She was very flirtatious and while at the mall she talked me into getting some new underwear and it was a sexy as the swimsuit earlier in the day. Sadie was very sassy to people she met when she was out. When we got the panties I of course bought them and the woman asked if they were for a girlfriend? Sadie told her it was for her and she couldn't wait to show them off to her brother and her daddy once she got them home. Needless to say she embarrassed the woman who was simply trying to make a cute comment. The first couple days went by and Sadie and I were fucking and sucking like newlyweds. It was a good thing that she couldn't get pregnant or I would have knocked her up for sure. On Wednesday Mom came to me and asked if I would mind if they took a little vacation. They had not been alone since I left and Dad surprised her with a little cruise to Mexico. She said they could probably get four tickets instead of two if I wanted but the thought of being alone with my new found sex goddess for a week made my cock grow as I talked to my mother on the phone so of course I said yes. When I told Sadie she jumped up and down telling me she loved it. "We can pretend to be married!" she said and I kissed her and she ran upstairs. "Can we sleep in Mommy & Daddy's bed? I nodded and she squealed and ran upstairs. They left on Friday and I took them to the airport with my sister and we were so sweet to them. We assured them that we would be fine and Dad slipped me a couple hundreds and we waved to them as they boarded the plane and once out of site we quickly left the airport and headed to the garage where we parked the SUV. Once inside the truck, Sadie looked at me and said, "OMG big brother we get to spend an entire week with each other alone. I can't wait! Can I suck your cock right here, right now?" Not being one to tell her no I put the console up and she leaned over and unzipped my cock and put it in her mouth. She was getting to be so good she had me cumming in her mouth in less than five minutes. Once she swallowed it all she sat up and wiped her mouth and smacked her lips and said "Ahhhhhhh, that hit the spot Bro." She sat back in her chair and I lowered the console back into position and we buckled up and headed home. First stop was the drug store where I bought three big tubes of KY Jelly. The sales clerk gave me and my sister a funny look as she run it up. Sadie was not one to miss an opportunity to make someone uncomfortable, she put up a compact and acted like she was cleaning something off her lips. We got home and I placed her on top of the kitchen table and I licked her pussy until she came all over the place where the family eats their Sunday dinner. I had her screaming and twisting from side to side as she came and came and came. We proceeded to fuck that night and I used plenty of lubrication as not to make her tiny pink pussy hurt too much. After all if she started to hurt she wouldn't want to have sex. That night we fucked twice in a row on our parent's bed and I ended up cumming all over her and we wiped it up with the pillow my father sleeps on. It was sick and twisted for sure but we were having so much fun. The next day we went to the local water park. She wanted to show off the new swimsuit she got from one of Mariah's friends and it was saucy and sexy. She made sure she showed it off to older men and she was sassy to their wives knowing that their husband was gawking at her and not their fat wife. She met one of her friends from school at the park. Her name was Mimi and she was starting her first year at middle school in the fall. She was gorgeous, she was Asian, very petite maybe 4'10", Sadie said the was 11-years-old and she had sexy little breasts that were captured in a tight little one piece swimsuit that was so tight that when she was wet you could see every outline of her body in the dark blue suit. From her hard little nipples to the curves of her pussy; and if you looked hard enough you could even see the cleft that was where her clitoris hid at the top of her pussy. She was at the park with one of her friend's family and she stayed with us all afternoon. It got to the point where the father of the girl who brought her to the park came over and told her they were leaving and when Mimi said she would get home on her own he made me promise to get her home safe. I agreed and he slipped me a $20 bill and said thanks. Mimi said that he was ogling her the entire time and she was getting creepy feelings from his leering. "You know he was only being human." I said to Mimi as she stared into my eyes like she had a crush on me. I've seen it before. "I mean I was staring at your body all afternoon, it's amazing and that swimsuit is amazing." "Yeah but he's old." She said and she leaned over and whispered to my sister and they giggled and ran off towards the restrooms. They were definitely the hottest girls in the park in my mind. Watching them walk off showed their tight asses off and my cock stirred. Mimi was a full head taller than Sadie but she was just as sexy. They came back and they were chatting. When they got back they stood in front of me letting me look at their sexy little bodies. Sadie got close and whispered to me, "She wants to come to the house!" I looked at her and gave her a cross look and said, "Why?" "She wants me to eat her pussy and she wants to suck you off!" "Sadie we talked about this. You can't tell anyone!" I said. "I didn't she just thinks you are cute and she knows that me and Mariah are doing it. Come on Joey she's cute!" "I know but she needs to keep it quiet! Will she?" "I guess so. Let's pack up and talk in the car." Sadie said loud enough for her friend to hear. "Thanks Joey!" Mimi said looking at me. We got in the SUV and the girls didn't waste any time. Before we got out of the waterpark's parking lot they were in the back seat kissing. Mimi was the more aggressive of the two but Sadie was not stopping her at all. Mimi was leaning over kissing her and I could not see much other than that they were kissing until Mimi put her hand in my baby sister's lap and started playing with her cunt through her bikini. Sadie spread her legs wider and soon her hand was inside her bikini completely rubbing her bald little pussy. Sadie was moaning soon and then before we even got home she came under her ministrations. I was glad the park was not far from the house because I was now hard as a rock and ready to fuck both of these kids. We finally got home and I parked in the garage and closed the door. By the time I got to their door they were both climbing out. I helped them out of the vehicle and both girls gave my hard cock a playful squeeze and a giggle as they moved past me heading inside the house. I followed them enjoying the view of their tight young asses as I followed them inside. When I got into the kitchen and dropped my keys on the counter both girls were already kissing again. This time Sadie was the more aggressive. I moved next to them and Sadie was all over the older girl. I admired her cone shaped breasts and her nipples were hard under the thin material of her swimsuit. I moved behind her and pulled the straps of the one-piece suite over her shoulders. She helped me as she kissed Sadie and then I pulled her top down and then the entire thing dropped past her slender hips and thighs and I saw her beautiful ass naked for the first time. I rubbed her pussy and ass and she moaned as I slid my middle finger between her tight wet pussy lips. Moving behind my baby sister getting her naked was even easier. I simply undid the two knots on her top and the two on her slim hips and the suit just fell off. I rubbed her bald little cunt as I did her friend and she moaned as well enjoying my touching. She continued kissing the Asian doll in front of her and I rubbed her pussy with my fingers gaining momentum as she began to get out of breath. "I want to eat your pussy!" Mimi said to Sadie. Sadie smiled and nodded. The older girl moved her to the floor and placed her on the floor and started licking and sucking her tight, clean snatch. She knelt between her legs and soon Sadie was moaning as she enjoyed the older girl licking her pussy with such expertise. Mimi looked over at me. I was watching her lick Sadie's cunt and admiring the view of her sexy ass in the air in front of me. "Come on Brad! Don't just stand there! Fuck me in the ass!" "My name is Joey not Brad!" I said. She broke away from my 8-year-old sister's willing pussy and replied, "Who cares, just fuck me with that big cock!" she returned to Sadie's pussy and I nodded and placed my cock at the entrance to her asshole. I applied pressure and the head slid in dry. It must have hurt her a little since she grunted as soon as it went inside and I pushed harder and it was about hallway inside her. She turned and looked at me and had an angry look on her face. She was so hot and the inside of her asshole was very moist. I pulled out then shoved it back inside her and she grunted and squealed with the motion. She returned to sucking Sadie's cunt and Sadie watched me as I ass fucked her 11-year-old friend. She closed her eyes and I moved faster and she grunted like an animal as I fucked her. She liked making noise this one. She must watch porn because she sounded just like a porn star as I fucked her little pre-teen asshole. She squealed loud. "Ohhhhh fuck me Joey!" she screamed and I fucked her completely and grabbed her arms out from under her and pulled her up. I held them tight and she closed her eyes and let me use her completely. "Uh, uh, uhhhhhh ah, ah,ah aieeeee!" she groaned. Sadie pulled her face back down enough so she could again suck her pussy. "Lick it while he fucks you!" Once her mouth was on her pussy again she pushed her pussy up higher and ground it in her mouth as she licked her. I held the little girl tight and fucked her insanely tight ass. "Get ready I'm going to cum soon!" I said as I pushed my cock completely into her asshole. She turned her head looking at me and her face was contorted and she breathed heavy. "Ohhhhhh it's soooo gooood!" she growled as I fucked as deep and as hard as I could. "Ahhhhhh fuck! I'm cumming!" I said as I spewed cum inside her hungry ass. I looked down enjoying the vision of my cock punching in and out of her tightly sucking asshole. I shoved it all the way in and felt my cock pulse as it delivered my payload. I released her arms and she fell down with her face again next to Sadie's waiting pussy. She returned to licking my sister's cunt. I pulled out of the tiny girl and leaned back watching her eat her out. In another minute she was licking her pussy madly and Sadie was holding her head as she sucked her preparing to have her own orgasm. When she came she pulled her friends face tightly towards her riding her mouth as she climaxed. She opened her eyes and cooed as Mimi finished her off. When she was finished licking her cunt she climbed up and they kissed a while and then both of them looked at me smiling. "That was fun!" Mimi said squeezing her friend tightly. "But I gotta go! Joey, can you take me home?" "Sure Mimi. Anything for my little China Doll!" I replied. She laughed and came next to me and said, "You're such a tard! I'm Korean not Chinese! But you're a tard with a big cock so that's okay! Right Sadie?" Sadie smiled nodding. "Yep! My big brother has a nice, big cock!" She winked at me and we all dressed and headed into the car. We drove her home and Sadie and I returned home after grabbing some pizza and we ate pizza and fooled around all night. She had been sleeping with me in our Parent's bed. We acted like we owned the place and we were married.
