Oh, man, this stuff is easy! Trust me, there is absolutely no need to lie when you're gaming a girl, EVER. I'm 20, too, and I game older women all the time.
Controlling for the age disparity issue is all a matter of frame control. Here's a little quote from one of my FRs a long time ago:

I tell them I'm 18. They freak out and won't even tell me how old they are. All I know is that they're between the ages of 20-something and 30. I treat it like it's no big deal, treating the girls like they're weird for making any sort of issue about it. They're throwing shit-tests at me like crazy now, telling me that I'm just a baby and that I look like I'm in high school or some shit like that. I brush off the tests like dust and reframe the entire situation. "Alright, listen. I know you two wish you were young again, so I've got a little present for you. Just for tonight, you two are going to be 18 all over again!" (said with kino of course) At first they responded like old people, "Ohhhh my god it's been so long since I was that age," but with a persistent positive frame I eventually got them excited about the idea. Hey, I already had them hooked before we even got on the dance floor. This was easy peasy at this phase of the game. I even did some takeaways and opened other sets to preserve my value. Attraction was building. Whenever they would try to frame my young age as a bad thing, I'd reframe by negging them for being old, following it up with something like, "but how does it feel to be young again tonight? Woohooo!" This strengthened the frame that young = good.
That was a 2-set of older women in a club in Korea, a country where your age alone determines where you stand on the social hierarchy. I kiss-closed both of them that night!
As long as you are 100% confident that she is already into you, you can pass any shit test she throws at you easily.
