rather busty like the others. While she wasn't as big as Rouge, Vanilla or Amy, her cleavage was still rather impressive and was exposed due to the outfit she was wearing. "Um...hi," he said with a small wave.
"You ask us to work with a healthy mobian and come up with this guy?" muttered the swallow. "He's pathetic."
Tails felt rather insulted by the comment and was about to reply but Rouge did for him. "You haven't seen the kid in action, Wave. Definitely don't underestimate him."
"That over there is Wave the Swallow," explained Vanilla, gesturing to the swallow. "She's in her last year here in the academy and is a technology expert. She builds all our inventions, such as the smoke grenade Rouge used on you and the tracker she planted on you."
"What?" Tails had never even known Rouge had put a tracker on him. She must have done it when she invited him into his office. It explains how she knew where to find him in the trees before she kidnapped him.
"I don't want us getting off on the wrong foot," Tails said to Wave. "So can we get along?"
"Whatever," muttered Wave, clearly not too thrilled about Vanilla's choice of BDM.
"So what will I be doing here?" asked Tails, looking up at Vanilla. His dick was soft again now so he didn't have to cover it.
"You are here to reproduce with multiple members of the academy," explained Doctor Robotnik, standing up. "Due to the students here being supernaturally gifted, we have some subjects that are more likely to survive reproduction with a BDM."
"W-what?" gasped Tails, frightened that there was a possibility he could kill someone.
"A normal mobian hasn't been tested on, and it is unknown if they will be handle to the length of a BDM's penis and what it releases," explained Robotnik. "But a gifted mobian, however, definitely will survive."
"Thank goodness," whispered Tails.
"You will breed with multiple students to create crossbreeds that will likely be giving unique properties due to having a unique mother and father," continued the doctor.
"That seems like a big responsibility," pointed out the fox, rather afraid of what he was doing but at the same time excited.
"Are you sure you want to do this, dear?" asked Vanilla, seeing Tails slightly uncomfortable.
Tails nodded. "Yes, I want to help."
"Wow, the shortie actually wants to do this," muttered Wave. "He must be a huge pervert."
Tails ignored the comment and looked at Robotnik. "So what am I supposed to do now?"
Robotnik grinned. "Well, you have to breed with your first partner."
"Oh," said Tails, surprised he didn't have any training or anything to do first. "Who is it?"
"We want to start simple so we chose a subject of the same species to start with," said Robotnik before a screen lowered down. He picked up a remote and pressed a button, showing the image of a familiar fox Tails met on one of his first days at the academy. "Fiona Fox."
