Reiko had been in agony after not having sex with her husband since he developed erectile dysfunction six months ago. One day, Reiko witnessed her son masturbating in his room and, unable to resist, approached her son, seducing him by saying, "If you cum when you masturbate, cum inside me!!" Her son used his natural, insatiable cock to satisfy his mother's bottomless sexual desire. Since then, Reiko could no longer contain her growing carnal desire and forced her son to cum three times in a row without pulling out!!
