I just know that I find Ptera hot. She's pretty visually striking compared to the other girls considering she's the flattest adult shown so far in the comic.
I'm more curious about the putting goggles on your thigh. lol
I mean, the eye-test shirt comic had eyeglasses hanging off the girl's thigh, so I think that's just a thing this author does. At least these ones actually look like they'll stay on!
