BLK-253 Gal's weak point, entrance to the womb Ria Arimura

A hot-blooded, reckless, and arrogant older sister. I want to see this stuck-up gal's pathetic face no matter what. My target was the entrance to her womb, which clearly changed color every time my glans touched it. Even though Yumura-san had been so composed, when she desperately said 'Just don't dig there any more,' I dug and dug at that spot until she couldn't take it anymore and her jaw jerked up, at which point I shot my semen into her.
