Nikko and Sosha make out and pee in their diapers in this video.
We find Nikko and Sosha on the bed, wearing only thick, tabbed, adult diapers. They are passionately making out when they realize that they both need to pee.
Since they are both wearing diapers, they decide there is no reason to leave the bed. First Sosha wets her diaper, followed by Nikko. From the close up angle you can see the diaper fill up and change color as she pees in it.
After they have both peed in their diapers, Sosha and Nikko resume making out for a bit and rub each other. Tired, they lay down on the bed and snuggle together in their wet diapers.
