While it isn't exactly a marathon, I do cum hard three times in 10 minutes in this video. I show you the facemasks that I have, since most of the world is wearing these, I thought you may be getting horny if you have a mask fetish, thinking of what women may look like under them, or what it may be like if they got breathing heavy and excited in a store bathroom for a quick masked encounter. I use my new clit sucking vibrator and the view remains closeup the whole time, in "beautiful agony" style, you get to see the expression in my eyes, hear my muffled moans and groans as I cum in each of my masks for you. The last one is huge!
