For me sharing my woman, seeing and hearing her with another man, or several at the same time, in the throws of incredible sex and having that feeling of pride that "she is mine" and at her will bring these other men literally to a quivering mass is a turn on beyond all else. And then to know that they are going fill her with a huge thick creamy sticky load of delicious cum kicks me into another gear. When they are done and 'dismount' and I see her swollen pussy shinny with the mix of their juices and see that first bubble of his cum ooze out of her a very animal primal instinct kicks in for me. Like a new lion claiming the pride, I feel compelled to destroy the cubs. Slurping his cum out of her makes me feel in charge, powerful, the King of the Pride, and tasting him in her and swallowing his thick load is very satisfying like denying him the pleasure of breeding her or ever having her again.
