The condom is no longer in the picture, you think Anna kept it as a souvenir. No chance, what she going to do, go to forensic labs and tell her buddies her husband is cheating on her and she wants dna tested and tarnish her reputation, no chance. Maybe she should have tasted and see if it tastes like her husbands dick, even though she doesn't know what it tastes like because she never sucked it, but she knows what Chris cock taste like and she loved every minute of it, so no chance. The reason David wants to find the stripper that set him up, is because he really liked her and he just can't believe she betrayed him in any way, that's more important to him than making it up with Anna, he is simping after the gym slut, big time. It's like this reality show that was on decades ago, when reality shows were cool and only one guy was a real contestant and all the other contestants were actors and some really hot actresses and he wins the reality show and they tell him they are all actors and the real contestant was so devasted, his whole world crashed and just couldn't believe they were actors and everyone got sad, so they never did that show ever again, that's like David he can't believe for a second she set him up and if he does meet up with her again and she confesses to him that would devastate him more than Anna thinking he betrayed her.
