I'm grateful to the ball gag and the loud engines of the plane. Because there's no way I can stay silent as the turbulence causes my whole body to rock, which causes the vibrator and plug to thrust mercilessly into me. My clit is grinding hard against the vibrations, and I would have cum except the turbulence is making my huge breast bounce like crazy, and the pain from the nipple clamps is a terrible distraction.
I don't know how much time has passed, but the way my clamped nipples rub against my rough sweater fabric is driving me crazy.
Every once and a while, I feel Mistress discreetly slide a hand under my top. Every time I yelp from the surprise. She tugs the nipple clamp off, and she rubs the sensitive little nubs. I think of what she said in the airport: 'You're my entertainment.' After a few seconds of rubbing, she replaces the clamps, and I try not to whine.
With the gag and blindfold, I can't look to her and beg. What would I even beg for? To cum? Not to cum? For mercy? Mistress has never been merciful; it was one of the reasons I loved her. All of that begging would be useless. I was hers. Her toy to play with however she pleased. The only good my begging served was that it turned her on. But right now my purpose was to be edged and tortured repeatedly on a public plane for her entertainment.
I was so wet at the thought of it. I was practically sitting in a puddle of my own horny juices.
The headphones are playing the audio from one of our past scenes. I can hear her paddle as she smacked it hard against my ass.
"Listen to you. The noises you make when getting paddled are absolutely whorish," another loud smack. "Yygghhh!! Thank you, Mistress!" My words sound almost slurred and needy.
"Youre my little pain slut, aren't you?"
I don't reply. I remember still feeling ashamed at feeling so aroused by pain and not wanting to admit it.
As punishment for not replying, there's three more slaps: "Don't you deny it, you're as wet as spring rain. Now say it." Another slap, and I whine, "I am wet, Mistress. I'm your little pain slut. Please paddle my ass again!"
I'm so edged out of my mind that I don't even notice we were descending. I'm so lost in listening to that audio and the crazy sensations that I realize too late that I'm nearing an orgasm.
My natural reaction is to squirm to try and move away from the stimulation, but it only draws me closer! Oh no! No no no! I can't!
The plane hits the ground hard, and the orgasm is ripped out of me. I squeal behind the gag, and my whole body is shaking.
While I'm still in the throws of orgasm, Mistress pinches my clamps hard before yanking them off. She gently removes my headphones, and I'm suddenly aware of my own heavy breathing.
She leans in close to my ear.
"Tsk tsk tsk...bad girl. And you were doing so well. I can't wait to punish you when we get home."
I can't see her face, but I just know she's smiling.

It had been a few days since I had failed the near-impossible challenge my girlfriend/mistress had given me. I came without permission. And I had spent those last few days wondering when she would punish me. And how.
Now, she sat on the couch while I sat at her feet on the floor. My head in her lap as she gently stroked my hair.
