Today I heard Evie and Amber discussing the Halloween costume party that they were going to on Friday night. Evie was going as the genie from the "I Dream of Genie" TV show, and Amber was going as Elvira. (She certainly had the body for it and the long black hair) They were still talking about it when I stepped into the room carrying my own costume. "Hi Evie..."

"It's EVA!"

"Yeah, whatever, anyway, as I was saying, hi Evie and hellllooo sexy Amber..."

"Dale, I've told you before, STOP!" Evie said as Amber smiled at me and blushed.

"Shit, can a guy never finish a thought around you? So you gals are going to a party too."

"You're going to a different one right, my DEAR brother," Evie snarled at me, emphasizing the word 'dear'.

"I don't know, which party are you going to?"

Amber quickly said, "The one at Phi Jama Jama fraternity!" Then quickly got a glare from my sister and she shut her mouth tightly.

I could tell my sister was pisssssssed off so I quickly said, "Hey, guess it's your lucky weekend, sis, I'm going to one over at Randy's parents' house! Too bad as I know how much you like it when I show up where you are." I easily ducked her punch and swatted her ass before stepping back and saying, "Look, I've even got my costume ready, I'm going as the cowboy Hop-A-long Cassidy."

Evie turned up her nose in disgust saying, "Very um, original, Tex," then both of them broke out in raucous laughter. I left them alone and was soon finding out everything I could about Phi Jama Jama fraternity. Then I called around town and found a costume place with a Spiderman costume in my size that came as a top, bottom and head covering. For what I had planned I didn't want to be in a complete body suit!

Friday came and Amber and Evie were getting ready for their party. I noticed that Evie had a jacket in her room and it wasn't really cold out, hmmmmm. After donning my cowboy outfit I knocked on her door as I turned the knob and pushed it open. Evie jumped as she applied her makeup, putting a big streak of blue shit on her cheek. What I really noticed was that THIS Genie had a fairly easy to see through top and when she jumped her luscious boobs bounced nicely making her bright pink nipples move all about under the shear fabric.

"Damn sis, even YOU look sexy tonight!" I said as she glared at me and tried to cover her chest. "Too late, sis, all ready saw them both! They're nearly as nice as Amber's are!" Amber smiled and blushed again. "You two make me wish I hadn't volunteered to help with the party at Randy's place! I'd love to be there at Fly Yama Bama tonight! Oh well, have fun and watch out for spooky monsters! Elvira, you look soooooooo hot!"

I checked my reflection in the mirror and then left with him bidding me a hearty "Good luck!" I drove around for awhile and went to the drive up at Burger King for a Whopper and a Coke. No way did I want to get there on an empty stomach and get drunk from one drink! Finally about 9:15 I parked down the street from the frat house and donned my tight fitting hood mask, then walked up to the door with a group of about seven other people in costumes. The guy at the door looked us over and said hi to the ones whose identity he could discern, then let us all in. He never gave me a second look as I was the tallest of the group.

Nearly instantly somebody handed me a beer and a topless girl ran up and gave me a tongue filled kiss! She broke the kiss and said, "Hi Spiderman, I'm Eve! I lost my Adam, will you take his place?"

I looked her over quickly and said, "Maybe later Eve, but right now I'm trying to find somebody. Nice tits though," I said as I boldly reached out and pinched her right tit.

She reached out and stroked my limp dick and gasped when she watched it grow down my leg. "WOW Spidy, if you don't find her, you come find me, please?!"

After nearly an hour I thought I had finally found Amber's Elvira only to discover the girl was supposed to be Lilly Munster! She didn't let that deter her as she kissed me hard and ground our bodies together for a long time. When she finally broke our embrace she reached down and ran her fingers the entire length of my dick and asked, "Is this all you? It's not nice to fool with Lilly," my cock head twitched as she slid her fingers around my tip and she groaned out "Ooooo, it IS real! Come find me when you are done with Elvira!"

Surprisingly, I bumped into Amber as she stumbled around wanting to know who was looking for her. She gave me a once over and then dropped her liquid impaired eyes to my crotch again and said "Just who is this gorgeous Spiderman that is looking for me?" I deepened my voice trying to keep her from recognizing me and we chatted briefly as we tried to dance. Finally she ground her mound against my third leg and said, "Oh god, come with me. I have got to try some of your huge cock!"

As quickly as she could due to her tipsy status, she turned around and leaned in to kiss me while once more guiding my cock to her fuck hole. "Like this, Spiderman? You want to watch me fuck your huge cock?"

"Oh yeahhhhh," I groaned as she sank down onto me. I was in heaven but also thought Evie had glanced my way briefly. It wasn't until her fourth full thrust down that I realized I had spoke in my normal voice, shit! My sister was back at her blowjob on her guy as he sucked her pussy and Amber was in another universe as my cock gave her pleasure she apparently had never known existed before. Her voice started out in soft, quiet tones a she cried out "Oh my god, you are so BIG! Nobody has ever been so deep in me before ... Oh god ... oh GOD ... Oh shit I'M CUMMING ALREADY!" and she was screaming in pleasure as she rode me to her first climax. My hands were squeezing her gorgeous tits and then I leaned up and began sucking on one hard nipple then the other as her climaxes rolled on and on. By the time Amber was crying out in the midst of her third orgasm, practically every one of the girls were looking over at me wondering why it wasn't them that was happily fucking herself on my cock. The guys got pissed and soon the room was nearly empty. Only Evie and her guy remained along with two couples who were out cold, having passed out in the middle of their fuck. Evie had moved on top of her guy and was trying to ride his cock but I could tell she wasn't getting any pleasure from her efforts. In reality, she was watching her best friend bouncing on my shaft as orgasm after orgasm racked her beautiful body.

Suddenly Amber tensed as my cock grew even bigger inside her and she screamed out, "OH YES! OH FUCK, SPIDERMAN, GIVE IT TO ME, GIVE ME YOUR CUM! OH FUCK ME AND FILL ME WITH YOUR CUM!" She was rocking her pussy on me, her opening tightly attached to me as if we were one body. My balls erupted into her, blasting torrents of cum against her cervix as she screamed in climax once again! Amber arched her back and her head fell back letting her long hair tickle my legs as she shivered in ecstasy as wave after glorious wave of bliss washed over her.

As Amber shook hard above me she soon lost the ability to speak in any language, her sounds having no meaning at all. Still her body was forcing her pussy harder and harder onto me as her climax pounded her body into submission! Finally she slowed her movements and straightened her body. Her eyes came back into focus and she looked down at me with her face aglow with love and lust quite briefly before she keeled over and passed out, exhausted from our lovemaking and her thunderous climaxes.

Amber slowly dropped between my body and that of my sister's fuck mate and she breathed deeply with a contented smile on her face. Making certain to keep my voice deep I said, "Hey, Amber, are you alright?" I was getting worried when my sister reached over and gently put her hand on my arm.

Again I moved as if to leave and she jumped up and straddled me then dropped her pussy right onto me, not stopping until she had over half of my cock up her velvet tunnel. "Oh fuckkkkkkkk that's so good! Oh PLEASE don't leave yet! Please fuck me with your wonderful cock, PLEASE!" All the while she begged me her pussy was pumping on and off of me, slowly working more of me in until she sat there with about seven inches stuffed inside of her. "Please, let me fuck you and then after I climax I'll suck you off and swallow your cum...oh god PLEASE!"

In my deep voice I slowly said, "Well, you do feel really nice like this. And you can suck cock extremely well. Okay, you're on!"

Boy was she! Evie was pounding her hips onto me over and over as her tunnel opened fully and took me to her deepest realms, my cock head bruising her cervix as she slammed onto me in a frenetic pace. I watched her face contort as several small climaxes hit her, then she scrunched up her face in pleasure and screamed "OH MY GODDDD I'M CUMMMMING! I'M CUMMING SO FUCKING HARD! OH GOD YESSSSSSSSSSSSSSSSSS, yes, yes, yes, yes, FUCKKKKKKKKKK!" My sister kept bouncing wildly on my shaft as her groans went on and on until finally her body began to slow and her head slumped down against her chest.

I lifted her head up and said deeply, "Don't even think about passing out on me! You've got a cock to suck and a gallon of cum to swallow!"

Evie looked down at me and a big grin swept her face before she softly said, "I thought you would never ask!" Slowly she pulled her well fucked pussy from me and knelt between my legs. Then she looked into my eyes as she slowly took my cock into her mouth and all the way to the base in one continuous movement. God but I groaned when she did that! "Oh, do you like that, S-man?" I guessed that saying Spiderman would take her too long so she had shortened it up a bit, not that I minded. Instead I just nodded my head and she happily resumed her oral work.

I decided to let her have my load (I had been holding it back just to torment her) and she felt it as my cock swelled even more between her lips and she groaned around me "Ummm hmmm. Ummm hmmm!" I grabbed her head and held her nose to my pubic hair as my first four blasts of cum rocketed straight into her stomach. Then I pushed her head back about six inches and held her there as the remaining five huge ropes of cum filled her mouth to over flowing time and time again. Evie's eyes bulged out as she desperately worked at swallowing everything I had to give her and I gave her a lot!

I released her face and she gently worked her tongue and lips round and round my cock head making certain that she had fully drained me. "Holy shit," she said finally pulling her well stretched mouth from my cock, "you really did have a gallon of cum in these things!" She squeezed my balls lightly as she said that.

Deeply my voice said, "That was really nice, slut, but now look what you've done!" She looked at my cock in surprise wondering what she had done wrong and I continued. "Just how the hell am I to get this back into my pants? Now I need to fuck you once again!"

I pulled her down onto her back next to Amber and took position with my cock just at the entrance to her pussy. "Well, bitch, what do you want me to do?" I huskily asked.
