She's got the tits, he's got the dick, they each want to learn what this "titfucking" thing is all about, and they need each other. You know, when you really want something, the only thing you can do is take your clothes off and hope that life isn't awkward later.
On a different note, we think the title of this video is adorable. The use of the phrase "loving it" usually brings up McDonald's advertisements, but here it just emphasizes how much these friends love their freedom and their mutual exploration of this new fangled sex act. Perhaps "loving" is the way this uploader says "fucking," and that too is precious.
