Fapping It This Cumming Instant! The possibilities are endless it seems at Instant Fap.
You'll also notice there's an option to show only lesbian or straight material.
By doing this you are basically deciding what kind of porn you want to watch on InstantFap.
I have never seen this as a feature on a porn site before, but Instant Fap offers up a fuck ton of porn audio clips for you to listen to, separate from the videos.
Nothing but the best tits, ass, and pussy streamlined to one place, one site, one tab.
Where the site really starts to differ itself from others is when you click on a thumbnail.
