This is not Ahegao. This is a vacant expression, at least the two at top are. The one at bottom is, or seems to be enjoying herself. When you think Ahegao, think LUSTFUL gaze or drowning in pleasure. The dudes face is simply sinister. Nope, no ahegao here.
Much better than most Anime where breasts are the only way you can tell a guy from a girl. Wussy pretty boys are not sexy, unless you are the kind of "guy" that enjoys Twilight.
