Shadow fucking is defined as having sex with your SO while you imagine fucking someone else. You get stimulated thinking about your ATF hobbyist. Your SO asks why  are you so wet ? You can't tell the truth because of the flashbacks. Priceless.

. .  . with whom the ladies are imagining fucking while having sex with their hobbyist.

That was a nobrrainer.. LOL!

I had a client some time ago who breathed so heavy that I asked twice if he was okay and he started to get annoyed so I turned around for doggie and pretended he was Darth Vader

Recently had a less than stimulating provider experience and found myself thinking about my wife during it... scared me so bad that I briefly considered retiring from the hobby

I hope for your sake the "force" was strong with him.  Should we nickname you Princess Lay-a? :P

That coulda been me... my ex complained that she could hear me breathing and once actually asked me if I could stop!  lol!  that was too much.
