I always came home from clubbing horny wanting to wank but this time was different. Tonight I had been showing my sister around the new town I'd moved too after buying my first flat and taken her clubbing with me. It was 3:30 am and we were in my lounge both pissed and just about ready for bed. I looked at my sister Lisa as she spoke to me. She was 23 with fake blonde hair and a size 12. She was wearing a sexy plain black strappy top which showed off her 34b tits without being too tarty, a short white skirt with one of those big silver belts that's the fashion at the moment topped off with knee eye black leather boots. It was then that I realised she would be the subject off my wanking tonight and not the whores from the club.
"So are you getting me water of what?" Lisa asked bringing me out of my trance. "Sure" I replied and when to the kitchen.
"Your computer is still on, I'll turn it off for you. I know how noisy these can be and as your sleeping in here tonight I don't want to being kept awake." I didn't that any notice as I was busy recalling how long it had been since I had wanked off to here. Must have been 4 years I finally decided. I picked up the water and moved back into the lounge to be met my Lisa watching one of my porn downloads on real player.
"I thought I'd see what music you had on here but when I opened it this started" Lisa reached out and took the water off me" "It looks much more interesting, What's CFNM mean?" She turned to look at me again. On the screen was indeed a CFNM video- it was called "caught in the sunroof".
"Erm... It means Clothed Female nude male, it's mostly around women taking advantage of naked men."
"Sounds like fun" she said with a giggle. We drank the water and watched the four parts to the video as the man testing the car with his wife is caught ogling the sales ladies cleavage and ends up caught in the sun roof and being wanked and humiliated by his wife and the saleslady and finally a passer by. It rains on him and he's called a pervert and eventually cums over the steering wheel.
"That was awesome. It looks so much fun and such a turn on." Lisa said with a big smile. "You got more?" I managed to nod. "Show me your favourite". I gulped as I realised my favourites all involved sisters and mums wanking their brother or son off often together.
"MY favourite isn't in video form. Only pictures I'm afraid."
"Well show me then bro" she insisted. I opened the PowerPoint document I kept it in and clicked start slideshow.
She laughed when the first slide came up and read the title out loud.
"Caught sniffing panties, ha, men are such perverts. The one on the left looks a bit like me don't you think?" She did indeed, the next slide was the scenario about how the two girl flat mates returned home to catch their landlord sniffing one of their pair of knickers (the one who looked like Lisa as it happened), and threaten to tell the police until they realise they can have their wicked way with him. Lisa laughed as she read out select phrases ""Yeah you fucking pervert, what are those? Are those my fucking panties?" You can start by stripping off you sick fuck, The landlord was our bitch!" "This stuffs great" Lisa exclaimed. She watched as one of the girls wanked him off into her knickers before they made him wear them and wrote the website name on his chest in lipstick.
"So you're really into this stuff hey, any thing like this ever happen to you?" she asked.
"Only in my head"
"My landlord's a women so can't see it happening to me soon." She laughed.
Before I had the chance to stop myself I was already speaking the dangerous words.
"It's probably the beer talking but I was planning on wanking off once you'd gone to bed." I paused for breath and Lisa turned to look at me eyebrows raised.
"Go on, I'm listening."
"Well, obviously you wouldn't have to.... You know.... Cos that would be wrong... but I was...."
"Get on with it Gary" Lisa said her arms and legs were folded as she looked at me.
"We could role-play a CFNM scenario... me and you.... You said yourself your landlords a woman so you'd be unlikely to have a go and that it looked fun." She gave nothing a way with her face and she looked at me for what felt an age. She turned and glanced at the screen at the guy wearing the spunky knickers and girls laughing at him. She returned to look at me.
"The knickers I wore on the long sweaty train ride here are in my black bag in the end pocket. Perhaps you want to go check my room is ok and I'll be up in a minute." She looked my hard in the eyes. I couldn't say anything and walked up stairs. In her bag I found the knickers. My heart was racing. They were black satin affect bikini style and indeed they were hot and sweaty. I picked them up and brought them to my nose and inhaled deeply. He smell was heavenly and my cock instantly started straining against my trousers. The door flew open
"What the fuck do you think you're doing?! Are those my knickers? Have I just caught my big brother sniffing my dirty knickers?" Lisa finished her tirade with her hands on her hips looking very cross. I just blinked at her, her knickers still at my nose.
"Well start explaining then bro". That confirmed it, we weren't role-playing landlord and tenant this was brother and sister.
I lowered the knickers and looked at the floor as I bashfully tried to explain myself.
"I was just doing some washing and was seeing what I could wash for you."
"Bollocks, its 4 in the morning, you thought you'd sneak in here and get your jollies with my knickers whilst I was in the bathroom didn't you. You were probably going to sneak them to your room and sniff them whilst you mastibated weren't you? Well there is no chance of that now" she stormed across the room and snatched the knickers off me. "I'm calling our parents to tell them what a pervert you are."
I looked up at her.
"You can't do that, they'll disown me, please don't. I'm sorry I'll make it up to you."
"Really and how do you propose to do that you sicko?"
My mind was racing, I really couldn't tell if this was role-play or if she'd been testing me and was actually shocked that I'd taken the trick bait.
"I'll do anything you want, lend you money, my car whatever."
"You'd lend me your car? Hmmm" Lisa knew how much my car meant to me, "You must be desperate to keep this between ourselves mustn't you, you little pervert. Lets see how desperate shall we. Take off you clothes."
I looked at her and she raised her knickers again so I could see them. I nodded and slowly stripped to my boxer shorts and Lisa twirled her knickers on the end of finger.
"I can't believe my big brother's been sniffing my knickers, if you'd have been 14 or something I might have thought it cute but at your age it's sick. And the boxers I want you naked."
I took my boxers off and my erection pointed at my sister. She walked around me slowly and deliberately looking at my body.
