One day, he was approached by Marina, who requested his assistance in learning how to swim. It appeared that she had no prior experience with swimming at all. As he touched her body during the lesson, he experienced an erection. Marina noticed this and offered him a blowjob. When he touched her vagina, she cried out in pleasure and achieved female ejaculation. This unknown erotic ability of his suddenly flourished! With his fingers, he can make any woman - from a university student to a married lady - achieve orgasm.
