If he was rock hard, I doubt he could fit a cockring
Anyway, even in his trans video with Vo, he started har(er than normal) he still was limp. And at the end, his huge softie was just hanging there. She tried several times sticking his dick in her ass again, but it was so soft it wouldn't work. Her face when she looks at the camera is priceless
A bit off topic: that being said... i have said this before: Every man at one point in his life will lose erection quality eventually. If you have a small dick, you end up with a small limp dick. But if you have a huge dick, you still have a big dick at the end of the day.
