http://nesaporn.com/top/june_summers_sophie_deeI dont know if this video fit here cause these could be all my subjective opinions, you will say.
I think the extremely hot Sophie Dee was a bit intimidated by June Summers bigger boobs in this video. She must be used to her famous big perfect tits being the best all the time but this time since the start, when they said their bra size, you could see the discomfort in her face. Then June started to flex her tits showing she is not only bigger but stronger, with Sophie adopting a subordinate position since then.
A bit later they had a "friendly" titfight. Im not english so Im not sure but I Think Sophie said "mash them" showing again she knows her inferiority. Afterwards they did a double boobjob and June clearly flattened Sophie tits without mercy.
At the end Sophie throw the cum to June's tits. Knowing how competitive pornstars are and how they fight for the spot in threesomes, this clearly symbolizes how Sophie knows her inferiority and gives the big spot servilely to her rival.
