The debate was because the 3 girls wanted to take a bath...The actual use of the bedroom as well wasn't mentioned. Of course the action may have spilled over to the bed but, tbh, from what they did in Rosie's room, would we have seen much more than that on Cam 2-4? 2-3 might have given us some interesting views though.
As for Monica and the girl's night in B2...again, would cam9 have been that much better?..girl's going down on each other are bound to block a direct in line cam, for obvious reasons. But I'm willing for them to have another go on Sofie's bed, just to prove me wrong...
