Mackenzie receives a wake-up call

Mackenzie blinked twice as her mind drifted from dream to reality. It's been a long night, punctuated with vivid dreams, and she was horny as fuck. She was wet, her ass was sore, and she suddenly realized that what woke her up was a faint vibration between her legs. Fuck. Must have fallen asleep with her vibrator. Again. "Dumbass", she muttered as she reached down to get rid of the intruder.

Touching hard metal brought a sudden shock and she pulled the blanket away, looking down. The memories of the day before came back rushing, and suddenly she remembered it all: her naked adventures, the way in which Rachel and Marianne humiliated her, and the cruel way in which the two punished her. She had not only been denied the release that she craved so badly, but she also got locked in this diabolical belt.

And now this. It didn't take too long for Mackenzie to figure out where the vibrations came from. To prevent chafing, the belt had a bumpy silicone cushion that hugged her pussy and mound, sitting snugly against her clit. Normally, it would go unnoticed, but now it throbbed and buzzed, sending chills up her spine. She was already aroused and this didn't help.

Buzz. The vibrations became suddenly more intense, and dropped right after, causing Mackenzie to close her legs instinctively. Her nipples were rock hard. Buzz. Buzz. Buzz. The jolts kept coming, exasperatingly. She exhaled, trying to keep things under control, which she clearly didn't have, and arched her back, frantically rubbing her nipples. The belt kept tormenting her, holding her at the edge of an orgasm that just wouldn't come, until it suddenly stopped, leaving her empty and frustrated.

Buzz. It wasn't the belt this time, it was her phone. Rachel was calling and Mackenzie heart sank again. It couldn't be a coincidence. "Good morning, sleepyhead. Did you enjoy your new alarm clock?" "What the fuck have you been doing, Rachel?" Mackenzie's voice was both fearful and angry. "I just found out this app for your belt ... " Unlike Mackenzie, Rachel was smug and oddly excited, and Mackenzie's thighs shut down hard again as the belt vibrated briefly. "It has all kinds of features. Intensity, duration ..." The sensations changed to a steady, low thrum. "It even locks and unlocks from here."

"Please, Rachel... stop ... " Mackenzie turned plaintive, practically begging, but Rachel ignored her. "Nah, Kenz. This is too much fun. See you later!" Another light buzz and the belt went silent as Rachel hung up.
