This is a type of fantasy fight I enjoy most! Two aggressive beauties going all out to dominate the other by attacking only their breasts.
I agree this is a tough call, Sophie looks to be very capable, but looks can be deceiving and its all about the breasts and how much they can take. From my point of view I just cannot see Marlu ever admitting her tits are inferior, no matter how badly Sophie worked them over, unless she had complete control of the fight from the very start, which is as likely as the sun not setting tonight.
With both fighters in a back and forth fight across multiple rooms, each taking some sort of control of the fight at different times, I finally see Marlu punishing poor Sophie's tit's so savagely, she takes her way past her ability to take anymore abuse to her expansive breasts from the lovely hellcat Marlu, and Sophie is left with no choice but to sob in utter agony that she has the weaker tit's.
Of course the vote may not reflect my take and it may be that Marlu has finally meet her match and is just so overwhelmed at the intensity of Sophie's attacks on her breasts that poor Marlu is sobbing at the feet of Sophie, her swollen and bruised tit's causing her so much agony, she is forced to admit her tits are the inferior one's!
Thanks for the allowing me the privilege of imagining two such beauties in so savage a scenario as this one. I will be seeing the two of them battling it out in my head for weeks to come.
