I really want to like this, but there's just some major flaws right now.
The sex fight ideas are delightful, and that art is wonderful. The action cut-ins are in a different style, which is weird, but I figure they're temporary.
But there's only the four poses for sex fights, and it's just not fun to watch the exact same art over and over. Sex fights seem to range from 4 to 8 opponents under normal circumstances, so there's no sense of progression: you start in a gangbang, you promote to a more-tedious gangbang, and stamina costs are so huge that you have to continuously chug stamina potions. Near the end of current content, opponents get sadism attacks and that just makes the balance even worse.
The sex skills are not balanced at all. If you start with the Blowjob skill, you have enough skill points to learn the Handjob skill, which doubles your lust damage output per turn. For any other starting skill, you can't. (Then again: it takes so many turns to make each opponent cum that this additional lust damage barely matters.)
The plot's ok: well-meaning protagonist gets involved in something she shouldn't, gets sent into a ridiculous situation, discovers a magic Tome on how to rule men through lust. Formulaic, but reasonable.
But at the end of the current, a narrator pops on screen for just one sentence, to let the audience know that something is supernaturally corrupting the protagonist. Why?? The situation is already deliciously full of situations to ensluttify the protagonist and the book is already magical. To have the narrator suddenly show up is horribly incongruous, and as a plot idea it ruins the impact of the rest of the story. There's suddenly no temptation, no desperate situation, no compromise. A wizard did it, how boring.
