You can perform the pocket maneuver when you are in a classroom or at
work. Say you are sitting in your chair, and you feel a boner coming,
pull the pocket of your pants out and feed your cock through the pocket. This
will kind of hide your erection but it does feel very nice. This technique works the best if you are wearing boxers and athletic shorts/pants.
Your Friend - "Crap, I'm starting to get a massive boner."
You - "Oh no problem, just
pull The
Pocket Maneuver and it
will hide it AND it feels cool. I'm using that technique right now."
