Sister's Lost Bet

As they say, all good things must come to an end as I felt my balls about to explode from the expert blow job I was receiving from Brooke. I tried to hold out as long as I could but I only have so much self-control. When I was about to cum, I grabbed hold of Brooke's head as she bobbed faster in my lap. I lunged upwards shoving more of my dick into her mouth and began to shoot wad after wad deep into her throat. Brooke never missed a beat, swallowing it all as I kept shooting my cum into her mouth. When I was done, Brooke lifted her head from my cock, squeezed my shaft forcing more droplets of cum out of me, and licked them off the tip of my dick. When Brooke lifted her head from my lap, her face was flush and her nipples were hard.

My sister looked like she was turned on and for some reason, I blurted out, "Do you want me to do you now?"

I don't know what I was thinking. The problem was my dick was doing my thinking. I wanted to retract my question but it was too late. Brooke probably thought I was an even bigger pervert now. She was just staring at me and I got even more embarrassed. Without saying a word, Brooke stood up and peeled off her thong. Her pussy hair is neatly trimmed and her lips were visible. She laid back on the sofa, spread her legs, and motioned me to come to her with her index finger.

I ran my hands up and down her long, lean legs, up her torso to her breasts. I stripped off my t-shirt and then began to suck on her tits. Brooke pulled my head into her chest as I nibbled on her breasts. I worked my way down her body and then down her legs. I lifted her foot to my mouth to suck on her tender toes as I rubbed her lower leg. I switched legs and sucked on the toes of her other foot before kissing my way back up her other leg. I wanted to keep teasing her further so I had her turn over so I could sink my fingers into her soft ass. I leaned forward to kiss her cheeks.

"There. You've been telling me to kiss your ass for years but you never knew how much I really wanted to do it."

"Umm, don't stop now."

Brooke didn't have to tell me twice, so I began to nuzzle and nibble on her cute, sassy cheeks. I rubbed my face into the crack of her ass while kissing and licking her. When Brooke lifted her hips, her cheeks parted and exposed her asshole. I wondered if she wanted me to lick it but I wasn't sure. Regardless, I had a sudden urge to touch her puckered hole with my tongue so I swiped across it only to hear tender moans coming from my sister so I did it again. When she moaned louder and wiggled her hips, I dove in deep and began to lick her ass while she squirmed on the sofa. I tongued her ass for a few minutes but I wanted to taste her sweet pussy so I turned her over again.

Brooke instinctively spread her legs for me and I began to finger fuck her and found her pussy dripping wet. I pushed her knees back towards her body and began to give her pussy lips long, wide licks with my tongue then stuck my tongue in deep. My sister tasted divine and I began to fuck her with my tongue as she moaned and held my head tight. When I began to work on her clit, I replaced my tongue with one finger then two. Brooke was squirming to my tongue lashing, squirting her juices into my mouth as she came. I think she expected me to stop but I was enjoying eating my sister's pussy too much to stop until she came again.

By that time, I was hard again and my attention was fixated on my naked sister laying on the sofa with her legs spread before me. I never said a word and Brooke never objected as I moved up between her legs and pressed my dick against her pussy. I paused, giving her a chance to object. Okay, it was a short pause but I still waited for a split second. I slowly slid my cock into my sister knowing full well it was wrong but we were both too horny to stop. I felt the warmth of her pussy, as well as the way its tightness gripped my dick; I was in Heaven. When I was fully embedded in her, I began to move my hips, slowly at first, but gradually picking up the pace until I was fucking her hard. Brooke wrapped her legs around my waist and was lifting her hips to meet my thrusts. Her tits were flopping back and forth as I fucked her hard.

"Oh god, Will, that feels so good. Oh, fuck me, Will."

"Your pussy is so tight, Brooke. You're so hot."

I had already cum twice that day and I started to slow down on my thrusts so Brooke told me she wanted to get on top. My sister squatted over me, aimed my cock at her pussy and sat down on it, and began to ride me. Her tits bounced as she fucked me fast, groaning and moaning. My sister loved having a cock in her and I loved having my cock in her pussy. It was wrong, nasty, naughty, taboo, and possibly perverted but it felt so damn good. When Brooke began to tire, she got on all fours so I could fuck her from behind.

Brooke has a beautiful ass and it looked even better bent over as she offered her pussy to me. I slid myself into her and began to fuck her so hard, that our skin was slapping together. I began to slap her ass which seemed to make her even hotter. I grabbed a handful of her hair, tugging on it, and sinking my fingers into her ass while I fucked her.

When I felt my orgasm approaching, I released her hair and held on tight to her ass cheeks, lunged forward, and shot my load deep into her. I pulled back a little then pushed forward again several times until my balls were drained dry. I fell onto her back while catching my breath before I withdrew. My hot sister turned around to clean up my messy dick until it softened in her mouth.

We both finished our beers and then I think the reality of what we did had sunk in and we went to bed in our separate rooms. It was only then that I felt a twinge of guilt, wondering what the fuck just happened. I couldn't believe my sister and I just sucked and fucked each other. I was partially ashamed but then I realized what a great piece of ass my little sister is. I didn't remember ever having a better time having sex. Everything that happened seemed to be a natural progression to an ultimate climax. I knew it was wrong to fuck my sister but it also felt so damn good too.

I had a light schedule of classes the next day so I slept in. I was relieved that Brooke had gone to school by the time I got up. I honestly didn't know what to make of what happened between us the night before and I was glad I had time to sort things out in my own mind before I had to face my little sister again. The more I thought about what happened between us, the more I tried to convince myself that it was okay that I fucked my sister. I mean, we were both consenting adults who were horny and mutually decided to let off a little sexual steam. There was that bet we had going on and I guess I didn't have to make her pay her debt but there was nothing I could have done if she refused either. Shit, it was just a blow job, no big deal. Okay, it turned into more than that but she wanted it too so it wasn't all my fault. She was riding my dick so it wasn't like I forced her to do anything.

The odd thing was that the more I thought about it, the more I felt my dick growing in my pants. I tried not to think about fucking the shit out of Brooke but you know what happens when you try not to think of something; it ends up consuming your thoughts. Before I knew it, I had a full-blown hard-on that wouldn't go away. I ended up doing what every nineteen-year-old would have done, I jacked off before I went to class.

Thankfully, my classes and college friends kept my mind off of Brooke for most of the day. On my way home, I was kind of apprehensive about seeing my little sister again. The same things must have been going through her head like mine and I was concerned she was going to place the entire blame on me for us having sex. Heck, that's been our history together; she blames me. I was confident she wasn't going to tell our parents though. I figured this would be our lifelong little secret, never to be talked about ever again. It happened; it's over and we'll never do it again for as long as we both live.

When Brooke got home later that afternoon, I told her, "I think we need to talk about, you know, what happened last night."

"Okay Will, what's on your mind?"

"Don't get me wrong, I had a lot of fun last night but you're my sister and we probably shouldn't have done it. It's been bothering me all day and I was hoping you're feeling okay or if not, we can talk about it."

"What's there to talk about, Will? We had sex. It's no big deal. If you don't want to do it again, that's fine by me."

"Don't you think it's weird that we did it, Brooke?"

"Yeah, I never expected it to happen but, to be honest, it was kind of fun but it was just sex. We were both horny and available. You're overthinking it. I still think you're a jerk at times. I'd never tell anyone what we did, not even my best friends and you better keep your mouth shut too or we'll both be in big trouble."

"Don't worry about me, I'm not telling a living soul. It's not like I can go around bragging that I had sex with you."

Here I was, concerned that I was some kind of pervert for fucking my little sister and she didn't think it was weird. Maybe she was right, maybe I was overthinking it.

With that out of the way, I asked her, "What's for dinner?"

"What do you mean? I don't know."

"Part of the bet was the loser cooking dinner for the rest of the week so what are you cooking?"

"Are you fucking kidding me, Will? I sucked your dick and fucked you last night. Wasn't that enough?"

"Alright, I let you off the hook on dinner," I said with a grin.

"Good, because I was about to tell you to kiss my ass anyway," Brooke replied.

"You better be careful because you know I'll do it."

"If you tell me to suck your dick, I just might and I mean MIGHT, do it again," Brooke said as she walked away with a big grin on her face.

Oh shit, was she hinting we should do it again? If she was okay with it, how was I going to turn her down, after all, she is a great cocksucker. I watched her cute ass wiggling as she went to her room to do some homework. I was wondering what the fuck just happened? I thought she'd feel guilty or ashamed about what happened between us but it seems to have bothered me more than her. If it didn't bother her, why should it bother me?

Our parents left us plenty of money to order dinner when we wanted so Brooke and I agreed on burgers from a takeout place. After the previous night, I was now looking at my sister in a much different way. Even though she was wearing a sweatshirt and jean shorts, Brooke still looked good. You know a girl has nice tits when they stick out when she's wearing a sweatshirt. Those shorts she was wearing hugged her ass tightly and I couldn't help but undress her with my eyes after seeing her naked and holding onto her ass while fucking her from behind. Those long legs of hers were something else I couldn't take my eyes off of either. After dinner, I was disappointed to hear that Brooke was going over to a friend's house to work on a school project. In the back of my mind, I was hoping that she'd stick around the house and I might get a chance to explore our new sexual relationship a little further but I figured it was probably better that we didn't.

I was playing video games when Brooke got home around 9 PM. I turned my head to watch her cross the room to the kitchen. I couldn't help but stare at her tits bouncing under her sweatshirt which led me to think she wasn't wearing a bra and watched her lovely ass wiggle as she walked. I chastised myself for looking at her that way again but my dick was now in total control of my mind. I had flashbacks to her blowing me, me eating that pussy and ass, and me fucking her.

Brooke called out from the kitchen, "Do you want a beer?"

"Sure, why not?"

I ended my video game a few minutes earlier, mostly because I was distracted by Brooke. She came in to sit next to me on the sofa and put her feet up on the coffee table after she handed me my beer. I tried not to stare at her bare legs and feet but I just couldn't help myself. The more I stared at her, the hornier I got. I was trying to think of a way to hint that I wanted to fuck her again but I chickened out.

We agreed to watch a sitcom on TV that was starting in a few minutes but she went to change her clothes first. I knew I shouldn't be looking at my little sister in a sexual way but I couldn't help myself. I thought about going to bed to avoid being distracted by her but it was too early.

When Brooke rejoined me, she was wearing a large V-neck white t-shirt and I could see just a hint of her areola and pink bikini panties underneath. When she sat down, her t-shirt showed off even more of her legs than her shorts. It wasn't overtly sexy but a nineteen-year-old boy doesn't need much to get his hormones going. I tried not to be obvious that I was looking at her but I think Brooke noticed my stares.

She didn't say anything but she seemed to move around a lot more on the sofa. Any time, she moved slightly, my eyes checked out Brooke to see if I could catch a glimpse of her tits or panties. It may have just been my imagination but it seemed like Brooke was glancing over at me at various times while we were watching TV. I wrote it off as wishful thinking because my dick was half-hard just being close to someone I fucked the night before. I kept picturing in my mind seeing the back of her head as it bobbed up and down on my dick or reliving seeing Brooke with her legs spread before I ate her pussy or licked that lovely ass of hers. My dick desperately wanted to feel the grip of her tight pussy again but I truly was trying to resist the temptation of wanting to fuck my sister again.

I was sitting next to Brooke on the sofa watching some dumb TV show wondering how I would bring up wanting to sleep with her again when she said, "This show is dumb. Do you want to fuck again?"

She brought it up so matter-of-factly that I was caught off-guard.

"What?"

"This show is boring. Do you want to do it again? I'm a little horny."

I couldn't believe my ears and quickly answered, "Uh, sure."

I was so surprised that I had no idea what to do next but Brooke peeled off her t-shirt and came over to straddle my lap, offering her tits to me. I reached out to grasp her luscious globes, playing with her soft mounds before leaning over to suck on her tempting nipples. Brooke clutched my head and pulled me closer to her chest as she softly moaned. I put my hands over her pantied ass, sinking my fingers in her meaty flesh as I alternated sucking on her tits. Brooke started to grind herself against my erection and that was more than I could take. I lifted my sister and laid her back on the sofa. I looked at her half-naked body lying there before me as I took the top of her panties in my fingers and began to tug at them.

Brooke lifted her hips to help me slide her panties past her ass as I saw her hot pussy come into view. I pulled her pink satin panties down her legs and tossed them onto the floor. I never thought I had a foot fetish but I couldn't resist sucking on her toes as they were so close to my face. I ran my hand up and down the soft skin of her legs as I had her toes in my mouth. When I had played with her feet for a while, I opened her legs wide and kissed my way to her inviting pussy.

I licked around the outside of Brooke's lips before beginning to finger fuck her that hot, wet pussy, first with one finger then two. My little sister was squirming and pulling my head into her crotch but I wanted to tease her for a little while longer. I then spread her legs wider and replaced my fingers with my tongue. Her pussy tasted so sweet as I lapped up her juices. I began to finger fuck her again as I moved my tongue up to her clit.

When she was on the verge of orgasm, I began to suck and lick her clit as she squirmed to my tonguing. When she came, she lifted her hips and pulled my head tightly into her almost suffocating me but I kept eating her tasty pussy. It was satisfying for me to know I was pleasing her. After she came, I lifted my head to see the look of lust in my sister's eyes. It was now my turn and I moved myself up between her legs. My dick bobbed within a fraction of an inch from her pussy.

Brooke made the evening hotter when she said, "I need a good, hard fucking, Will. Shit, I'm so horny."

I rubbed my dick up and down her wet pussy then slowly shoved it into her while I watched her eyes roll into the back of her head.

I was thinking, "Fuck, my sister is a hot piece of ass."

I began to thrust myself into her as her hips bucked in rhythm with my motion. It seemed as if our bodies were moving as one, we were in sync with one another. I had never felt this way with any other girl I had sex with. That's what made it so special along with the fact that what we were doing was so taboo. Siblings having sex was wrong, naughty, or as we were taught, a sin. However, it felt so good, better than with any other partner I ever had. Brooke wrapped her legs around me for better leverage and I leaned down to suck on her bouncing breasts as her tight pussy gripped my cock.

We changed positions several times with me fucking Brooke from behind or her riding me. She even took time to suck my dick before sticking it back into her pussy. I tried to make it last as long as I could but, unfortunately, my balls needed to lose the sperm that had been building inside of me. I thrust myself deep into my sister's pussy and unleashed wad after wad of my jizz into her. I took some time to catch my breath before I withdrew my softening cock from my little sister's pussy.

When I sat back, I felt a bit awkward after fucking Brooke again, not that it wasn't some of the best sex I ever had but it was with my sister. I was feeling torn between doing something I knew I shouldn't have but also enjoying it so much.

It didn't bother Brooke at all because all she said was, "Wow, that was fun. You sure know how to fuck." A few minutes later she said, " I'm tired, I'm going to bed."

She went upstairs to shower and went to bed. It was just sex to her. I don't know why I was analyzing it so much. I wished I could be as nonchalant as Brooke. I was determined to quit overthinking the situation and simply enjoy the great sex.

Brooke and I barely saw each other over the next couple of days. I made plans with my friends and she had a date and spent time with her friends. She came home late when she had her date so I figured she had sex with him. I felt a twinge of jealousy, mostly because I wanted some of that tight pussy again myself. Even though I would jerk off thinking about Brooke, I was still trying to resist the temptations going through my mind.

On Friday night, despite our parents' warnings, Brooke and I had a party at our house. It wasn't one of those wild, house-wrecking parties you see in the movies, it was for a few of our closest friends. We got one of our older friends to buy us some beer and liquor and we were doing plenty of bong hits too. Most of our friends planned on spending the night, sleeping on the sofas in the living and family rooms or on the floor. My date and Brooke's date spent the night in our rooms where we both got laid.

The next morning I didn't wake up until almost noon with a hangover and a headache. My date had already left and there were only a couple of people still sleeping but once they heard me in the kitchen they got up and left. Shortly thereafter, Brooke and her date came out of her room. She was wearing one of the white t-shirts.

Her date kissed her goodbye, taking her in his arms while grabbing her ass and tits, and told her, "I'll call you later, babe. Maybe we can get together later tonight."

"I've got plans tonight but I'll get in touch with you tomorrow," she replied before he left.
