Lady Amy trains the diver

Description: Lady Amy has a good methode to improve the breathholding capability of a diver. Facesitting!!! She steps over him, tells him how long he must hold his breath under her ass, the she deccends and seals his air-supply properly.... First for 10 seconds, then for twenty and so on, soon she reaches his limits in time, he needs more motivation.... Nipple clamp torture!!! Does it help, may be or not, but his wriggle makes fun.
