I always insist on going last. There's nothing like fresh nut juice running down your nuts as your pumping your wife's sloppy wet pussy! I always drown myself in the thought she could very well be in the process of full breeding at the very moment I'm trying to work up a last nut for her. I usually have her cleaning a cock while I hammer away for two reasons. One, so his wife doesn't catch the smell of my wife's cream from the nights activities. Two, is so I can kiss her while I get my nut. Nothing compares to tasting another mans cum while your nutting!!!
For the second guy to last so long while taking "seconds" is miraculous. It can't be her husband, as no husband can last that long after watching a sexy guy fuck his wife. Most of us only last a few strokes when taking seconds with our wives, - once we feel the warm sperm deep inside her, we cum. It's the law of the land, and the way nature intended things. We watch as she's being fucked by a guy who really turns her on and we stroke ourselves slowly right up to the point of ejaculation as she's being fucked, but we don't let it go until we enter her afterwards. It's so erotic, - a few strokes is all we can last as we experience the sensation of our penis in her warm and spermy vagina. Pure heaven. Then we slink away to leave her with her lover for the rest of the night. We won't be able to achieve erection again until the next day. Her lover is still hard. And she's conceived for us.
