You get a condom

You decide Carmen's ripe enough for the taking, and move away from her breasts
to reach into the front seat's glove compartment to fish out a condom.

"Wait ... wait," whispers Carmen, out of breath. "What are you doing?" She looks
over and notices you reaching for a condom.

Carmen quickly covers up and closes her legs. "I'm ... I'm sorry. I don't think
I'm ready for that yet." Carmen starts, as she begins to put her blouse back on.

After finishing getting her clothes on, she looks at you and whispers, "I probably
should have told you ... but I'm waiting for marriage before having sex."

...

The mood having been killed, the rest of the night disintegrates into a long
talk about how Carmen wants to stay a virgin and why she does. As such,
you do not get into her panties. At least, not tonight.
