Very possible. Avg distance is about 8 inches so the entire vibe's inside it can easily hit the cervix. Some women like it, some don't.
Wetter experience or orgasm though wouldn't be due to hitting your cervix but stimulating the g-spot. Contrary to some writers on this subject, I tend to believe the chemical analysis reports on female ejaculate fluids saying there are two sorts, one a diluted pee, the other a prostatic fluid (urethra and vaginal secretions respectively.)
To demonstrate that the "real" female ejaculation and the "squirting or gushing" are two different phenomena.
Biochemical studies on female fluids expelled during orgasm.
In this case report, we provided new biochemical evidences demonstrating that the clear and abundant fluid that is ejected in gushes (squirting) is different from the real female ejaculation. While the first has the features of diluted urines (density: 1,001.67 ± 2.89; urea: 417.0 ± 42.88 mg/dL; creatinine: 21.37 ± 4.16 mg/dL; uric acid: 10.37 ± 1.48 mg/dL), the second is biochemically comparable to some components of male semen (prostate-specific antigen: 3.99 ± 0.60 × 103 ng/mL).
Female ejaculation and squirting/gushing are two different phenomena. The organs and the mechanisms that produce them are bona fide different. The real female ejaculation is the release of a very scanty, thick, and whitish fluid from the female prostate, while the squirting is the expulsion of a diluted fluid from the urinary bladder.
