Tower of Dreams has the protagonist fighting her way through a tower, and fucking her defeated opponents. (She grew a dick for that - which as a bonus means she can even knock them up).
Roundscape Adorevia lets you play as a fantasy hero who even ends up killing an evil god. She can go quite deeply into "must worship massive cocks"-territory at times, but she's clearly powerful and fucks because she wants to.
Her Desire has a much more mundane setting. We play as a housewife who starts having sex with her best friend, both her friends and her own daughter, her son, and some other people. As the title promises, it's very much driven by the desires of the main character - and she's in control of the action.
Tales of Terraria has us back in fantasy land. The protagonist may start off getting captured by goblins, but she quickly enters a pact with a goddess and gains extraordinary powers. There are some on-defeat rape scenes, but there is also plenty of sexual content where the protagonist initiates.
Tara's Liberation or Alexia's Return also has a protagonist eventually making a pact with a goddess (stolen from ToT). As the story progresses, we see both Tara's sexual appetites and her power grow.
