Last month, the pair pledged on Twitter to give all followers a BJ if the Heat won the NBA title.
Sara Jay has more than 230,000 Twitter followers, while Angelina Castro has more than 100,000.
"We're really going to do what it takes to give anyone who is a follower an opportunity to get the thrill of a lifetime," Jay said. "I am gonna be fascinated to see how many people have the balls to actually go through and get a BJ from us. We have no idea if it's going to be 10, 100 or 100,000.
"It would be awesome to break a world record for something…. even if it is oral sex."
And that's exactly what they're attempting to do. The pair have applied to the Guinness Book of World Records to set an official record.
Summer Nyte, at an event hosted by Ron Jeremy in 2005, is said to hold the unofficial record for blowjobs in a day
To get queued up for a BJ, you must follow both Jay and Castro on Twitter.
You must also be 21 or older and pay for your own STD testing from Talent Testing. Results must be submitted 48 hours before the Aug. 2 event at adult swingers club Miami Velvet.
The rules also state that participants must consent to having their BJ shot and distributed over the web, streamed live and on DVD.
Members of the star's individual sites will be first in line based on the length of their membership. Miami Heat team members, including coaching staff, are next.
Next in line will be any Twitter follower who shows up in either a "I Love Sara Jay" or "Once You Go Hispanic Don't Panic" or Sara Jay's Juicy "T.I.T.S" T-shirt.
