Watching my best friend

Growing up with my best friend was different. We could see in each others bedrooms across a 40 foot space.

My family moved into a townhouse when I was 11, and there was two bedrooms on the top floor which one faced the road, and mine faced the other townhouse behind ours. The way building was shaped my bedroom looked right into the bedroom across from mine, but I had to put my face on the window to see any other windows. It was only a day or so I seen a guy across from me who was waving at me. School started in a couple days, and there was this kid who lived across from me waiting for the school bus. We became best buddies.

He was a bit more wild then I am, but we seen each other jacking off the porn on our phones in our own rooms at night. He had a sister who had the bedroom across from his, just like me, but his was a year older then he is, and my sister was my twin sister. When we got girlfriends we made a deal to leave the curtains open so the other could see the other making out with our girlfriends. This went on, and a few times I got to see bare tits on classmates without them knowing I seen, but my mom worked from home so it was impossible to sneak a girl up to my room without mom catching me, not that I didn't try many times.

Dan was my buddies name and he said I should try to get my sister in my room, and try to get her to take her clothes off. Well if I knew how to do that I would've been all over her long ago. I mean she got the body and the looks, and I just got the body. Dan said he was going to work on his sister to see if he could get her in his bedroom. Summer had just started with us finished with school, having passed grade 12. Our parents threw us a party for my sister, Dan and my 18 birthdays. Dan's sister was there and I was in lust with her, but she hardly would talk with me.

It was a couple days later I got a text from Dan saying for me to watch tonight. I went up to my room about 8 which is a little early, looking over not seeing anything. So I laid on my bed jacking off to porn on my phone when about 10 his lights went on. I turned my phone off, as I watched Dan's sister walked in his room looking around as Dan closed his door. He walked up to his sister putting his hands on her shoulders saying something, before pulling her in for a hug, before he pulled back kissing her on her cheek, then her chin, before they looked at each other then locking their lips together.

I couldn't believe what I was seeing, but Dan's hand found her ass cupping her, and she did nothing to stop him. Fuck how I wished it was me over there cupping that ass I love to watch for years now. As I watched she did the same to Dan pulling him in tight to herself. Fuck I would be grinding my hard on against her so fucking hard. Then Dan's sister slid her hands inside Dan's shorts he was wearing, and had to have her hands on his bare ass. Fuck I was so fucking close to blowing off in my underwear that I had to turn away with my sister, who I thought was away standing in my doorway looking at my tented underwear, as she said " What the fuck are you doing in here? " As see looked pass me at my window, and at Dan and his sister her friend.

My sister walked in looking at what I had been looking at when she said " What the fuck are they doing, he's her brother. Oh god she's not going to, fuck she sucking on his." I turned and seen Dan's sister on her knees sucking Dan's cock. I walked behind my sister who was wearing a pair of gym shorts and a t-shirt. I know I shouldn't but I bumped into my sister's ass with my hard cock. " Oh god Rick, he's taking her clothes off, and look at, oh that's so hot." My sister didn't pull away from my hard cock poking her ass, so I wrapped my arms around her with my hard on going between her legs, as I hugged her from behind. I felt my sister's hand go pass my arms and down to her shorts, as I felt her rubbing herself.

Dan now had his sister's leg over his shoulder, as he had his head between her legs with her hands both pulling his hair with her head thrown back. My sister was giving soft moans, as I moved a hand under her t-shirt rubbing her flat belly, slowly moving up to cup her bare tits which are smaller then Dan's sisters, but still more than a hand full. My sister bent her head back as I pinched her nipples, as a shudder went through her body. I kissed her neck, as my sister slid her other hand between us grabbing my hard cock giving a new moan.

I spun my sister around kissing her lips, as I slid my hands down the back of her gym shorts and on her firm bare ass cheeks. She had a throng on which left her cheeks bare for my hands to squeeze. I pushed on her gym shorts, and once they passed her hips hit the floor. My sister did the same to my underwear leaving me totally naked. I lifted her t-shirt over her head, as she looked back saying " Holy fuck, look they are fucking. He's fucking his sister." As I slid my sister's throng panties off her hips and out of the crack of her ass letting them join her gym shorts on the floor. I bent down sucking her nipple in my mouth sucking and biting it as I pinched her other nipple.

I kissed my way down pass her belly button looking at her shaved bare pussy, which I quickly kissed and licked before she pulled me to my bed getting on her back, as I went back between her legs licking her clit before sucking it with tiny bites as well. My sister was pinching her own nipples, as she started to cum. I kept licking her to one more cum, before I kissed my way back up my sister's body stopping at her nipples for a couple minutes, before poking against her pussy with my cock, as I kissed her lips. She said " Go slow I have never." As I slid part way in her tight wet hot pussy.

She arched her back, as I pushed hard feeling like a pop, with my sister screwing her face up like in pain. I stopped moving looking down at her as I asked " Are you ok?" She nodded, before saying " Ya the pain is starting to go away now, just go slow I have never done this before." Fuck my sister had been a fucking virgin, and I was her first. I broke my sister's cherry, and I love her for it. I slowly slid all of my cock in before slowly began fucking her. She had her finger nails dug in my back, as I slowly fucked my sister, she said " Go a little faster, and maybe harder too."

I did as she asked, I started fucking her as I felt my balls getting ready to fill my sister with my cum. I pushed hard into her, as my balls shot out my cum in her, as I also raise her legs up. I stayed put for only a second, as I started fucking her all over again. I was doing everything I could think of to get her to cum on my cock, I placed her legs flat against my chest with her legs going pass my head, with my hands under her ass she started to moan deeply. I placed a finger against her butt hole, and would pushed against it, as I pulled back with her getting oh so close, then she went tense, as she began to jerk. She just had her first orgasm from being fucked.

She said " You can't cum in me, shoot on my tits, but not in me, I'm not on anything." Oh fuck how do I tell her I have already shot in her once already. A fuck it, I won't say anything she won't get pregnant from her first time will she. In maybe 5 or so minutes I started getting close, so I said " Are you sure I can't cum in you? I'm fucking close, and would love to cum in you sis." She looked scared, as she she said " No pull out, you have to pull out, please." Maybe if she didn't say please I would've shot off in her again, but I pulled out shooting so hard it hit her on her cheek, and across her neck and tits. I let her legs down seeing spots of blood on my cock, as I looked up at my sister wiping my cum off her face with her fingers. I bent down kissing her hard on her mouth, before I said " I love you sis, I guess I always have. Thank you for letting me be your first. That is something so very special for you, to share with me."

My sister looked up at me before pulling me down kissing me just the way I had kissed her. She then said " We can't do this again without protection. So get some condoms, and I will ask mom to put me on the pill, ok?" I nodded before kissing my sexy sister once again. After some time she wanted up to have a shower. When she got up I saw I tiny bit of blood on my blanket, but I always was get cut in something, so mom wouldn't think anything of it. After my sister got out of the shower she stopped at my room saying " I'm happy it was you as well. I love you too." As she went to her room. My phone dinged with a text a minute later. It was from my sister saying maybe we can turn the light on with the curtains open next time.
