What sort of asshole is this guy if your woman is beginning you to stop and not cum in her pussy then you should stop and pull out I'm immediately and they so your sorrry and then ask her if she wants to continue if she says yes then ask her if shes sure and if she says no then get dressed and go but don't continue if she says she doesn't want you to cum into her pussy ?
I would also pull a face, but I also love it and then it would be your face that changes when I put my cock back in you and want to cum in you again. Hope you are fertile.
