Of use

"You... I... FUCK!" he cried, frustrated for some reason.

"Finally! Use me however you want," I replied enthusiastically. I moved onto his lap and pressed my naked body against him, rubbing his hard dick along my wet lower lips, drawing a groan from him. I grabbed his shirt and pulled it over his head. "Come on, do it, John," I said, egging him on. No way I was letting him have another of his weird freezes.

"God, I can't believe this," he said, still acting a bit weird, but at least he was running his hands over my body now. I ran one hand over his chest (not as well muscled as I might usually like, but not bad, and being used made up for it). I reached down and grabbed his length with my other hand.

"Believe it bro," I said back, trying to sound as sexy as I could. "If you want me to say it: Use me. Fuck me. My pussy is yours to use. My boobs are yours to use, my mouth is yours to use. Anytime, anywhere. Is that enough to finally get you going?" I settled his tip against my opening, and felt him lightly thrust up at me. I sat down on his dick, watching his eyes widen as his dick speared into me, slowly penetrating my depths. In one smooth motion, his entire length slid into me and his balls came to rest against my ass. I let out one long moan as he entered me finally, the thrill of him using me adding to the already significant pleasure he thick cock spreading me provided.

"FUCK! FUCK SIS!" he cried out when he bottomed out. I held him all the way inside me, waiting until he was ready to keep using me. I pulsed myself along him, and the moans I got back indicated he didn't mind me taking a little imitative. He awkwardly tried to pull out, but he couldn't get far with me sitting on him. "Fuck, that's not right," he said in an annoyed tone, and tried again.

"Do you want me to fuck you?" I asked. "I'm sitting on your lap, so either I lead or we change." Honestly I wish he would just come out and tell me how he wanted to use me.

"Damn it... I... fuck, turn over," he said, trying to twist us so I was under him. He didn't have the skill for it, and I wasn't prepared enough to help him, so he slipped out as I was flipped over. "Dang it," he cursed as his dick popped free wetly. He got on his knees and I scooched up to him, spreading my legs wide to show him my wet pussy. He grabbed his dick and pressed it downward towards me, but ended up rubbing it along my bush. He repositioned and then thrust back into me. "Oh my god sis, yeah! Fuck, I can't believe pussy feels this good!"

He stayed all the way in for a second, enjoying my tight cunt around him. I squeezed my gash around his pole, making sure he got a good feel for his sister's tightness, after all I wouldn't want him to decide to only use me this once. He withdrew, then plowed back into me, a full proper thrust this time, making me gasp, the sharp smacked our our flesh meeting filling the room as he hit bottom again. "Is that good, sis?" he asked. It was so sweet of him to ask; he could have just kept on using me regardless. I nodded and he pulled back again, and began pounding in and out. I moaned with each thrust, and he reached over to grab and squeeze my tits. I made sure to arc my back, thrusting back at him for maximum pleasure. "oh fuck Sis," he groaned. "Amy, Fuck, so good, SIS! I'm gonna fuck you better than anyone ever fucked you before!" he cried.

"Oh fuck, YES," I barely manged to get out between moans. "Just like that, bro! Fucking use me just like that. You want me to enjoy it? You want it to be the best I ever had? That's how you want to use me. Then Harder! Faster, Bro! Fucking maul my tits! Use your sister!" I cried. I felt him speed up, thrusting harder, especially when I brought up us being siblings. He groped me a perhaps a bit hard, but I didn't care. If it made him keep using me... "Make your sister howl, John. I'm gonna cum. My brother is gonna cum again! Make your sister cum hard!"

"Fucking cum, Amy. Cum on my dick, sis. Your brother is making you cum!" he yelled, thrusting even harder. I squealed in delight, getting closer and closer to cumming, harder than I ever had before, just like he wanted.

"Oh, John," I moaned, my hands flying down to my gash, playing with my clit. "Fuck, that's good. Use my pussy! So good! Use your sister's pussy!"

"Yeah, fuck yeah," he groaned. "Play with yourself as I fuck you sis! It would be even better if you were bare down there, but it's so fucking good!" he yelled. My bush vanished, since that was how he wanted to use me, and I enjoyed the feel of my hands on my bare skin as he fucked me. "I'm going to cum, sis! I'm going to cum! Fuck I'm going to cum! I... FUCK FUCK I can't cum inside!" he suddenly said, sounding panicked, thrusts slowing.

"Make me cum, bro!" I cried. "Fucking fuck me and make me cum," I gasped, so close.

"FUCK sis... FUCK!!" He yelled. "Oh fuck I'm going to cum in you! I have to stop! Fuck I have to stop! what if I get you pregnant!" he said, slowing almost to a stop.

"Fucking cum in me!" I yelled back at him, thrusting myself onto his pole. "If that's how you want to use me, then cum in me! Don't fucking pull this weird fetish crap on me now! If you want to cum in my pussy and not get me pregnant, then fucking use it like that!" I yelled. I couldn't believe he was doing this stupid routine at a time like this. "Fucking use me! Cum inside brother! Fill me with my brother's CUM" I cried as I began to cum on his dick. Feeling me cumming on him finally got him to give up on his stupid role play, and he plowed into me as hard as he could and erupted. "YES!!!!" I yelled as I felt my brother's cum shooting into me. I had never done it without a condom before, and the feeling of my brother's cum shooting deep into me was nothing like I had felt before. Even if he hadn't been using me like that, I bet I would have cum harder from him cumming in me than I ever had with Matt.

"Fuck, Sis, cumming!" he yelled, shooting more and more cum deep into my pussy. I arched upwards, breasts heaving, gasping for air in time with each spurt. He wanted to use me to cum harder than I ever had before, I wasn't going to complain! He fell on top of me as he came down, my boobs smashed pleasantly between us, his still hard dick fully inside my cunt.

"So, how was your first fuck?" I asked, after both of us caught our breaths, giggling a little at how that sounded.

"That was great, sis," John replied enthusiastically, his boner throbbing inside me.

"Thanks for finally using me. I don't know why you waited so long," I chided, making no move to stop him using my pussy as a resting place for his hard boner. And maybe hoping he might use me a little more.

"Really?" he replied with a credulous look on his face. "I mean, are you ok with me just... using you all of a sudden? Just coming in while you were doing other things and..."

"Of course, dummy. You can use me whenever you want," I replied, still not sure what he was on about. "Why couldn't you?"

"I really can't believe this," he said with an awed look on his face. "Was I really ok?"

"Oh, trust, me, you were more than just ok," I replied, grinning as I lightly ground on his cock. "Mmm, so are we going to cuddle like this? If that's how you want to use me now, I don't mind; It's nice having you in me. And you're still hard!"

"Umm..." John replied, once again looking uncertain.

"Yeah, my brother is still rock hard and his big fat dick and his cum is all the way inside me," I replied, figuring he probably wanted me to talk dirty right now.

"FUCK!" he yelled, suddenly pulling out of me. "FUCK, I came in you! Are you on birth control?"

"No, but why are you worried? You said you didn't want me to get pregnant." I asked, going up on my elbows, confused. "Did you change your mind? If you want to use me to have your kid after all, your cum is still in there. I could get pregnant right away."

"WHAT!!! NO NO! That's crazy," he yelled again. I sighed, watching his dick flag as I let his cum dribble out of me. I was just as happy he didn't want me pregnant; sure he could use me like that, but I wasn't that enthusiastic about the thought of being pregnant. I didn't understand what he was upset about, but he seemed halfway to a panic attack at this point. I needed to calm him down a bit, or at least do something that wouldn't upset him.

"Are you done using me for now, bro?" I asked in an intentionally conversational tone.
