ideas (if ur not full of 'em)
Dominant/dominance: Makes her act way more dominant. the sex scene changes to you eating her out.
giant/giantess: giant gives you the "giant ending" (Literally just makes you giant) and giantess makes her HUGE! she just sits on the floor. horny Would also now Cause a game over Because in her hormonal state She would accidentally crush you ;.; .
Jarate/WANKER!: turns her into sniper tf2.
sus: she refuses to drink it, And if you try to drink it You apparently "miss your mouth" until you throw it out
neko/cat: makes her into a cat girl.
