you actually get interactive sex with proper mechnical systems behind it.
Provide examples.
When you win in combat, you can initiate sex with the defeated enemy:
Some enemies are eager to get fucked by you, others are reluctant. They will react accordingly during sex, acting passively or actively during their own turn, telling you to continue or stop, etc.
You start out in a standing position. You can then choose an action, while the opponent also chooses an action, in good old turn based mode. The actions you have available are dependent on positioning.
First, I remove her shoes, socks, skirt and panties to free her juicy cunt. If a body part is still clothed, you can't access it.
The woman meanwhile plays around with my pussy, still in panties, cause she can't wait. Jeez woman, calm down.
Then I switch to 69 position so we can have some nice lesbian cunt munching. You can vary the pace and intensity, being gentle or rough, etc.
As the sex progresses, both characters will gain pleasure points. Once your or the opponent's pleasure meter is filled, the character orgasms. (This screenshot is from a different encounter, if you're wondering about the different name)
Characters can have fetishes and things that turn them off, which determine how many lust points are gained from actions. If you get your opponent to orgasm, you will gain additional experience points after sex.
