They didn’t seem to enjoy the lectures, although, honestly, neither did I. I guess there’s really no way to do that sort of thing without coming a...ross as condescending. It probably didn’t help them that they were the only ones fully dressed, either.Sean tapped me on the shoulder coming out of the lecture. “Hey, we’re going into town, you want to come?”“Nah, I’m going to hang out back at the dorm.”I ended up hanging out at the dorm for most of the rest of the day. Around 3:00 I got a text from. I came two more times in the span of 5 minutes.My body shuddered and shook uncontrollably. He kept pounding and pounding away. It was the most extreme fucking I'd ever had. I have no idea how long it went on but it seemed like forever. It just never seemed to end. I had two more orgasms. He was draining me of both my fluids and my energy.Finally I felt him tensing up. His cock got even more rigid in my pussy and soon he was flooding it with his black load. I actually felt it filling my uterus.. .".I could hear my sister removing her clothes."Tell me when you're naked." OK, everything is off," she said."Are your nipples hard?" I asked."Yes," she said."Touch them for me. Rub the phone against them so I can hear," I requested.I could hear my sister rubbing the phone against her gorgeous full tits."What next?" she asked breathlessly."I want you to stroke your pussy so that I can hear how wet you are. Don't put your fingers inside but I want to hear how wet you are right now," I instructed. With half of my cock inserted in her mouth she start to peel off her jeans. I raised mom by armpits and removed the remainder of her clothes while she help me to take mine off. I made her sat on my lap facing the fireplace and inserted my prick all the way into her pussy. She began to move her hips sensuously."Stand up, I want to fuck you in the ass," I said, knowing that her juices would provide enough lubrication for anal sex. Mom lifted up enough to allow my dick to slide out then held me.
