Really good Mai x Andy Genderswap Yuri doujin by Apollo. Taken directly from their Pixiv:

Be sure to check out their stuff there if you like this; they've made tons more KOF and Genderswap pics.

The plot is based on SNK Heroines Tag Team Frenzy, but UHM ACKSHUALLY if you aren't a FAKE FAN you'll know that it's also based on Mai's ending in SNK Gals' Fighters for the Neo Geo Pocket Color.
Andy and Mai are written really well in character here, so if you're picky about that don't feel the need to skip this one.
The doujin is from Futaket but contains absolutely no futanari content whatsoever. My condolences/congratulations.
