KKCM-024 - Charismatic Gal Rika's Teasing Hell Vol. 4

I personally liked this girl, so that was a plus. Her tan skin is also fantastic. As for the rest, just like the title says, the male actor is fast. There is penetration (while wearing underwear), but it's over in about 3 minutes. However, looking at the off-shots, I wondered if she might actually be an M in real life? During the performance, she stays in character, so she might look like a genuine S at first glance, but depending on how you look at it, it feels a bit superficial or forced... I'd like to hear everyone else's opinion on which one it is.
