"Of course it doesn't work," Ye Fei chuckled, and with a sudden thrust, his thick and long dick buried itself halfway into Aunt Zhang's pussy.
"Ah—" Aunt Zhang let out a small scream from the penetration, then frowned slightly and said, "Gently, it hurts!"
Ye Fei's dick could now automatically adapt to any woman's pussy, but this adaptation meant finding the maximum level of comfort for the woman without causing discomfort. For most women, especially those who weren't virgins, it was extremely pleasurable.
But Aunt Zhang was different. It had been nearly twenty years since she last had sex, so it was natural that she couldn't adjust right away.
Ye Fei had always assumed that since Aunt Zhang was experienced and had a daughter, she would be fine. It wasn't until she complained of pain that he realized he had been too hasty.
