The story o[F] [M]y girlfriend asking me to fuck her sister

Dear people of r/gonewildstories,

I really enjoy reading all the hot stories that you share with us and I thought that it was only right to contribute something to this beautiful place and share the most gonewild story of my life.

This is the first time I’ve written such a text, so please be kind. Also I am not a native English speaker, but I hope it’s enjoyable to read even if some words are set or spelled wrong and the grammar is not 100% correct.

The story began with me and my girlfriend Sarah sitting on the couch and watching some movie on Netflix, when she paused and turned to me.

„Simon, I need you to do something for me, but it’s quite a delicate matter.“

I immediately knew that it has to be something very serious, because Sarah seldom acted so gravely.

„Honey, whatever it is, just tell me and I’m sure we can work a way out.“, I replied eager to know what was about to come.

Sarah started to tell me about her sister and her husband who have had their daughter Katrin born about a year and three months ago. Since then they have been all over her, taking care of her and are struggling to find any time for themselves.
They even set their alarm clock to 05:30 A.M., just so they can get some free time before Katrin wakes up.

Of course this is something that all parents have to deal with, but somehow Emma and her husband Martin found it especially difficult to do so.

They go out once in a month when Katrin is watched by her grandparents, but besides that it’s always the three of them together. During the weekdays Martin works from 9 to 5, so Emma takes care of the baby the whole day which leads to both of them being tired in the evening. On the weekends they try to show Katrin as much as possible and often take her on trips, so on every day of the week Emma‘s and Martin‘s energy is needed to raise their child.

At this stage of my girlfriend‘s story I started drifting away, since this was nothing new to me, when suddenly she said:

„They can’t even find any time to have sex anymore. Emma told me that it has been six months since they last slept together. Can you imagine?“

Now this was when everything started to turn interesting.

„No, I can’t imagine that they haven’t had sex for such a long period. Did they even try?“

„At least Emma tried, she told me.“

Sarah and her sister always talked about everything and so I wasn’t surprised that they talked about not having sex, too.

She continued to tell me that her sister often tried to seduce her husband, but he always rejected her, saying that he was too tired or didn’t want to wake Katrin up. And with every rejection Emma‘s frustration got bigger while her attempts became less frequent.

After that my girlfriend took a little break and then came up with the following words:

„Would you do my sister?“

My jaw dropped and I gave her the most confused look. Did she really just asked me to have sex with her sister?

„I know, I know, this seems so wrong and believe me, me and Emma talked about this a lot, but in the end you would do her a big favor.“

„You two already talked about me having sex with your sister?!“

„Listen, I love you. But I also love my sister and I feel so bad for her. She’s graving for some cock.“

„Wouldn’t that be weird? What about you? You can’t tell me that you’re fine with that!“

„It was kind of my idea, so yeah. I mean, she’s my sister, not any girl you would cheat on me with.“

I couldn’t say a word, I was too confused.
An awkward kind of silence was in the room, which was broken by Sarah‘s words.

„Take your time to think about it. Don’t hurry, I guess Emma can wait a little bit longer now. And even if you don’t wanna do it, I surely won’t be mad at you for not having sex with another woman.“

She smiled at me and continued the movie.

During the next days I did a lot of thinking. Since Sarah came up with this idea I couldn’t make it unheard. It was planted in my head and slowly started to grow.

For me, Emma has always just been my girlfriend‘s sister. And not in the hot and I would like to bang kind of way. We barely spoke too each other and had nothing in common.

She even wasn’t a bombshell to look at. I mean she wasn’t ugly or anything negative, but I always said to myself that I got the more beautiful of the sisters on my side.

Emma was about the same height as Sarah and had the same figure. Even though she already had a daughter, she was very slim. Her butt was a little smaller, but the tits were the same size. I know that for sure, because I helped Sarah to order a bra for her sister one time.

After a week or so I answered the telephone, when Sarah wasn’t at home. It was Emma who was calling. When I told her that her sister wasn’t around, she was just about to hang up when I said:

“I will do it.”

I don’t know why and what came over me in this situation, but after days of not getting this matter out of my head I thought that this was the easiest way to deal with it – just do it. Or in this case – her.

“Oh really? That’s awesome”

Emma sounded truly happy about my decision. We agreed that before making any further plans I should tell Sarah about my decision to get her final okay.

When Sarah got back I told her about my conversation with Emma.

“Oh honey, that’s so nice from you to do. Thank you!”

She hugged me and gave me a kiss. It was such a strange reaction to see from your girlfriend when you tell her that you are going to fuck her sister. But she was cool with it. More than that – she was the one to come up with it.

We decided that IT should happen during the two weeks that Sarah was on vacation with her parents, to avoid any awkward meetings. As if it wasn’t already awkward enough.

In the next three weeks our relationship surprisingly continued without any conflicts or fights. Everything was normal and the topic didn’t come up again.

But in my mind I couldn’t wait for it to happen. Since I decided to do it, I was really excited.
I knew from Sarah that her sister and Martin never had the most exciting sex life. And that she barely wore any thongs, because she didn’t like them. It didn’t mean anything to me. My mission was to give her a pleasure she hadn’t had for months and I wanted it to happen just like she wanted it.

When the day finally came and Sarah left to pick her parents up, she kissed me and winked at me.

“Have fun, honey.”

After she was out of sight I immediately called Emma. We had to plan everything. Her poor husband Martin wasn’t involved in this whole thing and that was an issue. Because this meant that Emma had to come up with a story that explained why she would be gone for a few hours and he would have to take care for Katrin during this time.

“It has to be on a weekend, because Martin doesn’t have to work and can watch our daughter. But what do I tell him why and where I am going? He wants to know everything about where I’m going.”

“Why don’t you sign him up for a father daughter activity? You could say that this strengthens their bond and it would be him leaving the house. He wouldn’t even notice you being gone in the meanwhile.”

“You know what? This is a damn good idea. I’ll let you know if it works and when we can meet.

This must have been the longest conversation we ever had.

Until the next day I didn’t hear anything from Emma. But in the evening she called. It was just these three sentences that she said, before she hung up again:

“Can’t talk right now, Martin’s in the bathroom. Next Saturday, 3 PM. I’ll come to your place.”

It was on – in two days.

On Saturday I woke up super early. I was too excited. The time seemed to pass with only half of its usual speed. I already cleaned the apartment, went jogging, ate something and took a shower, but it still was only 1 PM. The last two hours I spent sitting on the couch and waiting without really doing anything.

Shortly after 3 PM the doorbell rang. My heart skipped a beat – this was it. I opened the door and waited for Emma to come up the stairs. When she saw me, she just said Hi and entered the apartment. She seemed a little bit passive, but I guess she was just as excited as I was.

She was wearing her usual outfit, consisting of a pair of jeans and a plain sweatshirt. Nothing too special for this special occasion, I thought to myself.

We were both standing awkwardly in the hallway, because we didn’t know what was coming next. Should I first offer her a drink, or should we have a chat on the couch?

Emma must have asked herself the same questions, but luckily she took the lead and headed to the bedroom.

“Let’s Go, we have something planned.”

“Okay. Since this is all about your lust, I need you to tell me what you want to do.”

I followed her to the bedroom where she already stood in front of the bed. Emma told me to get undressed and lay down.

„Before we start I want you to know that I want to this to be really dirty. Martin and I never used to be really kinky and as you know he’s the only guy I’ve had sex with. I want to make things I’ve never done before.“

That was just fine for me and I took off my pants and sweatshirt ending up only in my boxershorts.

Emma told me to close my eyes and I followed her commands. I could hear her unbuttoning and unzipping her pants. Then she took off her sweatshirt.

„You can look now.“

I opened my eyes and couldn’t believe what I saw, as she was standing in front of the bed. Her body looked exactly the same as her sister‘s, it was like someone only changed the head. Her skin was perfectly pale with some freckles on the chest. Emma wasn’t super sporty, but there was no fat at all on her body.

Most surprisingly she was wearing some very hot lingerie. A beautiful black bra with some lace was wrapped around her boobs. I knew she was a 75B just as Sarah and I also knew that I would totally love her breasts. Below she wore a tiny thong that was barely covering her private parts. The outfit was perfectly completed by her stockings.

„To be honest I did not expect such a hit tease from you.“, I said to here still being amazed of what I saw.

„I know, this isn’t my usual outfit. I bought it just for today. I hope you like it.“

Oh boy, did I like it. I told Emma to turn around so I could see her whole body. The small string of her thong vanished in the cheeks of her perfect little ass and I couldn’t wait to feel and touch her body. One time I spied on her through the key whole when she was around to try on a pair of jeans from Sarah, so I already knew the sight of her sweet little booty.

I moved to the edge of the bed and laid both of my hands around her hips gently pulling her towards me. As she was still standing and I was siting her ass was right in front of my face. I kissed her cheeks and took a little bite into them.

Emma turned around and pushed my head against her body. My hands were massaging her booty while I was now kissing her vagina through the thong.

Then she pushed me away down on the bed.

„Get those boxershorts off!“

As I moved up the bed I removed my boxershorts and my already rock hard dick jumped out. Emma got on top of me and immediately started to rub her pussy against my dick.

„Why don’t you sit on my face?“

With that being said Emma stood up and pulled down her thong. From below I could see how wet she already was as strings of her pussy juice ended up from the thong on her legs.

„Do you really want this?“, she asked me while she placed her legs left and right from my head. I nodded and grabbed her ass. She lowered her body and put her pussy right onto my mouth. She placed her hands on the wall and slowly started grinding on me. I just put my tongue out and moved it around in circles.

Her pussy was so wet I could literally drink her juice and had to swallow a few times, but her taste was just unbelievably good. She slowly started moaning which got a little louder when I moved on of my hands from her ass to her bra. I gently moved my fingers into the bra and could finally feel one of her breasts. Her nipple was already very hard and I started playing with it.

Slowly I was struggling to breath, because Emma was riding all over my face and her pussy produced more and more liquids. I don’t know how, but she must have noticed this and stopped for a second.

„I’ve never been licked this good!“, she said, although she did most of the work and I just had to stick my tongue out. „But now it’s my time to return the favor.“

She just wanted to go down on me when I proposed that we can both have fun at the same time.

„You mean 69? I’ve never done this before, Martin never wanted to try this.“

„Well you wanted to get dirty and this is the perfect chance.“

„You’re right, let’s do it.“

She turned around and placed her head on my dick.

I have to admit that I’m a huge fan of 69. I just love the view you have and this time it was no disappointment neither. While Emma started to lick the tip of my dick I enjoyed her pussy and her asshole right in front of my eyes. Slowly I started licking her pussy while I spread her ass apart with my hands.

Unfortunately Emma is even more like her sister than i had noticed until now. Her blowjob skills were as poor as my girlfriend‘s. I couldn’t even tell you what she did wrong, but I did not quite enjoy it as I was probably supposed to. But I also didn’t want her first 69 to stop after just a few minutes. So I concentrated more on giving her a pleasure than her working my cock.

I now wanted to finger her in addition to my licking, so I gently put one of my fingers into her pussy.

This must have been too much for her, because she stopped giving me head and screamed a loud „Oh my God!“. I could feel her pussy pulsating around my finger. After a few heavy waves of her orgasm her body completely relaxed and she rolled down from me.

„Wow…“

Emma could barely speak and was breathing heavily. It felt good to know that I could give her exactly what she had been waiting for the last months. And I could also feel all the tension that was now coming off her.

As she was exhausted lying next to me I was gently stroking my cock.

„Oh no, now I totally forgot about you. I‘m so sorry, but my pussy is so sensitive after I cum, I cannot let you in right now.“

„Don’t worry, this was all about you, and that’s all that matters.“

„I know just how to make you happy, too. My sister told me that you like to cum on her ass, is that right?“

Sarah, I love you for sharing everything with your sister.

Emma rolled over, now lying on her front and put her ass up in the air. I grabbed one of her cheeks and gave the other one a smack. I rubbed my dick against her soft skin and began to stroke it faster. It did not took very long until I shot my ropes of cum onto her. Half of her back and all of her ass got covered with my cum.

Relieved I let myself fall down next to her. But there was no time for her left. She asked for a towel and I got up to bring her what she asked for. She cleaned herself and got up.

„Mommy needs to go back to her normal life.“, she said and began to undress her bra and stockings.

This was the first time I saw her tits and they were just the same as the ones from her sister. From the bag she had brought with her she took out a plain white bra and a rather granny-like panty. Now I knew what Martin got to see her in. She left the lingerie on the bed, put on the rest of her clothes and left the bedroom. I guided her to the apartment‘s front door and watched her leave. She did not speak any more than a short „Thank you.“ when she was walking down the stairs.

Back in the bedroom I took a deep breath of her soaking wet thong, knowing that this would help me to get off a few more times.
