Not a bad strategy, especially when "winning" doesn't have anything to do with speed at all, but rather coaxing a hot sticky cumload out of its hiding place.
And besides, the slower this lady bubbles it to the surface the longer this dude gets to look at her awesome tits hanging just over his body. Perhaps this situation is as the video title explains (sucking a friend, husband filming) and this friend is afraid to cross over too many boundaries. If we were him, we'd twist and finagle our bodies into a position where we could grab, fondle and smack those pretty things like so many packs of deli meat. (Maybe only we do that). But if they were within reach, we'd probably jizz all over ourselves in a few seconds flat -- and there goes the race. So, slow and sensual it is. Looks like these folks were right all along.
