WANZ-258 Ejaculate my uterus and make it bud

This beautiful girl exhibits an abnormal reaction at the deepest part of her vagina, around her cervix. Aiming for that point, I repeated the piston repeatedly, and finished off the cervix, which had spread so wide due to the climax that my eyes couldn't focus, with a tremendous amount of ejaculation. At that moment, she made an expression that should not be shown to others, and she was no longer the Tsubomi-chan you know.
