Bec squealed in frustration as Matt pulled the wand away. She had lost count of the number of times he had driven her to the edge, only to cruelly deny her release. She would eventually get it, but she did not know how many more denials she would have to endure until then. It varied from session to session, depending on how mean Matt was feeling.

Sorry for posting this one late and out-of-sequence. I did not realise until a couple of days ago that I accidentally skipped it here.

"I'm going to do another lap of the park. I'll be back in a few minutes to untie you. Try not to cum before I get back~"

Erin ran off down the track, leaving Lucas to struggle not to succumb to the wand. The blindfold over his face served to maintain the illusion of the scene by preventing him from seeing Erin stop after a few metres and sneak back to lean against a nearby tree.

Of all the events at the Bondage Games, the marathon was considered the most gruelling. Erin prided herself on her fitness, which was why she had decided sign up and test herself. Two hours in, sweat was pouring off her body, as she drooled around the hard plastic ball in her mouth.

The collar acted as a tracker and motivational device, ensuring competitors stayed on track and maintained a minimum pace between checkpoints.

An artificial voice came through her earbuds. 
"Speed unsatisfactory. Administering motivation."

She accelerated, but was too late. She yelped as her collar beeped and then gave her a small shock.

Allison Ross was not particularly fond of running, or exercise in general, yet she had for some reason agreed to be Erin's partner for this "Bondage Cross-Country" event. That was why she found herself running behind her friend and lover while gagged and with her hands balled into fists and taped up. The latter, she had learned, was to prevent competitors tampering with the "motivational devices," the effects of which she had experienced multiple times during the course of the event; the vibrator had driver them both to orgasm twice as a reward for finishing some stages in good time, while the collar had punished them for falling behind, and also drifting too far apart. The latter was why she now made sure to keep pace with Erin, even if she struggled sometimes.
