You Don't Do Mixed Bathing? is part B of episode 57.

Summary
Koma gets an idea from Oga's Super Milk Time training to switch bodies with Aoi Kunieda by offering her Manju. He has some fun moments with Aoi that gets pervy but he also spends a good bit of time with the kids, of which Koma fits in pretty well. His attempts to push them into his own designs are definitely fun since he wants to utilize the body switching ability for his own ends, which is essentially to get into Aoi’s body and play with her end.
