the woman's acting is also quite realistic, especially all the head shaking before kissing and fucking.
i have no idea why they actually do that but that is exactly what the japanese woman did that i picked up in a hostel in poland recently. i managed to make her get a hotel room with me and when we arrived i directly made a first attempt to bang her at bright daylight, completely sober. she did that head shaking a lot and seemed hesitant, pulling back and sitting there. after several times i got tired of it and suggested to stop and go to the city. but then she said "no, i want you". it didn't seem like she's playing game though, it really felt like she couldn't help but act like that. i wonder where they learn that head shaking refusal shit. or is that some built-in japanese hardware?
