Female Character Models Glitching Out While Playing Animations

[SPARTAN1540]

When I start a sexual animation, the female character models start to glitch out really bad, however while not in a sexual animation the character models are perfectly fine.

Do you have a screenshot of the problem it's 10X better for people to understand what the problem is if they can see it. Me just a guess that it's not a glitch but is instead a improper skeleton being used. Do the breast stretch? If yes that is that a skeleton issue. Does the vagina spazz out? If yes also skeleton issue.
