There are plenty of ways for two people to pleasure themselves. Though it usually starts off slow with some foreplay and when it finally goes down to penetration (if the folks planned to do a full package), then it progressively goes harder and harder. However, it doesn't necessarily work out like that all the time. See, some people just stick to the "beginner" pace they start having sex at. The tempo they had just after the penetration came into play. Honestly, that's fine. For them, at least. Though for most people I'd assume this gets a bit too boring. This is why people would just like to kick it up a notch and make sure they go real hard on their partner. You'll find such videos in this category. These folks like to do it rough, and I assume that you like to watch 'em do it, so go ahead.
