If it's this one, then it's just Kondo San doing some cosplay ^^''

I think that it might be a work by sakira sensei
this one has a cover similar to what you described
http://www.mangago.me/read-manga/sailor_danshi/
and in this manga the seme eats whipped cream and strawberries of the uke ლ(´ڡ`ლ)

sorry if its not what you are looking for but its still good manga.
I don't have a lot of information, I only remember the cover and I've never read it before( ̄∇ ̄") I think it's a lemon yaoi
the cover is like some muscly guy in a magic girl outfit
and possibly with like some cream and strawberries on him. I hope that you guys can help me (๑•ㅂ•)و✧ Thank you so much <3 :3 uwu xD
