Yup, I've known many a female that that would say NO when they really meant YES. i remember one particular girl I dated in college and I was trying to get in her panties. She was a freshman and supposedly dating some guy from back home and said she loved him and had never had sex with anyone but him. She tried to make me think she was so "devoted" to him. I finally convinced her that oral sex would not be actually cheating on him, so she relented to that. I ate her pussy to 4-5 good orgasms and she started begging me to fuck her. She made me promise I wouldn't cum inside her, so I started fucking this chick, she popped a couple more orgasms and was in the middle of another when I told her I was going to cum. Instead of lifting off me, she locked her legs into mine and pressed hard against me as we both cum. Afterwards, we were laying there and I thought to myself, "yeah, that devotion only goes cunt deep" ... when that pussy starts screaming for attention, the same thing that happens to a man, happens to a woman ... their brain goes from their head to their crotches, fuck all common sense, and its "Katie bar the doors" time. I fucked her twice more that weekend, cumming inside her both times.
