For the next few weeks, Dani and I continued fucking each other in secret. I would drive to her sorority house after school, pose as her boyfriend, and fuck her brains out. On weekends she would come home to do laundry and get free food, we would wait for mom and dad to go to bed and fuck in my room. It was an all you can fuck sister buffet.
We bought one of those sex position check off posters and went through all of them. Wheelbarrow, lotus, piledriver, sidesaddle, teabag, crazy monkey. We did the whole kama sutra. My favorite was when our parents were watching TV, and Dani invited me into the kitchen. She hiked up her skirt, revealing no panties, sat on the counter, and had me fuck her right there, just a few feet away from getting caught. When I whispered I was cumming, she got on her knees and sucked me dry before swallowing. We then went back to watching the movie on the couch with mom and dad, my swimmers still in Dani's belly.
Winter break came for both of us. Dani somehow was getting good grades at her college despite partying all the time. Don't know how, I just know she wouldn't suck my cock after her finals because she said her jaw hurt. Maybe she chewed on her pencil too hard or something.
By chance, I saw an advertisement by flier for a swingers party on New Years Eve. It would have gloryholes, orgies, even a dungeon. Masks were encouraged. One problem though, we had to show our IDs to get in, and Dani and I had the same last name.
At home, Dani was in her room reading something on her laptop, wearing pink yoga pants and a black sports bra. I showed the flier to her to get her take on it.
"Sounds fun, Mikey."
"How will we get past the ID check? They'll know we're related."
"They'll know we have the same last name, not that we're siblings. We'll go as husband and wife."
"Won't we need wedding rings?"
"Don't worry about that. Doesn't strike me as a place many people care about their vows."
The night of the orgy came, New Year's Eve. Dani and I headed out in our winter gear for the perilous journey from the front door to my car; Dani in her famous giant pink puffy coat with Princess written on the back, and myself in a t-shirt and jeans because I was not a woman. Outside, it was cold, snowy, icey, and braving all those elements would make Dani's pussy all the warmer by comparison. We told our parents we were going to a friend's house, one of Dani's slut friends that would cover for us if needed. I drove us to the address, it was an old mill converted into businesses. After parking we walked up a giant spiral stairway in a turret looking spire to the third floor where a guy let us in. Inside were more hallways and a desk with a lady wearing sheer lingerie. We walked up and greeted her.
"Members?"
"No, we're new." I answered.
"No problem. IDs and 20 dollars registration, please." Moment of truth. We handed her the IDs. She scrutinized them for a few moments. Dani then grabbed my arm and brought me in close.
"We're newliweds!"
"I would guess so at 18 and 22. High school sweethearts?"
"Oh, even longer than that!" I thought she was giving away too much information but the lady smiled.
"That's so sweet." She handed the IDs back and two paper bracelets, one pink one black, which we adorned.
"Rules are simple. Always ask consent, no means no, be polite and have fun. Enjoy!"
"Oh we will! C'mon, darling!" We proceeded down the hallway to the locker room and got a rental lock with a key on a rubber bracelet. I opened the lock and Dani took off her giant puffy lined coat. Underneath she had on just her satin teal bra and panties with black trim. From her pocket she pulled out a cheap Mardis Gras style green mask and put it on. She stuffed the coat in the locker. I left my clothes on because no one likes seeing naked men. I put on my New Years Eve style mask and locked our stuff up. We then walked down the hall to the main room. The hallways opened up to a big open room with hardwood floors and a bar. There were several more doors which led to various bedrooms, the dungeon, and a mini strip club complete with poles and stage. Dani and I went to the bar. I now realized why our bracelets were different colors, because she was over 21 and could order spirits. Though I doubt many people would mind on New Year's Eve. I had to drive, regardless, so it was not a big deal. She got a whiskey shot. The price was a flash of tits. She happily obliged. Since that was the price, she got three more by letting the bartender suck her left tit. My sister was such a whore and I loved it.
While Dani loosened up, we explored the place. It was only 10, the party went to 1 am, so people were mostly just talking and drinking. Some women were in revealing clothes, but honestly none looked better than Dani. A lot of guys were interested in her.
To help get her in the mood, I brought Dani into a bedroom that was not in use and locked the door. I pushed her onto the bed and moved her panties to the side. I proceeded to eat my sister's box for the next 20 minutes, giving her several Os. I spelled the alphabet: A is for Alfred, B is fir Batman... As much as I loved her slutty blowjobs, Dani absolutely fucking loved my oral on her. I think it was why she kept me around to be honest. I was fine with that trade.
My face still covered in sibling juice, we walked around the place until Dani saw the gloryhole room. She asked to go inside and closed the door behind us. Inside the room was all black; it had a bed, and sliding square panels on the wall that connected to the adjacent bedroom. Dani opened one of the panels and stuck her hand in, I guessed she was making a "come here" motion with her well-manicured hand. What guy could resist? Almost instantly, a hard cock poked through the wall.
Dani got on her knees to suck the cock through the gloryhole. I had never gotten oral in a gloryhole myself, but I imagine it must be an interesting sensation to not be able to see what is happening and suddenly you are getting your cock sucked by a stranger. Dani was an absolute pro, within seconds the cock was covered in aerated spit as she sucked and gagged on it. A knock on the wall and he came in her mouth. The cock withdrew.
"Next!" Dani enthusiastically shouted. Another cock replaced it. This time I got behind her and pulled her up to stand, then pushed her down into standing doggy. She sucked the cock while I entered her and pushed her forward until her lips contacted the wall. I was London Bridging my sister with a complete stranger. Dani turned her mouth into a fleshlight as I grabbed her arms and fucked her from behind. Every time I thrust into her, the impact forced her to deepthroat the cock she was sucking. Then as I withdrew, she would fuck me back as she came off the cock for a breath of air, then the cycle repeated. Thrust, moan, withdraw, back thrust, gasp of air, thrust. Another knock on the wall and Dani was dribbling cum down her face as she struggled to keep up with the volume in her mouth. After she swallowed she moaned loudly:
"Mmm. More. MORE!" Another cock came through the wall and Dani again went to work. I had gotten pretty proficient at sister fucking and could stave off my orgasm as long as needed. Three completed cocks became six, then twelve. She was a sweaty mess; she wasn't even a service animal at this point, she was a service machine. Just pleasing men's penises with her body, front and back, like a true slut. God bless her.
I finally relented and filled her pussy full of my cream. After I came in her, she got back on her knees and kept sucking cocks through the wall. A dozen, two dozen. I lost count at 30. She was covered in other men's cum from her face to her pubes, just dripping down her like a river. Still she wanted more, like she needed to suck cock to survive.
I needed to pee so I let her know I was going to the head while she gave it. As I walked to the bathroom, my heart sank. There, at the lockers... were my parents. Mom was in the process of changing her clothes but had not donned her mask yet. I quickly did an about face and went back to the gloryhole room with Dani. She was still sucking cock on her knees. I pulled her off. The guy complained.
"Sorry, she needs a break!" I closed the hole and whispered to her.
"Dani, we are in serious shit."
