It's tagged on pixiv as 恐竜の玉子 (an ice cream - top left) http://www.marunaga.com/7seihin/n_fancy/fancy.html but it seems simpler to tag it as what it looks like.

Not the first time that sort of ice cream has shown up here on the 'booru, though I can't recall how it ended up being handled. sexually suggestive + ice cream seems like an easy fix?
