at the beginning you can see how the vaginal muscles twitch when I touch the exposed clitoris with my tongue, it's interesting, the next attempt is to suck the clitoris with different tubes to achieve its displacement from the vulva and increase its sensitivity and swelling, then it's time to pump the whole woman external genitalia, where the labia and the entire vulva visibly swell and the woman masturbates to orgasm, and eventually orgasms me too
Love it all pumped up and wet.
