My uterus ejaculated as I squeal

This beautiful girl reacts abnormally deep inside her vagina, around the cervix. She repeatedly thrusts towards it, and then suddenly ends with an incredible ejaculation at the cervix, which was so close that it lost focusing that it couldn't help but open her eyes. At that time, she had an expression on her face that should not be shown to others, and she was no longer the Tsubomi-chan you all know.
