If you are experiencing pressure issues just mitigate the issue by adding acids (via special infection cultures in the balls) to the cum, or some abrasive materials (jagged kidney/bladder stones perhaps?).
If this was controlled by your Google home, it would need a battery, which would need to be recharged. Imagine saying “hey Google, turn my balls off” and getting “I can’t reach that device” because you forgot to recharge your ball switch last night…
