Nat was biting her hand, trying to keep herself from laughing as her boyfriend loomed over her, using his weight to pin her to the bed.
"You're one tough cookie, aren't you, Doll?" Bucky chuckled, pulling up her pajama top, smirking when an unintentional whine escaped her.
He smiled, studying her bare stomach like a map, making Natasha shake her head no.
"I think you're long overdue for a test of your tickle button."
"I think we can skip that." She said, squirming as giggles bubbled up in her throat. Bucky ignored her protest, leaning down to press soft kisses to her stomach.
"How do kisses feel?" He asked as the giggles started to pour out of her.
"Fine, we can stop now!" Her voice jumped an octave as he began to nibble on her tummy.
"Oh no, but we've just started. Let's see, kisses, check... nibbles... check." A sudden raspberry made Natasha squeal.
"Raspberries are still effective..." Bucky sat up and fluttered his fingers over her bellybutton, Natasha couldn't fight the laughter that poured out of her.
"Aw, you're so cute when your tummy is being tickled." Bucky cooed, a fingertip swirling around the rim of her bellybutton.
"No!" Natasha’s face was red, though from exertion or embarrassment was anyone's guess.
"No? I think you are. In fact, I can prove it." He blew another raspberry directly over her bellybutton as he scribbled his nails across her stomach.
Nat's hips bucked, but Bucky's weight didn't shift an inch.
She was stuck.
"Coochie, coochie, coo!" The teasing made the tickling so much worse, and Natasha burst into helpless laughter.
"No, no, no, teasing isn't fair!" Another raspberry made her shriek.
"I think your tickle button passes inspection." He nibbled her belly again, making ridiculous noming noises that drove her crazy.
"If it works, then stop!" She managed between giggles.
"I could..." The tickling stopped for a moment, Natasha’s stomach hurt from laughing as she tried to catch her breath.
"... But I'm having too much fun!" Nat screamed as he blew several raspberries all over her belly.
