What would you most like to do to/with a tgirl?

[tlover]

Imagine your with a beautiful working tgirl for the first time, unfortunately she is very expensive and you can only afford to do or have her do ONE thing to or with you, but she is so sexy and she has a big swollen bulge in her skirt for you and you cannot resist, you just have to have her.
So what would you go for?

Personally for me it would be hard to chooses between sucking her cock until she exploded in my mouth, or letting her fuck me senseless until she filled my ass with cream in the missionary position.
I think i would have to go for a fuck up the ass.

So how about you? You suck her, she suck you or fuck you? you fuck her? wank each other off? a 69 or something else?
