definitely in the mouth.....although i do get a lot of satisfaction cumming deep inside a gf/so,knowing she wants my cum inside her,and feeling that connection at the moment i cum........not a gf/so, then the mouth is such a turn on,or her stroking me and wanting my cum on her breasts.....damn i need to get laid!!!!!
Well that settles it. There is no bad way and getting there is the best part.
For the record,,,,,, there is no bigger turn on for me than the guys face and moaning while watching him cum on me. When you are having an orgasm and it is pouring out on me, my hips are moving for a reason. I'm excited...............
