I confess I've secretly poked holes and even cut the tip of two condoms before having s** with my wife. The holes I poked were so small (little needle) that neither of us could tell they were there.
The holes I cut, went unnoticed by her until after I came inside her and she reached for the condom as I pulled out, to find the tip exposed and wet.
No pregnancy came from any of that... :/
However I think she's having an affair, I'm missing a condom from the box and I have video of her best guy friend at my house while I was at work today.... Walking her out, hugging my daughter, intimately hugging my wife and giving her a peck/kiss before leaving. How did I suspect.... Seeing his car pass me on the highway as I drove home.
