I'm a nurse or doctor, come into my office where I have some medical gear laid out. Black rubber gloves, lube, an anal dilator and an oxygen mask. I stroll around the front of the desk, stretching the gloves over my hands, then lean against the while I stretch the strap of the mask over my head, and place the rubber mouthpiece over my airways. The mask gently inflates and deflates as I touch myself. I turn around, lifting my skirt to show stockings and garters, no panties. I look back at you, allowing glimpses of the mask and its rise and fall. I open my ass with latex-clad fingers, lubed up. Deeper and deeper, pressed into the cleft of my ass, stretching it more and more. I begin with the dilators, smallest first. I moan into the mask, enjoying the sensations, which start off mild, then become more and more intense as my ass is stretched by larger dilators. I lift one leg up on the desk so I can probe more deeply. I can't help myself and I get right on top of my office desk, grabbing a large acrylic probe and shoving it in my warmed-up asshole. I fuck myself hard and fast, deeply in and out, moaning more and more into the mask as I cum while fucking my butthole hard.
