Help finding 2 Adult Comics from like 12 years ago

[Arkaia]

I do not remember their names, but they are burned into my brain.

1. About a she-demon named Horny (queen/princess of Hell maybe?). Don't remember much about it. She leaves hell and hell tries to get her back. Has some action to it and is gory. The art is really good quality.

2. Guy convinces girl to try out his virtual reality machine that sends her to the stoneage where she gets assaulted by a tentacled-dinosaur, screws stoneage Tarzan, and gets gangbanged by cavemen.

Anyone know the names of these comics?
