Older sister

This is a story how I fucked my girlfriends older sister

So me and my girlfriend started dating a few years ago as when she was 15 i was 16 and her sister was 17. I got along well with her sister we’d always make super flirty jokes. 2 years later when I turned 18 and she was 19 things took a turn. She had this boyfriend who she dated for many years since they were in public school. She ended up breaking it off with the guy because she wanted to time to be herself and experience other things. I am 6 foot toned build 160 pounds. She’s probably 5’5 170 180 pounds. She’s not fat by any means but she’s a thicker gal. She has huge tits and a medium sized ass and a gorgeous face. One day early in the morning when I woke up my gf was sleeping I decided to go shower.

I get into the shower, it’s an all glass shower so you can see right through. Me and my girlfriend were going thru sexual problems and I remember her sister telling me every guy she’s had sex with has had a small dick from 3-4 inches. I’m almost 7 inches. I instantly got hard thinking what would happen if she seen my dick would she get turned on or would she be grossed out cause I’m her sisters bf. We always make Pervy jokes like I’m gonna suck you dick or eat your pussy, make babies. Stuff like that even around my gf she doesn’t care she thinks it’s funny.

I heard this knock in the door I yelled I was showering. It was her sister saying she rly has to pee. So she opens the door and comes right in. I’m standing there harder than ever flexing my dick hoping she would see it. She covers her eyes and puts her head down. My hopes were up. At this point I didnt care I noticed when she walked in she looked right down at my dick so she seen it. I open the door with my dick hanging down and say “you really had to pee that bad” she looks up but doesn’t make it to
My face. She’s staring at my dick I don’t think on purpose I just don’t think she could look away, she ends up putting her hand out to cover my dick and says “your dicks hanging out” I say “well it’s not like you just didn’t see it I don’t even care at this point”

She started laughing and says “I guess” moves her hand i went back into the shower. I couldn’t hear her peeing anymore but act like I didn’t notice while she was just sitting on her phone glancing up at me every once in a while. She eventually sat up and I got a peak of her pussy but she didn’t notice that. I started washing my dick rubbing soap on it like I was almost masterbaiting. She could see it clear as day. I glanced over and she was looking at me while she was walking out.

We never spoke about it, or neither did she tell my girlfriend. Months later we all took a trip up to the city. We all got black out drunk. We were in her room when we were just goofing around. She would dance like she was crazy but she was wearing this low shirt almost to where her nipples were showing. My girlfriend went to the bathroom and continued to dance like that. Her boobs ended up slowly falling out her shirt while she was twerking on the ground. She was wearing a skirt so I could see her ass and pantys clear as day. We were both so drunk I didn’t even think anything of it and neither did she.

My dick was hard but I was drunk and surrounded by people and she was goofing around I didn’t think anything of it. We ended up going out to the bar that everyone could get into cause there was some people not of age yet. We passed by this club and her sister asks my gf if me and her can go in for a little since we’re the only ones of age. My gf was hesitant at first but we were with her entire family so she just said sure we’ll just be at the bar waiting. We go in the club was packed and we get some drinks.

Mind you we’re already shitfaced. We go into the back and start dancing. She was drunk falling everywhere where I can hold my liquor so I held her. Some old guy came up and asked if she was single. And I said no I’m her bf. “So you’re my bf” she says. “Tonight I am” I say back. We end up dancing more and I feel her ass agasint my dick. She starts backing all the way up to we’re at the wall where it’s dark and no one is. She lifts her skirt and I see her pantys are gone not sure where they went but they were gone. I’ve been hard ever since I seen her tits and ass but did the old wasteband trick. I feel and see her start rubbing her ass right against my dick for a couple seconds then puts her skirt back down.

I was stunned to speak. She stands on her tippy toes and whispers in my ear smiling “ I like your dick “ this made my body go into shock and my temptation only grew stronger. We both said we have to go to the bath room. I get in there and I go to the very back stall. I notice a Decent sized hole in the wall. I look over at the hole. There she is looking right back at me. “Is this what I think it is” she says I go “no way” with both of us laughing. The toilets were faced right at eachother so when I look left I can see her peeing with her legs spread meanwhile if shes looking straight she can see my dick from the side.

She falls over to the ground crawling to the big hole you couldn’t fit through the hole but definitely get your ass thru. She goes “let me see it” “this is what you wanted right” I gulp and said “yeah”
I stick my dick thru the hole and her warm mouth wrap around it with her tounge licking my head. She starts sucking it like it’s a lollipop and I’m feeling great. I told her I was gonna cum and she deepthroated it until I shot it down her throat. She end up standing up and lifted her skirt up and said “my turn” I stuck my head and arms grabbing her by her ass and spreading her cheek and started licking her clit. She started pulling my hair and light moaning you wouldn’t hear it over the music.

That’s when I hear my gf call her name from the bathroom and we both just acted like nothing happened when we got out. We went to the bar to drink some more before we all headed back to the airbnb. It was getting late eveyone was sleeping I was laying in bed next to my gf who was sleeping. I decided to go walk out and grab a snack hoping I would see her. I didn’t. I was walking back up to the room when I got a text from her “is anyone up” my cock got hard again “no everyone’s sleeping” I txted back. “Come to my room” she says.

I walk in there she is. Completely naked, fingers in her pussy and ass. She goes “come on we got to be quick” my pants flew off, she was soaked she smelt like sweat since we hadn’t showered at all but it was a good smell. I stuck my dick right into her in missionary position and started going to work. She was trying not to scream because this was the biggest dick she’s ever taken. I flip her over and she goes on all fours I’m pounding her. I don’t think I was being quiet at all. I go “I’m gonna cu-“ “do it” she says in a naughty voice that still turns me on to this day thinking about it. We both cum at the same time. She’s yelling in the pillow, I’m biting on her back trying to be quiet.

She looks at me and goes “you filled me”. I look back and go “anytime”

We still do some things here and there. I have some more story’s about us if anyone wants to hear.
