A silicone injected cock is a silicone injected cock. Silicone is injected under the skin to add volume. Some have silicone more soft and I know of others with harder silicone. There are also that have silicone and pump. It depends on the guy and the amount they've injected. Some overdo it. Some use trimix. I've been fucked by a daddy with a siliconed cock. He was around 9 x 8.25". Was some of the best sex I've ever had. Felt amazing.Wouldn't a silicone injected cock be mostly just inflamed skin or something? So it would look huge, but since it's all just skin, it'll be so soft/not feel that good?
I dunno, that's just my understanding Or does it actually get "rock hard"? Most of these videos just show the skin is being sorta squeezed by the bottom's ass more than the ass being "stretched".
