Can Pre-ejaculate Pass Through Multiple Layers Of Clothing During Dry Humping To Cause Pregnancy?

Dry humping for approx 10 seconds over 4 layer of clothes then she sat on my lap and we hugged for 1-2 minutes. I was wearing underwear and slight thick trouser and she was wearing jeans and underwear. She was wet and i didn t ejaculated but had some precum. But after this when i checked my trouser it was dry and there was no spot or stain either on my underwear or trousers... It was her 14th day of cycle. I want to know that does precum can pass through layer of clothes? Please answer in detail
