Just told from his side, as opposed to mine
My first time trying to write from male perspective
***
"Yeah Mum, I know, she is back today," I shouted downstairs.
"Remember it is her room as well," she shouted back.
"Yeah mum, I know," I shouted back as Mum and Dad left for the weekend.
My sister was back from University for the holidays, so once again I had to share a room with her. I was 19 years old, she was 18 and although she was my sister, she was pretty hot. As we had shared a room all of our lives we were close, you kinda had to be or life got awkward quickly.
She got back late evening and after the usual pleasantries were exchanged I let her have the room to get sorted knowing she would be going for a shower. I went downstairs noisily but then crept back up and peaked through the gap between the door and the frame. I know it is pervy, and probably wrong on so many levels, but I had "spied" on her for a fair few years. She was my sister, my friends all fancied her and although I would deny any attraction to her although I had to agree that she was hot and if she asked I would...
She was wearing her jeans and t-shirt as she wandered around the room doing whatever it is girls do. She eventually took her top off showing her white bra underneath, shame she was facing away from me as she also slipped out of her jeans. I felt my cock stiffen a bit in my trousers as I saw her in her underwear. She was wearing black panties which although not a thong were a fairly high cut and were showing a lot of her very sexy slim legs.
I had seen her loads of times in her underwear, seen her topless a few times as well as once or twice totally naked. I was fairly sure that she was shaved, but the view through the crack of the door isn't that clear. I had considered setting up a camera to record her, but always wimped out being scared of getting caught. She slipped on a dressing gown and started to walk towards the door so I bolted downstairs again.
"Gonna get sorted for bed," I said through the bathroom door.
"K k," she said back.
I stripped to my boxers and got into bed, I had got into the habit of sleeping naked since she moved out to stay at Uni during the term, but kept boxers on when she was back home. She came back in after 10 minutes or so wearing a mid thigh length t-shirt and although I couldn't see, I assume panties as well. She got straight into bed leaving the main light on.
"Erm, Light..." I said.
"Oh crap," she said, "You not get it?"
As the light was nearest to me I leaned forwards and clicked it off. She didn't say anything as we watched the TV which was one of the many police action programs. Out of the blue she said, "You naked?"
"Just boxers." I said back a little taken by surprise, "Why?"
"Was just wondering, didn't see any when you switched the light off," she answered.
"Oh, so you were looking were you?" I said smiling at her
"Not really," she back tracked before adding, "Was just wondering,"
I just smiled at her. Deciding to take advantage that she had asked, I asked "What you wearing?".
"Erm, t-shirt and shorts," she answered. They must have been short shorts as I couldn't see them under her t shirt that wasn't massively long, well above her knees.
"Underwear too?" I asked.
"Yeah," she said, "Well, panties. I don't have a bra on."
"It is so much cooler and comfier topless, plus cheaper as you don't need to buy PJs," I said, "Why no bra?"
"Comfier," she said.
"You ever slept naked?" I asked, "That is super comfortable," I added as I felt a stir in my boxers.
"Don't feel comfy naked, can't sleep. If it is hot I go topless, too fidgety, would lose the covers or something." she explained.
"Fair enough," I said, "Shame it isn't hot," I added sticking my tongue out at her.
"Perv," she said returning the sticky out tongue.
"Meh," I shrugged, "Tits are tits."
She laughed, "Seriously? You're brain really is in your dick isn't it."
"I am a bloke," I said, "If you fidget wouldn't it make sense to keep your top on?"
"Why?" she asked.
"You are more likely to lose the top half of the covers than the bottom half aren't you?" I reasoned as I imagined her only wearing her panties... or less.
"Yeah, suppose so," she agreed, "Can't sleep bottomless though."
"Fair enough," I said rubbing my stiff cock under the covers making sure it wasn't sticking up or noticeable.
"You still a virgin?" she asked me again surprising me.
"No," I said instantly regretting my obvious defensiveness.
"Really?" she pressed, "No macho shit, I don't care if you are or aren't."
"Are you?" I asked me.
"No," I said.
"Really. Good first term then was it?" I said sitting up, "How many?" I asked smiling at her.
"Cheeky fucker," she said, "Just the one."
"One nighter?" I asked.
"No, we lasted a few weeks before it turned out he was a freak," she said.
"Fair enough," I said, "Did you suck his dick?"
She laughed again, "I don't think that is any of your business do you," she said grinning.
"That is a yes then," I reasoned, "Lucky bastard."
"And swallowed it too," she said sticking her tongue out at me.
"Dirty bitch," I said smiling, "Did it taste nice?" I asked not really expecting an answer and as expected not receiving one either.
She just smiled at me and continued to watch the TV as my mind raced imagining what it felt like being sucked off by anyone. She changed the channel to something else which I didn't really pay attention to as my mind imagined her in all sorts of deprived positions. Once I had control and my erection had reduced I said I was gonna go for a pee.
"Pee or a wank?" she said to me sticking her tongue out.
"Just a pee unless you are offering to give me an image for the wank bank," I said back.
"Wank bank?" She asked sounding a bit confused, "What is one of them?"
"Never heard of a wank bank?" I said, surprised she hadn't heard the term before.
"Nope..." she said, "Although it doesn't sound particularly nice."
"A mental image used for erm... self-satisfaction moments," I explained.
"Hahaha, perv," she said.
"Male," I clarified as I stood up and went out and to the bathroom.
Me and my sister had spent hours and hours talking through the night. Admittedly never the topic of sex in this depth before. I stood in the bathroom considering having a quick wank, but decided against it as it would take too long and be obvious what I had done.
"Sorted," she asked.
