Heat in a Bottle

Thud, thud, thud. Thud, thud, thud.

Big Mac sighed as the images of last night still plagued his mind. He knew plenty of couples who wanted to have foals, but how does someone offer something like this? Oh hey, I can get your wife to bang you and give you a child. He groaned at the thought, deciding he needed something else to do.

Apple Bloom’s always energetic. We might scold her, but she might just be what I need to forget and think straight. As he approached the barn where she was supposed to be feeding the animals, he heard her crying in agony. He ran to the door and slammed a hoof into it. No one is hurting my baby sister!

However, Apple Bloom wasn’t acting like a baby sister as he saw her. She was showing off her eighteen year old figure, complete with fingers that attacked her drenched pussy. He locked eyes with her and she said, “I’m scared.”

Big Mac took a step back as his cock became rigid in his pants. He glanced to where he had stashed the case and could see it wasn’t there. Instead, the bottles were on a hay stack with one completely drained. He stepped back as Apple Bloom spread her legs. “Please, help me.”

A few strides was all it took for Big Mac to close the distance between the two of them. She was quickly taken into his arms and he whispered, "It's okay," into her ear. He could feel every feverish shake of her body as the potions effects ravaged her innocent body. Even when Applejack knew what was coming at twenty-one, her first heat... His mouth became dry as he remembered hearing her sisters moans for the first time. The first time was supposedly the hardest on a mare, and if she drank the whole thing, one could only imagine the pain she must be in.

Apple Bloom curled into his chest as tears came down her face. "Big brother, please, I need you."

"Do-don't worry. I'll get you help." His voice jumped almost a full octave as Apple Bloom's hand stroked his massive crotch through the fabric. "You ca-can't do that."

"I-I didn't. It was my body." She gave out another spasm and he felt a gush of liquids against his thighs. Her eyes were almost glazed over and her hand simply wouldn't stop grinding at her and his crotches.

For a moment he considered leaving her. He could get Applejack or Granny and they could help her. Big Mac's let out a forced grunt as his cock twitched in pain. It also caused him to take in the full force of her pheromones and his body tensed as an almost overwhelming need came over him. He tried to shake it off, but his instincts sought a reason, any reason, to fuck his sister. Soon the image from last night was in his mind, but instead of Suri being on stage, it was his little sister and some mystery colt. All because he let her have a chance to find another to be fucked by while he went to get help. A single tear ran down his face as he made a decision. A big brother protects their little sister, right?

He took in a deep breath while he steeled his nerves and dropped his jeans. Apple Bloom’s eyes went wide as she stared at the revealed monster. I always knew it was big, but that… that’s finally going. Apple Bloom couldn’t contain a moan of lust as she fell against the crate she had been sitting on.

Big Mac thanked that she had closed her legs with the action and he quickly covered the distance between them. He swallowed hard as he stood over her and her perky C cup breasts. He couldn’t help but remember the days when they bathed together when she was a filly. Memories that would now always be tainted by this act. Perhaps this is my punishment for not having been more careful with the bottles? “I’m sorry. I-I'll try to be gentle.”

Apple Bloom opened her mouth in another lewd moan and shivered as strong, calloused hands came over her breasts and squeezed her nipples. "Th-thank you."

The words felt like spikes through his chest, but he pushed the pain away. Big Mac wanted this done as quickly as possible, but he just didn't have the heart to simply stick it in her without showing that he cared. He took one hand off her bosom as the other gently covered the mound and started to message it. His off hand wrapped around her and pulled her up so he could start gently licking and nibbling on the other exposed breast. He slowly moved his way up to her sensitive pink node and clasped his lips firmly around it.

Apple Bloom’s eyes filled with tears as she cried out, “Stop teasing me!”

Big Mac glanced up and felt pain go through him as he saw the desperation on her face. Only since I must to protect her. He put her back down on the crate before forcing her legs apart. He noted the puddle that had already formed and quickly started fingering her. The folds grabbed ahold of each finger, each wanting more then the last. However, he only did this for lubrication, not foreplay.

She licked her lips as Big Mac stroked her fluids onto his cock. Her pussy was more then ready, or at least she hoped so seeing as his cock was bigger then any textbook had led her to believe they could be. He leaned over her and she felt his hot breath against her face and finally she turned deep crimson as she realized what he had planned to do. Could I really be doing this?

Big Mac stared into her orange eyes. If he was going to take her virginity, he was going to do it the only way he knew.

Apple Bloom put her head up and opened her mouth. Only a few more inches. She could almost taste him when–

“Big Macintosh!” Applejacks stormed across the room, her button up shirt showing plenty of her double D cleavage and allowing them to bounce. “What in tarnations are you doing?”

Apple Bloom put an arm on Applejack’s arm. “It isn’t his fault. I drank something I really shouldn’t of and I guess this is part of the consequences. He didn’t have any other motives than to help me, I swear.”

Applejack took in a calming breath as she turned between the two of them before sighing angrily. “Big Mac, is that true?”

Big Mac nodded before his head simply hung there. As tears fell from his eyes, she turned back to Apple Bloom. “You and I are going to the psychiatrist first thing tomorrow. As for him, we’ll talk later. However, maybe I can...

Apple Bloom was whimpering as she stared at Big Mac before Applejack’s hand dove into her pussy. It wasted no time as it found her G spot and brought her straight back to nearing climax. She tried weakly to help Applejack get off as well, but she was overtaken quickly by her skill. Or at least she would have if Applejack had touched her like Apple Bloom wanted her to.

Instead, Applejack had place her hand upon her stomach. “Did you-”

“Of course not.”

Applejack nodded and turned back to her sister. “Go up to your bedroom now.”

“But I need-”

“Go to bed, Apple Bloom!” Applejack watched as her little sister stumbled upstairs but then turned to the real culprit. “Why?”

Big Mac held the empty bottle of ‘Heat in a Bottle’ up to her.

“You hid this because of common sense, right?”

“Eeyup.”

“And then she found it unknowingly?”

“Eeyup.”

“And does this cause fertility?”

“Eeyup.”

“And you didn’t want another stallion finding her and abusing her, right?

“Eey–” The wind was knocked out of him as Applejack hugged him tight.

She sighed as she pulled away. “Thank you then, Big Mac. Anypony else and I would have had them castrated. You, though, I know getting her pregnant would have been the last thing on your list of to do’s. However, you have to do something for me tomorrow as repentance.”

“Anything.”

“Get this,” Applejack said as she picked up another vial, “tested by Nurse Redheart. Listen to everything she has to say and don’t come back until you know whether or not this could hurt Apple Bloom or any other pony. Understood?”

Big Mac nodded, happy to have a clear direction for the item. He turned away from his sister and immediately blushed hard as he realized that she must have seen it. Think about anything else other than her. He lost himself to fantasies about Nurse Redheart as his cock ached for want of pussy instead of hand.
