Deep throat until you cum and then piss in the back of your throat (Part 1/2)

We wanted to do something new, so we did a different position, I was on the couch with my legs up and she sucked on top with all the ease in the world taking all my cock in her mouth. This position is not comfortable for the balls, I decided to tie them with the elastic band. The setting was perfect, she managed to have fun completely and suck all my white and yellow liquids more easily. There's a moment, at the end, when she can't drink all the urine, she runs to the bathroom, but then comes back as an obedient little slut to finish drinking all of her male's yellow juice.
