Serina enjoys her victim. He is caught in the smother box and Serina has total control about him and about his breathing. She is pressing down again and again, taking away his air. Will he be able to bear it as long as Serina wants him to? At the end there is, in any case, some special air for him to take in. She is pulling off her boots, then takes away his air again, and then, when he finally has to breathe again, she is putting the boot against his nose. Eager to breathe he now has to smell the smell of her boot, has to literally inhale it!
