The film consists of 4 segments with different female leads, but the content is almost only one. Not long after entering the bathroom, when she came back, she could no longer see her clothes on the table, so she called her younger brother to find help. She didn't know that this was a deliberate prank caused by this mischievous cock. She was bending down to look for it very miserable, when she suddenly felt something that made her tickle behind her, when she turned around, she was even more surprised that that tickling thing was her brother's penis, she didn't know when he had taken off his pants and tucked it in. Resisting and threatening to tell her mother was something she could do at that time, but it didn't seem to be able to get things back to normal when the young man's sexual craving for puberty had peaked. Too helpless, she could do nothing more than swing rhythmically to the rhythm of sex.
