I've been trying to find videos of titjobs where the titjob is the one that makes the guy cum, but every one I've found has been something like:

• dude takes dick out from between boobs and fucks or strokes himself to completion
• dude is nearly bursting from something else, titjob starts and he's already cumming
• video starts with titjob ends in blowjob

I'm starting to wonder if tits alone can make guys cum...
