It may seem the same if she swallows or spits, but it's not... my wife lets her mouth fill with fresh and hot cum... when she stops feeling the throbbing of their dicks and after tasting she swallows... and continues giving head (slowly) and cleaning what may have been left with her tongue... and they keep moaning!!... If she were to spit, it ends at the moment of the explosion!.. All the pleasure she gives after cumming I would not exist...
