All the girls in Manojob are clearly instructed to continue jerking long after the dude shoots his load; if this is your thing consider hanjobdomination.com. It's barely professional site with some seriously skeevy looking chicks... BUT, it has several dozen scenes where the chick completely and absolutely destroys the dude for 3 or 4 minutes after he shoots his load. Invariably the guy is fully strapped down to some bench and unable to fight off; it's the dude equivalent to the hogtied.com shoots where they strap the girls down and bring out the hitachi, leaving it on maximum well after they've cum. There is one starring this chick named Mistress Eva that is almost as painful to watch as two girls/one cup. The energy that she puts into the seven minutes of blazing fast torture of the dude's johnson after he came is something to behold. Another whole series of videos starring Ashley Jane and her boyfriend are similarly squirm inducing.
In terms of other sites; most of them seem to be third tier bonus sites to a major site. I guess Tug Jobs, which is part of bangbros (a pretty good mega site), is pretty good. My recollection is that it isn't completely strict on a handjob only policy... that's one of the things that makes manojob good; they have the strictly handjob site (manojob), the blowjob/handjob site (thedicksuckers) and the POV site (mrpov). It's a great value, and if you find a chick really hot on manojob, it's likely you'll see them on the other two sites shortly thereafter... Also the behind the scenes interviews are pretty terrific.
