So, just because I think cunbusting knowledge is valuable - if you like pussy pain, I recommend you go look at the art of I-Rabi.

I-Rabi has a super high quality translated series called Otomaiden.
It specializes in Ryona and hits to the groin. Nothing guro or anything, but if you just like watching super cute girls getting hit in the crotch, I-Rabi is some great quality work in that area.

You can look at and purchase his translated work here:
