I like Eroge/Nukige with rape too, so I usually play all of new Bishop Games (haven't gone to all of old ones yet).
Have you ever played Custom Raid 5 (
http://www.getchu.com/soft.phtml?id=716461)?
You play as a chairman of a school. Your job is to kidnap female students and teachers (you can customize their appearances and names), train them, and make money by multiple methods (ex. clear quest, sell girls, etc).
This game is kind of like 館～官能奇譚～(
http://bishop.jp/products/ykt/index.html) by Bishop + customization + much more girls (that you can create).
Lots of games by ルネ(

Have you tried 鉄と裸(

You are a powerful, immortal magician who's been sealed by other humans because of your craziness.
Time has gone by, no one believes you were real - you are just a myth. Your seal's finally broken by oblivious thieves and now it's your turn to get back your powers and take revenge on descendants of foolish humans.
The art style may not look too good, but it got solid contents and rapes.
How about プレイ！プレイ！プレイ！GO！(

I haven't played it, so I don't know if it's good or not, but its description mentions that the protagonist is going to rape fuck ton of girls.
