Tanya looked really frustrated and grabbed at her bedsheets again. This time she wasn’t cumming, though; it was pure irritation that we weren’t alone in the house any longer. What Tanya said next nearly got us busted. It was such a soft whisper, I could barely hear her saying, “Fuck, I need the D!”

“I thought you were too sore for that?” I whispered back.

“I probably am, but after the way you ate my pussy I want it anyway!”

“OK,” I responded as I guided my aching hard on to my sister’s belly and sighed as I started to sink into her sopping wet pussy. She must have really cum hard, because I had been doing my best to drink up all of her pussy juice earlier. However, her pussy had never felt wetter to me. Tanya sighed too as her body responded to my cock eagerly, but by the time I was half way inside her, she was saying, “No, Mike, no! Not like this. Mom will hear us!!” I stopped moving my cock deeper into Tanya’s body, but I didn’t pull it out. After eating her pussy, it felt so good to be inside Tanya again. “Don’t want to stop!” Tanya couldn’t control herself either, lifting her hips off the bed and pushing her pussy most of the way up my shaft. She panted, “I don’t either, but if we do it this way, Mom’s going to catch us going at it.” That finally got me to pull my aching cock out of my sister’s body with an obscene pop. “What are we going to do?”

“Just a second, we have to make sure we don’t make lots of noise.” Tanya tried to get over to her dresser, but her legs buckled before she had taken a single step. “Fuck, Mike! What did you do to me when you ate my pussy? My legs are like jelly.”

“I guess we don’t have to finish,” I said reluctantly.

“Are you insane? If you don’t do something to put out the fire you lit between my legs, I’m likely to strip naked and finger myself at the dinner table. And we’ve got the more obvious problem of you walking around with a big boner all night.” I went over to Tanya’s dresser with my hard cock bobbing and asked, “What am I looking for?”

“Find a pair of my socks. Put one in your mouth and give me the other.” Tanya got flat on her back in the middle of her bedroom floor as she said this.

“Shouldn’t you be on top? You were really good about not getting us caught when we were in the van.”

“Probably,” Tanya admitted, “but after the way you ate my pussy, even as sore as I am, the only thing I can think about is you on top of me fucking me however you want!” My sister’s words sent a thrill of pleasure through my whole body, but I especially felt it in my cock. It had to be inside Tanya again, and quickly. Honestly, I had already mostly forgotten the fear of discovery, and I wasn’t sure how I had managed to pull my aching cock from Tanya’s pussy when she had been sitting on the bed. I stuffed the sock in my mouth, more because that’s what Tanya told me I needed to do if I wanted to have sex with her than from any realization that it would keep me from yelling out, and got into position to fuck my sister again. My dick actually started to tingle; I was so eager to get it back inside Tanya as I tossed her the other sock. In fact, I couldn’t make myself wait to start fucking again. Tanya moaned, “Mik ... mmmph,” as she quickly stuffed the sock in her mouth in response to me stuffing her pussy full of my cock. At first, I was sliding it gently in and out of Tanya’s body. It was more from my cock being sore than from remembering Tanya’s multiple comments about how sore her own pussy was. However, the sight of my little sister on her back, on the floor of her room, with her tits half hanging out and my dick splitting her pussy lips was inspiring me to fuck her faster and faster. The harder I plowed into Tanya’s body, the more wildly her boobs bounced, and that just made me want to fuck her faster still. Before I knew it, we were both breathing hard through our noses, almost snorting since we had socks in our mouths to keep us quiet. I could tell from Tanya’s face that this was hurting, but she wrapped her legs around me and held me so tight that there was no chance my dick might slide free of her pussy as we fucked. My cock was hurting too, but the only thing going through my brain was the work ‘fuck’. It repeated over and over as I continued to thrust hard into my sister’s body. My little sister had said she needed my dick, and my only purpose in life was to give it to her! Of course, fucking hard and fast like that can’t last forever, especially with a babe as sexy as Tanya! I had no concept of how long we had been going at it after hearing our mom arrive home, but it was long enough that first one, then both tits bounced free of the crop top, and of course I started pounding my dick into Tanya’s snatch harder each time one of her big boobs came into view. Some time after that, I got goosebumps on my arms, and then my cock exploded jizz into Tanya’s belly. I froze, and my little sister started milking my cock for every drop of spunk I had by tensing and relaxing muscles inside her pussy. The feeling of me ejaculating inside her seemed to do something to her because her face relaxed, and she pulled the sock from her mouth to let out a long, contented sigh. I pulled the sock out of my mouth too and said, “I hope that wasn’t too rough; I know you said you were sore, but once we got going, I couldn’t control myself.”
