I sauntered over and got behind Darlene. Like I said, her ass was always a turn on for me. I climbed on the bed and knelt behind her. As my sister looked up from between the model's legs, I rubbed my cock all over Darlene's pussylips. Then in an instant I slipped inside that very wet hole. Now I've fucked Darlene plenty of times in the past but she was a woman possessed this time. Erotic photography always turned her on and often we ended our sessions having sex. But this time she was hotter and wetter than I ever felt her before. And as my dick soon found it's way all the way in, I almost jumped off of her with a sudden surprising touch of my sister's tongue.
Christie's tongue found my swinging balls and boy could she lick them with such skill. I was so horny from enjoying a pleasure that I had never experienced before. I started to fuck my favorite model hard while enjoying my sister's oral ministrations. She pushed back her ass and was mumbling with a face full of Christie's pussy. My balls kept slapping her pussy and a tongue and it felt oh so heavenly. My sister kept busy now as she teased Darlene's pussy and the shaft of my cock with constant wet strokes. I was glad I came not too long ago for I knew I wouldn't have lasted this long if I hadn't.
I grabbed my camera off the bed and began taking closeups of my cock sliding into that hot pussy. My sister's face would appear in between thrusts and I tried to get a shot or two of that as well. But it is extremely difficult to snap photos when you are fucking a cunt like hell. Because Darlene was so wet my cock slipped out of her quim and just that quickly Christie sucked it into her mouth. That sudden change threw me over the edge. I came right down my sister's throat! As I watched between Darlene's asscheeks, my sister gulped and swallowed all of my cum. Darlene brought my sister off and she came as well when that mouth that was on my cock slipped off of me and returned to her aching pussy. I continued watching my sister's tongue tickling her clitoris thoughout Darlene's orgasm.
Darlene and I collapsed on the bed while my sister rolled out from underneath of us both. Then I watched as Christie laid on top of Darlene and they shared my cum in a very sensual kiss. I weakly grabbed my camera and took one last picture of the two of them smiling at the camera with streaky cum all over their lips and faces. I knew these photos would make for some great viewing. Oh yeah, I guess my mug of coffee got cold sitting on the table...
My sister returned to the kitchen after she was dressed. Darlene sat with me still nude as we discussed today's shoot.
"I need some money, Mike. You have nothing in your frig and I need some clothes. I'll go shopping and give you two a break. Darlene, I had a great time with you. I know the brother-sister thing is taboo, but I love that sexy man next to you."
"Yep, he is a wonderful guy. I've been trying to get him to notice me in a more loving manner the past few years but I sensed it was someone else that he loved. I guess it was you."
I handed my sister my wallet and my car keys and she headed out the door. Needless to say the photo work today was much more stimulating. For the first time it turned from eroticism to pornographic. Darlene wore that schoolgirl outfit with my urging and she ventured to finger herself repeatedly and spread herself wide open for the camera while masterbating for me. When we were done, she encouraged me to talk to Christie and thought maybe I should expand my photography to actual sex. She thought my sister would make a good model and could make money that way.
Soon she was gone as she had another appointment that day. I was to have another session with another model but she wasn't feeling well and we postponed it to another day. So while my sister was out I developed the photos and I couldn't wait to show them to Christie.
When my sister returned, she had made sure we wouldn't want for food. I never ate much being by myself, but as we carried the bags in she told me that this wasn't a free ride living off of her brother. She planned to be the perfect housewife. When I looked at her kind of funny, she just kissed me and then giggled as she bustled about the kitchen.
I never realized how good a cook she was. She had placed candles on the table and made it look really romantic. She made a casserole that she told me mom had taught her how to make years ago. We sat together at the table and she would put a fork to my mouth and shared her meal like lovers do. She would also tease me by lifting her top and licking her nipple casing me to almost spit out my food.
When we were done she cleaned up and then took my hand and we went for a walk around the neighborhood as dusk was settling in. We walked hand in hand and we talked about the time we were apart. We came upon a park and sat on a bench in the moonlight and kissed.
Holding my hand she said, "I have never felt so alive as when I'm with you. Growing up, I would dress just for you. I went out on dates but deep down I couldn't wait to come back home and be with you. Remember those late night card games or us sitting and watching a movie together to the wee hours of the morning?"
"I do, sis. I was always worried about you being out with other guys. I couldn't go to sleep until I knew you were home. The time we spent together went by too quickly."
"When I saw you at mom's yesterday, I told myself I would never let you go this time. I am sure I could have found some living arrangements somewhere else but I wanted to be with you. I know being brother and sister that we could never marry, but if I could, I'd want you to be my husband."
"It's funny how life can change in an instant," I told her. "I was alone and even though I had all of these lovely women around for my work, nobody seemed the right fit for me. You are the right fit."
My sister saw a swing set in the moonlight and turned to me and whispered, "Come fuck me on that swing. Let's live out all those fantasies we ever dreamed about."
I looked around but we were alone. As my sister raced to the swings her sexy ass wiggled in those tight jeans. She was trying to pull them off as she was running and I laughed so hard because I thought she'd fall flat on her face. As I joined her she was sitting on the swing just wearing a t-shirt and socks. Her jeans and panties as well as her shoes were strewn all over the place.
I walked up to her and pushed the swing. As it moved back and forth she opened her legs for me and giggled. It was a bright moonlit night and her pussy looked so inviting while I watched her as her legs would part each time she swung towards me. I unzipped my pants and pulled them and my boxers to my ankles. I caught her in the swing as she smiled at me with her arms and legs wide open to me.
I reached for her pussy and felt that she was soaked. As she leaned over to kiss me I guided my cock to her pussy. Her tongue snaked into my mouth and my cock slid easily into her. I grabbed the chains that held the swing and began to move her back and forth onto my cock.
She pulled away from me breathlessly saying, "Your cock belongs inside of me, Mike. I need sex alot and I need you to never stop giving it to me. Please fuck me...ahhhhhhh yes."
So there we were, out there where if anybody walked by we'd be seen having sex for all the world see. The thrill of being out in the open like that had Christie coming often. She'd moan and tell me she was coming, and then we'd start again and she would nibble my neck as she hugged me close. There in the moonlight with a slight breeze blowing against my ass, I came inside of her. I could feel my spurts as they filled her hot pussy. After we both came, we just hugged and kissed like that with me gently pushing her in the swing. Then we heard a noise and we quickly got dressed and ran out of the park. It was probably an animal, but at that moment I felt like we were acting like teeneagers and being very naughty.
We walked home together and she kept kidding me that her panties were filled with my cum. She told me that maybe she'd never wash them again and I just swatted her butt. As we made it back home, we showered together for the first time. I loved washing her hair and soaping up those sexy tits of hers. She made a production out of washing my cock and bent down several times to kiss it and told me she was just checking if she cleaned it good enough to pass inspection. I did the same with her pussy and then we dried each other off.
Then we headed to my bedroom naked. That's when she told me we would be sharing it from now on. And before we went to sleep we made love once again, her on top this time. All was right with the world tonight...
