Be sensible.

{if Morality >35
} You're going to be sensible. You have plenty of other, safer avenues to enjoy yourself, away from Jack, from whom you have no guarantees about discretion. He may not care what Karen finds out, but you care if Jenna does.
{else
} No matter what else you may have done or not done, you have enough of a brain not to be stupid, here. Even if you aren't a saint, you can be smarter than this.
{endif
} You head to the laundry room to see if your shorts are reasonably dry. After a few minutes, you reach in and feel them, deciding that a little dampness is not a dealbreaker.
You head to your golf cart, texting Jack to say goodbye for you, and to try to be home soon, as you are making plans to go out as a pair of couples tonight, as ridiculous as that notion seems to you right now, given what Jack is probably doing at this moment.

After you return to your car, and start it, Jack responds.

Jack: yeah no problem
Jack: I'll be back at the house before 3 def
Jack: omerta, right?

You are certainly familiar with the Mafia's code of silence. More than Jack is, you are sure. He wants to be sure you're not going to cause trouble for him over this.

James: Omerta

You hit the main thoroughfare back to your place, rubbing your stiff cock through your shorts, and contemplating whether or not anyone will be home to spoil a nice porn session.
You roll up to the house around 2:20 PM.
