My fiance often does this for other men she doesn't know, it's kind of an agreement we have that she must service other men. She quite often sucks in cars / at their house or ours on film, she fucks them too but for me it is more important to watch her have her throat degraded by big dick and listen to her choke first before anything else. Great to hear the relief from those men as they fuck her face and cum down her throat.
