My wife’s pussy muscles makes for better jelquing than my hand would ever accomplish. I asked her once to squeeze my cock with her hand and told her that her cunt squeezed it much harder. She then grabbed it with both hands and squeezed more. I told her that was about how strong her PC muscels were.
With my baseball bat shape, her orgasms only end up sucking me in even deeper.
Now tell me sex hinders PE!
