I stopped down the block from Megan's house. She had convinced her sister that having her picture taken wouldn't be such a bad idea. Lyssa wasn't sure, but agreed to at least give it a shot. I watched as the two girls walked home. I would follow in a few minutes after Megan broke the ice with her dad and gave me a call.

It didn't take her 10 minutes to make that call. I casually drove up to the house and walked up the drive to a run-down looking frame home. Not much to look at in this not-much-to-look-at neighborhood. I knew her dad was now disabled and could not do any of the repairs himself. I almost felt guilty about what I was proposing. Almost.

Megan made the introductions. He was guarded, as I expected him to be. Knowing his oldest daughter had just sucked me to a mind-blowing orgasm less than an hour before was enough to keep a smile on my face as she nervously shifted from one foot to the other while we talked.

"So, you wanna take pictures of my little girls? For what? One of them porn magazines?" he asked with an almost sneer. I thought I could detect the odor of whiskey or some other alcohol, but wasn't sure. The inside of the house was neat, and I suspected that was Megan's doing.

"No sir. I haven't been doing this long, so I don't have a local customer base. I have some clients overseas who want American girls for their ads. I take a few shots of the girls in a casual setting and send them via email.

"If the clients like how the girl looks, they send a request back for specific clothing and poses, sometimes even specific scenes. I have taken some on a boat, by the lake, in a park, and some in front of a green screen so the customer can change the background to suit themselves." I showed him a portfolio I had put together with different girls.

He mulled that over for a few minutes then asked about the money. I told him the same I had told the girls. Like them, he was cautious still.

"And the customers want them to model clothes and such?" he asked in his half-drunken stupor.

"Exactly. I can assure you that I do not take the photos for anyone here in the states."

That seemed to do it. He agreed the girls could model as long as they wanted. I felt my cock starting to grow as they jumped around the room. We set up a time and I agreed to pick them up myself. With sizes of both girls in hand (Megan knew I had to keep up a front), I told them I would meet them the next day. They were to dress in something casual and we would start the day at a local park.

Both girls were dressed in denim shorts and t-shirts. Megan's hair was in a single ponytail and Lyssa wore hers in two braids. They had not worn any make-up as I had told them I wanted a natural look in the beginning.

Lyssa was a little more friendly today, and Megan was obviously trying to keep our secret. I had already masturbated twice the night before and once before I picked them up just thinking about the possibilities that were ahead.

I started by taking several pics of the girls on the swings and other playground equipment. They seemed relaxed in front of the camera and worked well together. As we neared noon, the temperature started rising. We were all starting to sweat a little, I suggested we break for lunch. They agreed and we loaded up in my RV.

After stopping at a pizza joint, they asked where we would do the next shoot. I suggested we go to the mall and finish up in the RV. Lyssa was excited to see what outfits I had chosen for her. Megan gave me a wink and "accidentally" rubbed her bare leg against me several times while we ate.

I parked in a distant corner of the lot and pulled the curtains over the windows. I had left the generator running with the A/C on, so it was very comfortable. Pretending Megan had not been inside before, I showed them where to change. I had laid out a sundress, skirt/top set and a modest bikini for each girl.

"What do you want first?" Lyssa asked. What I really wanted was to strip them both and fuck them until I couldn't walk.

"How about the sundress? I'll do some shots of you individually, then some together. We'll use the green screen I talked about."

I left the room as the girls started to change. Turning on my remote cameras and monitors, I watched little sis as she stripped out of her t-shirt and shorts. As I thought, her breasts were still forming, and weren't much more than fatty tissue topped with light brown nipples. Her panties were white with some type of print on them.

Megan had worn a pale blue bra with matching panties. I almost wished I had told her about the cameras. Maybe she would have posed just for them. Slipping on the sundresses, they checked their hair and started for the door. I turned off my monitors and grabbed my camera.

Lyssa wanted to go first. Big sis watched as I directed her through different poses. When I had her sit on a stool, her legs spread slightly and her white panties were visible. I snapped off a couple before she realized what I was doing.

"Hey! You took pictures of my panties! No fair!" she protested.

"Well, Lyssa, I'll admit it. I did. I'll give you a little advice and you can think about it. Like I told your dad, my customer base is overseas. Most of those customers want to see smooth skin. In the initial shots, they like to see some upskirt shots.

"If you really want to model, you have to decide what you are willing to show." I let her chew on that for a couple of minutes.

"Who are you kidding, Lyssa?" Megan teased her. "I know you like to let the boys in your class see your panties. I dare you to pull off your dress and let him take shots of you in JUST your panties!" I did love it when sisters tease each other. My cock was starting to grow at the thought. I'm sure Megan noticed that too.

"NO WAY! You take your dress off." Lyssa countered.

"Fine! I'll show you!" Megan told her emphatically as she lifted the thin dress over her head. Her panties came into view and I was snapping pics. Flat, smooth tummy. Bra that matched her panties. With a flourish, she tossed the dress to the side and stood there with her hands on her hips.

"There, Miss Smarty. I did it. Now, it's your turn."

For a moment, I thought her younger sister would cry. Sliding off the stool, she stood in front of Megan. Slowly, she reached for the bottom of the dress, then stopped.

"No fair. You have on a bra and I don't."

Megan gave me a sly look then unsnapped her bra and let it fall. "Now, I'm not wearing a bra either. Your turn."

Lyssa stared in shock at her sister's semi-nude body. She had to do it now. The dress came up and off. Two light brown nipples topping two fatty, budding breast mounds came into view. "There! I did it too!"

As I continued snapping the pics, Lyssa upped the odds on big sis. "I dare you to take off your panties, too."

Megan, knowing I had already seen her nude, didn't hesitate. Thumbs hooked in the waistband, eyes on little sis, and the panties came down. As she stepped out of them, she spread her legs slightly, her arms at her sides, palms up as if to say "now what?"

Lyssa's face was bright red. Megan had accepted the dare. A deep breath, and she followed suit. Both girls were totally bald. Lyssa's lips were well formed for her age, although I suspected they would be more defined as she continued to grow. In my mind, they were screaming for me to kiss them. I wanted to do that, and watch as they stretched around my cock. Patience, Rob, patience I had to remind myself.

"Well now, ladies," I began, "this is quite a change. I'm glad no one around here will see these. Your dad couldn't keep the boys away if they became public."

Suddenly, the realization hit Lyssa. She was standing nude in a stranger's RV while he took pictures. A LOT of pictures. She grabbed for her dress to cover up, but Megan was too quick for her.

"Stop Megan! Give it to me!" she cried out. Megan wasn't budging. She knew she had her sister in a vulnerable position now.

"Lyssa," I spoke firmly, but softly. She turned to look at me, still clutching at the dress. "Don't worry. You and Megan both are very beautiful, and have great bodies. I promised not to show the pictures here, and I won't.

"Besides, you have an effect on me that beautiful sexy girls are supposed to have." I placed the camera on the counter and turned to face them. Megan walked over to me, her arms circled my waist and she looked up. The cat was about to be out of the bag now. I pulled her to me and kissed her deeply. I could hear Lyssa gasp in surprise.

Megan turned around after our kiss and looked at her sister. "Here's the deal. I've already let him take some pics before today. Yesterday before we met you, I just gave my first blow-job. He promised to show me some other stuff next time.

"Today is next time. I don't know what you've done sexually, but I want this. I want him to teach me everything he's willing to teach me. And I want you to go along with it. We can make some good money, and maybe get out of that dump we're living in. What do you say sis?"

Lyssa stood there chewing on her lip. "Did you really give him a bj?" Megan decided actions would speak louder than words. She started to unbuckle my belt. I held my arms at my sides and let her.

"I, um, only did it once." Megan looked at her sister in mock surprise. "I was at Jenny's house and her brother was there with some of his friends. We played "seven minutes in heaven" and I went into the closet with him.

"We kissed first, and it just felt so good when he touched me, you know? So when he pulled it out, he said I should suck him off. He squirted on my shirt before I did much more than kiss the tip. I had to change shirts in the closet. I'm just glad me and Jenny wear the same size." She hung her head and looked nervously at her feet.

Megan had my jeans loose and was pushing them down. She turned to her sister as I stepped out of them. I pulled my shirt over my head and stood there in my briefs, my erection clearly visible.

"Her brother is such an idiot. He tried to grab my butt one day in the hall. Just because he's 15 and still in junior high, he thinks all the guys should be afraid of him and all the girls should fall over him. If he was so smart, he would pass and get out of the 8th grade.

"Besides, THIS" as she lowered my briefs and exposed my cock, "is a MAN'S COCK!"

Lyssa's eyes went wide at the boldness of her sister. Evidently, she had assumed Megan was a prude and not interested in boys because of the way she dressed. I had awakened a sexual dynamo. I was ready for the next step.

"Lyssa," I said softly. She looked up at me. "Here's the deal. I told you both before that smooth skin sells. I'm a man who loves to look at sexy girls, too. I like looking at you both. Megan and I did this yesterday like she said. I want to do that and more with both of you. You can stop me at anytime you are uncomfortable with what we're doing. But know this,"

When I hesitated, I knew I had her undivided attention.

"What happens here, stays here. One word leaks out to anyone and the pictures are public. I mean public as in your school's website. I don't like to blackmail, but I will protect myself. Understand?"

"Come on sis," Megan pleaded as her soft hands wrapped around my cock. "I know Mr. Rob will be a lot better than any kid at school. Look at his cock, don't you want to touch it?" She stepped to the side, still stroking. Lyssa looked up at me, then stepped closer. Her smaller hand reached out and covered her sister's. Megan pulled her hand back and covered Lyssa's, jacking the shaft like I had showed her yesterday.

"It's hot, and bigger than Jacky's. Do you squirt a lot?" Megan giggled and answered for me: "A LOT! But I liked it. Let me show you."

She leaned forward and took the mushroom head into her warm mouth. I groaned and she knelt before me. While Lyssa jacked what wasn't going in and out of Megan's mouth, Megan wrapped her arms around my thighs and bobbed her head, taking more in with each suck.

After a few minutes, she pulled Lyssa down to her level. I watched, with camera in hand, as the sisters took turns sucking and licking my cock. I had to do something to take my mind of the incredible sensations, or I would have blown my load very quickly!

"Lyssa, did you taste it when Jacky came? Or did it just get on you?"

"I didn't taste anything. We were trying to hurry 'cuz we knew everyone was on the other side of the door waiting on us to come out."

"Then you need to taste this, sis," Megan told her. I was about to say the same thing, but Megan beat me to it. Lyssa had a doubtful look on her face, but opened her mouth to take my cock in again. As she bobbed her head on my shaft, Megan stood up and kissed me. I cupped her perfect little ass and returned the kiss. All the stimulation was too much.

I squeezed her ass and grunted as the first spurts erupted into Lyssa's mouth. My knees almost buckled as I released Megan's ass and grabbed her head by those two braids pumping several ropes of cum down her throat. She gagged with the first jet, but tried to swallow as much as she could. When her mouth filled, she pulled back and the last couple of streams landed on her chin and breasts.

Megan surprised us both when she leaned over and licked the strands from her sister. Evidently, Lyssa's breasts had not been touched before, so this was definitely another new experience for her. Everything that had happened so far had put her in an emotional overload. By the time she realized what her sis was doing, Megan had fastened her mouth over one of those delicious looking nipples.

"Oohh, sis, what are you, ohhhhhh" she moaned out. I regained my senses fast enough to capture the moment on camera. I knew the video cameras were rolling as well, so what I missed was already there. I let them play for a few more minutes, both girls loving the action.

"Let's go into the other room, girls," I said softly to them. They didn't hesitate when I gently pulled on their shoulders to guide them. Lyssa was still in a semi-shocked state, but followed Megan down the hallway. I moved the other outfits from the bed and pulled back the covers. I had the girls lay side by side on the bed , their legs hanging off the side, and took a couple of shots before leaning over them.

"What now, Mr. Rob?" Lyssa asked.

I set the camera down and moved between Megan's legs. She spread them eagerly for me. My cock was growing, but I wanted to taste her first. I looked at her angelic face, her ponytail was over her head, one hand across her waist, the other had reached for her sister. Lyssa took it and was squeezing it.

"Now, I'm going to do something I wanted to do the first time I saw Megan."

Leaning over, I softly kissed her puffy labia, diving between the lips with my tongue. Megan's pelvis bucked upwards, her legs spread more as she tried to get closer.

"Ohhh, WOW!" her hands were both on my head now as I showed her my version of the joys of oral sex. Seeking her little magic button, my tongue flicked across it before I sucked the protruding flesh into my mouth. It had been a tough decision for me whether to suck those perfect little "A" cups first, or go for her mound. The mound won out.

I spread her lips and stuck my tongue as far inside as I could reach, working the tip in and around her vaginal entrance. My hands went under her hips, squeezing and caressing those tight little ass cheeks. As I worked over her pussy, I felt movement on the bed. I looked up enough to see Lyssa moving over her sister. The girls locked lips in a lustful kiss. Little sister's hands were moving over Megan's breasts, pinching and pulling the eraser-sized nipples.

I could hear her breathing become ragged as she neared orgasm. I worked her harder, pressing a thumb against her tunnel, teasing the passage, letting her know what I wanted. Her juices were free-flowing now, and I was loving the taste of that sweet nectar. Little sis was next, I hoped, as I brought Megan over the edge.

"YESSSSSSSSSSSSSSSSSSSSS!!!!! OHHHHHHHHHHHH!!!!!!!!!!! UNGHHHHHHHHHHHHH!!!!!" she screamed out as the orgasm took her. Lyssa pulled back and watched her sister's body being wracked by the waves of pleasure. She turned to look at me coyly as she lay on her back and spread her well-toned thighs. Resting on her elbows, she hooked a finger in a "come here" motion.

"Can you make me feel like that?" she whispered. What an invitation! Still on my knees, I scooted over a few inches between her knees. I knew what she wanted, and decided to tease her a little. The smell of female juices were in the room. Megan was leaking onto my bed, and Lyssa's lips were obviously already moist when I looked up.

I kissed the sole of her left foot, then worked my way up her leg. As I neared her mound, she took my head in her hands and tried to direct me to her pussy. Not yet. Breathing out softly across the labia, I kissed down her right thigh, all the way down to her toes.

She was squirming as my fingers danced along her smooth skin, followed by my lips. This time, when I reached her labia, I whispered: "spread your lips for me, Lyssa."

Her slender fingers separated those tender lips and my tongue found the spot we both wanted. She came as soon as I licked up her slit, flicking across her button at the top. Little Lyssa was a squirter! The first squirt took me by surprise, but I opened my mouth and drank her juice, finally covering her mound fully with my mouth as my tongue worked over her.

Her little hips were bucking as the pleasure washed over her. I knew I had her now. She would do anything I wanted, and her sister's friend would never be thought of again!

Standing, I wiped my mouth with the back of my hand and looked down. Megan looked at me with lust in her eyes. Lyssa's eyes were still closed as her chest heaved, trying to catch her breath.

"Rob," Megan said softly, "are you gonna fuck me now?" The combination of the whispered question, the profanity from her pretty mouth, and her spread legs, was the stuff of dreams.

I moved back between her legs and leaned over her. My cock was at full strength again, and rubbing across the top of her mound as I kissed my new "model" passionately. Her arms were around my neck, as her tongue explored my mouth, savoring her sister's juices. I moved back and forth, my cock sliding up and down her slit.

I felt her hand move between us and take my cock, guiding it to her waiting tunnel. I pulled back and looked into her soft eyes. "Are you sure, Megan?"

Her response was to lock her legs around my waist and pull. The resistance was there. I pushed forward, she pulled with her legs, arching her hips to meet my thrust. Her maidenhead ripped, she winced, then pulled again. I knew she would be alright.

Lyssa came out of her orgasm-induced stupor and realized her sister was being fucked right next to her. Her eyes grew wide as she watched half of my cock disappear inside her big sis. I withdrew and pushed forward, stretching the tunnel with each thrust.

Megan grunted as her body adjusted to this new experience. I was trying to take it slowly, but the sensations were so incredible, it was very difficult. After a few minutes, I was fully inside. I stopped and looked at her.

"Are you OK, Megan?" as I held myself in place.

She smiled the most beautiful smile I had ever seen as she nodded and arched her pelvis again. It was clear she wanted me to continue. Who was I to deny her? As far as we were concerned, we were alone in the universe. Two bodies had become one and we were connected by my cock.

When I told her I couldn't last much longer, she said she was close again too. I moved faster, sliding out to where just the head was inside before plunging fully inside again. As the cum bubbled from my heavy balls, I pushed as deep as I could and held it. My seed erupted and sprayed directly against her womb, filling it and her pussy for the first time. I was grunting with animalistic pleasure. She was moaning and bucking as her second orgasm washed over her. Remembering Lyssa, I looked over to see her frantically rubbing herself to her own orgasm. Her juices squirted across her legs and my bed as her moans of pleasure joined ours.

In spite of the air conditioning, I was sweating. I pulled out of Megan, our cum stringing from her gaping pussy as I rolled onto the bed next to her.

"OK," she gasped out, "THAT was, wow, oh fuck, oh wow, ohhhhh, " was all she could manage. Lyssa giggled at her as she raised up to look at me.

"So, Mr. Rob, does this mean you're gonna fuck me too?"

All I could do was gasp out a weak "you bet your ass" as the girls started laughing at me. "Just as soon as I catch my breath and get hard again. You bet your ass little girl."
