Roads

This is from a play I am attempting to recreate from memory, a little 10-Minute ditty under the working title "Roads" (titling a play is often the hardest part for me). The premise (in a nutshell) is that Jack is called by his ex-girlfriend Jill (naming characters is also a tad difficult), who needs a favor. She and her girlfriend, Edna, need to get to *insert liberal, gay-marriage friendly state* to get married, and they don't have a car. Jack and Ed (his roommate) drive Jill and Edna to said mythical state only to find that the law does not cover non-residents (or some similar exclusion).
Humor ensues.

Here's a small selection of what I've rewritten:

Nighttime. Jack and Edna sit in the back of the car. Edna lights up. Jill and Ed are sitting on the hood/beside the car.

Jack
Can I bum one of those?

Edna hands over a cigarette, holds up the lighter and lights it for Jack.

Jack
Thanks.

They sit for a moment.

Edna
How the fuck did you stand being around her?

Jack
I dunno. [Edna scoffs] No, I really don't. I guess... It just felt like shit most of the time, but I can't really remember what made it worth it. Maybe all the shit made the really good times feel... amazing.

Edna
Yeah.

Jack
Plus the sex was good.

Edna
For awhile

Jack
Then it kinda

Edna
Tapers

Jack
And you're back to firing one off into a towel

Edna
just to feel good

Jack
but even that stops working

Enda
It's not like she cuts you off entirely. That'd be easier.

Jack
Yeah.

Edna
Naw. She fucks you around for awhile, then doesn't fuck you at all, then fucks you every once and again just to keep you interested.

Jack
And that fuck, it's mind-blowing. It's amazing. It's

Edna
Epiphany. [beat]

Jack touches her hand, stretches out his neck, and kisses her neck. It is a movement almost entirely without affection, just lust. They fuck. Jill cries.
