Castillos de cartón (2009)

Jose, a girl in the art department of a famous art school, has always liked Mark, a shy but talented classmate in her class, who lives in the dorm with another classmate, Jamie. One day, Jose accepted Mark's invitation and followed him to the dormitory, but when the two took off their clothes, Jamie suddenly came back, and the three had a sexual relationship that transcended secular norms. When Jose felt ashamed after sleeping with two boys at the same time, she felt that it might be premeditated: the shy Mark came forward as the bait, and then the wise Jamie joined the war and reaped the profits. But when Jose had a deep relationship with them, she was impressed by Mark's talent and Jamie's ambition, and the three began to live together. But what puzzles Jose is that although the three of them often have sex together, Mark never does it alone with her, but always likes to watch her and Jamie do it, and then reach the best part. Made her doubt the relationship between them. Jose's mother's birthday is coming, and she wants Jose to bring her boyfriend home to celebrate her birthday. Although this upset Jose, she finally decided to invite Mark and Jamie to join her. Will Jose's mother find the unusual "classmate love" of the three? Their peculiar "bed-sharing love".
