“I Love My Sister”
(I wrote this story from a DM I got about a year ago on my now deleted Instagram page…
“…. My sister is so fucking hot. She’s a cheerleader, and 16. Something happened two months ago, that I can’t get this thought out of my mind. It was the Fourth of July. She just got her license like two or three months earlier. I was younger than her. My parents allowed her to go out until 10:00 on Summer nights, in the minivan. She had a boyfriend. Her boyfriend didn’t drive yet, so she was always driving him around. This particular day, I got in a fight with my Mom. I wanted to go with my sister to go see the fireworks, but my mom didn’t allow me, and my sister didn’t want me to go with her and her boyfriend. I was so mad, that before my sister left, I went and hid in the back of the mini-van and used a blanket back there if I had to hide.

When my sister came out, she didn’t look or anything, and I was in the clear. She picked her boyfriend up and she was giggling, and I couldn’t really hear what they were saying over the radio. I did notice that I wasn’t seeing any buildings out the window, just a bunch of trees. We should of been at the parking lot where the town all gathered to watch the fireworks. She parked. For about ten minutes they were making out in the front seat. Then she turned down the radio, and they got out. They opened up the backseat sliding door! Damn. They were getting in the backseat.

Now, with them just on the other side of a cushion, I could hear them quite well. I thought I was going to just hear them kiss and stuff, I didn’t even think they were going to do anything else. I guess I just thought of my sister as the good girl. The cheerleader, straight A student type. “I think it will fit…., I was opening myself up in the shower before I picked you up.”…she said. This was a complete shock. You have no idea.

Suddenly, the girl I can’t stand, and argue with all the time, was turning me on by that one sentence. What in the hell is wrong with me? I was excited to hear what else was going to happen, yet I was so afraid of getting caught. Her boyfriend is a jerk. I’m not even going to quote him because all that came out of his mouth was “oh, that’s hot, it feels so good, blah, blah, blah..” I heard them taking off their pants and underwear. My sister threw her cloths right on top of me. I knew I was going to have to move them before they were done. I reached out and took her sweatpants and her cute little dainty panties, and put them next to me. I was able to see a great reflection in the back window of the van, because they had the light on, and it was dark outside. I saw my sisters head disappear, so that must mean she was blowing him. Heck. The noises of sucking cock filled the van.

“Mmmm, I’m ready to try, ‘he’s’ready!”.(referring to his dick)..All I could see was the back of my sister’s head, and thru the reflection, I could see her fumbling underneath herself. She was going to ride him. I only saw this stuff in porn at my friend’s house. This was my sister! It was giving me the hardest boner I have ever had up until that point. I think if you just touched me down there it would of went off. I think my pre-cum was starting to be actual cum.

“Oww!”she said. “Let me turn around”.. Shit! I could see her head was right above me in the reflection! All she had to do was physically look down, and it would be all over. It doesn’t take much to wonder what’s under this big blanket. Luckily, she didn’t see it, or she didn’t care. She put her hand down just above me, and spit into it…I could see her reaching around behind her. It looked like she was wiping her ass with it? She must be really tight with the facial expression of closing her eyes and gritting her teeth. “Mmm, mmm, almost..”she said, obviously sliding down on his cock. “It’s going in,..shit, it’s in!..it’s all the way in, shit! Oh, shit! My ass! It feels so good in there. Mmm. It hurts so good!..okay, okay,..stay right there for a minute…….,…alright,mmm”, she said.

Holy crap! She’s taking it in the ass! I thought. I was so fucking turned on. I couldn’t control myself as I grabbed her panties and started smelling and licking them. I wanted it to be me fucking her ass. I wanted to see that thing going in her. What a fucking turn on. “I’m in, baby!..you feel so good.” With the grimace on her face, in the reflection, I couldn’t tell if she was loving it or if it was painful, but she was coming up with her body. “Shit, baby, it feels like your splitting me in two!”

“Mmmm” she said, gritting her teeth before taking a couple deep breaths and sliding back down on his cock. She wanted to push it back up in there. She started to pick up speed. I could tell she was enjoying. She had her eyes closed, playing with her tits, as she rode up and down on his manhood.

“Oh, God baby! I think I’m going to cum!” She blurted out, while going like a piston on his cock. I can’t believe my sister had a cock IN HER ASS, and I was so fucking turned on! Her boyfriend was making all kinds of noise, like he was getting fucked himself. I could hear her playing with her pussy. Damn, I wanted to see it. I can’t believe I just said I want to see my sister’s pussy..She must not shave it bald either, I could hear the sound of wet kinky hair when she played with herself. I could see her face making all kinds of expressions of gratification.

She slowed down on his cock. “Do you still want to fuck my ass, or do you want to finish in my mouth?” He asked her where she wanted it. She said, “in my ass…”, and giggled. She started riding him again. But, this time I could tell she was more confident, and really enjoying it. She was running her fingers thru her blond hair with her eyes closed.Bouncing up and down. She sounded so wet,..and opened. I want to fuck her. I want to see her naked. I want to see that ass that is getting fucked. She was swaying. She must of been circling her ass on his cock as she went up and down. “Mmmmm” was all she was saying this round, until her boyfriend really started to lay into her.

“Uhh, uhh, you gonna cum for me baby? You gonna cum in my little ass? Cum for me baby”. I felt she was talking to me, because I was about to jump over the seat and make a three way. About thirty seconds of the gushy sound of her ass being plundered, moaning, and the motion of my sister bouncing up and down, her bf blew his nut deep inside her. I could tell by the “Mmm, that feels good”, and her trying to catch it all somewhere far up in her by her looking as though she was trying to smash something with her ass. I cannot believe I didn’t blow a nut myself. I was so completely turned on.

She eventually dropped him off and headed home. I didn’t care or even know if they made it to the fireworks, I felt like a man after that. All I knew was, if I went up in my treehouse, and say that I am sleeping up there, I could see into my sister’s bedroom, or the bathroom. I could not wait to get home and bear off to my sister, regardless of what she is doing in either of those rooms. I was on spy mode the rest of the night.

We got home, I waited until my sister was inside, then got out ran into my mom’s room and told her I was out in the treehouse, and I wanted to sleep out there. She was fine with that. I was up there before my sister even made it up the stairs. The bathroom light came on. In she came. She pulled down those sweats and her sweet smelling panties. I was erect again.

I took down my pants and started stroking my cock while I watched her. Her pussy was perfect. A little bit of hair, just perfect. It sounded earlier like she never shaved it, but I see now that she did. Wow, she picked up a hand mirror and opened her ass with one hand and stared at her hole in the mirror. Fucking sexy as shit.

I whacked off thinking about my dick going into that bored out hole. It was a gooey mess. I loved it. She sat on the toilet and I could hear her expelling all of her boyfriends cum. She got back up, opened the window, and threw her panties out onto the roof towards her bedroom window. I was guessing some cum came out on the way home. Now, this was an extra bonus. Those were going to be around my head like now. Damn, I wanted to put my whole face in my sister’s tight 16 year old ass.

She fumbled thru the drawer and got one of our wide-handled hairbrushes out. She turned the shower on, and took off her sweatshirt. Damn, my sister is built! I could cum at any moment. She got down on all fours, stuck her ass up in the air, pointed right at me, and inserted the handle of that brush in her ass! I’m literally loving this right now. I took out my phone with my free hand and started to video it. With the screen open in the bathroom window, I could hear her talking to herself, like she was still talking to her boyfriend. “You like this ass, do ya, get one of your friends” I clearly heard her say.

She started fingering her pussy from underneath, while sliding that brush the whole way in. This was so fucking hot. You have NO IDEA. I felt in coming,…aaaannnd there it was! Damn, an explosion of cum all over the floor. It felt like a gallon of the milky white stuff. Shit. I still watched her as she finished up, took a shower, and got out of the shower and went to bed. I just saw her rinse off that brush real quick. I went back inside, and took the brush. I wanted to taste it. All and all, this all was far better than any fireworks. I am going to watch my sister every night from here on out. I want to fuck the shit out of her. I’m going to be extra nice, and maybe she’ll let me….”

This kid was really into his sister. I wrote this a while ago from like 5 direct messages he sent me. He even sent me a picture of his sister in a bikini. He said he had nudes, but I wasn’t interested. Because I’m sure she didn’t know about them being taken, and I’m really not into that. But, whatever. Anyway, I hope you enjoyed this. This was a true story for the most part.
