The first chick I fucked was my step-sister. She wore tons of makeup. As a result, it's programmed into my brain to associate heavy slut makeup with sex. When I see women like that, it gets me off.
For many farkers their first experience was with an older woman. Most of them have saggy tits. For some it might be the only pussy they ever got or they've only been able to get older women. So they associate saggy tits with sex. If that's what gets them off and makes them happy, who the fuck cares? Don't like saggy tits, don't look at the thread.
