Ruby's PVC Ass Crush

Domina Ruby has one slave blindfolded on the floor and another in the stocks.  Today she’s working them both over big time.  She starts by plunking herself down on the first slave’s chest, knocking the wind out of his lungs.  She bounces up and down, causing him to grunt and groan until she silences him beneath her PVC covered ass.  “Let’s see how long you can hold your breath” she tells him.  The slave does quite well at first, but eventually he’s past his breaking point.  When Ruby finally gets up, he frantically fights to catch a breath for an instant before she’s back down on him again.  As she sits on him, she makes things even more difficult by pulling on his nipples. 

Ruby is not in a generous mood today, and at the moment, she sees no reason to let her slave breathe.  You can see and hear how frantic he becomes before she eventually sits up, again, only for a second.  This time she sits for an even longer period of time before getting up to give her other slave a second of attention, making sure he’s watching, because he’s going to be next.  She returns to sit on the first slave’s face again, this time in the forward position.  She really tests his limits and when she gets up he’s almost frantic.  She tells him to relax but then sits right down again. The slave’s cock starts to grow as his limits are pushed, and this time Ruby gets a nice long sit from him.  She gives him a short breath before she sits down, and this time she just lets him kick and kick and kick, while you listen to his muffled screams coming from under her ass.
