"Bikini Day"
"Well, this is something new," Phil said, determined to believe the absolutely best about his partner, and not suspect him of infidelity, or buying inappropriate gifts for women, and these were definitely too big for Pepper, Natasha, or Jane.
"What?" Bucky said, poking his head into the bedroom. His eyes widened when he saw the bra and panties dangling from Phil's index fingers, and he turned bright red. "Ah. Those are mine. I bought `em last week, but I got cold feet, and I was gonna return `em today…"
"Mmm. No need for that." Phil's lips twisted up at the edges. "I look forward to seeing you in them."
Not a three-sentence fic, but a three-paragraph fic. Eh. Liked it? The thought of Bucky in lingerie… Yummy.
