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 she reaches an orgasm that will make her slender, long limbs sway around, and ends with an incredible ejaculation in the cervix, which has opened up. At that time, she had an expression on her face that should not be shown to others, and she was no longer the Ai-chan you all knew.
