Husband on Trip, I Called by Adult Store

After my husband left for his business trip, I got a call:

"Hello, I'm a clerk from a sex toy store. May I speak with Mrs. Miller? Your husband's payment for the sex toy he bought yesterday afternoon failed. Could you please complete the payment?"

I immediately called Alex, my husband, probing:

"Weren't you on a business trip yesterday? Why were you buying a sex toy yesterday afternoon?"

He paused for a second, then chuckled lightly:

"Oh, I was going to surprise you, but I guess you found out early."
