Chemistry Lab Kissing manual

Theresa is working in a chemistry lab for a company that produces cosmetics. She is very keen of work, as she knows how to create lipsticks and foundations and in the same time she enjoys working in a field that she has always loved. Her beau, Thomas, works in the same place and they have a rough time because they don’t want that their other colleagues find out about their love story. Could you help them kiss without being caught?
