Birthday gas

It was my birthday tomorrow. He was the one human in all of equestria. Pinkie Pie was talking to me, when she asked what I would like for my birthday tomorrow. I made her pinkie promise not to laugh, think what I want is weird, and not tell anyone unless I say so. After she promised, I told her that I wanted a few ponies of my choice to go into a private area, and have them fart for me. Pinkie Pie just responded by saying okay. She put her mouth up to my ear and burped. She smiled bigger and mentioned that she had been gassy today, and wouldn't mind going somewhere privet to fart. I accepted the offer, and she took me to her bedroom at Sugar Cube Corner. She closed, and locked the doors. She told me to sit on her bed. Once I did that, she walked over to me,  and turned around. She slowly raised her tail. "Careful, I may go off without warning" Said Pinkie Pie. After a few moments, I saw her butt-hole go out, just as I heard a fart that was like a combination of an airy fart, and a bassy fart. It was loud, and lasted around three seconds. "Hey, I'm about to fart again. Want me to do anything different this time?" asked Pinkie. I simply responded by putting my pointer finger to her butt-hole. She released a loud, crackling fart. It felt nice on my finger. "So, you like your present so far?" questioned Pinkie, to who I responded yes. She asked for a list of the ponies I wanted to fart in order. I wrote down the names

 "Fluttershy, Rarity, Twilight Sparkle, Applejack, Rainbow Dash, Derpy Hooves, Cutie Mark Crusaders, Princess Luna, Princess Celestia, Princess Cadence, Octavia, Vinyl Scrach, Lyra, Colgate, and Pinkie Pie"

 She took the list. On the day of my birthday, I arrived early. I was so exited for Pinkies present. After the all the guests arrived, I asked Pinkie how she was going to get them gassy, and willing to do it. She grabbed fluttershy, and brought her in a big, lit up, empty closet. She explained to Futtershy, about my gift, and left. Fluttershy blushed, as her stomach growled. "You're 100% sure about this?" Fluttershy asked. "Yes" I responded. She lifted her tail, and one of her hind legs. She grunted, until a four and a half second long, airy fart came out. This only made her blush more. "It's OK, fluttershy. I won't tell anypony else about this" I assured "You won't?" she asked "I promise" I said. After that, she let rip. Unfortunately, she used all her gas up quickly. She left, and brought in rarity, saying that I needed her.
