Onee/Crossdressing/Feminine Men in Hentai

[tsuii.]

I've recently found this treasure called "Skirt no Naka wa Kedamono Deshita" and it's made me want to try looking for something similar, so I was wondering if anyone has any recommendations of "Onee" Characters (Not like older sister but crossdressing men or just generally "beautifiul" or feminine types of guys. Please and thank you!
