'Extreme! Orgasm Training!' is a sort of VN where a mad scientist kidnaps a girl and trains her to become humanity's savior. I say "sort of a VN" as you can go straight to free play after you complete the story; its a fap material onwards. The game is soft censored, as no genitalia are ever revealed to begin with. There are 6 senarios and two endings unlocked by reaching high numbers of orgasms.
The gameplay in free play involves you using different strengths of stimulant to enact forced orgasm, this only affects how quickly the orgasm meter fills up. The main strength of 'Extreme! Orgasm Training!' comes from the psudo-dynamic orgasm reactions and the VA. The bar and the voice acting changes at 4 different points; the heroine becomes more orgasm exhausted. After you hit max minimum horny level the game allows you to start over from 0%. I really want to rate this 4 stars because of the VA orgasm progression, but the gameplay isn't there with only 6 scenarios and no unlocks. Even without that though, I find myself returning to this game more often than I thought I would.
If you're looking for a high quality fap material, I'd give this a go.
