TD036DV-01689 - Screaming climax by Nanami Kawakami, non-stop hardcore action

The position where she's awkwardly leaning against the headboard on her elbows looked so painful, especially seeing how her neck was bent and how much tension was in her arms. Her stomach looked flabby and folded, too. Even in the cowgirl position, she was bracing her legs, so she should've been able to move her hips, but they just kept thrusting from below without any hip movement. I thought it was going to be another neck-straining missionary position at the end, but thankfully it went back to normal. Then she wrapped her arms around his neck, so I thought it was a standing position, but then she let go and went back to missionary. What were they trying to do? I don't know if the actor was bad or the director's instructions were poor, but another camera was visible in the shot, so the director must have been terrible.
