"You say you want it to be a surprise," Aurora pointed out, tossing her hair. "So I go, so I am surprised when I come back, yes?" And she landed lightly in the back of the truck and looked around curiously, bouncing a little to test the cushions under her feet. Which she couldn't feel, because of her heels, so she took them off and tossed them over her shoulder, one landing on the cab of the truck, the other in the field nearby. There! That was much nicer.
And it was nice. She appreciated the thought that went into the setting. Making love in the back of a truck without any cushions seemed very uncomfortable and may have been a dealbreaker, but this worked. "I like this," Aurora told him, taking the cushion and plunking it down next to him. Then she ignored it to settle on his lap, straddling him with a thigh on either side.
"You are a very prepared person, I think, mon joli," she said, leaning in to brush his lips with hers. "And I think dinner is for later."
