Birthday Present

Diane's husband spent most of his time on Mars, and I spent most of mine with Diane. It was a nice arrangement—much too nice to last!
It's tonight or never, Diane said.
Yes, I said.
I watched her as she walked back and forth across my bedroom floor. She had on a sheer plasto dress that clung to her round white breasts and full milky thighs. I'm picking him up at the spaceway, she said. We're supposed to go dining and dancing tonight. She stopped pacing. It's my birthday. I'm thirty today.
And I was twenty-four and in love. Six years between us. So what? I didn't give a damn. I wanted to marry her, to live with her.
I'm thirty, she said again. Do you mind?
I know your age. Why bring it up?
Someday you'll find out you married an old woman. If we ever do marry.
Stop it. I got off the bed, went to her. Just tell me what to do and I'll do it.
Do you love me? she looked up at me.
You know I do.
Say it.
