We were greeted by the Head Mistress, Mother Superior. She introduced us to Father Tom and to Sister Mary Margaret. Sister Mary Margaret was to be my ...omeroom teacher, she taught Religious Education. I tried to listen to the long list of rules but I got bored and kept looking around the room. Dad signed a few forms and handed over a check for my tuition. Then Dad was escorted out to his car. Sister Mary Margaret took me to my first class.Sister Mary Margaret was young and had a pretty face,. He asked if I needed any help and I told him I had things under control but he didn’t leave. I kept on loading my purchase into the truck and he stayed there standing behind me. I noticed that he would alternate between looking at my tits and my ass, depending on which way I was facing.Now I didn’t get dressed up real fancy just to go to the store. A thin white cotton tank top cut off jean shorts and a pair of slip on tenny boppers. If I remember right I was about a 38-40D back then and that. Fuck, was this going to happen? Everything I'd wanted for so long? My cunt began to tingle anew at the thought, and I felt myself grow even wetter, juices slicking the inside of my pussy, making it ready for him to thrust inside. Fuck, did I actually want this? My breathing grew heavy, and panic began to curl in my stomach, to match the lust curling in my chest. It was so terrifying, feeling his eyes on me. So wonderfully, terribly terrifying. "Does anyone know you're here? Is there anyone in. " Are you sure?"You clench your ass around me, tight. "I'm sure."I let out the breath I didn't realize I'd been holding and take your hips in my hands. I pull back slowly, alert to any sign of pain on your part. There is none, and I push back into you, burying my cock deep in your tightness. You grunt as I fill you completely, but that's all.I fuck your ass… slow… deep… filling you with every thrust. Beneath me, you twitch and writhe and moan. You push back impatiently, making me fuck you.
