Neighbor's daughter caught

My neighbor was away on business for a few days, so she asked me to keep an eye on her daughter Anja. When I went into her room with my friend, she was lying in her bed. At some point, I noticed that something was moving under her covers that clearly didn't belong there. This little tramp... as soon as her mother left the house, she made the dolls dance. But what was I supposed to do with her and the guy? Anja and my friend then had an idea..
