From all the red on your little white gf's body, I'd say she's having multiple orgasams. And since you can't make her cum like that, I'd say she's not your little white gf anymore. He owns her pussy now.
After so many years of fucking your little penis, your wife never thought sex could be this good. You realize this is probably the first time she's cum with a dick in her pussy. You could only get her off eating pussy. Looks like that's all you'll be doing now.
You realize at this moment you are to weak to ever hold your wife up like this for the amount of time her lover has. Which by your count is 10 minutes already. How long will this go on you wonder & how many more times will she tell him he's so much better than you?
You've had the video camera set up for awhile now and you've been walking around the room snapping pics. It's all been fun and games up until now. Then, your wife tells you to put the camera down and have a talk with her. She whispers to you, "I'm his now. Thank you so much for talking me into this. You'll be a good cuckold. You'll raise our baby and everything. I know you will, because he's cumming in me right now. " Right now you're just happy her hair is hiding tears.
