how did you know that they are going to unload huge loads? from experience?its important to note that its difficult to hide 3 boys cum as they are going to unload huge loads for their age. the problem is where? is it on sophia, somewhere in the room or spraying fertilizers onto the lawn from their balcony... someone who's cleaning whether it is sophia cleaning herself or whether their own mother will notices because they may leave some evidence behind.
either way it seems like sophia is expecting this cause logically putting on a show may make someone so sensitive that they end up making a mess. did she come prepared to clean herself or area that may happen on? does that bag have cleaning products? like wipes, towel or tissues. if so, it's dangerous how the 2rd boy is pointing towards the side of face, her hair, neck, shoulder and arms and her tits. the other 2 boys have a clear view of her as well it wouldnt be easy.
if she bought none will she need to sneak out of their room and go the toilet. this could be the cliffhanger that someone maybe coming up their stairs or be around the corner or be waiting outside the door.
i can just imagine l&p making it less suspenseful using tissue to clean and cover up everything. and have sophia take it with her in the bag to avoid any type of detection.
