trap tag? why? I see boobies on both of them

It's tagged as [男の娘] (essentially boy-girl) on Pixiv, the JPN tag for "trap". It's also tagged with [ゆり?] ("yuri?"). Yes, that includes the "?" as part of the tag. By artist definition, one of these is a male (or a futa maybe, but futa wasn't tagged.)

Also, men can have boobs too (manboobs!). Though that's more western in connotation. Just keep in mind one of them has boobs under clothes (the blonde), so that doesn't necessarily mean the boobs are real. (Anime girls are known to pad their chest. Traps might do the same ^_~)

ya, they both have sizeable breasts. and theres no sign of it being a trap or a futa. i would say remove that tag but im not sure if its the right move.

on another note, very nice picture. really like the art style and the way the faces are drawn

I believe that it is from manga "My Doll House" [ http://www.mangaupdates.com/series.html?id=37796 ]
and the one with brown hair is a guy (the breast are just realistic add-ons)

yeah, "blonde" is definitely a guy...
I can see it in his face.
