You know it's funny, you never know who is the most likely candidate to be up for an affair.
The most serene, sedate and steady person may be the one who is ready and willing to have something on the side.

They may already have signed up and surfed a site such as ashleymadison or another affair welcoming dating site.

All they need is just a little push and there they are.  Are you the person to give them that push.

Are you adventuresome enough to go find out.  Have you been online searching / looking for that one woman you might be into.

Into thrills, danger are you?

Be careful what you wish for though.  Prepare well before you proceed.  Cover your rear five ways to Sunday.  If you're married double that.
