MMD Shantae Handjob!

I know this animation isn't exactly perfect, but it was the best I could do.
Believe it or not, I tried so many ways to try and get the 2 models in just the perfect positions without any part of them clipping, glitching out, or going through each other.
For instance, I know her thumb is supposed to be behind his dick and not in front of it, but when I tried to put her thumb behind his dick, her thumb wouldn't stop clipping or going through his dick. I tried to adjust the position of her thumb, and I tried to register it to keep it in that position permanently, but for some reason it didn't work!
Also, I know there was no cumshot at the end, but that's because the head of the dick was supposed to go in her mouth, but I can't do that because her hand would just glitch out or go right through his pelvis, and we can't have that now can we?
Overall, I tried everything I could to make this scene look as perfect as possible, but sadly this is as good as it's gonna get... Rather if you like it or not is up for you to decide, but I'm just letting you know that this little animation actually did have a bit of effort put into it, and is not just one of those plain lazy automatic motions.
