To each their own but this is disgusting and downright wrong. It's degrading to whichever guy is not getting his knob polished at a given moment, not to mention the poor chick who is obviously eager to please but has to live with the constant guilt of disappointing someone
personally, i think its really hot to see a girl pleasing two two men at a time... there is something so sexy about a hot girl that can totally take control of two men just by sucking on their cocks and looking up at them until they cum...
