So, I think the script that was submitted for this One-Shot can better describe it than I can. The premise was described thusly:
A sex tournament begins, where various fighters compete in sex in an attempt to be the champion. Confident of Gohan’s abilities, Goku signed him up to represent the Z fighters, and said he was confident that Gohan could win, even if he were to have to fight multiple opponents each round. A challenge that the other fighters quickly took him up on to gain an advantage.
The health/pleasure bar gimmick was also described in the script, including the percentages for each panel, but the shape of the bar was my own personal touch. The setting was also left open, other than being some sort of combat arena. I thought it’d be fun to reference the Ultimate Submission arena used by kink.com, but I used some more vibrant colors that I felt better suited what you might see in a game like Street Fighter.
I don’t expect everyone to recognize every character Gohan’s going up against here, so I’ll try and help. Panel one has Master Raven from Tekken and Ivy from Soul Calibur. Panel two has Sonya Blade and Mileena, specifically their Mortal Kombat 9 designs. Panel three has two characters not traditionally thought of as fighting game characters, Samus Aran and Princess Zelda, representing the Super Smash Bros. series. Panel four has Orchid from Killer Instinct and Elena from Street Fighter. Panel five has Chun-Li, Cammy White and Laura Matsuda, all of whom are also from Street Fighter.
