10on1 is a GREAT impacting theme almost in theory; wow look 10 guys fucking 1 girl, very nice! All the attention in 1 focus (the girl) is the best! i agree with it.

BUT... in practice; while 3 or 4 guys are in action, 6 are waiting... well the 10 will alternating, but will not be more efficient a 10on2 ?
Why not a try? this can work better IF the camera handle it proper (i know in some 4somes or 3on2 we get a bit dificulty to focus 2 girls

So...?
