RCT-510 Young man "help" female student got stuck in the elevator

In the movie, there are female students wearing pretty white dresses. These girls all have a small accident: they are half stuck in the elevator and of course someone "helps". It all includes 3 segments: Segment #1: This first video VLXX likes the most because the female lead is pretty (VLXX married her, then searched for movies where she acted and discovered the genre... dirty, stuck in an elevator which you are about to see above.) Paragraph #2: Similar to paragraph #1, except the female lead is not very attractive and "acts" enthusiastically. Part #3 is the part about playing some, this time there are two guys, one in and one out, getting ready to "help" the stuck female student.
