Gal's weak point, uterus is in the uterus

A strong-tempered, forceful, and wary girl. I want to somehow see this beast gal's pathetic face. What I was aiming for was the uterus, which clearly changes color every time the glans gets caught. Such an aggressive "AIKA" desperately tried to tease him and tease him, only to the point where he said, "just don't blame him," and poured his sighs into the place where he yelled!
