I'm a doctor alone in the hospital, and I'm feeling horny. I have my mask on still, when I go over to a table and put on a pair of rubber gloves. I start caressing my tits, enjoying the feeling of the rubber on my nipples and breasts. I moan into the mask, which heats up underneath. I sit down on a chair and start to play with my pussy. But I want to feel more intense sensations, so I remove the mask and put on an oxygen mask. I caress and adjust it with my gloved hands, then proceed to finger myself more intensely. My breath fogs up the mask and the bag swells gently. The camera comes in close and you can see it rising and falling with my hastening breath. I get more wicked the hornier I get and soon I reach for a speculum, spreading my pussy wider and wider, enjoying the exposing and naughty sensations. I rub my clit which is exposed deliciously and cum hard while wearing my oxygen mask. Then, slightly embarrassed of my doings, I put myself back together and leave the room
