The fateful night started when I showed up at his place, expecting more of the usual kinky fun. At first it did start that way, he roughly grabbed me by my hair and forced me down onto my knees as he had done often before, he forced his just barely not flaccid cock into the back of my mouth and firmly pressed my face into his crotch. He held me there for at least 10 seconds before I could feel his thick cock growing harder and pushing its way into the back of my mouth. He started to work his hips a little and I could feel every beat of his heart inflating him, filling my mouth completely and growing until he blocked off my airway, working his way down the length of my throat. His stiffness started to hurt as it pushed against the back of my throat, trying to straight itself, but he held me firmly by the hair. I tried to be a good girl and hold it, but the throb of his cock reaching its near full size made me reflexively pull away. I managed to get perhaps an inch of it out of my mouth before he caught me and slammed himself back into my mouth causing me to gag. That was all it took for him to get completely hard. It felt so tight and painful, as his cock stretched my throat, he knew would turn me on so he held it there for several agonizing moments. I loved every second of it. Finally, after I started to struggle for air, my throat futilely gasping around his cock, he pulled out. As I loudly gasped, several strands of spit trailing from my to his magnificently large cock. I always felt proud knowing I could swallow his 10 inches… I was in a bit of a daze at this point, just trying to get my breath. He didn't give me long before his spun me around and pulled my shorts down. He buried his face in my ass and began eagerly licking my asshole until finally plunging his thick tongue into it. After several minutes of his, I was ready for him and he knew it. He stood up and slowly slid his thick cock into my ass, my throat spit lubricating his cock and his spit on my ass, it was pretty smooth and not too painful as he picked up speed and intensity. He was acting a little unusual, normally he wouldn't "go for the prize" this quickly, but I wasn't going to question him. I felt him cum in my ass, spasming for several seconds before he pulled out. I looked over my shoulder smiling at him and I could immediately tell he was up to something. A moment later I felt something pushing into my ass again, it was cold and hard…. and BIG… and it kept getting bigger. I started to protest, but then I felt a sudden "pop" and the painful stretching sensation stopped. I realize he has just put a very very large butt plug in me, but I had no idea why. He bent over me and whispered "This is to keep you ready for later, now get dressed. We're going out."
