That your mother leaves you alone means that you can do whatever you want, right? Because right now he's coming to leave you with your cousin, whom you haven't seen for years. The thing is that the years don't pass in vain and the truth is that when you see her, they awaken those memories of when you played "mom and dad" with her. And seeing how she walks around the house, very scantily clad, supposedly because of the heat, and even more so when you catch her masturbating. Well, Mom would be back in a few hours, but so... I think you can relive those games of yesteryear with her, but now in a definitely adult version hehe.
