Yo I'm literally sitting here with Kinwa bugged in the back ground. She has the stamina a porn star nay a god would be jealous of. You need a save file or something? Because I like scalies but the sound effects are giving me a headache.
I think it's intentional. Hold space to drain your own hp. Use turbo badge to speed up all sex. heat also increases speed, and facefuck/tied facefuck are the fastest poses. In fact, I think they're the only two poses that are faster than the default.
