Peeing with 2 vaginae

Suddenly, Sarah released her clenched bladder. Jon felt a rush of warm fluid racing along Sarah's urethral tube towards him. When it arrived, it started spraying out of his urethra, which felt like it was on the roof of his mouth. The yellow liquid gushed past his lips in a wide spray, arcing downward as it entered the toilet. He saw a second stream alongside his own, and realized that Karyn must be experiencing the same thing as himself. He hoped she was coping as well.
Jon was glad that he had no sense of taste, as he lacked a tongue, but it was still very strange as he could somehow smell the pee as it left his body. It smelled like a girl's pee, with a characteristically feminine scent. As it left him, he felt the pressure above him start to wane, as Sarah's oversized bladder drained.
For Sarah, this was also a very new experience. All of her life, she had peed using a single vagina; now that she had two, the two streams felt very strange. She supposed that, in time, this would become "normal" as she adjusted to having a pair of equally perfect genitals. In the mean time, she gazed downwards in fascination, noting with a chuckle that the two people who pissed her off the most were now "pissing" in a much more literal fashion.
Slowly, the streams waned as Sarah's bladder was finally empty. Sarah took two wads of toilet paper, one in each hand, and simultaneously wiped both Jon and Karyn dry. She didn't want her new genitalia getting infected, after all.
