2B or not 2B

2B and 9S were on a mission when a strange object caused them to switch bodies. 9S wanted to try and fix the situation, but the excitement of the female body led him to masturbate, and when his sister awoke, he began to masturbate her, letting her revel in the wonder of male sexuality.

After having sex, 2B and 9S decided to stay in their new bodies. They no longer wanted to return to their former selves; instead, they were going to enjoy the excitement of their new bodies, and nothing, not even Commando White or the Bunker warriors, would stop them.
