Spring a trap

The female customer sets the clothes down on the counter and states, in an overly haughty manner, "I'd like to buy these." You're not sure why, but she really gets under your skin, and you're instantly angry at her. She must just have a talent for pissing people off. Well, today, she pissed off the wrong person. You pick up the clothes, and start to scan them in, but as the female employee at your knees quietly works you towards an orgasm, you decide that your load of cum is meant for the customer in front of you. You look at the customer, and wish that she would become drowsy, and then fall to sleep, and before you have finished waving the scanner wand at her clothes, she slumps forward onto the counter. You quickly make sure no one is looking, then pull the customer forward until her head is hanging off your side of the check out counter. You pull your dick out of the female employee's mouth, push down a swath of the customer's hair, wrap the hair around your dick, and start to stroke yourself. The

employee helpfully takes over the handling, and between the customer's silky hair, and the employee's smooth hand motion, you soon cum in the customer's hair. You button back up, and the employee stands up. You push the customer's hair back down, so that she will not realize that she has a highly visible wad of cum on her head. You wish for her to awake, and stand back up straight, thinking nothing abnormal happened. The female employee finishes the check-out, and the customer goes on her way, with a sticky white glop of goop in her hair -- your sticky white wad.
