Natasha would never have done it had she thought it would really freak Clint out, but if they were going to play around in the water then he should really expect to get ducked under at some point. This was was just a little more surprising and, hopefully, a little more pleasurable.

He certainly responded quick enough.

He returned the kiss more than a little enthusiastically, and his hand was almost instantly under her top, kneading and caressing her soft skin. She could feel him pressing against her ass and ground back against him, her tongue battling his until her lungs started to ache. Only then did she pull his hand out from under her top and release his legs. Keeping her grip on his wrist she grinned at him before rocketing to the surface, though once they broke through she swam away out of arms reach and watched him with a mischievous expression as she adjusted her top to fully cover her again.
