Hello again! I'm wondering if you can illustrate these two girls:
Chisame Hasegawa (長谷川千雨) from Negima https://negima.fandom.com/wiki/Chisame_Hasegawa#Gallery

and Miyako Inoue (井ノ上京) from Digimon Adventure 02

Both are also wearing only high-cut fundoshi (ふんどしのスーパーハイッチ前系)
Chisame is wearing bright red

Both of them are lying together on a bunch of blankets and pillows, sweating on a hot summer day
