Assuming it's true, it fits with Rebeckah's "fisting" story,
I am not familiar with the fisting story
Do tell
Rebeckah mentioned it on her first BotS appearance. Details are thin on the ground, as Emma shut Rebeckah up very quickly, but apparently it was why she nominated Jay. However, BB prevented her from giving it as a reason, so she had to come up with something blander and more "acceptable". The assumpion is that it was a story Jay told in the house, rather than an actual "act". This in turn would fit with what we've heard Jay say previously about having his "hoop" licked, etc...
The problem with Rebeckah's story at the time was that she's told so many "porkie-pies" in the house that she's now treated as the boy who cried wolf (or should that be "girl who cried wolf-pack"? ) No one trust a word she says now, and after her "watersports" revelation on day 1, you have to wonder at her taking the moral high ground on this...
But now we have Heaven saying something similar - and you wouldn't expect those two to lie to back each other up...
