I recently had an experience that I gave handjob to a provider towards the later part of a session.  I certainly enjoyed it.  

I don't understand what you mean by vaginal jerking off. As far as I can tell, no part of my vagina could be jerked off in a way that would feel pleasant for me lol. Did she have a very long/large clitoris? Or did you just finger her aggressively/vigorously?

Rarely need there fingers.

I like for my clit to be manually stimulated...
But hey, sorry to correct you, but please don't call it a "handjob" or "jerking off" ok. That is very manly. Lol. My kooch is girlie.

Yea I just about require a gentleman to not leave me hanging n get me off.  Lol As for the scenario you speak of,  yes I do like the feeling of being "jacked off" as you call it I do have a gentleman that does this to me n it drives me wild.
btw that video was pretty fucking hot!  
Hugs and kisses

beating her plant.

I really get off on getting a lady off with my hands. While I am pretty good w/ my tongue, when getting her off with my hands I get to watch the expression on her face and see her body writhe, which I enjoy very much.  My ATF really enjoys my handiwork and am able to get her off 2-3 times that way before inserting my cock. Since my current meds have turned me into a once and done kinda guy, this helps extend both our pleasure.  

It's a surefire way to make me a VERY happy girl!  Not a squirter, but definitely a gusher.

I see one lady that has a very defined G spot and she goes wild when I massage it. Another lady claims it doesn't exist. Who knows as long as it's fun enjoy it.

They're not so keen on force until fully aroused...

squirt is just pee! What ever happened to that guy?

Very true. Personally....not much for hand stimulation as it is too rough (no matter how gentle one is), but tongue stimulation does it about 98% of the time, lol. The OP should ask the next if this is her preference, and then proceed from there, as everyone is different, and every lady likes different techniques. Unfortunately, there is no, "one size fits all", when dealing with women, lol.
