[JUR-846] Stepmom, you want a K*d, right?” while my indifferent husband was away on assignment, i kept getting bred and creampied nonstop by my horny stepson yuichi…

I believe she has always put on the loli voice because she doesn’t want to share her natural voice (which is deeper and much more adult, you see it in glimmers here and there). Some model’s like to hold something of themselves back, maybe it gives them a sense of self-preservation. For example, Satomi Suzuki never allowed any guy to come on her face for her entire career. And huge numbers of models don’t allow cream-pies (even though those are faked as we know).
I put aside Minami’s voice when I watch her , it’s only an aspect of what she does. She’s a gorgeous woman, and her body is HER. She fucks VERY well. She’s a good actress too.
