Naming the movie like this may make some of you uncomfortable for some reason, but the truth is... sperm for a day at your girlfriend's house is the most standard title when it comes to the content of the movie.
I posted this movie on VLXX because it is a small part, the main reason is actress Iori Kogawa.
Going back to talking about the content of the above movie, the pepper has described the whole thing, the guy doesn't know if he is black or lucky to "catch" a beautiful girlfriend, big ass with big breasts and what is worth mentioning is very lewd. All day at her house, she "shoots" so many times, she can't "produce" in time...
