Good Girl’s Anal Confession

I told him I was nervous. I’d only ever had regular sex. He was patient at first. Lots of lube, one finger, then two. I was face down on the bed gripping the sheets. When he pushed his cock against me I almost told him to stop. Then the head slipped in and the stretch made me moan. He went slow. I pushed back. By the time he was fully inside I was dripping onto the sheets and telling him not to stop. He fucked my arse properly after that. Deep, steady thrusts that made me feel stuffed and filthy. I came once just from that. He reached under me and rubbed my clit and I came again, harder, clenching around him. He finished inside me. I felt every pulse. Afterwards I lay there leaking and stunned and already wanting it again. I used to think I was a good girl. Now I know better.
