For the next few months Jess and Bruce "dated" or more accurately hung around together. He seemed more interested in his friends than her, except he would often ask to see her nude. Jess quickly realized he just wanted to see her body and refused each time he asked. The "thrill" of pulling her pants down in front of him just wasn't there any more. The "romance" had run its course.

Tanya announced that she was going to a party with her boyfriend, who was 16 years old, and offered to set up Jess with a date too. Being only 13 she was still not allowed to date according to her parents but arrangements were made for Jess to stay at Tanya's house for the night. Tanya's parents thought the party was going to be an all girl party anyway so none would be the wiser.

On Friday afternoon Jess gathered up her things, grabbed a dress, and rushed over to Tanya's. The girls spent the afternoon doing each other's hair and such getting ready for the party. As soon as the evening meal was over both girls rushed into Tanya's room to change. The door was hardly closed before jeans and tee shirts were in a heap on the floor and both girls were down to their underwear.

The past few months had been kind to Jess. Her once little bumps on her chest had grown to almost an A cup. As she had predicted, the hair on her pussy had remained light but was now visible although still not very thick or course. Unfortunately she still only had her full print briefs. Her mother still wouldn't get her bikini panties. Tanya, on the other hand, had already graduated into thongs.

"I can't believe it! Your mother lets you wear thongs and my mother won't even get me bikinis yet!" Jess complained.

Tanya laughed as she walked to her bureau. "Here. Wear these," she said as she tossed something to Jess.

Jess caught the garment and uncrumpled it. It was one of Tanya's thongs. "Yeah, like it's going to fit me!" she mumbled.

"It will, dummy. Just try it on. You'll see," Tanya admonished. Jess couldn't picture herself wearing the same size clothes as Tanya because Tanya was so much bigger than she was but she dropped her briefs to the floor anyway. She pulled on the thong. "See? Told you they'd fit. Go look in the mirror," Tanya suggested.

Jess walked over to the mirror. From the front the thong looked almost like a bikini with string sides. She turned and looked at the back. A smile came across her face. The back strap went neatly between her ass cheeks framing the roundness of her ass. It surprised her the back strap wasn't uncomfortable. She could feel it but it felt nothing like when her briefs rode onto her ass crack. "They fit great!" she giggled. Not only had they fit well, they also made her feel great. She was no longer wearing "little girl" panties.

The girls quickly finished dressing. Jess felt sexy knowing her ass was bare under her dress. Tanya's mother drove them to the party and dropped them off. A few of the other girls were already there but the boys hadn't arrived yet. Tanya introduced Jess and the group went into the cellar where the party would be held.

Jess was impressed with the house. The basement was completely finished. Jill, the girl whose house it was, explained that the large room they were in would be the main party room. There was a large area for dancing and a few chairs in another part of the room. In a corner was a table set up with chips and other snacks and a refrigerator loaded with soda. "This is the fun room," Jill grinned as she opened a door and the girls looked in.

The room was smaller than the main room and completely dark except for a blue light on the ceiling. It was bright enough to see what was in the room but that was about it. A large TV was on one end of the room but it wasn't on. Along the other three walls were couches. Scattered around the floor were an assortment of large pillows and bean bag chairs. "This is the make out room," Jill grinned. "The only rule is you can't come in to watch; you gotta be playing."

The doorbell rang and Jill ran to answer it leaving the girls. "I plan on spending some time in there," Tanya whispered. Before Jess could comment more girls came downstairs.

"Where's the guys?" one of the girls asked. A knock on the cellar door was the answer. Someone opened the door and a few boys came in. Immediately they were greeted by some of the girls and they soon paired off. Quickly the room filled with girls coming down from upstairs and boys coming in through the cellar door.

Jess looked around in amazement. The room was now filled with teens. She quickly realized she was probably the youngest there. "If anyone asks, I'm almost 15, OK?" Jess whispered to Tanya.

"Whatever," Tanya answered. "I wonder where Ted is." Ted was Tanya's boyfriend. It seemed like Tanya and Jess were the only two single girls in attendance then.

The lights suddenly dimmed and Jess looked around to see why. All around her there were people dancing, talking, and eating. She saw a couple, led by the girl, go into the make out room. Within seconds, a few others went in also. Jess realized she was now standing alone and Tanya was nowhere in sight.

"This is Jack," Jess heard Tanya say from behind her. She turned to see Ted, Tanya, and a boy who was apparently Jack.

"Hi," he greeted. "About time I actually met you. Tanya's shown me pictures of you. You're better in person." Jess could only blush at his compliment. Soon, however, the four were chatting like old friends. Jack really seemed impressed with Jess; almost as much as she was with him. "Wanna dance?" Jack asked. Jess nodded.

They walked onto the dance area and her arms went around his neck. His arms went around her. "How old are you anyway?" he asked.

"Almost 15," she lied. "I know I look younger though. Most people think I'm about 13 or something."

Jack accepted the lie and they began to dance. The music was slow and Jess liked the feeling of his body against hers. After a minute or two his hands slid down from her waist to her ass. Her first reaction was to stop him but she decided against it fearing it would make her appear young. Once she had gotten over the initial shock, his hands on her ass felt nice. Unlike Bruce, it was nice to be held by a boy. At the end of the dance he leaned down and kissed her.

They danced a few more times. Jack's hands went from resting on her ass to slowly rubbing it but Jess didn't seem to mind. Their kissing also increased until, by the last dance, they kissed almost all the way through it. As they walked off the dance floor, they saw Ted and Tanya go into the make out room. "Wanna join them?" Jack asked.

"OK," Jess gushed. Jack took her hand and led her into the room.

The room was dark but Jess could still see the people. Everyone was kissing. A few were sitting on the couches and some were lying on the floor. One couple was prone. The girl was on top of the boy. Her skirt was pulled up to her waist and the boy was rubbing her panty covered ass. She was grinding against him as they kissed.

Jack sat on one of the couches. There was another couple sitting on the other end so Jess sat on his lap. Immediately they began to kiss. The room was quiet save an occasional whisper or a soft groan. Being in the "make out room" with a boy excited Jess.

Jess was leaning into Jack as they kissed when she felt his hand on the back of her leg. It made her a little nervous but she decided to let it be. A few moments later the hand began to creep up the back of her thigh. She grabbed his hand stopping it from going up further. "Not here," she whispered.

"Why not? Look around," Jack protested.

Jess glanced around the room. The girl who was on top of the boy now had her panties pushed down far enough to expose her ass and the boy was now rubbing skin. Another girl was rubbing her boyfriend�s crotch. Jess then saw Tanya and Ted. Tanya's blouse was pulled out of her skirt and Ted's hand was under it. Almost reluctantly Jess released Jack's hand.

Jack�s hand, now free of Jess�s grasp, began to move again. Jess held her breath as the hand crept up the back of her leg. As frightening as the situation was, it was also just as exciting. A boy wanted to touch her body. It wasn�t like Bruce, who seemed to just want to look and study any girl�s body; Jack seemed to be interested in HER body.

�Mmmm� I love a girl who wears a thong,� Jack murmured as his hand cupped Jess�s ass cheek.

�Thanks,� Jess gushed. Suddenly her inhibitions seemed to melt away. She wasn�t just �a little 13 year old� but rather a mature teen. It felt exciting to have Jack�s hand rubbing the bare skin of her ass. A shiver went up her back as his finger traced the material of her thong down between her ass crack. Afraid he would attempt to do more, she shifted some to put that area out of his reach.

Jack made no apparent protest. His finger left her crack, tracing the band up to her waist. Jess let out a little sigh of relief. Jack�s finger continued tracing the waistband of Jess�s thong. It left her ass and rounded her hips, following the material. Jess almost purred until she realized he was heading toward her pussy.

Jess sucked her breath in as Jack�s finger slowly slid down her belly. Another surprise came to Jess as Jack�s finger slid under the edge of her panties. He was now heading toward her pussy from under the thong. She wanted to stop him but hesitated after her last protest had been made to look foolish. A boy had already pushed one of the girl�s panties completely off her ass; how could Jess stop Jack from touching her under her skirt?

�You shave too� Sexy!� Jack whispered as his finger grazed across her mound.

�Yeah,� Jess lied, not wanting to realize she hadn�t really started to grow much hair yet.

Her legs were clamped shut. Having his finger wander around her lower belly and mound seemed daring enough and she was afraid of what else might happen. Jack's finger had left its spot under her panties and his hand was now rubbing what it could reach. Her initial fright was now subsiding and being replaced by arousal. They began kissing again. She could feel his erection against her leg. It felt bigger than Bruce�s. She wondered what he looked like. It pleased her to know he was hard because of her.
