I'm glad you got the image from your head to the screen. It's well-drawn, innocently demure yet inadvertently provocative, what with her exposed hip and cutie mark. Mmmm. (That stands for Mesmerizing, Maternal Mare Madness.)
Odd coincidence that you should choose a light blue T. My pet image of late, like yours, has been of 'Shy emerging into her bedroom, lit from behind for a halo effect, looking hesitantly sexy, in a robin-egg blue outfit of silken flimsies...big mane and tail bows, tiny tie-on bra and panties, stockings (naturally), and a long, transparent camisole or gown on top.
I blame my image on the lingerie shop in the local mall, which have photos and mannequins in full view wearing this stuff...
To be honest, There isn't much of what to be grossed out of. Really. Most of the content you'll see there is either human or half human. It's basically like watching any other R34. Or hentai, For that matter.
I don't wanna speak like a perv, since I don't like thinking that way, but for some reason, when the mares only wear shirts or clothes for their upper bodies, it only draws more attention to their bare lower bodies. It makes me wonder why ponies rarely wear anything like pants, shorts, skirts, etc. Is it just mildly taboo to cover your cutie mark?
