Mmf on LetMeJizz
Two men sharing one woman drives most of these scenes, often kicking off as a casual hangout or a couple deciding to bring in a third before the clothes come off. She works both cocks at once, one in her mouth while the other fills her pussy, then the men trade ends. Double penetration is the usual peak, her body stretched between them while they keep a steady rhythm. The whole point is watching her get worked from both sides until both loads land.
