I felt his surprise at my response. I surprised myself, but I had given up lying to myself about having any sort of control. He froze for a half second, before slamming his knee up into the apex of my legs, rubbing it back and forth against my opening in a frenzied manner, forcing a small groan to escape from my throat at this aggression. His hands wandered up to my little tits, squeezing them, pushing my bra out of the way without even bothering to unhook it. His fingers found my nipples and squeezed hard, causing me to gasp loudly enough for both of us to realize how dead silent it was around us.
