The next morning, Marie-Louise and Julia went to church, leaving me home alone. I put on a pair of track suit pants and went into the kitchen to make myself a cup of coffee. While the kettle was boiling, I strolled through the small two bedroom town house and quickly found myself in Julia's room. It was a mess with clothes and toys all over the place. I bent down to pick up a pair of her panties and brought them to my nose. Hidden beneath the faint odour of urine, I found of a hint of Julia's female scent. I could feel myself getting hard, and saw the huge bulge in my pants, reflected in Julia's mirror. I dropped the track suit pants down to my knees, and saw the reflection of my erect cock in the mirror. I rubbed the groin area of her panties between my thumb and fore finger in an attempt to revive the aroma, I'm not sure if it was my imagination, but I was sure that I could smell her young pussy. My cock was rock-hard and, in the reflection of the mirror, it seemed very big against my flat stomach.

I grabbed the base of my cock and with a firm grip, began to stroke the length of my shaft. When I reached the tip of my cock, I clamped the pink head in the palm of my hand and massaged it my rapidly, squeezing and relaxing my grip. I kicked my track suit pants to the side so I was completely naked, and began looking for another pair of her panties with hopefully, more of her hidden secrets.

Naked, I walked to the bathroom and searched through the laundry for another pair of panties. I found her heavy blue school uniform ones. In the crotch area, I saw very faint traces of a crusted fluid, and a stronger scent of her young genitals. While holding her panties close to my nose, I jerked my cock for three or four powerful strokes before I spotted a pair of Marie-Louise's panties. I recognised the g-string that she had worn the previous day, the pair in which she'd given me her masturbation show. I saw similar remnants of crusted fluid in the crotch area and immediately knew that it was a mixture of her juices and my semen.The thought drove me wild... could Julia be sexually active?

I continued stroking my cock and felt my orgasm building,the pleasure generated by my hand washing through my entire body. I dropped the panties, and used my left hand to massage my balls and dropped to my knees on top of the dirty laundry as I brought myself to a climax. My white semen launched from the tip of cock, soiling the garments below.

I had just finished placing the washing back in the basket when I heard Marie-Louise and Julia at the front door. Quickly, I went back into Julia's room to put my track suit pants back on, and I met them in the living room, trying to act nonchalant. My hard-on had not completely subsided yet, and it was evident in my bulging track suit pants. Marie-Louise seemed pleased, and leaned in for a sensual kiss, her groin rubbing up on mine, her intentions clear.

"Are you going to do sex again?" was Julia's snooty comment.

Marie-Louise's hand moved down and massaged my semi-flaccid cock over my pants.

"Get a room!" was Julia's humorous response.

Marie-Louise took me by the hand, and lead me into her bedroom. She kissed me again and started pushing my track suit pants down. The events of the morning left me wanting more. She pushed me onto the bed and pulled my track suit pants down over my ankles, and started sucking me. There were some residue semen in my shaft and my recent orgasm made my best effort an semi erect penis. Marie-Louise loved sucking my cock after sex, and knew the signs. She milked the remaining cum from my cock and asked in a seductive voice "Did we play with our cock while the girls were in church? What did you think about hmm playing with the girls? Hmm...I bet you would have liked that?"

The next Sunday evening I stayed over again. Julia and I went to get DVD's and pizza, and when we got back, Julia went for a bath. When she finished, we settled in front of the TV. Julia was wearing her pyjamas. The pants were well worn, and fitted a little too snug. She clearly wasn't wearing panties, making them very revealing. I could clearly see the outline of her cunt lips. I focused less on the movie and more on Julia's groin, slowly getting very aroused. She was laying on a mattress below the couch I was laying on, on her back with her legs slightly spread apart. From my vantage point I could see her skinny legs, oversized knees, and wide gap at the top. Her protruding pubic bone accented the split in the middle, her light green pyjama bottoms fitted like a second skin, almost as if she was naked with light green skin. I could not take my eyes off of her cunt.

Marie-Louise found the movie Julia selected boring and went to bed. I covered myself with a blanket and pulled my track suit pants down to just below my hips. Under the blanket, with my eyes fixed on Julia's two little cunt lips, I massaged the tip of my erect cock. I could feel the lust building in me, overwhelming me, and I imagined her rubbing her naked little cunt on my leg. I imagined what her face would look like if she "got the feeling" as Marie-Louise so eloquently put it. I imagined her naked little butt and the tiny butt hole. What it would smell like? Taste like? Look like?

I don't know what made Julia turn around to look at me, I was in fantasy land, but when I opened my eyes, she was looking right at me. I was still masturbating and when I noticed her looking at me, I had no idea what to expect.

"Are playing with you pee pee?" she whispered, as if she knew it was a secret.

She stretched her neck and almost deliberately looked down at my groin. I pulled the blanket to the side, exposing my erect cock. I could see her swallow hard before she whispered again.

"Is it big... just like daddy's?"

She extended her hand and touched it. She was fascinated by my erect cock, and in the light of the flickering TV, I could see her hand pulling away from the tip of my cock, as long, thin, spider-web like strands of pre-cum briefly hung in the air between my cock and her hand. As she pulled her hand towards her, she felt the stickiness on her fingers, and wiped it on her pyjama top. I opened my legs, and she slid in between them, sitting on her knees in front of me. She wasn't jerking my cock, but her hands slid up and down my shaft as she explored it.

She then leant in and kissed the tip of my cock with tight lips, before she briefly stuck out her tongue and licked it. Looking pleased with herself, she sat back. Then, as if instructed by a inaudible voice, she laid back, pulling her green pants down over her ankles. She then laid on her back on the mattress with her legs open, inviting me to explore.

I hopped off the sofa with my track suit now around my knees, and took up a position beside her with my erect cock exposed. I slipped a finger in between her lips and searched for wetness which to my surprise, I found. Her young hairless cunt was wet. With the moisture on my finger I tried to find her clit, the only evidence being a very small bump where her clit must be. I moved around and laid on my stomach between her legs to lick her. I could smell the faint aroma of urine, overwhelming the even fainter smell of cunt and wet vagina. I licked her all the way from the opening of her vagina to her clit. When I pulled her lips apart, I could see her clit, which was no bigger that the tip of a big pen. As I licked her, her hips began to move rhythmically, so she was definitely getting the feeling.

I guided her over onto her stomach, and then I pulled her bum cheeks apart to see the small pink hole for the first time. It smells like ass, the rich, warm, unmistakable smell of dirty sex. I lick her bum hole as the hip motions continue. She seemed to like it. I turned her around and lifted her knees to my chest, pushing them together and guiding my cock into the tight space created by her inner thighs pushing together, to fuck her young body.

I looked at her, and noticed her pyjama top had ridden up, exposing the two boyishly flat nipples. I reached out to touch them and as I did, I exploded, my cum shooting through the gap in her legs, partially on her chest and partly on the pyjama top. Her fingers found the sticky cum on her chest and she wiped it off with her green pyjama bottoms. She turned around and continued watching the movie as I pulled my pants up and collapsed on the couch.

"Pull your pants up!"

It is not a question and she did as I told her. We finished watching the movie and then went to bed.

I never talked about it to anyone before!
