Auntie Bob and Mike spend quite a bit of time hanging out and fucking off video. In this case, he had been sucking on Mike's dick for about 20 minutes, before turning on the camera. So this is a short clip, because Mike was already primed and set to get off. Right from the beginning, you can tell he is pretty close to blowing his load. Mike gets on his knees and in typical fashion; this 18 year old fires his cum about 3 feet in front of him.
