Sisters' Secret

We can't tell mom and dad everything...

I was back home from college over the summer, just in time for my little sister's birthday party. I was 20, just a few months from 21 and she was turning 18. For as much fun as we were having, it was double fun as it was her highschool graduation party at the same time. Nearly everyone she knew was here, so many people that I haven't seen in months. This was a fun time to catch up with many of them and hang out with my sister. I told many of these people about the guy I was seeing, he wasn't my husband but the guy I dated before him. He had been so infatuating to me months ago, but he was starting to annoy me a little, so I hoped going home and spending some time away would do us both good. Being able to gush about him to my old friends was helping with that too.

My sister was excited about going off to college in a few months with me, we had planned on going to the same school together. That meant the two trouble maker girls would be in college together, getting into even more trouble. But throughout the entire party, my sister's annoying boyfriend was there following her around like a hawk making sure every other guy she talked to knew she was taken. This guy was so annoying, I have no idea why my sister was with him. He was shorter than both of us, skinny as hell, like the blown away by strong wind kind of skinny. No hygiene that I could see, yet my sister was still with him. Well, I guess I was dating a nerdy white guy too, but at least he made some effort to be attractive, and he did have a big cock. But then I ran into someone I hadn't seen since highschool, my old teacher Mr. Greene. He looked exactly the same as he did two years ago. I always had a crush on him, but he was a teacher so I doubt he'd have gone for it if I tried.

He was my English teacher and the head of my student book club when I was in school. The way he'd read books, his voice sounded so sexy and he'd always read romance novels so seductively. Most guys hated his class and all but two avoided his book club. The two that did used it as a way to learn how to sweet talk girls more than anything, but it made me so horny whenever I attended. As tall as my sister and I were, each of us are 5'10" , he made us look short. I don't even know how tall exactly just that he was far above us. He was the only black man that I found attractive as a girl, but he was tall and handsome, and I knew he knew how to handle a woman. So I went up to talk to him, and he was still the seductive voiced man I remembered. We talked for a good long while and even ended up confessing about my crush on him I had. Well, I figured he'd be flattered but react awkwardly and leave soon after, but instead we found ourselves in the upstairs bathroom making out as the party went on below.

He kissed so good, I was melting. He moved his hands over me so well, too. Caressing my ass and feeling my tits through my dress. He tried so hard to fuck me and I so badly wanted to let him, but now wouldn't be the time. Just too many people and too much time left in the day to be walking around with the smell of sex on me. So I promised him if he was good, he'd get a reward and then told him to meet me later that night. I had an old friend whose parents were out of town and she was away at college still. She told me where the hidden key was and that I could use it if I needed a private spot away from my parents if needed. I told Mr. Greene where to meet and that I'd bring a surprise for him too. He agreed and we returned to the party, nobody the wiser.

I had snuck in to my friends house, the key just where she said it'd be. I waited maybe 15 minutes until Mr. Greene arrived, then greeted him in nothing but my skimpy lingerie and a robe. I had brought clothes, but changed after arriving. We kissed some more and I went for his cock when he asked what my surprise for him was going to be.

"Follow me..." I said, pulling him by the hand into the bedroom. There we entered and turned the lights on to reveal my little sister standing in matching lingerie. I walked next to her and we removed our bra's together, showing off our firm, perky tits to the sexy black teacher. We removed our panties as well and let our bodies be exposed to him fully. He reacted just the way I hoped, with a cock bulging out of his pants without protest that he was my sister's teacher just five days ago. He was 32, I was 20 and my sister 18. All of us had graduated and he had no official authority over us, so he couldn't get in trouble for fucking us.

Let me say we were quick to get on our knees and out of his clothes. His massive black cock was a thick rod between my sister and I's lips as we kissed each other and sucked his shaft up and down simultaneously. We were ravenous, cock hungry bitches fighting over who got to suck his cock more. At least until he laid down and I sat my pussy over his face, grinding my mound over his lips as my little sister took care of his cock by herself. His tongue was better than my boyfriend's cock by a mile. I broke up with him mentally when I hit my first orgasm from his tongue action. My grinding pussy orgasmed on his face, squirting juices all over him. But he just lapped it all up like a thirsty dog.

That's when the fun really started. He threw me down, literally threw me like I weighed nothing, and pinned my peachy white legs back. He rammed his cock inside my pussy and blacked me for the first time, filling my cunt in a way it never had been before. As he fucked me, hard without mercy, I remembered all the sensual moments we shared in class, and asked him through my moaning if he had ever fucked a student before.

"More than you'd believe. I'd have fucked you year ago but you didn't get my hints so I stayed clear." he said,m his cock inside me.

"Really, like who?" I asked.

"Well all the girls from when you were in book club. I fucked Trisha McCallister most days after class, Becky Sullivan didn't do a minute of homework but used her pussy to get an A+. Hell, Kathy Smith even fucked me once to pass a test during study hall." He said, listing name after name of girls I knew and went to school with, realizing they were all bigger sluts than I thought.

"Wait, Kathy Smith is a lesbian? Everyone knew she was going out with that Japanese exchange student." I said as he rearranged my guts with his powerful black cock.

"She was a lesbian, maybe still is a little bit, but she fucked me good and hard. Last I heard she was pregnant with her new black boyfriends baby." he told me.

"Well if you fucked her this good, then I understand why she'd switch sides." I said with a giggle.

He turned and pulled his cock from my pussy and inserted it into my sister's. He just slide right in like her pussy was molded to his cock. She moaned like a whimpering little slut, writhing as he fucked her.

"Cora, I'm so glad I get to fuck you one more time before those college boys get to you, you had the best pussy this class..." Mr Greene said as I looked at my sister inquisitively.

"You mean you two have fucked before?" I asked.

"Well yeah, I fuck him after class on Friday's and he curves my grade. I keep Tyler around as my boyfriend so people don't get too suspicious. I've never fucked him, not even sucked his cock. I told him I'm a waiting till marriage girl. All the while I'd make out with him after swallowing Mr. Greene's cum." she said giggling and smiling as she got rammed.

Damn, even my sister was a slut. But right now, so was I, and I didn't care a bit. We traded turns on his cock, my sister even letting him fuck her ass. It was so great I forgot I even had a boyfriend. Mr Greene made us grind our pussies together while he jerked off to us. Two slutty sisters grinding our pussies together. He may have told us to grind pussies, but the kissing and the sucking of each other's perky titties was entirely our own act of sexual deviance. We moaned sexy words of encouragement as we took turns fucking him after all that. Tonight was like finding the janitors key ring and going through opening all the doors to see what's inside. My first black cock, my first incest with my sister, my first lesbian experience. My world and mind had expanded, but it expanded so much more when he inserted his powerful cock in my asshole too. Even though my ass belongs to my husband now, it was BBC that took my anal virginity. So many things that happened this night that wouldn't happen again for years to come.

I was begging like a whore for his cum in my pussy, but my sister won out. She held her legs wide for the gooiest creampie I had ever seen. I didn't know a man could ejaculate that much cum in one load before, at least not till I met my husband. I've never eaten pussy in my life, I wasn't a lesbian at all. But somehow seeing the white load of sperm oozing from my sister's pussy was like a magnet for my mouth. I tongue fucked her cunt the way I wished a man would do to me, sucking the cum from her hole clean. With our pussies clean and well fucked, his cock thoroughly satisfied, and plenty of orgasms for everyone, we fell asleep on either side of him.

I didn't know it then, but my love for BBC which started there, was overshadowed by my sister's. I married a well-endowed white man and I'm glad I did, because he let's me fuck black guys on the side. But my sister would end up marrying a black man after college and getting knocked up three times from him. My dad resents her for being a "coal burning slut" but doesn't know that both his little girls have been blacked multiple times. While that may seem racist, and it is, my dad was raised in the south so it's the way he is. I still love him, but understand too that in my hometown, there's only one interracial couple. That's Mr. Greene and his white wife, our highschool sociology teacher. She clearly doesn't know about her husband fucking all his female students, and if the parents in our town knew how many of their daughters had gotten blacked there would be a riot.

As far as I know, no one found out, and the blacking continued in secret, perhaps a long held tradition amongst the generations of white girls we keep to ourselves. After that night, I broke up with my boyfriend, and a few years later I'd meet my husband, as I told about in a recent story. I know my mom was resentful about my dad's racism though as after their divorce, she had a threesome with two black guys. The bond between my mom and I is strong enough to confess our sexual encounters in detail. Maybe I can tell you more some other day...
