If you're looking for manga similar to Comyushou VS Yuri, you might like these titles.
Hanami Harumaki is a high school P.E. teacher with daily morning entrance duty at the school's gate. Tomboyish and awkward, she meets a new student, Urara Momojima, who surprisingly, has natural and striking pink hair (pink haired girls have a reputation for lewdness in dating sim games). Momojima immediately takes a liking to Ms. Harumaki, and makes her best to seduce her, but they're both not particularly "smart" girls.
The practice of "giving financial support in a relationship" is common in Japan among older men and younger women... but between two girls in high school!? Witness the silly shenanigans of Sachiko as she finds all manner of ways to milk as much money out of her girlfriend, Miho, as possible!
