Hallo hallo haloo i need older seme and then young uke pls like badly

Koi ga Ochitara followed by Koi ga Michitara
It's a really great one!!

If I recall any other great titles I'll swing by again (๑•ㅂ•)و✧

A mixed bag of older seme, younger uke. Some don't have that big of an age gap but since you didn't specify, I placed what I could find here. Some might be...meh like unholy night coz of incest vibes but there ya go.
