its about brother and sister
at first i think theres a scene where the sister caught the brother having a porn magazine where the girl in magazine looks like her sister, then sister got mad and go out
then brother on a date at park at night about to have sex (i think) when her sister with her boyfriend also on that park
the sister then sit kinda near her brother then proceed to have sex with her boyfriend, but half way she's asking her boyfriend to roleplay as brother and sister
sex happen both brother and sister while looking at each other
and then when its over both came home, and the ending shows her sister came to her brother room 'asking' for help for her homework
