Heat.
The scrotal sac needs to be at a temperature that is a few degrees lower than the body temperature. When she holds them, she raises the heat and the body is reacting to try and get it cooler

they are able move so that they can be drawn up closer in to the body or loosened to stay farther away so the temperature can be maintained at the optimal level. (sperm production occurs at, and sperm are most active and live the longest when the temperature is slightly below body temp.) You've probably noticed that when it is cold, they a closer and tighter; in warmer temps they hang more loosely. An additional benefit of this is that if they are bumped or hit, they can move and reduce the impact.

Probably the cremasteric reflex, in which the cremaster muscle draws the testicles up closer to the body. The normal function is to keep them warm, but contact on the scrotum and innner thigh can cause this as well.

They're suspended in the scrotum. You know that item some people have on their desks that's a row of metal balls hanging by string? They're all freely dangling, and they're affected by motion around them. That's how a man's balls are also. It may be less so when they are aroused; then they tend to draw up.

The cremaster muscles moves them up.
After you've been aroused for a while they draw up in preparation for you know - their big finish.

They're afraid of her! After she's around, then they have to start working hard again to replace the sperm she just took out of you.....lol
