Spoiler alert! Donna in 0.4.8. (Patreon)

Finally, MC can have some real fun with Donna. And he will be able to have sex with her every night, it's a separate repeatable scene, won't be in the story. So you might miss it if you just finish all the story and watch replays. Just like the sex scene for Lidith, some miss it (just go talk to her!). But I'm not saying the new stories don't include sex, you know what I mean xD.
