You have a serious fixation, young man! The secret of safe sex with GMILFs or GGMILFs is to consort only those who haven't had sex in the last twenty years. This may require some gynecological inpatient surgery before commencing, unless you are smaller than I am.
As to your inquiry as to my piscine nature, it is true. I live in a very large fish tank and type on a waterproof keyboard. The "whiskers" help a lot. My owner is a very kind trader who throws me tasty morsels of uncooked of stray cat several times a day. He is also very generous to let me post on ET with other shit-eaters.
