Warnings, if any, implied nudity and sexy-time, yaoi, I guess that's it.
Britain plunged his hands into the tub, grinning at the warm water that splashed up his chest. His boyfriend wrapped his arms around the other country's stomach. Britain gasped as he felt America lean in and kiss the shell of his ear, smirking. He leaned back into the taller blonde's chest. He put one arm around America's neck and turned his head, letting himself be swept into a kiss.
America cupped Britain's cheek in one hand and put the other hand between his legs, making Britain gasp a bit and press harder against his chest. Smiling, America broke the kiss and used one hand to pull Britain's leg up toward his chest, still stroking his cock with one hand. Britain moaned and bit his lip.
"I'm glad you convinced me to take a bath with you," America whispered into his boyfriend's ear. "And these bubbles smell so sweet…" He scooped a handful of the cherry-pomegranate scented bubbles into one hand. "…just like you."
Pulling his hands back from a quivering Britain's body, he picked up two handfuls of the bubbles and put them on the blonde's wet hair, laughing.
As Britain squeaked indignantly, America pulled him close and kissed his cheek softly, tenderly.
"After this," he said sexily, "I think I'm going to take you."
"Wh-What?" Britain turned a fascinating shade of crimson.
"You heard me," America teased, slipping one hand under his thigh and teasing his cock lightly with his fingertips. "I'm going to take you after this. This bath is turning me on, and it seems to be doing that for you too."
Britain went darker. He twitched and hardened under America's gentle caresses.
"Th-That's you, you git," he tried to retort, but America turned his head again and kissed him, deeper this time. Britain managed to ignore the bubbles on his head and focus on the fingers on his sweet spot. He managed to ignore America's bare chest against his back and focus on kissing him.
He was glad America had taken a bath with him, too.
