Typical Hentai Lines

[font=Courier New]That is a big turn on for me. I know, I'm a sick fucker. [/font]

Then we are both sick fuckers.

Luckly I can't understand that word fast enough and don't take it as bother or sister, just a name, not into incest...

One of my new favorites "Come take care of this "Global Warming" inside my pussy."
"oh yess, yess.... NOOOO!"
"Oh your so big, you're cock is just filling me up."

lol, most used. "it tickles!"

The whole Onee/Onii-chan/san thing is also a big turn on for me, but only if the siblings are around the same age. Something about how tabuu it is really arouses me.

"Cum inside me!" Has also always been one of my favorites.

My cock is melting!

"It doesn't hurt even and feels amazing even though I'm a virgin and that makes no fucking sense at all!"

One I've seen a lot is "You're being too rough!"

"it feels so good"
"harder harder"
"it's hard already"
"please cum inside"

"ah!" lol thats the most basic and generic one ever
"more"
"harder"
"i love your ____" insert whatever fills the blank: dick, cock, pussy, etc.
"it wont fit" though it always seems to
