More or less any site that is big dick(BD) specific (NO! Not interracial or str8 anal - I hate it when persons assume that is what BD refers to.).

Due to the lack of BD sites, I have some links to some truly horrid sites, yet even they convert and fairly well (as low as 1:30 but no higher than 1:800 RAW, not unique).

Surfers are starving for BD (so hungry they will buy and retain memberships to sites with fake DBs), and surprisingly enough our industry ignores their beckon... they'd rather force two lil' things (of no interest) down their throats, as aposed to one HUGE thing, straight up their sweet-spot.
