what monogatari is this?

If you mean the monogatari series, then this isn't from it.

That isn't from the Monogatari series, searching it turns up lots of porn sites so I'm guessing it's cropped hentai.

OP here. I guess I'm still curious.. I'm intrigued by the art. I really like the eyelashes and the expression and the saliva.

It reminds me of senjougahara and that nisemonogatari toothbrush scene simultaneously.

That's how the chinese draw their chinese animes. Just look at anything chinese or outsourced to china or based on a chink LN.

The OP image is specifically from Allargando. If you're looking for more (hentai) similar to the style, look up the artist Seto Yuuki.
