Interesting. For a moment I thought it would reverse both of them, turning Noah into Naomi and Tanji into a human. Either that or with what they were doing I thought Noah would turn into Naomi and fall inside Tanji's womanhood. Still it is good. Though i do hope Naomi returns to her normal mouse form simply because it has a bigger chance of her being swallowed. Maybe with a reversal where Tanjo gets turned into a Mouse girl as well and they both get swallowed by someone hopefully unaware. Looking forward to the next chapter.
