Fully understand the women who have access to a cock that is huge... My mate (OK ex Mate) was huge, his wife would only wank him off, so he would play the field, big time. Most ladies would swoon at the size but only a couple could take all or most of it. He was happy getting it away from home, which left his Mrs wanting. Thats where I stepped in.
Not sure how we got on the subject but one day when I had popped round to see if he fancied a pint, only his Mrs was home and she started telling me just how frustrated she was. So, I took her for a drink instead. He was not coming home that night, so I stayed. Fuck she was insatiable, I was the only other cock she had ever had and she could take it all, I am no Monster with around 8" but she just lapped it up, so to speak.
He left her, after he found a woman that could handle him. I fucked her at least once or twice a week for several years.
So I guess the moral of the story is don't wish for a 12" Penis....
