Hypersexuality Ch. 01

As she brought herself to the brink she let go of my hand and reached up to grope her tits. She squeezed hard, it seemed like she was into a little pain, and that only served to make my dick harder. Her hand moved down to grab at the sheets as her climax hit her, and her face contorted in silent pleasure. I shifted my body and rolled to the side to get a better view, and she reached out to grab my hand again at the same time. I felt the shock of contact as her hand grabbed onto my dick instead, and I gasped out loud.

"Ooohhhhh...," she moaned as she realized what had happened. To my surprise, she didn't let go, she just held onto me as she rode her orgasm down to completion.

"Hey...," she breathed at me as she rolled over and grinned at me. I could tell she was enjoying this position of power, and my mind was in overdrive as I did nothing to stop her.

"Your dick is hard pretty often, dude. Are you getting off on your little sister?" she asked.

"Well, I haven't gotten laid since before you moved in..." I responded.

"This thing is pretty big," she said while giving it a squeeze. I groaned out loud in response.

"Not as big as the dildo I bought you," I remarked as I managed a smile.

"At least we know I can take it then," she quickly shot back, seemingly without even thinking about it.

My jaw opened in response, and neither of us said anything as we both processed the moment. The hum of her vibrator seeped back into my mind as I noticed that she had never shut it off. I was battling myself internally as we maintained eye contact, but it didn't take long for my dick to make the decision for me.

In one fluid movement I threw the sheets off of us and slid up to my knees on the bed. I don't know if she was reacting or just happened to come to her own conclusion at the same time, but before I was aware of it she had slipped my dick out of the front of my shorts and was pushing me back down onto my back. She grinned at me without a word, and sucked my dick into her mouth. I don't know what I expected to happen, but I felt like my mind was exploding as we crossed the line and her tongue swirled around the head of my dick. I was fully on board the incest train now, my mind had made itself up. I knew that our relationship would never be the same, but I was beyond caring about anything other than how her lips felt sliding up and down my dick.

Her free hand was still rubbing the vibrator up and down on her clit, and her moans were felt on my dick more than heard, and I knew I wasn't going to last very long. I felt myself thrusting slightly up into her mouth, her spit was running down the sides of my dick and she smeared it as she jerked off the lower half. I still said nothing, but couldn't help but groan out loud.

"Do it," she said as she jerked me off for a moment, seemingly sensing what was about to happen.

"Doo eth," she slurred again, this time with her tongue on my cock, "doo eth, doo eth."

She closed her mouth around the head and that was all it took to set me off. I instinctively reached down and held her head in place as I shot off in her mouth, but from the way she was working it I could tell that I didn't need to. All of the sexual tension that had pent up inside me for the last few weeks spilled out into her mouth, and some even leaked out of the corners. Finally, she stopped working me, opened her mouth to show me all the cum, then made a point to loudly swallow it.

"Good fucking girl...," I moaned out to her, my head rolling back as she leaned back in to clean the remnants off my cock and tongue my balls.

"I can't believe we just did that," I said. She lifted her head up but kept jerking my dick.

"I guess I just need real dick," she said while shrugging, "the toys are nice, but nothing beats the real thing."

"I haven't even given you the dick yet, you just sucked me off like a fucking slut," I said back while laughing. I couldn't stop giving her shit, despite how nice she had just been to my cock.

"Well, you're still hard...," she said through a grin after throwing a punch at my shoulder. Her hand slid down my shaft and she started to gently play with my balls.

She was right, something about her got my dick hard like never before, I had never been able to stay hard immediately after getting off before. From then on, no words needed to be spoken. I flipped her over, and started the slow process of exploring every inch of her sexy body, thanking god that she was enough of a freak to go this far with me.

I couldn't get enough of her tits, they were bigger than a handful each, definitely more than I was used to. Reluctantly, In the interest of keeping her motor running, I moved on and grabbed the discarded vibrator. I put her on her knees and knelt down behind her so I could use it on her clit while I ate her out from behind. She tasted sweeter than I was used to, it was no issue for me to dive in and try my hardest to get my whole tongue inside her. She moaned like a whore in front of me, and I was inspired to move up and slip my tongue right in her ass. She tensed up and shot back a knowing glance, but then quickly relaxed and let me eat her out.

Her moans started to get more intense and I could tell she was close to getting off again. I reached one hand up, grabbed a handful of her hair and yanked her head back forcefully, and this set her off. Her asshole clenched around my tongue, and I slipped it out while taking care to keep the vibrator firmly on her clit.

Keeping my other hand wrapped in her hair, I slid up to my knees behind her and quickly positioned my still hard cock at her pussy. In one hard stroke I buried myself balls deep, and grabbed her ass with the hand that was holding the vibrator. I gave her no time to adjust, I just went for it and started pounding her from behind while pulling her hair.

I don't know if it extended her orgasm or just set her off again, but it seemed to take her a full minute to stop moaning loudly like a whore and look back at me. She bit her lip and gave me her best fuck me eyes, not that I needed any encouragement. I was more rough with her than I've ever been with a woman before. The taboo of our act had given me what felt like infinite stamina, and I knew I wanted to rock her fucking world.

"Fuck, fuck, fuck," she chanted each time my balls hit her clit. I broke her rhythm by speeding up and her speech slurred into another incomprehensible moan. Her pussy was the tightest I've ever had, but the massive load she had just sucked out of me kept me pacified for longer than usual. Normally I would have changed positions by now, and seeing a hint of her swinging tits below her gave me inspiration.

Without warning I pulled out and sat down beside her. She let out a disappointed groan, but yelped as I picked her up and sat her right down on my cock. She got the idea right away and slid herself down until her clit was grinding against me. I let her do her thing for a moment, she kept me buried inside her as she ground against me and I groped her ass. One of her hands was abusing her tits, while the other made it's way up to her mouth so she could suck on her own fingers.

She was definitely a sight to behold, leaning back above me as she pleasured herself with my dick. The slight bounce of her tits was hypnotizing, and her disheveled hair gave her an aura sexier than any woman I've ever seen. I watched her lips and tongue work on her fingers, and made a promise to myself to fuck her mouth again before the day was over.

I heard a moan from her that sounded like she was close to getting off again, and it broke me out of my trance. I took a slight diversion to squeeze her tits again, before heading straight back down to grab her ass.

"No more grinding, slut. It's time to ride my fucking cock," I barked at her as I lifted her up and slammed her back down. Her thick ass jiggled in my hands, and I briefly contemplated what good deeds I must have done in a past life to deserve this heaven. It only took a few strokes of me guiding her for her to get the hang of it, and she took control as she leaned forward to get better leaverage. We both moaned as her tits bounced up into my face, and I caught them in my hands as I spent time sucking on each of them.

Her pussy felt divine on my dick, I was gripped in a tight velvet vice grip and it was driving me crazy. The head of my cock was slamming into her womb, and it gave me impure thoughts about how hot it might be to give her a baby. The thought made me groan out loud, and I started to fuck myself up into her, trying to get as deep as possible.

"Do you like fucking your sister's pussy? Do you like fucking your slutty whore sister?" she spat at me as we slammed into each other.

"Fuck yeah, you fucking slut. Your pussy is mine to use now," I replied as I made eye contact with her. We both groaned together as the sweat pooled between us.

"Are you gonna cum, are you gonna cum in my whore cunt?" she breathed out. Her voice wavered, and I started to fuck her harder in response. It seemed like she was close again, and I definitely was as well. Her hands gripped the pillows behind us, and she started to lose steam as her orgasm approached. I kept up the pace, and her eyes rolled up into her head as she hit her peak. Her jaw went slack and she moaned long and loud, and I was again inspired to change things up.

Before she could come back to her senses I threw her to the side and jumped above her. I threw her legs on my shoulders as I mounted her, and slid my cock right back in her cunt. I pressed my body down into her as I fucked her hard and deep, and she never opened her eyes or acknowledged that she even noticed the change. Her sweaty tits mashed between us, and her hard nipples drilled holes into my chest. Her mouth hung open, and she continued to moan out loud and low as I pounded her pussy as hard as I could.

My resolve started to loosen as I got closer to nutting, and the added depth of our new position made me gasp out loud. She responded by reaching up to grab my face with both hands, I felt her pussy tighten around me.

Looking deep in her eyes, I lost it. We both moaned out loud as the first spurt left my cock and hit her womb, and I left myself buried deep to give her the whole load. Her sexy legs flexed under me, and her cunt got so tight that I don't know if I could have pulled out even if I wanted to.

I collapsed on top of her, not caring about releasing her from our position. To my surprise she didn't protest, and I spect a minute admiring her rosy cheeks and beautiful face. I lost track of time and we both fell asleep, my cock still hard and buried inside her.

The next morning I found myself on my side, awoken by a wet feeling on the head of my cock. I folded the sheets back and happily discovered my dick already deep in my sister's throat. My body was definitely sore from the last night, but in the moment I found it hard to care.

"Oh fuck, you don't waste any time, do you?" I moaned out to her. She shook her head no without coming up for air, and the feeling drove me crazy. I put my hands on my head and guided her to do it again, and she got the hint. I probed the back of her throat, and her plump lips felt like heaven at the base of my dick.

"We made a mess," she purred as she backed off my cock and gave the head a long, slow lick, "I had to clean it up." I laughed and slid myself right back in her mouth, guiding her head up and down.

"Lick around the head," I breathed to her. She readily complied, and a little bit of spit escaped to corners of her mouth as she bathed me with it. I let her work her magic for a few minutes before remembering my promise to myself from the night before, and moved to take action. I moved up to my knees and slid out of her mouth.

"I'm going to fuck your mouth, how do you want it?" I said matter-of-factly.

"YES," she responded with a fire in her eyes as she moved to lay on her back at the end of the bed. I put the head of my dick in her mouth as she got in position, and pulled her by her arms to slide her head to the perfect angle. I took it slow initially as I drove it back into her throat, testing how much abuse she could take.

I didn't need to worry, she proved more than capable of handling it when she reached behind me to push me deeper and faster. I got the hint and started pounding her, but still not nearly as hard as I abused her the night before.

I reached forward and took each of her big tits in my hands and spent some more time getting acquainted. I teased and abused them, pulling on her nipples as I used her throat. She took it like a champ, and I noticed the wetness growing between her legs as she moaned around my dick.

I pushed all the way in and did short, hard bounces as the depth or her throat stretched around my cock head. She grunted with each thrust and I started to lose it, her sexy body writhing in front of me. Her thighs squeezed together as she squirmed, but her hands were firmly on my ass as I prepared to unload in her throat.

"Fucking. Whore. Slut. Sister," I said in rhythm each time I bottomed out, and we both seemed to go off at the same time. I moved my hands to her neck as I came, keeping myself as deep as I could. She lifted her ass off the bed as she squeezed her thighs together, and her throat convulsed around my erupting dick. I felt like my entire soul must have come out into her throat, but she swallowed it all with another slutty moan.

Reluctantly I pulled out and stood back to admire her body. She didn't move, but made a show of licking her lips long and slow while she gasped for air.

"You really are perfect," I admitted to her, "you are a fucking sex goddess, you get me off so much harder than anyone else I've been with." She rolled over and grinned at me, blowing me a kiss as she again looked at me with her fuck me eyes.

We spent the rest of the morning showering together, and I got more intimately familiar with all of her curves. I couldn't get enough of her, but I forced myself to get to work, as money was unfortunately a necessary reality for survival.
