Kim and Seb, a sub couple in an bdsm open relationship

The story follows Kim and Seb, a submissive couple. They were in town for a BDSM convention and visiting their dominants. They were into couple bondage, cuckolding / cuckqueaning, long term chastity and findom. Unfortunately, a series of bad decisions led to this punishment by their dom, who made them enter the casino.

Kim and Seb were both 20 year olds. They were childhood sweethearts and came from well-to-do families. However, both realized that they were submissive. After a period of unsatisfying sex and experimentation, they decided to open their relationship and enter a long-term power relationship.

Kim was wearing a bright yellow bikini with pink edges. It was skimpy even for a bikini at the beach. In the luxurious casino, it was bordering on lewd. The bikini top barely covered her perky breasts and provided no support, causing them to jiggle with every step. The thong framed her ass perfectly and showed off much of her inner thighs.

Seb was also wearing a yellow speedo, which only managed to cloth his cock in a soft state. Being a surfer, his toned muscles and suntanned body was left uncovered for all to see. As he entered, the blast of cold AC caused his nipples and cock to be half-erect, and his bulge strained against the tight speedo.

Both Kim and Seb were wearing thick black collar, indicating their submissiveness.

A round flying done approached her and scanned their faces.

"Kim and Seb. A submissive couple. Welcome to All In Casino!" the drone said.

"He..hello," Kim stuttered, impressed and nervous by the technology.

The drone handed them neon pink cocktails. "On the house!" They took a tentative sip, then gulped it. It was sweet and delicious which masked its strength. Unknown to them, just a sip made themtipsy. It also contains nanobots which could potentially control their hormones.

The drone said "Since it is your first time here, you may want to refer to the rules.

Also, it is costing each of you $1 per minute to be here. Interest is accrued at 0.001% per minute. You already owe us $10 - after all, oxygen isn't free! Now, go have fun!

We have a coinflip game to let you earn $200. Would you like to play?"

They were shocked to already in debt! Seb asked, "Is the game rigged?"

"Not to worry, our games are never rigged," the drone replied. "I'll flip a coin. Heads you win $200. Tails you lose your dress. If you decline, please pay the $12 you owe. Unfortunately, you will be blacklisted."

Kim was ****. The game didn't sound too bad either. "Ok, we'll do it!"

The drone flipped a coin. It landed on...
