As Barbara is distracted, you slip your leg around her left leg and bending down, you push her panties aside and starts to finger her pussy.

"I see your training has got you better at that."

"Yeah, also this!" You grab her foot with both hands with your leg still wrapped her leg and pull forward.

Barbara falls on her back as you stand over her holding her leg in a hold.

"Now, what?" Barbara smiles.

"Now, I'm going to make you tap out."
