Jeu de filles Supermarket Kissing

Joelly and Mark are two lovers, who care about each other very much. They are so in love, that they can't stay more that two minutes without kissing. Now they went shopping, but they can't stay apart and not kissing. The problem is that this market has a special policy, that doesn't allow clients to show any kind of affection inside the market. Knowing that they are permanently watched, they know it's impossible to kiss there. But if they had a little help to tell them when it's all clear, kissing would be a piece of cake. Hurry, they count on you!
