Not knowing anything about the two women, I would have to predict that Gail takes it to Karen and gives her a good beating. Karen appears to be a bit of an exhibitionist and, from my experience; such women usually can't back it up if called out by another woman. I agree with those who feel that Gail is not 126 lbs. While not as heavy as Karen, she does pack on more weigh and I actually think that she is in better shape than Karen and carries her weight well. Judging from the third side-by-side picture where Gail is dressed modestly, I can see, in her eyes that she would take no sass from another woman and would not be afraid to get down and dirty.
In this fight, I believe that they start with the standard standing hairpulling contest and where they pull each other around the room for several minutes until Karen is finally able to trip Gail down to the floor. It is a twisting fall and Gail ends up on top and lands several good punches to Karen’s face but is unable to hold the advantage long enough to finish her off. They begin a roll-around and take turns gaining the advantageous top position. Both of them lose their tops as they grapple on the floor and grab each other’s boobs. Finally Gail gets on top and holds the position and starts punching Karen in the head, face and chest. Karen twists on to her belly to prevent further injury to her face and Gail wails away with punches to Karen’s head, back, arm and ribs as she straddles Karen's waist. The sharp report of fist hitting firm flesh is evidence of the power of Gail’s punches. Karen, who is not in the greatest shape soon runs out of gas and covers her head and face with her hands as Gail continues to pummel her. With her fists becoming sore from the barrage of punches, Gail grabs Karen by the hair with both hands and yanks and twists Karen's head in an unnatural and painful 105 degree angle and starts hitting Karen again in the exposed right cheek and breast. Karen, already sporting a swelling and discolored left eye, is taking a real beat down but refuses to submit. Gail, in frustration, stands up, kicks Karen several times in the right buttock and thigh and then kicks her to the belly; a kick that doubles Karen up in a fetal position causing her to moan in pain. Gail drops hard onto prone body with a loud smack. Lifting up, she brings her right knee down hard into Karen’s right thigh. She repeats the knee punch several times each time eliciting a loud painful moan from the fallen beauty. She then body slams Karen several time knocking the breath out of her. Straddling Karen's waist, Gail resumes her beat down asking for Karen submission. Karen, stubborn and embarrassed, refuses to submit.
Rather than seeing his girlfriend beat up and risk further damage, Karen's boyfriend throws in the towel. Gail stands up and raises her arms in a well earned but surprising victory. She then bends down and relieves Karen of her panties, picked up the torn bra and presents them to her boyfriend saying: "I told you that she was all talk. She doesn’t look too tough now, does she?”
