I really have a love-hate relationship with this. I love drooling over something as hot as
this, but I hate editing it. It's such a pain to find proper fonts for it.
This is my only guideline.
1) Always make the text of the person who's 'feeling good' or 'being molested' italic.
For words like nipple, gasp, pant, haa, squirm, shake, stroke, etc I'm using
For the words like tighten, grab, slide, thrust, release, spurt, aroused, twitch, etc. I'm using different fonts.
In the above given example you see that 'bold' was being used. If someone is getting 'entered,' that person
won't be able to keep his voice down. So here you can either choose to make the text bold or make it bigger.
