So this scene will be split in three different s. I'm going to describe each and how I want things to play out.
The first it will go like this. Ibuki has her legs apart as Guy goes at it missionary style in the bath tub. Her facial expression should match the first picture and as for Guy give him a serious facial look while showing his teeth grit a little as he is pounding her. Both of them should be covered in bath water as they are doing it.
The second shows Ibuki being done from behind as she lays down being pounded away while Guy goes at it. Guy's face should look like the fifth picture I attached. As for Ibuki, her face should be exactly like the fourth picture. Also, give Ibuki a nice round behind, exactly how it's shown from the fourth picture.
The third and last will end with Guy blowing his load all over Ibuki's face, chest, and stomach as it is shown in the last image. Her expression should be that of exhaustion and fatigue as her time with Guy was very intense. Try and match exactly what is shown in the last image.
