On this situation i may have 'understand' the reason... the couples are now 'swapping' type... just friends... and the girls are just there jumping, dancing, grabbing each other from one side to the other... he wanted to keep his pussy closed from inside views But at least for that time that panties was way more sexiy then the grey shorts she was using
The only reason that i may found (but of course may not be the correct one) is that the house of Karol is in the middle of nowhere... With the other girl was there happens the same... 0 visitors... always there doing nothing.. the only 'sex' thing i saw from that house was the showers.. not even some bating (could have happen)
A few days ago i saw someone at Melany house (it looks kim but not for sure), but taking that no one else.. but even now the house is total lost, she only cares with the cam shows and even that are not common
They have experience on performing on cams.. and with a webcam is a lot more intimidating and with stoppage times then in a regular room not having to worry with the angle from a lousy cam all over they because they are surrounded.. They don't need to be noisier.. just need to be real
