Erin gawped!
you couldn’t describe it any other way! Like a cartoon character confronted by something they could comprehend, she stood in the doorway with her mouth open and her eyes wide, almost popping from her head.

Only a minute earlier she had arrived home from school, an afternoon of playing rounders on the field under the hottest sun of the summer had worn her out. Letting herself in without her usual burst of 11 year old energy, she had dropped her school bag in the hall and wearily climbed the stairs intending to shower and change (she avoided showers at school because unlike most of her school friends Erin had developed boobs when she was 10 and she felt embarressed by their prominence)

but now! …….

as she had passed the small “box” room, the door was half open and it was only then she realised she wasnt the only person home. Her mums boyfriend Mark was there, not only was he there but Erin realised with shock he was naked! For a reason unknown Erin involuntarily took a step forward into the doorway itself, thats when she began to gawp. Mark wasnt just naked Erin could now see he was holding someing in one hand , moving the hand up and down slowly but rythymically.

*oh my god* Erin suddenly realised *He’s rubbing his cock!*

At the realisation Erin felt a shiver of fear run through her, and quickly stepped back into the relative safety of the darker hallway. She knew she should go to her room, or downstairs or somewhere and she knew what Mark was doing was something she wasnt meant to see but …….. she continued to stare. He had his headphones on so perhaps he wouldnt hear he if she kept really really quiet?

…………………

Mark heard the click of the key in the door and knew the moment to put his plan into operation had arrived. Operation Erin he called it, a plan to seduce Claire’s 11 year old daughter., not that Claire had any idea about his plans, he had been very careful in choosing a woman with a girl the right age and Erin was ideal. They had been dating about 4 months before Marks overnight stays became weekends then a week here and there, withing 6 months he had moved his things in and began living with Claire and Erin , happy families! Claire was a good if fairly routine fuck. 33 years old and she had begun visiting the gym just before Mark met her so she was getting her body into a decent shape, She sucked and fucked whenever he moved on her and he had taught her that anal sex could be fun (she had never let a man do that before) it brought them closer.

Quickly he threw off his bathroobe so he was totally nude, placed a set of headphones over his ears (no sound coming from them but it was an idea he had that perhaps thinking he couldnt hear her Erin might not be too concerned.) He angled the chair so that his hard cock was clearly visible from the doorway, and almost hidden by the side of him was a small mirror directed towards the doorway so he could watch and see if Erin looked and how she reacted.

His cock was already hard, he had spent last several hours chatting with a group of friends he had on-line. All of them very much into young girls, they chatted and shared whatever images they had come across in there endless quest for kiddy porn. Now and then somebody would have a Eureka moment and discover a video clip. They were always the best and Mark masturbated often to the collection he had gathered, always dreaming of Erin and teaching her to do the things the girls in the videos did so willingly.

A sound made him flick his eyes to the mirror, was she out there? was that a movement? YES! The movement turned very suddenly into a clear image of Erin stood in the doorway staring at Marks cock as he slowly stroked himself. His heart suddenly began to pound in his chest, what would she do? Almost as suddenly as she had appeared she disappeared and Mark almost let out an audible groan of disappointment!

*Fuck* he thought *shes gone!*

wait! No ………. no… she wasnt gone! Mark looking at the small mirror (wishing it were bigger!) saw another movement and then realised Erin had backed into the hall but was still watching him!

his hand went to the base of his cock, exposing its full length to the little girls view. He knew his cock was just average sized. Even now when it felt as big and hard as he had ever know it, he was no longer than 6.5 inches it was however thick with a large bulbous head that his lack of foreskin allowed to show fully. The knowledge that 7 or 8 feet away a preteen girl was watching HIS cock made it throb and jump with excitement and as he he held the pose a large ooze of precum escaped the piss slit and slowly began to trickle down his glans. Without thinking Mark reached uo with a finger and thumb, capturing the precum and brought it to his mouth where he licked the sweet liquid with an audible slurp and moan! He knew if he just speeded up his stroking he would be quirting his cum in seconds, Mark knew after watching all his other pedo friends wanking on their webcams that he was what was known as a heavy cummer. It seemed he could produce perhaps twice as much cum as any of the others, and not just now and then but pretty much all the time (even Claire had commented on it when she sucked his cock and swallowed his spunk the first time “I thought I was going to drown”!)

Erin held her breath, she couldnt bring herself to tear herself away from the scene in front of her. The shiver she of fear she felt had passed and she realised then combined with the fear was a sense of excitement, almost anticipation. If she could keep quiet perhaps Mark wouldn’t know she was there and she could keep watching him? The very idea made her blush! She watched Mark hold his cock at the bottom so it stood up in the air, he moved a little and Erin saw it was almost as though it was pointing at her! Well at least in her direction. She thought Marks cock was huge, and as this was the first cock she had ever seen hard she had nothing to compare it to.
