I got the feeling her body was stiff. Like when she spread her legs wide or hugged them and opened them up...
I think this model is still appealing because we can see her masturbating.
Her bud and expression after she climaxes are so beautiful it sends shivers down my spine.
When I took all her clothes off, I found that Kurumi had a surprisingly feminine and attractive body, more so than I had expected when she was clothed. Her crotch area was quite lewd, with her labia minora and clitoral protrusions exposed, perhaps because she had little subcutaneous fat.
