The Paul Mitchell

This is a sexual act. Whilst trimming your man's neck hair from behind, you use your free hand to provide a reach around hj using shampoo as lube. When he's close to climax, drop the trimmer and position a conditioner bottle (with the lid removed) over his dick hole. Milk his cock into the bottle; replace lid. Immediately use bottle contents to later your own hair while he watches.

Dude, you haven't lived until your girl gives you The Paul Mitchell.
