Ariana could hardly sleep that night. She kept having nightmares about being Nicki's slave, constantly having her body compared to one she could only dream of having, and being forced to serve Nicki in front of everyone she knew. But the worst part was knowing how quickly she submitted. She couldn't stop thinking if Nicki was right, and this really was how things were supposed to be.

As she woke up from her restless sleep, she could feel a heavy weight on her chest, and as she opened her eyes she gasped in shock. Nicki was completely naked straddling Ariana, her massive ass just inches from the poor girl's face.

"I didn't want you to think it was all just a bad dream!" Nicki laughed devilishly, shaking her ass in Ariana's face.

"Please Nicki, I already admitted you were hotter than me, can't we just let this go?" Ariana pleaded. Kissing her covered ass was embarrassing enough, but having it naked in front of her face was downright frightening. She shamefully leaned forward and gave each cheek a quick kiss. "Your ass is beautiful, but please no more..."

"You might take longer than I thought to learn how to serve, but I'm sure I can whip you into shape by the end of this tour," Nicki said confidently as she sat her ass down on Ariana's face. Ariana kicked and screamed as her face was engulfed in Nicki's massive cheeks, but she was far too weak to make her touring partner move an inch. "And my name is Miss Minaj. Hopefully this time you won't forget it!"

"You know my fans would kill to be in your position!" Nicki laughed as she bounced up and down on the tiny girl's face. "The more you struggle, the more this is gonna hurt. So why don't you just admit that you're my property and lick my fucking asshole!" Nicki laughed as she made her demand.

Despite the hopelessness of the situation, Ariana refused to give in, continuing to try to squirm out from underneath the giant ass. She turned her head as much as she could to keep her lips away from Nicki's asshole, and her entire body shuddered in disgust at the thought of tonguing it.

"You're a feisty little bitch, aren't you? You're going to run out of air if you keep this up! I guess I can make it a little more interesting..." Nicki momentarily stopped her bouncing as she let out a loud fart right into Ariana's face. "Enjoy breathing that in, slave!" She laughed.

Breathing was indeed getting more and more difficult for Ariana as she worked herself up trying to get away, but this only got worse as her lungs were filled with Nicki's gas.

"You nasty bitch!" Ariana tried to yell, but the sound was muffled by Nicki's thick cheeks, and she just responded by giggling at the sound.

As Nicki continued her bouncing and Ariana felt herself getting lightheaded from lack of air, she reluctantly gave into her superior tour partner and stopped struggling. She nearly wretched as she gently touched the tip of her tongue to Nicki's sweaty asshole, but continued her disgusting duty as Nicki encouraged her.

"Good girl!" Nicki teased as she started groping Ariana's tits. "Isn't it much easier to just do as I say? Don't worry, in time you'll learn to love the taste of my ass..." Nicki giggled as she let out another fart, this one filling Ariana's mouth. "But maybe not anytime soon!" Ariana did not physically react to being forced to taste her fart, but all she could think about was how much she wanted to cuss Nicki out.

Nicki continued sitting on Ariana's face for several more minutes, rocking back and forth as she got off to having her ass licked. Once she was finally satisfied, she got up and looked down with a smile at the poor girl. Ariana just laid there, motionless except for her heavy panting as she tried to make up for the lost air. Her face and hair were covered in Nicki's ass-sweat, and looked up at Nicki with a blank expression in her eyes. She tried her best not to cry in front of Nicki, afraid that that might result in even more punishment.

"Wasn't that fun, slave? Just think, you'll get to do that for me every morning! And maybe a few other times during the day, depending on how dirty my ass gets I might need an emergency tonguing!" She said with a giggle.

Ariana was disgusted, but didn't have the energy to actually react try. "Thank you, Miss Minaj," she said robotically.

"I knew you secretly enjoyed it! You submissive little bitches are all the same. You act tough, but deep down you love nothing more than worshipping a superior woman's ass!" With that, Nicki turned around and presented her ass again, letting a final fart go in Ariana's face.

Ariana shamefully got up and leaned toward the stench and loudly inhaled to please her mistress. "Thank you, Miss Minaj," she said again, this time with more emotion as she tried to hide the fact that she nearly gagged.

Nicki just laughed as she left the little room, which had completely filled with the stench of her ass. Ariana broke down in tears as soon as she was alone, desperately using one of her blankets to wipe the mess from her face. This was only the second day of the tour, and it certainly seemed like Nicki was going to make the most out of their next two months together.
