"I don't know." I said.
"Then let me teach you. Let me show you why old cocks are better than young cocks." He stopped sliding his finger inside my pussy, waited, then continued.
"Mmmmm. I like your pussy. It's so wet and tight!" He put a second finger inside me and slid them in and out. I moved my legs further apart and he slid a third finger in. I removed his fingers, spun me around and pushed me forwards so I had to brace myself with my arms against his desk. He bent down and started to lick and prod me with his muscular tongue. I moaned more. "I want you to beg me." I was breathing heavily
"Oh please Frank. Please fuck me!"
"Do you want me to teach you a new lesson?"
"Yes sir. I'm your student, please teach me." I whispered in a breathy voice laden in lust. His fingers found my pussy again. I felt him step closer to me. He removed his fingers and I felt his long, hard cock push against my pussy lips. He thrust his cock forwards. God it felt good. It felt like a release. I moaned loudly.
"You're lucky no-one else is here!" He started to do long, slow thrusts which made me cry out.
"Oh god! Frank. Oh god!"
"Yeah. You like this don't you? This is why old cock is better than young cock! I love your pussy. It's so tight and tasty! I can still taste you in my mouth!" His thrusts became more urgent as he thrust harder, faster. With each thrust, I cried out in pleasure. "You'll only want old cocks after this! And if I'm lucky, you might want more of my cock." He said through laboured breaths. He pulled me backwards and forced me onto my hands and knees on the floor. He pushed his cock back inside me. I was noisy but I didn't care. God his cock felt so great as it slid back and forth inside me. He fucked me like this for a short time then he pulled out. "Stand up and sit on my lap facing me." He sat in the chair. I walked to him and straddled him. I slowly lowered myself onto his very erect cock. I felt it go in me deeper and I cried out in pleasure again as I felt every inch slide against the sides of my pussy. I rode him slowly, grinding myself against him as I did. We both moaned together. He took my nipple in his mouth and started to bite hard. This made me cum and I cried out, half in pain, half in pleasure. My movements became faster. His hands were back on my arse. One of his fingers found my anus and he slid a finger inside it. I cried out more. "Horny aren't you. Like that my finger is in there huh?"
"Oh hell yes!"
"Maybe I could put my cock in there?"
"Please no, I don't mind your finger, but that's it. Do you mind?"
"No. I don't mind. But it means you might have to come by later this week for another lesson." He pushed me back into a standing position and lay me on his desk. I wrapped my legs around him as he started to slide his cock back in me again. He became frantic and pumped harder and faster. Finally, he shuddered, gave a few more short but quick thrusts and slid his cock back out. "You still look horny."
"I am!" I responded. "God I want more!" He smiled.
"That is why old cocks are better." I went to sit up but me pushed me back down. "I haven't finished yet." He inserted four fingers into my pussy. I cried out and arched my back. "Will you come back later this week?"
"Oh god yes Frank, yes!"
"Good." He made me cum two more times until finally, I was spent. I lay on his desk breathing heavily. Finally, when I had calmed down enough, he helped me to my feet and helped me to get dressed. All he had done was undo his pants and dropped them a little bit. He pulled me back into him and kissed me long and hard on the mouth, his tongue finding its way into my mouth and his hand found my now covered breast and he squeezed it. He then moved away and grabbed his things. We left and went down to the carpark. He dropped me home.
Later that week, I saw him again, and then again many times after that. The course has started back up and I'm now working in a great job, but every morning, we fuck and every day after we both finishes work. He have decided not to live together but occasionally, we will have a sleepover. We don't always fuck each other...sometimes it's other people and sometimes he insists on watching me get fucked by someone else. It's been 2 years since that evening and I wouldn't go back to any other type of cock except for old cock.
