It was the end of Alison's week-long stay before she headed back to school the next week. Most aunts would do something like go shopping or and out to a fancy dinner. Well I did take her shopping earlier in the week but not for a fancy dinner but to attend a sex party! My friend Jess and her husband Frank are open swingers who often host adult masquerade parties. They were vital in getting my husband to unknowingly watch me cheat at what was supposed to be a more tame event. Now they enthusiastically agreed to have my niece as part of the entertainment at the next.
We arrived a few hours early, so Alison could get comfortable before getting ready for the event. Jess, Frank, and I reminded her and made sure she was still willing to do what was planned and that she could go by a different name like how I want by Kara. She was to be blindfolded and a number of men unknown to her would fuck her as any of the guest who wished to watch and would not be told who or how many, even after. Alison unhesitatingly agreed, deciding to be called Violet for the evening. With that, Frank left us to get ready. I was in an emerald green backless silk gown that hung off my shoulders with matching heels and lips. The dress did a great job at highlighting my tits and figure. My blonde hair was in an elegant updo with two strands framing my face. Jess was in a fire red and white dress that touched the floor with a plunging neckline all the way to just above her navel that barely covered her C cup breast, white heels, and glossy red lips, with a high ponytail. Alison wore a shimmering sheer black dress with an asymmetrical sparkling silver spider’s web pattern that started from her right breast, fanning out to a floor length hem. The custom-made dress was fitted for her earlier that week and displayed her perfect tits and followed her every curve, hiding nothing. She matched her heels and lips to the purple of her hair that was worn down over her shoulders. Finally, we all put on our masks, they all cover the top of our faces down to the nose, Mine emerald with feathers, Jess’s red with horns and Alison was black with silver matching her dress.
The three of us joined the now arriving guest for drinks and socializing. I introduced my niece to those who I knew, as she drew a lot of attention, being a good deal younger than most there and extremely attractive to all. Alison We were talking with Jess and Frank who my niece seemed really into when I was approached by a large built black make that I immediately recognized despite his mask from past parties. Without saying a word between us, I excused myself from the group and followed the masked man to a semi secluded area.
Still, without saying anything, he undid his pants, pulling out a massive cock. I dropped to my knees and took him as deep as I could in one go. Feeling him stiffening in my mouth, I slowly enjoyed working the length of his shaft, licking at the head. He grunted groans of pleasure were all words I would get out of him, even after he pulled me up and against the wall facing it. Carefully, I lifted my dress for him, presenting him with my tiny green thong. He pulled it down to my knees before pressing his cock into my pussy. I did nothing to hide my moans at the feel of his cock stretching my already wet cunt. "Fuck” I muttered as he slowly slid in and out, making sure to use the entire length. It was nearly 20min he slowly fucked me having my back to the wall for the last bit before flooding me with his cum. No words were spoken as I looked down at my silver watch and left to clean up my makeup. It was nearly time for the performance.
I guided my niece to a room off the main. It had a large circular bed in the middle with red sheets draped over it and other assorted furniture around.
She was shaking from what she said was a mix of nerves and excitement. With a kiss, I slid the blindfold under her mask and secured it in place. Once it was done, Jess rang a small bell letting the others know it was time to enter.
The room was nearly full, with the majority of guests standing or sitting waiting for it to begin. With everyone situated, five men of various ethnicity entered wearing only simple black masks, all very well hung. I unzipped Alison's dress, letting it hit the floor, leaving her naked except her jeweled buttplug. Looking over the audience, I said, “Well boys, she is all yours”. And took a seat next between Jess and Frank.
The five men were gentle at first, kissing her lips, neck, breast, and thighs. Their hands ran over every inch of her young, soft body. Her hands found a pair of cocks and began to stroke them. A devilish smile appeared on her face at the realization of their size. There was no rush, the men enjoyed her body while she stroked whatever cock her hands found. Eventually they lay her on the bed, letting her continue to work the two cocks in hand while the third and fourth took turns sliding in her mouth. The fifth took her pussy. Her moans echoed in the room, causing quiet approval from those watching, myself included. The more Alison got into it, the more assertive the men became. Never rough or aggressive, especially for how she has been fucked before, but the men were fully in control. They all took turns using her mouth and pussy or getting stroked, often they would push on her plug, but that hole was off limits to them. She was on her back then, doggie, followed by being on her side. At times, she was pulled on top and made to ride one of the cocks. The mass of cocks had Alison changing positions almost as much as they changed spots. Her sounds were intoxicating. I couldn't help from rubbing my own pussy and breast watching, and I was far from alone. Many of the other guest men and women play with themselves or others while enjoying the show. I watched her be used for nearly 2 hours when the men started to finish all on her tits, face, and stomach making a show to cover her. During the last 30min or so I had pulled out Frank's cock, stroking him, much to the delight of his wife. Slow, purposeful strokes meant to harden him and lube his cock for what I planned next.
