As she fed Angel a bowl full of carrots, Fluttershy heard the cottage’s doorbell ring. The yellow pegasus turned her head to the door as she stood and walked over before cracking it open and peeking out. She looked around but saw no one there but a small package sat on her doorstep with the words “Open me!” written on the top. The pegasus was curious as to who left the box but she shrugged and picked it up before taking it inside and to her room. Fluttershy opened the box to find a white cassette sitting in it with “Play me!” scribbed on the top in red ink. The female grabbed her headphones and cassette player from her nightstand, slipping the headphones on her ears and popping the cassette into the player then pressing play. Once the tape started rolling, a soft voice could be heard along with some psychedelic music.  
“Listen to my voice,” the tape spoke into her ears, “for it is now your master. You will listen to my every command.” As she listened to the voice, Fluttershy began to lose herself and draw away from reality as her pupils began to turn as blue as her corneas. “Strip.” The voice spoke. Fluttershy stood up and began to take her shirt off, raising it over her head as her bra caught her huge tits as they fell back down. The pegasus slowly stripped off her shorts and panties before raising back up to fiddle with and remove her bra as her huge breasts were released and exposed as she returned to sitting on her bed.
