Andrew was surprised to see Zany do such a performance, because his cumshot was massive, so, for an inexperienced girl like her, it couldn't have been easy to swallow all his seed, without spilling a single drop.
Not only was he surprised, but he was somehow aroused by seeing Zany drink his cum, and his cock that had just cum, rose again as if he hadn't just had an orgasm.
Zany, after swallowing all of her husband's seed, looked back at Andrew, and watched as his cock became erect again in amazement, and couldn't help but ask, "Isn't it supposed to lose its vigor after cumming?"
Hearing Zany's question, which was obviously rhetorical, Andrew smiled and said, "Well, I'm a special case and the fact that you're so beautiful and erotic helps a lot."
