I can tell you one thing as a bull. I love when fucking a new hotwife and I look over and the cuck husband can’t control it and starts to cum. It’s usually after the first real guttural noises that she makes due to my size in her cunt.
That’s part of the fun to play with both couples like that is watching the cuckold hubby lose control and give in to his lust, and finish jacking off quickly because he wants to cum so hard.
then I can focus trying to keep the wife going for a lot longer so that he’s forcedd to sit there and watch her and focus on her cunt stretching as his cum runs down his limp shaft.
The other thing I’ve found, which is a big benefit for a bull and his hotwife he’s fucking, is that a cuckold husband who comes too fast, often can’t exercise self-control, and therefore it’s much easier to manipulate him into letting me do more to his wife than they planned and agreed upon
