We (that is, the universal "we") spend so much time masturbating alone that we sometimes forget how much fun it is to do with someone else. Or, more to the point, we forget how fun it is to masturbate while someone lovingly whips us.
But when you see (or better yet, do) something like this, it makes you wonder how you could ever masturbate alone again. What's the point of wearing your sexy mask and playing with your favorite vibrator if you don't have a partner to hold the cat o' nine tails? There isn't one.
