Help Me, Teacher
Uke is a math teacher who discovers he's an omega. He goes into heat at school and has a threesome with 2 alpha teacher semes.
Shou Sensei no Ecchi na Himitsu
Eh kinda forceful at first seme is straight kind of a dick at first and rapes uke who is a preschool teacher. 2nd story though is *chefs kiss*.
Motoyan Papa to Hitsuji-sensei
Pretty cute. Two friends from high school meet again. Seme is now a single dad and his wife died while uke is a elementary school teacher. Really cute and fluffy.
Boku no Omega yo Samenaide
Slightly rapy at the start. I like the main couple though they're cute alpha seme and omega uke. The school who employs the omega are dicks though.
Sensei Datteyarashii Koto Shitai
Pretty cute. Teacher x teacher. Seme is a serious cute virgin and the uke is past delinquent teacher who messed around a lot before. It's cute.
Your distance
Pretty cute story and interesting. Seme and uke meet on a dating app thinking they live thousands of kilometers away but one day they are only a few uke then discovers the person was his strict uni professor. Age gap.
