He watched out through the diaper as she went to leave the bathroom, however, she first decided to see how she looks. Her diaper was poking out slightly, but not enough to identify what it was; Satisfied with that, she went out.
Her legs rubbed against Jeff as she walked, helping her puffy vagina as a cushion. The more she walked, the more Jeff decided he could get used to this.
As Diana got in bed, Jeff had a thought. "This is going to be weird, but I'm curious..." He reaches into her urethra, poking the sides with his fingers while using his feet to stimulate inside of her vagina.
Due to the stimulation inside, she started to squirm a bit, moving around and trying to get comfortable. He could feel a slight vibration within her vagina, and waited for it to come out.
Her urethra twitched, as Jeff opened his mouth. A giant stream of golden pee came out, and fast. He got a mouth full of it, and sat there, trying to decide on the taste.
He took a moment to decide, as Diana drifted to sleep.
