Christine was the first to arrive at the party. I opened the door, “happy late birthday” Christine yelled. She grabbed me and gave me a kiss on the cheek. She smelled wonderful. She stepped back and I took a quick glance at her. Christine had a short jean skirt on, a pair of black flip-flops, and a black halter top, which showed a lot of cleavage. “Mom and Dad are in back” I said, already hard. “Thanks, hon” she responded. She walked past me and I followed her to the backyard, staring at her tight ass the whole time.

Â

We got to the backyard and my parents said their hellos. “Where is Dale”, Christine’s husband, my dad asked. “Oh, he had to rush out of state for a business emergency” Christine told us, “perfect” I thought in my head. I looked over at mom, she had a pair of tight jeans, and a light blue halter top on. “Shit” I thought, “Mom looks kind of sluty tonight. “Can I get you some beer to drink” I asked. “Sure” everyone responded. I poured everyone one a cup of beer and poured water into mine. I walked back and handed everyone their drinks, “Let’s have a chugging contest” Mom suggested. We chugged, filled up again and chugged once more.

Â

A couple hours later we ate dinner with all the other guests. My sister came down wearing a see-through pair of shorts, an bright orange bikini, and a pair of white flip-flops. Denise had came back from a friends house and had been drinking in the afternoon. I decided to get her really drunk and see her get in trouble. I got my mom, Denise, Christine, and a few other people to take shots. I had 2 while the others slammed down one after the other.

Â

It was around 11:30 and Denise could hardly stand. That’s when Denise walked up to one of our drunk neighbors and kissed him on the mouth, with lots of tongue. Dad grabbed her and told me to take her to her room. I grabbed Denise by the arm and dragged her up the stairs to her room. Denise grabbed me and gave me a kiss on the lips. I pulled away quickly, “Sis, that isn’t funny” I said. Denise tried to take her shirt off but ended up falling on the floor and passing out.

Â

I walked back downstairs to see Christine drinking rum out of a bottle outside. I was going to walk outside and bring her into the house when I heard “Happy Birthday”. I turned to face Mom. “Thanks Mom” I said. “I’ve been waiting for years for this day” Mom said, “I can’t believe it, let’s fuck, now” Mom yelled. She stumbled over to me and fell into my arms, she started to laugh. She regained her balance and untied her halter top in front of the window. My jaw dropped as her massive tits flopped out in front of me. Her boobs were tan and had a small pointed nipples and looked perfect. Mom rubbed her hand on my hard cock through my shorts. I grabbed Mom’s hand and took her to my room. I ripped my clothes off and flicked and sucked on my mother’s hard nipples. Mom moaned as I pinched her other nipple with my hand. I laid Mom down on the bed and pulled her tight jeans off her tan body. I threw her sky blue panties onto the floor and started lapping at my mother’s cunt. Mom shrieked as I rubbed her clit. I slipped a finger in her cunt and Mom gasped. In one swift motion I grabbed my cock and slammed it in my Mom’s sloppy pussy. I grabbed my mother’s tits ands squeezed them together. Mom was screaming as my balls slapped against her ass. Mom’s cunt squeezed tight as she started to cum. It was so tight that I could hardly even cum inside her. I rolled out of her pussy and laid next to her. Mom was still gasping when I played with her tits. Mom fell asleep and I got out of bed.

Â

I grabbed my shirt and shorts when I heard a scream from downstairs. I tiptoed down the stairs to see Christine grabbing the edge of the kitchen counter tightly. Her pants were off and she was screaming as someone licking her cunt. The person then stood up, it was Dad! My dad had his cock out and was slapping Christine’s ass with it. It was huge, probably 10 inches and pretty wide. “Ready bitch” Dad yelled as he positioned to himself to shove his cock up her ass. “Fuck me” Christine screamed wildly. I looked threw the window to see that about 15 people were still outside and could easily see through the glass door to see them fucking. Dad then slammed his hole cock into her ass in one thrust. Christine’s scream was so loud, that my ears started to ring. Dad realizing that someone was going to run into the house, picked up Christine, cock still in her ass, and carried her to the bathroom. I sprinted downstairs. The door slammed shut. A woman ran in, “what happened” she asked, “Christine just fell, she is all right, just a little drunk ya know” I said. “Lets go back outside my Dad’s taking care of her” I offered. We went back outside. I wondered how Dad had kept her quiet. I waited outside a couple of minutes before I went back inside. The bathroom door was open, nobody inside it. I went upstairs and checked all the rooms, no one. I opened the basement door to her the screams of Christine. I closed the door and crept down the stairs. I peeked around the corner to see Christine jumping on Dad’s cock, getting ass fucked. I was jerking my cock harder then ever, seeing her plump breasts bounce all over. Dad then stood up with Christine still on his cock and was thrusting into Christine while standing. Christine juices were flowing like a river down my Dad’s legs. Christine let out an ear splitting scream as Dad shot his load deep into her ass. Dad threw Christine onto the couch and laid next to her. They kissed for a long time until they were both asleep.

Â

I came all over the stairs as this took place. I walked upstairs and noticed that everyone had left. I went upstairs and went to my parent’s bedroom and went to sleep.   Â

Â

I woke up early the next morning and checked on my family. I made some food and watched some television for a little while. I heard Denise come down the stairs. She had the same clothes on as last night. She grabbed a plate of food and sat down next to me. “So, how was last night” Denise asked putting her plate down on the table. “Not bad, you probably wouldn’t remember” I laughed. “I remember little bro. We were right about here”. Denise pulled her top off over her head. I gazed at her large nipples. “Let’s finish what we started” Denise said slipping her tongue down my throat. Denise pulled my shorts down and started sucking my hard cock. Her tongue swirled around my cock and up and down, “I always knew you were a dirty slut” I said. Denise took my cock and slipped it between her two globes. In minutes I came on my sister’s hot tits.

Â

“I have something important to show you” I said grabbing my sister’s hand. We went up to my room were I showed my sister are whore of a mother. “Does Dad know about this” Denise asked. I laughed and showed her Christine and Dad. We went upstairs to our parents room and I ate my sister’s cunt out. Right as we finished we heard our front door close. We ran to the window to see Christine get in her car and drive away. “We are going to have some fun with that little slut” Denise laughed.

Once we got home from shopping I called some friends to come over and Elise left to her boyfriend’s and wouldn’t be back till about 1 in the morning. I went upstairs after Elise left and searched in her drawers. I found that she had huge D-cups compared to my b’s and some more sexy thongs. I decided to borrow one and wear it that night.

Later that night my 3 friends Sarah, (blonde hair tiny breasts and ass) Lindsey,(brown hair, a little heavier but huge breasts) and Jessie (my best friend, brown hair, small breasts like mine) came over first. We only talked for about 5 minutes when my boyfriend Matt, Sarah’s boyfriend Tony, and Jessie’s crush Greg came over. Matt brought vodka and beer over and started watching a movie. We didn’t have to worry since my parents were on a cruise for another week and Elise never comes home early, or even at all.

After the movie all 3 of the guys were totally drunk and so was Jessie. Jessie got up off the couch and told Tony to come upstairs with her. It was around midnight Sarah had to go home and she took Tony with her. Once Sarah and Tony left Matt started making out with me with lots of tongue, the way I like it. A couple minutes later I remembered that Lindsey was sitting right next to us and pulled Matt off “sorry Lindsey” I said. “Ohhh she can just get in the action with us” Matt said, he leaned in and stuck his tongue straight into her mouth. Lindsey knew this was going to be one of her only chances with Matt and she took it. They swapped spit for about 5 minutes before I pulled Lindsey away and started making out with her. Her tongue was flipping in and out of my mouth, for not having a boyfriend she was turning me on. Suddenly I heard my sister’s voice yell “what the hell” from upstairs. Lindsey and I got up and ran upstairs from the basement. Elise was standing with her arms folded. “What are they doing” Elise pointed at the kitchen table. Jessie and Greg were both completely naked and fucking on the kitchen table. “Jessie, stop” I screamed Jessie tried getting up and putting on her clothes but she was to drunk to even stand. “Were you guys drinking” Elise shouted. “Yes, please don’t tell mom and dad” I begged as I tried helping Jessie up. Elise saw I was sincere about this “ok” she said “but we’re taking everybody home now”

Everyone climbed into are parents van, Jessie sitting in front with my sister knowing that she and Greg would try screwing if they sat together. We dropped everyone off and headed home. I noticed Elise’s hair was a little messy and her tank-top fell off her shoulder and her bra was missing from before she left. “What did you do tonight” I asked. “Nothing” she said. We sat in silence for a little while. “What’s it like you have sex” I said as we pulled into the driveway. Elise turned around “what makes you think I know” she asked. “You were at a party tonight, you drank, and your bras missing” I said looking at her half naked breast. She pulled up her top and we walked into the house. “You really want to know” she said and walked up the stairs. “Yes” I begged and followed her up to her room. Elise opened the closet and pulled out a shoe box and opened it. Inside where a 10-inch vibrator, and a 10-inch strap-on. “You sure you want to know” She turned around and asked. I knew what she meant and said “yeah”. She pulled out the strap-on and pulled off her white top. Her breasts were so big and her tits were brown like mine and completely stiff also like mine. She walked over in her tight jeans and pulled off my shirt. Then she pulled off my bra and squeezed my tits together. We kissed a couple of times until she bent down and sucked on my tits. Matt had done this several times but nothing like my sister was doing. She bit on my tits a little and unbuttoned my jeans and pulled them down, “is this mine” she asked. I looked to see the dark blue thong I borrowed earlier. I nodded, Elise smiled and pulled my jeans off. She stood back up and pushed me onto her bed. Elise pulled down her tight jeans, she had a sexy light green and shiny g-string. She then stepped into the strap-on and got on top of me. “Suck” she demanded. I stuck the cock in my mouth and sucked it like Matt’s cock. I grabbed her hips and sucked long and deep mouthfuls. “You’re good at his and she slightly swung her hips. After the cock was well lubricated Elise turned me around and got me in doggy style position. She pulled off the thong and she started to rub my clit. I was already soaked. Elise realized this and stuck one finger into my cunt. I moaned loudly, she then put in another one and started to fuck me with her pink painted fingernails. When she put in a third finger I thought I was going to go crazy. Elise thought I was ready and stuck the dildo into my pussy. I was being stretched and I yelled “fuck yeah keep on going”. She kept on going and broke my hymen.  “Virgin, just the way I like em” she said and started to rub my thighs. Elise got seven inches in and started to pump. I let out loud screams after every thrust. We banged for awhile until I came off the first time. I collapsed on the bed Elise pulled off her strap-on and thong. I returned the favor and licked her shaven cunt. Elise loved in and gave out similar yelling shrieks. Liquids filled my mouth as my big sis came in mouth. Minutes later Elise and I fell asleep together in her room.
