Super Bowl Sunday has been a tradition at our house for as long as I can remember. It’s like a second Christmas except there were no presents. My dad always threw a big party and the whole family typically showed up including his brothers and their families along with my Aunt Linda and her daughter Kristen. I guess we hosted it every year because we had the biggest TV and my dad just liked throwing the party - especially since me and my mom did most of the work!

I’d been at college during the last two Super Bowls so I’d escaped the annual ritual but this year I simply HAD to be home since my dad’s favorite team was playing. My mom had so much to do we even skipped church - something we normally never did no matter what the circumstances. Today though there was housecleaning to get done and food to be prepared. Fortunately my aunt and cousin showed up just after noon to help out. My cousin hates housework almost as much as I do so you can just imagine how thrilled she looked to be tagging along!

“Hey cuz!” Kristen called out as she saw me in the kitchen, “Wow, too bad all those guys you tease on-line can’t see you now!”

I just grinned back at her. I knew what she meant and it wasn’t that I was looking super sexy or anything. My hair was tied back in a ragged ponytail, no makeup, and I was wearing just a pair of sweatpants with a baggy t-shirt that smelled of cooking and sweat. Certainly not the sexy “girl-next-door” image most guys likely had when they chatted with me!

My mom must have also heard Kristen teasing me because she took a good look at me and shook her head before saying to me, “You know dear, your aunt and I can finish up here, why don’t you get upstairs and clean up before everyone arrives?”

She didn’t have to tell me twice. Give me an out from cooking and I’m out of there!

“C’mon Kristen,” I said tugging at her hand.

The two of us headed upstairs to my room where she slipped off her shoes and jumped up on my bed where she sat cross-legged smack in the center of it. She was dressed up in a yellow cami together with a semi-pleated white skirt which, when she was standing up, barely covered her ass, and now when she was sitting in this way she was giving me a great view of her pure white thong underneath. As thin and tight as it was I could easily make out the outline of her bare pussy lips underneath. Of course she wasn’t wearing a bra - I doubted that she owned one even except for a couple of special ones she used to tease guys with, and her nipples were poking through like little bullets underneath.

Kristen grinned at me and started yakking about school and some of the guys there. I envied her in some ways. Going to a public school with coed dorms and no “Lifestyle Guidelines” to follow certainly made life easier for her. Whereas I had never even so much as kissed a guy from my school, Kristen sounded like she was well on her way to establishing the same reputation in college she had worked so hard for in high school - class slut.

My cousin had always been more interested in parties than me and I wondered how she ever got any studying done with all the time she spent fooling instead. Looking at her on the bed it was obvious why the guys all wanted her so bad. She looked more like a freshman in high school than a freshman in college and if I didn’t know better I would have said she was fifteen at most instead of eighteen going on nineteen in a few months. Stripping off my clothes, I saw she was watching me as she continued her non-stop patter about her last sex party.

“Damn girl,” I said with a laugh, “give it a rest! So tell me, how do I look these days? I can’t believe I’m going to be 21 in a few weeks.”

Kristen shifted her weight to get more comfortable and in doing her so her skirt lifted up more such that essentially she was sitting on her bare ass with nothing more than the thin strip of her thong between her ass and my bed.

“Well...,” she let it drag out slowly, “I guess being a late bloomer runs in the family but you have definitely blossomed out finally. Hey, are your boobs still growing or is it just me?”

“34C now,” I replied with emphasis on the “C”.

God, it didn’t seem that long ago I was barely a B and now I was a solid C, finally. I cupped my boobs in my hands and lifted them up and let them drop. I was proud of their firmness and didn’t mind showing off a bit for her. Most of my teen years I had depended on my ass when it came to flirting and showing off my body so it felt good to have guys staring at my chest now in addition to my ass.

I leaned towards her with my hands on my knees and my bare boobs hanging right in front of her. I whispered in her ear, “You know Kristen, I’m horny as hell now and having you sitting like that certainly isn’t helping matters any!”

Kristen tossed her hair back and a wicked grin came to her face. “What’s the matter cuz, didn’t your horny daddy fuck you this morning?”

Rolling my eyes as if I couldn’t believe she would even think such a thing I replied, “You know better than THAT silly.” I paused for a second as I thought more about it and then said, “So are you going to try to do him today with everyone here or what?”

Kristen giggled saying, “Well, it HAS been a couple of weeks now so I you can’t blame me for hoping. Besides, I think it would be soooooo hot for him to do me with everyone here, don’t you? God, Aunt Shari would have a cow if she knew!”

I laughed and then quickly decided it was time to spring something on her. I was tired of hearing about her college exploits and I wanted to go one up on her for once. I smiled wickedly at her and said. “Well, not nearly as much if she knew what I was planning on doing with her son today!”

Kristen’s eyes widened and she put her hand to her mouth. “No!” she said unbelievingly, “You’ve been fucking Rick? ... Wow!” The she looked at me accusingly with her eyes narrowed, “Hmmmmmm, and so how long has THIS been going on ... and why wasn’t I part of it?

I explained how it had begun last summer and then I was pleased to see her mouth drop open when I told her how my seventeen year-old hunk of a cousin was fucking my mom as well.

“Why you little sneaky bitch!” Kristen exclaimed, “You know damn well how much I’ve been wanting his cock since I was old enough to know what it was. Mom always said we weren’t supposed to do anything with them!”

I sat down next to her and quickly filled her in on the events of the past six months or so including how I fucked my Uncle Jim as well. Kristen subconsciously started to rub herself as she listen to it all. Finally came the ultimate confession - I told her about how I had licked our cousin Tammy and how she was sucking off her brother and his friends these days.

“Damn! You’re really something else Kelly!” Kristen exclaimed, “I still want to know why the hell you guys kept this from me for so long?”

I tried to explain how my parents didn’t want to take any chances yet given that my Aunt Shari was such a prude about such things. They were worried things might get out of hand someday and someone might make a mistake and expose everything to her. THAT would be a disaster of course. I think Kristen understood but I would’ve bet anything she was already plotting how she was going to get her uncle and cousin to fuck her - and soon!

“So my secretive and naughty cousin, I suppose you want to do it with them today while your dad does me?” she asked, but from the tone of her voice it was obvious she already knew the answer.

“Well, look at it this way, while you’re doing my dad you can just think about them doing me,” I replied in a sultry voice.

Kristen had pulled her thong aside and was rubbing her pussy which I could see was now glistening with its wetness.
