this guy keeps tagging his galleries with nipple fuck even though there's clearly none. Not sure if he's trolling or has some other objective but it's clear by now that it's being done on purpose
It might be a misstag. they MAY mean titfuck, but are using the wrong sort of tag. The only reason I don't think it's a troll or bait, is because there's a lack of titfuck tag on here.
