Actually, this is "MFM"...not "MMF". MMF means the two guys are bisexual and play with each other as well as with the female. MFM is when the two guys don't play with each other...and only play with the female.
Please explain what MMMMMF is then. And MMFMMMM. And MFFMMMMFMMMMMF. If you try making a logical argument explaining the nuances of these abbreviations, you'll realise at some point that MFM, MMF and FMM are all the same thing: a threesome with two men and one woman. What sexual acts the participants do, or don't do, is not covered by those three letters.
