Over The Pants Squeeze Job
Subtle, but pleasant, squeezes on your dick while wearing pants.
Non-violent handjob (handski) with pants on.
Cumming is not necessary.
In some situations, OTPSJs are essential due to convenience and where you are with and who is in the room (if anybody).
I was watching a show with my girlfriend, and we we're snuggling under a blanket, but her mom and little sister were across the room watching the show as well. Therefore, a quality OTPSJ was performed and it made the show that much more enjoyable.
The act, better known as an "over the pants handjob," occurs when one partner, engaged in a heavy petting or makeout session, vigorously rubs their partner's package from above said partner's pants/shorts/slacks/jorts. It can be used for mutual pleasure and/or sizing up a new partner.
The Flying Pacheco used the OTPHJ to get to know her various conquests before getting her hands dirty.
