So let me start with a little background. My name is Andy. I’m the youngest of 4 with 3 older sisters. You might be thinking because of the category this is about some massive ffmf with my three sisters but it’s not. Actually my two younger sisters are butt ugly and for lack of better terms, bitches. My oldest sister, Jen, on the other hand, she’s a pretty good looker. She has always taken care of herself and now even at the age of 32 has a pretty nice body. She’s about 5’4” and about 115 lbs with about 34B tits and round ass that’s still firm enough you could bounce quarters off of it.
I’m now 26 but this story culminated about 4 years ago. Being the youngest I always had older siblings to look up to for experiences and examples. So once I hit that age where my body started going through changes and I realized just what my dick was good for other than pissing I had plenty of material to use it for. Of course I found the stash of girly magazines that my dad had stashed downstairs and managed to sneak a couple out of the stack to keep my hand occupied but I slowly started finding something better to make my time worth it. Jen is 6 years older than me, so when I started jerking off all the time it was right around the time that she was really beginning to explore and blossom in her sexuality.
It was also around that time that her lingerie choices started switching from the usual plain cotton panties my parents got her to more seductive and revealing panties. I noticed when I would help with the laundry that she started wearing all kinds of silk string bikinis and then it started to become more sexy thongs and ones that were basically just a strip of dental floss wedged between her ass cheeks. She would from time to time have her boyfriends over during times my parents weren’t here and it didn’t take a rocket scientist to figure out that she was getting her times worth every time they came over.
As I started seeing more and more of these panties I also started realizing that they always had a sweet arousing smell to them. So I would start slipping a pair into my pants and taking them to my room and wrap them around my dick and get a good jerk off into them then slip them back into the laundry next time. I never really had any sexual feelings toward Jen it was just her sexy panties provided a good hard cumming. She never seemed to notice that a pair was missing now and then so I just kept going until she moved out.
She moved in with her boyfriend Chris, who she had been dating for quite a while. I had to give up on enjoying her sexy, well worn panties but every time she came over I still tried to sneak a peak at her ass to see if I could get a hint at if she still hiding some sexiness under her jeans. I was usually never disappointed and usually ended up getting a good jerking off later just thinking back to some of those pairs.
The summer I was 14 I ended up staying with her a lot to help her fix some stuff up around her house. It usually ended up me doing most of the work while Chris went to work and then he would complain that he was too tired to do anything when he got home. It pissed me off pretty good though that while I was sleeping down on the couch I could hear my sister going nuts upstairs as he was evidently fucking her out of her mind. Just the sound of her moaning and screaming every night was starting to have its effect on my mind as I spent many nights on the couch jerking the shit out of myself.
All of that pent up frustration nearly exploded one morning. Chris had gotten up to go to work and I woke up to his usual bull-in-a-chinashop morning routine. Once he left I decided that I may as well get up and get some work done. I went upstairs to the only bathroom in the house to take my usual morning piss. As I came out of the bathroom feeling rather relieved I was hit with a sight that will forever be burned into my mental spank bank. My sisters bedroom door was normally closed but in Chris’s hurry that morning he must have forgot to close it.
As I looked in I could see that my sister was laying on the bed with the blankets pushed away. She was laying there in just a tight clinging tank top and the sexiest little thong. As she must have moved around on the bed it slid its way up and had pressed itself in between her puffy pussy lips and I could almost see everything the good lord had given her. She was laying there with her head barely on the pillow right at the end of the bed and the only thought going through my mind was going in and slapping my growing harder and harder cock across her face and getting my hands all over that pussy of hers.
I decided that I better get out of there before I made a decision I could regret so I ran down stairs and blew the biggest load my balls have ever mustered up. I decided that laundry was now a good place to start for the day as my load had pretty much soaked three or four pairs of her panties that had been down in the laundry pile.
I ended up moving back home for the new school year and Jen ended up marrying the dick Chris. They ended up moving a few hours away because of his new job. It wasn’t too far, but far enough that we didn’t see each other hardly ever. Even though Jen and I had always been closer than with the other two sisters (we joked we were adopted) we still didn’t talk all that much.
Once I graduated college I moved out and got my own place. Shortly after that Jen and Chris got a divorce. Something about him blowing all of their savings gambling. She threw him out on his ass but after a rather ugly divorce he ended up with the house and promptly threw her out on her ass. She ended up moving back home and actually got an apartment about 15 minutes from me. This was great since I now had my buddy back and could once again check out her ass from time to time. We started talking more and ended up having each other over at least once a week for dinner.
One night when it was my turn to treat she came over and we ordered Chinese. As we sat there talking I could tell something was bothering her but I couldn’t figure it out. I figured it was something that ass Chris did after the divorce but just wanted to make sure. I kept asking and she kept telling me nothing until she finally blurted out “I haven’t been fucked in almost 6 months. It’s like I’m some ugly hag now and no man would want me.”
I tried convincing her that she was still pretty damn good looking and I’m sure any number of guys would love to get in her pants if nothing else. Her only reply was “you’re an ass. I’m sure you’re getting all the action you can handle.”
I laughed and quickly corrected her, “I haven’t gotten any in quite a while either, Erica and I broke up a couple months ago.” She didn’t need to know it was barely a couple weeks ago, but it would at least help her to feel like she wasn’t the only one.
She was still on her pity-trip though just telling me, “still, at least you had some. The most I’ve had since Chris was a one-night stand. Goes to show I’m not even good enough for a second round.”
Again I tried consoling her, “you’ve got to be kidding me. You are beautiful. You’ve got a drop dead gorgeous body that any guy would be out of his fucking mind to turn down. Plus I’ve heard you in the bedroom, if nothing else I’d at least stick around just for the evidently incredible sex.” I realized afterwards that it wasn’t probably the nicest thing to say since it didn’t really appeal to anything more than her fuckability but she didn’t seem to notice.
The look in her eyes changed from one of hurt to curiosity.

She looked at me and softly said, “You mean that?”
“Yeah, of course I mean that. You’re a great person.”
“No, about my body. About it being gorgeous?”
Before I could even say a thing she came around the table and planted the most passionate kiss on me. I couldn’t even think before I felt her tongue trying to slip into my mouth so I without thinking let it. She sat down on my lap and just kept kissing me. She finally let go and stood up and tried apologizing. I stopped her mid-sentence and told her I was fine with it. I stared it by telling her I thought she was sexy.
I couldn’t begin to tell her that I was totally up for whatever was running through her mind so I figured the easiest way was to show her. I walked over to her and grabbed her ass and pulled her close to me and kissed her again. She was pushing herself against my fast growing bulge in my pants. She pulled back saying, “Seems like you’re getting a ‘little’ problem there!”
“You have no idea. If it wasn’t enough what we’re doing now just grabbing that ass of yours would probably blow a hole in my pants.”
“You like my ass?!” she says as she grinds it back into my hand.
“You better believe I do. I’ll be honest with you since we’ve already gone further than I ever imagined. I used to check your ass out all the time to see if you were wearing a thong because I used to beat off in your thongs because they were always so fucking sexy.”
“I figured you did, I always wondered why I would be missing a pair after laundry was done or why they always had wet spots when I would go to put them in the wash. It actually turned me on some that I thought it was you getting off to my panties.”
I thought I was standing there dumbfounded until she said, “I’ve got a little treat for you.” With that she turned around and undid her pants and slid her jeans down to reveal her perfect ass . But the best part was that wedged in between those perfectly round cheeks was the sexiest little leopard print thong I had ever seen of hers. She bent down at the waist to push her pants to her ankles and my only reaction was to drop to my knees behind her and bury my face in her panties. They were tight enough that you could see the outline of her pussy mound and I just started licking and sucking anything I could through her thong.
Jen just kept moaning as I went ballistic on her panty clad pussy. She finally reached back and pulled the tiny string to the side so I had the first taste of her sweet pussy. I started nibbling and sucking and licking everything I could. I also started licking up to her puckered little asshole. (while snooping in her room before I found a ‘take it in the ass’ video so I knew she was no stranger to taking it up the backdoor) I thought she was going to explode when I buried 2 fingers in her pussy while my thumb rubbed her clit and my tongue caressed and probed her tiny rosebud.
It seemed like only a couple minutes before her hips started bucking back against my face and I got my first experience at my sisters orgasm. Both of her holes tightened up and she bucked and moaned louder and louder. I felt her juices running along my fingers so I moved from her ass back to her pussy and lapped up the sweetest nectar I have ever tasted.
When her orgasm finally subsided she turned around to kiss me and taste herself on my face. She then reached down and undid my pants and freed my aching cock. I’m not huge, about 7 ½ inches but fairly thick, and she just grabbed it and I immediately lost sight of it as it disappeared between her lips and 6 inches quickly vanished down her throat.
Luckily I’ve developed some good stamina because with as good as it felt I wanted to fill her stomach with my cum so bad but I wanted to enjoy every second of it. After a couple minutes she decided there was a better way to do this. She guided me to the ground without ever taking my cock out of her mouth. She then kicked her pants off and turned around and straddled my face, pushing her pussy back onto my mouth. We continued like this till she had another orgasm and I couldn’t take it after that and blew a massive load down her throat.
After she sucked up every last drop she looked back at me over her ass and asked me how it was. All I could do was sigh. “I guess that says enough little brother. Good thing you’re still hard. I’m not done yet!” She then slid down and my eyes about blew out of my head as I watched her incredible pussy lips slide down the sides of my cock. She had never taken the thong off either which I must say made the view that much more amazing. It felt like warm wet velvet as she took ever inch inside her. She then started rolling her hips up and down and I watched in sex-crazed awe as my swollen prick slid in and out of the best pussy it had ever been in.
She then turned around so she was facing me. I pulled her panties over again so I could watch her ride my cock. I then pulled her to me as she took her shirt and bra off as I took one of her perky nipples into my mouth and sucked nice and hard. We then rolled over so I could drive into her and force her into another orgasm. After that she got off and got down on all fours. She looked over her shoulder at me and in the sexiest tone I could ever imagine said, “Fuck me like the bitch I am.”
It took my no convincing as I again pulled that sexy ass thong aside and plowed my dick balls deep into her in one stroke. I held her by the hips and just pounded her deeper and harder with every stroke. I also started teasing a finger around her asshole and slipped my thumb into her ass which instantly threw her into another orgasm. I then pulled out and figured if I’m going, I’m going all the way and without warning pushed the head of my dick into her ass. She screamed out in pleasure and threw her hips back forcing the rest of my length up into her ass.
I continued to fuck her ass with reckless abandon as she orgasmed two more times. It amazed me that someone could orgasm that much but I wasn’t about to stop her. I started feeling that tingle building in my balls and screamed out to Jen, “I’m gonna cum, fuck I’m gonna cum. Where you want it my sexy little bitch?”
“Oh god, fuck, fill my ass up. Cum in my ass and fill me uuuuuuuuuuppp” She could hardly get it all out as I went over the edge and started blasting a geyser into her ass. It seemed like forever till I was done cumming. By the time I had finished it was running back against my balls and down her thighs. She pulled off my dick turned around and blew my mind when she took my dick into her mouth to clean it off. We then curled up right there and drifted off to sleep.
The next morning after we both slept in we fucked again and then talked for a while. We decided that it was senseless for us to both keep our apartments when I had an extra bedroom, so Jen moved in a week later. And thankful to say, the extra bedroom is still the unused extra bedroom. Now I don’t have to jerk off listening to Jen’s moans and screams since I’m the one causing them!
“Yeah, of course I mean that. You’re a great person.”
“No, about my body. About it being gorgeous?”
Before I could even say a thing she came around the table and planted the most passionate kiss on me. I couldn’t even think before I felt her tongue trying to slip into my mouth so I without thinking let it. She sat down on my lap and just kept kissing me.
