For context: In the videogame adaptation of the 1st Spiderman movie, you can play can as Mary Jane by entering the cheat code "GIRLNEXTDOOR". This leads to one funny moment later in the game which the programmers forgot or didn't care. If you play the game normally, Spiderman/Peter Parker rescues Mary Jane and later kisses her. But if you play as MJ, she rescues the Mary Jane the npc and kisses her other self, a lesbian selfcest kissing scene.
