My girlfriend beat me at wrestling?

(I am 5'8.5 and she is 5'7.)

I 

was at my house with my girlfriend and we were playing soccer together. I beat her at it easily and she said that even though I beat her at soccer she still has way stronger legs than me. I laughed and she said "No, really" and said she'd wrestle me to prove it. I found this funny since it made no sense but reluctantly agreed.

She took off her shoes and socks and changed into shorts and a T-shirt. I started by tackling her to the ground and then she lifted her legs up around my head and squeezed it with her skinny legs. She then got on top of me and lifted her legs up above my face and dropped them and held my head down below the upper part of them. I tried really hard to get up but her thighs were far too strong. Eventually she lifted them off of me and sat on my chest and said how she's going to humiliate me. She lifted her feet up and put them right down onto my face. I tried lifting my head up but struggled and she ended up holding it down. After that she taunted me and said "How do my feet smell, foot boy?" And "How could you have ever thought you were stronger than me"?

How can I beat her? She humiliated me in a really gross way and I want to prove to her that I am stronger than her and am not any of the gross things she called me.
