....My beautiful
JeTi thread... it's been contaminated! Lol
Okay, for starters, that bed thing, when Yuri asked why Jessica put her hand up, I knew exactly why. She's used to it because Tiffany always wants to snuggle and so she just leaves it as an open invitation.
And the reason why they're giggling is because they're totally waiting for their SOs after discussing very dirty things. It's just what bros do.
Because honestly, how do explain this

Jessi was so happy she took Tiff to the bed, almost forgetting the other two were there

This ep sure made Yulsic thread everywhere explode. 
Ha, I bet they were happy that something sparked their delusions up again :p
And remember kids,

Jessi does not want her Bro like that.
