Katie
Jack was staying with his friend Dee. During dinner some unexpected guests arrived - Dee's parents and her eldest niece, Katie.
Jack couldn't help noticing that Katie was growing up fast. Her hips had filled out slightly. More noticeable though was her cleavage which had filled out in a delicious way. Jack thought that her chest must be at least a C cup, which looked fantastic on her slim 18 year old body. Her washboard stomach was on view, peeping from under a cropped top she was wearing.
Dee's parents explained that Katie had wanted to come and stay with Dee that night before they all went to visit more relatives the day after. Dee said "well we have a house full now, but we'll find somewhere for Katie to sleep." With that Dee's parents departed.
Katie sat down at the dinner table opposite Jack and smiled at him. "When I heard you were going to be here Jack I thought you could tell me more about growing up with Auntie."
"Yes, I can tell you about how we used to play with each other." Katie's cheeks reddened as she remembered asking that question of Dee and Jack innocently the year before.
"You blush most beautifully Katie," said Jack. "In fact you're turning into a beautiful girl." Katie blushed again but suddenly realised that she wanted to be with Jack alone. Her aunt had described how she and Jack used to talk and touch each other when they were alone.
The evening passed quickly as the wine flowed; Dee allowed Katie to have two glasses as well. Katie felt very relaxed and did not notice that her top had slipped a little revealing her black bra strap.
Jack however did notice and couldn't help imagining running his fingers over the black satin, as he used to with Dee. He had learnt with Dee how to make foreplay into an event in itself.
He was imagining having the same fun with Katie. Unknown to him Katie had exactly the same thoughts.
She was curious about her body and how it would react in a sexual encounter.
Making coffee in the kitchen Katie asked Dee about growing up. Dee told her that Jack used to turn her on with his gentle touches all over her body.
"He used to drive me crazy because he never touched my nipples and even when he used to rub my feet and thighs he never touched my panties."
Katie started to wonder if she could somehow learn firsthand from Jack.
As they started to think about going to bed Dee said "Katie, you'll have to sleep on the couch because the children are already in bed and Jack has the spare room." Katie suddenly remembered the mattress under the bed in the spare room and said "There is that mattress under the spare bed. If we drag it out I can sleep on that".
Dee said "Yes, now where should we put it?"
Katie said "Why not just leave it at the foot of the spare bed. I promise not to disturb Jack; I'm a very quiet sleeper."
Dee was doubtful about whether this was proper but Katie said "I'll stay dressed because I'm leaving early tomorrow anyway". At this Dee relented, mainly because she was tired but also because she trusted Jack, even though her husband was away on business.
"OK just this once. Soon we'll get another bed for the spare bedroom."
Jack had been in the en suite bathroom so had not heard any of this exchange. As he came out Of the bathroom wearing only his boxer shorts he found Katie crawling under the bed to pull out a mattress from underneath. He stood for a second admiring her pert backside. "Katie what are you doing in here?" he asked.
"Dee said I should get this mattress out and sleep on it tonight. She said it would be OK to sleep on the floor in here. Do you mind?" Katie asked with a shy smile.
Jack shook his head as rude thoughts started to run through his mind. He moved quickly to get into bed so Katie wouldn't see his cock growing inside his boxers.
Katie went to the bathroom and Jack heard her flushing the toilet. She came out into the bedroom and asked to borrow some toothpaste. Jack said "sure" while trying not to stare at her beautiful breasts.
"OK" said Katie and wandered back into the bathroom. Jack noticed that she hadn't bothered refastening the button of her jeans and from what he could see she appeared be wearing a black satin thong. "I'd love to see more of that" he thought.
Katie came out from the bathroom and leaned over Jack to kiss him goodnight. She smelled of mint and went to kiss Jack on the cheek, but he turned his face just as she leant towards him, so she ended up kissing his lips.
She pulled away amazed by the electric feeling that ran through her body. She leaned over again and kissed him.
Jack said "Katie, what are you doing?" Katie replied "Auntie told me that you used to kiss her and touch her when you were growing up. I wanted to learn about boys from someone older and I thought you could teach me about things. After all she trusts you so I think I can too."
Jack started to wonder how this night was going to turn out, but said to Katie "If you want I could touch you like I used to touch her, but you must not tell her. If you turn the main light out I'll put the side lamp on and you can snuggle up in my bed; rather than sleeping on the floor".
With that Katie walked over to the door, turned off the light and turned back to face Jack. "How do you want me?" she asked suggestively.
"Well I think maybe you'll be more comfortable without your jeans on." he replied, with a cheeky grin.
Katie looked unsure, as she thought how revealing her skimpy black panties were. Eventually curiosity overcame her and she unzipped her jeans and slid them down. Jack's cock got harder still as she stood up straight and he saw the outline of her mound for the first time.
