I knew this was my chance, so I walked over next to her, behind her desk. I sat down on her desk, facing her, and leaned down and found her lips and kissed her. She moaned back in approval as we made out. She gave no resistance, it was like she had been waiting for me to do this. As we kissed, I reached down and began unbuttoning her pants. She pulled away.
"No, someone will hear us. It's too risky." she said breathlessly.
"Hold on a second, I'll check." I said as I got up and went over to the door. I opened it quietly, and peered down the hall. Her room was at the end of a hallway, with no door to the outside at this end. So, it was very quiet, since it was about 20 minutes after the close of school. I stepped back in, closed and locked the door, and shut off the lights. Then I closed the blinds on the door and crossed the room back to Erin. She was waiting for me, having taken off her sweater, her large breasts heaved with each breath she took. Her white silky bra struggled to restrain her tits. She had also begun clearing off her desk, I could see where she intended on fucking! Without a word, I helped her clean her desk and immediately she was planted in the middle of the desk. She motioned for me to sit in the chair, and she began unzipping her tight black pants. She slowly pulled them down over her hips, exposing a black lacey thong, which was also removed quickly. Here she sat on her teacher's desk, stark naked, with a guy that could've been her student, waiting patiently to lick her pussy. I reached up and gently spread her creamy thighs, and pushed her back onto the desk. She was laying flat, with her ass at the edge of the desk, waiting for me to eat her cunt. I began by kissing the insides of her thighs, slowly working my way to her shaved pussy.
"Come on, Brad. God, that feels good. Keep going." she said breathlessly.
I grunted in agreement and continued to the base of her wet slit. I spread her lips open and saw her moisture beginning to drip out. I licked up the juices that had escaped and plunged my tongue into her velvet hole. I found her clit and began teasing and licking it as I moved a finger in and out of her wet cunt. She moaned and squirmed, cumming hard after a few short minutes. I gave her a few seconds to recover, as I undressed myself. My cock was begging to be used. I glanced at the clock and realized I had to be home soon. I told her to get off the desk and bend over it. She giggled and knew what was coming. She bent over her desk and spread her legs wide, her white creamy ass stuck out towards me. I moved behind her and brought a finger down and spread her little cunt lips. Next, I positioned my cock outside and rubbed it around her wet lips and slowly began to push in. She was very tight, and her cunt felt like heaven.
"Holy shit, fuck me, Brad. Fuck me hard." she squealed.
Once I got all of my cock inside of her, I started slamming her into that desk. Over and over I rammed her, while she moaned and cried out and bucked back towards me. It did not take long for us to climax, her going first, and once those velvety cunt muscles tightened around my dick, I spurted deep into her. We caught our breath for a minute, and then helped each other clean up. We dressed each other, taking great care with each others underwear. Once we had rearranged the room, and she had collected my sister's work, we moved towards the door. As I stood outside, watching her lock up the room, I realized she hadn't sucked me off. She thought of it about the same time, "Well, Brad, I forgot to give you head, after you went down on me!" she giggled.
"Next time, you'll get a chance...."
She smiled and started to turn away. My heart sank until she turned around with a devilish grin.
"Oh, I almost forgot, here's your sister's work." She smiled and turned and walked towards the main hallway. I looked down and saw on the top paper she had written her phone number and address...
