SFM has terrible liquid physics, I'm surprised it came out so well. Though to be honest, just showing the penis and balls pulsing would have sufficed without the white blob given how limited the engine is. Even better if they showed a bit of belly bulging growth. We could have even have bigger dick variants in the future, cuminflation, and fertilization mechanics not far behind perhaps. There's a prop for fertilization in SFMLab, though I'm not sure if the models the dev used for all the girls support belly flexes for the cuminflation. If not, they should really pay someone to revamp the models, it would suck to be limited by both the engine and model and I can't see the animations getting any better otherwise.
Overall, the climax could have lasted longer, could have done without the pull out semen on every animation arguably and could use some pulsation effects on dick/balls, but's it's probably not going to change at this point. Great sound effects and VA at least. Still probably the only rival to fredrika at this point mechanically speaking, but it's getting past it slowly but surely.
