Chapter 1

Stephen slowly crept across the hallway and stood outside her room. He had woken up late and wasn't sure if she was still home. His sister Shelly had been left in charge whilst their parents were away. Shelly was 22 and four years older than Stephen. She was a very popular girl and always had lots of boyfriends. Stephen knew exactly why, she had massive tits. These tits were the source of admiration for Stpehen. He dreamed about them all the time and would give anything to be able to see them. He was 18 and had never had a girlfriend, the only girl he ever fantasised about was his sister. He'd been planing his next move all weekend. It was the summer holidays, and his parents were away on holiday. As they left they'd told Shelly she was in charge and should look after her brother. This caused Stephen alot of annoyance as he didn't think he needed looking after and Shelly was always teasing him as it was anyway. Today was his chance to get one up on her though.

He stood outside her room, being as quiet as he could, his ear pressed to the door listening to see if she was in. After two minutes he decided to risk it and opened the door. He walked into the room and saw it was empty. Shelly must have gone round to her boyfriend's house for the day. He could have his fun without being interupted. He looked round and wondered where he should start. Then he spied a pair of her panties on the bed, she must have slept in these last night he thought. He walked over to them and picked them up, he held them to his nose and inhaled, there was a strong musky smell that filled his nostrells. He looked at the soft white cotton and noticed that it was stained, he held them out and licked at the crotch where the stain was, believing he was tasting his sister. A tent instantly grew inside his shorts and visions of his sister whirled round inside his head. He knew he had to be patient though as he wanted as much fun as possible. He pulled his shorts down and stood inside her room naked, his dick pointing up swaying infront of him. He rubbed the crotch of the panties against the head of his dick and began laughing out loud. He'd waited so long to be able to do this and he knew that whenever he saw his sister, he'd always know what he'd done in her room and she wouldn't. Her teasing wouldn't bother him any more.

What next he thought to himself? He threw her panties back on the bed and walked over to her dresser, pulling onen the top drawer he peered inside, it was full of all her underwear. I ran his hands over them, feeling the differnce in the textures of the materials, some soft, some smooth some silky. He truely was in heaven. He picked up one of her bra's and looked at the label, 38EE. He always imagined she was a D cup, but EE was even better. He ran his tounge all over the inside of the soft satin cup, knowing that her nipples will be touching it next, his mind rationalising that he would therefore be licking her nipples. He picked up a black frilly thong out of the drawer and held it up. It was made of barely any material.

"Fuck me, she'd look so hot in this" he said out loud to himself. "I wish I could see her in it"

Then a thought popped into his head. She had a full length mirror in the room. He stepped into the thong and pulled it up and walked over to the mirror and turned round looking at his arse, knowing that what he saw would be what he could see if she was wearing them. He bent over at the waist imagining that it was her. He spend the next 5 minutes doing this with many of her thongs and panties. What next he thought, he wanted more, he craved more.

He looked in her wardrobe and wanted to pick out some of her most slutty clothes. He found a black mini skirt that he knew she hadn't worn for a year or two as it was now too small. Being only slight he knew he could still wear it. He chose his favorite thong of hers, put it on them stepped into the mini skirt and pulled it up. Walking over to the mirror he bent over and saw how it lifted to reveal the thong and arse cheeks. He knew this is what she must have done in the past. He was so horny at this point, but he wanted more, before he'd allow himself to release. He went over and picked up a bra, he put his arms through it and tried to fasten it, but he couldn't manage it. He figured out though that if he put it around him backwords, he could do up the clasp them move it round and feed his arms through it. He walked over to the mirror, but it didn't look right. The big cups were empty, he needed to stuff them. He then spied her laundry basket at the end of the room. He walked over, noticing the nice sensation from the silky thong as he walked, and opened the basket. He picked up her dirties, smelliest panties and stuffed them into the bra, to give himself some fat tits like his sister.
