Mistress Mona has suspected that Her human furniture sl*ve has been cheating while serving as Her face chair, moving its face out of Her *ss cr*ck, making it far less comfortable and relaxing for the chair's Owner. So She has decided to train the recalcitrant sl*ve someplace where the inferior m*le cannot possibly find a way out of its responsivity to serve its Owner first.

Mistress Mona rocks a hardly there, super-sexy micro-bikini, that doesn't really cover much of Her gorgeous camel-toed p*ssy and silver-dollar sized nipples, highlighting Her petite but long and lean body. The sl*ve wears a blinding hood, unable to enjoy the charms of its tormentor and Owner. It also wears a white plastic hobble chain that connects its wrists and ankles together, making it easy for Mistress to control. She fondles the chain while talking to the sl*ve:

"You know, I think you've been cheating during your face chair training and sneaking some breaths, and you should be up to 2 minutes, but you're not close to that. So I decided to try something different"

"Like what, Mistress?"

"LIKE THIS!"

She suddenly yanks the sl*ve's hobble chain straight up, pulling the sl*ve off of its feet and its head underwater. It screams in surprise, sending a barrage of bubbles up to the surface as the sl*ve falls to the bottom. She holds the chain high for 10 seconds or so, then lets the sl*ve up, gasping and sputtering, asking Her why She did this?

"This is a continuation of your breath training as a face chair. But you can't cheat underwater!"

The sl*ve tells Her it wasn't cheating, so She just pulls the chain up again, sending the sl*ve to the bottom, but this time She steps onto the sl*ve's chest and stomach while it's underwater, pinning the sl*ve to the bottom and pushing the remaining air in its lungs out. She keeps the sl*ve underwater for over 40 seconds, and when She lets it up, it is wheezing, coughing and whining that it hadn't cheated before.

"Yeah, yeah, yeah, well, we're gonna find out! Sorry, I kinda forgot to count, but you get it, right? Now say 'thank You Mistress, thank You for my training'"

As soon as the sl*ve utters the words, She pulls up the chain again:

"Ok, its back underwater you go, b*tch"

She pulls the chain, the sl*ve sinks to the bottom but this time She straddles its body with Her knees, pinning the sl*ve but in a more comfortable way for Her *ss. While the sl*ves lungs are b*rning and it starts shaking, She just giggles at its struggles and calmly pats the sl*ve's head underwater, like the good pet that it is. After a full minute, She allows the gasping, coughing sl*ve up. She reminds the sl*ve to thank Her, and when the sl*ve asks how long She kept it under, She says:

"Oh, I'm not sure - I wasn't really paying attention. Maybe 30 seconds or so"

The sl*ve is disappointed, thinking it was much longer, then starts complaining that the training is unfair. She just answers by pulling the chain straight up. She steps onto the sl*ve's body while underwater and poses, walking up and down its body like a runway. After another brief rest, She dunks the sl*ve with both hands, holding its head down, pushes it down and holds it down with Her long legs while sitting on the edge of the hot tub. By the end, the sl*ve is a broken, blubbering, stuttering mess, thanking Her for its punishment and begging for more subjugation to Her.
