"So, my future mother-in-law, how exactly do you plan to test him?" Wang Yue asked with great interest.
"The first test: endurance," Ling Xueyan said. "It's not enough just to have a big and firm penis; durability is also crucial. If a man can last long enough, even a smaller penis can bring a woman supreme satisfaction. But if he ejaculates too quickly, no matter how large it is, it's useless. So, you must be able to last at least five minutes under Aunt Xue's hands. Otherwise, I won't give my daughter to you."
With that, Ling Xueyan accelerated her movements, manipulating her son-in-law's large penis back and forth at a rate of twice per second.
Watching her future son-in-law's purplish-red penis move back and forth in her delicate hands, feeling its scorching heat and unparalleled firmness, Ling Xueyan's breathing became increasingly rapid. A unbearable heat spread through her body, and her legs grew wetter and wetter.
