Desc: Erotica Sex Story: Chapter 1 - He may be very young (16 years of age) but he is a very capable substitute in many situations. His sister Melody and her friend Jane ask him to be their nude photographic model when their original model cancels. They then entice him with their bodies to tell about his other substitutions with - Monica (the neighbour), Cara (his brothers wife), Megan and Sara (lesbian lovers needing sperm), Priya (neglected Indian wife) and Amy (neglected pregnant wife).

I am Adrian, and I am 16 years old. I am the adopted brother of James (23 years old) and Melody 18 years old. My life has changed so much in the last 6 months. This is my story.

"Adrian ... can I ask you for a favour" asked Jane poking her head into my bedroom.

Jane was the 18 year friend of my sister Melody. They had been closeted away in her room all morning - working on a college project they told me.

Jane was a tall slim brunette, standing 5ft 7ins tall. Her hair was cut short but with a fringe that often dangled across her eyes. She had a beautiful face and a lovely smile.

In the last six months I had discovered the mysteries of the female of the species. I had largely ignored them up to the last 6 months, but now I was casting an appreciative eye across all females that I encountered.

Jane stepped into my room. She was wearing tight-fitting white shorts, with a pink top that also clung to her nice tits.

"Tits" was my favourite word - "Breasts" just seemed too correct a term to use when talking about sexy young bodies.

She had very nice legs with my gaze drawn to her bare feet - beautifully formed with bright red toenail paint which matched her fingernails too.

"What can I do to help such a beautiful young lady?" I asked cheekily, flirting with her once again.

"Beautiful ... you think that I'm beautiful?" she asked.

I just smiled back at her, and she laughed nervously back at me.

I waited, and she appeared nervous.

"Well..." I prompted her.

"Adrian..." she started then paused for a moment "Melody and I have an important photographic assignment to do ... and our model just called to cancel".

"Oh" I replied.

"We ... I was wondering if we could ask you to model for us" Jane explained then added "Melody said that you wouldn't be interested".

I was becoming more outgoing, and I thought that this might be my chance to spend some perving time with my sister and her beautiful friend.

I paused for a moment before asking "What do I have to do?"

"Well..." she started nervously again.

Then Jane blurted out "We need our model to pose naked". She looked down to the floor, afraid to make eye contact with me.

"Holy shit" I thought "Did I just get asked to get naked in front of a couple of teenage girls". I was quite proud of my body - I had been working out in the gym often, and had nice body and muscle definition. I'd also been comparing manhoods with other guys in the locker room - catching sly glances, nothing too obvious. I knew that my manhood compared well with the other guys of my age - in fact it was much fatter and longer than theirs ... even when limp.

"Mmmm ... I want to see where this is going to lead" I thought before I responded.

"'Oh..." I started to respond then I asked "Don't I have to be 18 years old to pose like that?"

"Yeh ... but I figured that you look older than you really are ... so we could get away with it".

We discussed things for the next 10 minutes - types of poses, ways of concealing my identity etc, deciding that I could wear an eye mask to add to the mystery of the situation, and to protect my identity from any who chose to tease me.

I decided that I would do it - I had no idea where this situation would lead to.

"Ok ... I'll do it" I told her.

That made her very happy ... she gave me a huge hug, pressing her firm body against mine. I slipped my arms around her and held her against me just that little longer.

'I'll take a shower to get ready" I offered.

"Great ... I'll go and tell Melody ... we need to setup her room".

She then added "I'll leave your costume on your bed whilst you shower". We had discussed a black leather posing costume as part of our discussions.

In the shower I decided to be bold and shave my pubes off completely. I had been trimming them for some time, with my balls kept smoothly devoid of hair. Handling my cock, and thinking of the posing session had my cock on its way to full hardness.

In my bedroom I found my leather costume but had problems working out how to wear it.

"Jane" I called out "Could you help me with this costume?".

I waited and heard some animated discussions going on behind the closed door of my sisters bedroom.

"I can't figure it out" I shouted out in explanation.

Within a couple of minutes Jane returned to my bedroom to find me standing naked facing the doorway with a three-quarter hard cock, and with my hands on my hips.

She was visibly stunned at getting to see me naked a little earlier than expected.

I held up the leather costume which consisted of a number of seemingly random straps.

"How does this fit?" I asked as I walked up to her and handed it to her.

I could see that she was having problems keeping her eyes off my cock, especially when it twitched about of its own accord, hardening even more.

She flipped the leather about a few times before she was happy it was in the right position.

"You need to step into it this way" she explained.

"Hold it for me" I asked as I raised one of my feet off the ground.

Reluctantly she knelt down and held it as I stepped into it. My cock was so close to her face that it brushed against her cheek. She helped me pull up the straps to my thighs. The interesting part was going to be threading my cock through the hole in the groin piece.

"You need to help me with this part" I told her. I could have done it myself but I wanted her to touch and handle my cock.

She spread the hole with her fingers whilst I directed my cock through the gap that she had created with my cock brushing against her fingers.

"Help me get it sitting right" I asked her. "Hold me ... while I adjust it".

I didn't wait for her to think - I grabbed her hand and placed it on my cock. Her hand felt so soft on my hardness.

"Hold it whilst I adjust it" I told her.

Surprisingly she held it, gazing at it from very close quarters whilst I took my time adjusting and readjusting it. I took much longer than necessary since I was enjoying her touches.

"What do you think?" I asked her when I removed my hands.

She was still holding my cock when she responded "It's very beautiful ... and big too".

I nudged forward, bringing my cock into contact with her face again, sliding it along her cheek and down across her closed lips.

"C'mon you guys" yelled out Melody from her room.

The moment was broken by her poorly timed interruption.

Jane stood up, reluctantly releasing my cock, and handing me the face mask that I was going to wear during the photo session.

Melody was more than a little shocked when I strode confidently into her room with my hard cock leading the way.

She is my sister but I have secretly perved on her in recent months with her body developing nicely with large rounded tits sitting proudly on her slim body. Her blonde hair hung just below her shoulder line.

"Oh god" she gasped.

"Where do you want me posing?" I asked as I deliberately walked close to her.

Jane had a smirk on her face, seeing Melody's discomfort.

Jane took over, setting my poses, and taking every opportunity to touch my body, even some sly touches on my hard cock.

Melody settled a little, and was soon taking photos as Jane worked my poses.

After half an hour Jane surprised me when she said "Time for me to join in the posing".

"Oh fuck" I muttered under my breath as Jane quickly disrobed, joining me naked in the centre of the room. She quickly put on a face mask too to hide her identity.

"Jane ... Jane what are you doing? ... We didn't discuss this" Melody said speaking quickly.

"It's fine ... just keep snapping photos" Jane replied.

For the next 15 minutes, Jane found so many different ways to press her naked body against mine. Her tits were firm with nice hard little nipples that grazed my chest and back regularly. Her mound had just a thin landing strip of hair with her large pussy lips completely bare.

I had a couple of favourite poses - one involved my cock pressing against her firm ass with my hands cupping her firm tits, whilst kissing her earlobe. The other was Jane standing behind me with her tits pressed into my back with her hand grasping my cock around the base.

The heat in the posing went up enormously when she knelt in front of me with her hand grasping my cock around its base. She leant forward and positioned my cock near her open mouth. Melody was busy snapping photos when I leant forward sending my cock into her hot mouth.

"Umph..." she moaned with a few inches of cock in her mouth, with her lips wrapped around my shaft.

"Jane ... he's my little brother" gasped Melody who was now kneeling beside Jane watching her suck my cock.

"Mmmmm ... mmmmm" were the noises made by Jane as I pumped my cock in and out of her mouth, with over half my cock sliding in and out. Her oral skills were superb.

"Oh fuck" I shouted with my cock exploding in her mouth, sending a torrent of my hot cum into her throat and mouth. She gulped and swallowed as quick as she could.

"Oh my god ... you're cumming in her mouth" my sister excitedly commented.

When I finished cumming in her mouth, I drew her to her feet, pulling her against me and kissing her, tasting my own cum on her lips. Initially she hesitated, but then became an active participant in the passionate kissing.

I shuffled us backwards until I was able to sit on the edge of the bed, drawing her onto my lap with my still hard cock trapped between us. We continued to kiss. I encouraged her to lift up, giving me the chance to grasp my cock and position it between her very wet pussy lips.

Melody was behind us snapping photos of my cockhead sitting between her parted pussy lips.

I slowly eased her down onto my shaft - its thickness parting the tight entrance to her pussy coal, and slipping into her hot tight sheath.

"Oh fuck" grunted Jane.

'He's fucking you" screamed Melody.

'Oh my god ... oh fuck ... oh fuck ... so big" moaned Jane as she fucked up and down on my hard thick shaft.

I placed my hands around her waist linking together behind her back, allowing her to lean back. The change of angle sent my cock all the way into her pussy, with her ample pussy lips gripping the base of my shaft.

Her firm tits stood out proudly from her chest, attracting initially my gaze and then my lips and tongue. I flicked the nipples with my tongue before taking them between my lips to suck them one after the other.

I could feel her pussy juices flooding my shaft just before she orgasmed, grabbing my cock firmly with her pussy muscles during the period of her cum explosion. That set me off - I exploded inside her, filling her pussy with another load of my white creamy cum.

"Yes ... oh yessssssssss!!!" she screamed "I can feel your cum squirting inside me".

Her hips were churning rapidly against mine, with the excess of our juices streaming out from between us, running down my balls.

Melody had placed the camera on the floor, and was sitting back on the floor with one hand in her panties with the other hand clutching at her tits. She was working herself towards an orgasm.

Jane threw her arms around my neck as she plunged up and down on my still hard shaft.

"Fuck me ... fuck me ... so fucking good ... so big ... I feel so full" she gasped racing towards another massive cum.

I was surprised that I had another cum building so soon after my last one. When she exploded, she tipped me over the edge too. I erupted inside her, adding to my precious cum load in the depths of her snapping pussy.

Fifteen minutes later I was still laying naked on the bed with Jane in my arms and Melody sitting on the end of the bed.

Jane spoke 'You have done that before ... haven't you?"

I just smiled and did not respond.

Both Jane and Melody were persistent ... with them eventually extracting the stories that are contained in the following chapters.
