Belly Punched

Shinju is recruited by two shadowy Special Agents, one male, the other female, to help take down a human trafficking ring. Just a simple undercover operation. There was only one problem: the tall blonde woman operating the ring would test her first. Or more accurately, Kyndall would test Shinju's abdominal muscles to see how many punches they could absorb. The second test would involve sushi being eaten off Shinju's body.
The agents showed her a video of another woman undergoing the test. First were strips of salmon, one on top of each breast, then down her belly. And then Kyndall took her time dropping dollops of Wasabi sauce, one beside each strip of salmon. This isn't too bad, thought Shinju. But when Kyndall smiled and picked up an octopus, Shinju gasped. Her eyes bugged out when the blonde hellion dangled its tentacles over her victim's-What with all these tests, Shinju had difficulty reporting in, and who wouldn't? So the agents showed up unexpectedly at a Jello wrestling competition.
To maintain her cover, Shinju wrestled the female agent. Bikinis became pasted to bodies. Bikinis ripped. Right after 'dessert', Shinju went back undercover and under the covers to complete her mission.
