Pretty impressive, seems like you might have done this before. Personally i dont use water though, you just lift the other end up and all the marbles roll into the sheeps ass.
tease her unexposed clitoris with your tongue until it’s fully erect. Gently retract the hood until the clitoris is partially exposed, and dart your tongue across it. You’ll want to repeat this move gently and quickly, varying the direction each time and pausing between each flick of the tongue. When she starts begging for more attention, release the hood and increase the degree of applied pressure until she reaches orgasm -- which should be right around the corner.
