Niche market, totally untapped. I have a simple page up now and it's #1 "Cumming Underwater" In Google and #3 in Bing. Has made two sales @ $35 since April from Money Talks (that's the only sponsor on there). Girls masturbating underwater, couples fucking, cumshots underwater, there is a lot of potential.
$100 via epass
Domain is at Namecheap, will push for free.
Post sold with contact details or email me "gfy at xohx.com"
