Cum porn is the kind of porn that features... cumshots. Cum play. There are all kinds of scenes here but the only constant is that there is semen involved. You will surely be delighted to see these sexy women getting covered with hot, sticky jizz. They might be giving blowjobs and then the guy pulls out and splatters his seed on their pretty faces, or maybe the girls are having their pussies filled up, but they want even more. There are different but equally impressive variations to this. The best is watching a horny lady get covered in layers of cum. Her pretty face will be painted white and there might be some semen dripping from her lips. She is completely coated with sticky spunk and she looks happy to have all that hot, sticky, tasty cum.
Of course, there are different subgenres within this genre. For example, cum on ass porn shows pretty butts getting cummed on. There's the cum on ass porn, where the men are cumming all over the women's backsides. In some of these scenes, the men will be fucking those asses and then shooting their load onto them. This might involve anal, this might not involve anal at all. The action is all kinds of sexy and there will be a lot of moaning going on. The guys will be enjoying themselves and the ladies will be loving it, too.
