Exploring with girlfriend and girlfriends sister threesome [FMF]

My GF (20F, let’s call her Sophie) and my GF’s straight sister (19F, let’s call her Katie) are very close and have been eachothers best friends their whole life. They both look quite similar, with athletic bodies and are both quite short. Throughout our relationship, Katie has always been really close and involved in our relationship to the point where we hang out a lot, have all see eachother naked before and talk about anything together. Me (20M, straight, in good shape) and Sophie are both really open about sex and love showing ourselves off when we’re drunk/high to our closest friends. Me Sophie and Katie are all very close, and do MDMA together sometimes where we all become very ‘comfortable’ together.

The last few times where we have done md together, Sophie and Katie usually like comparing their arses (as they’ve just started working out their bums) so they usually end up taking their trousers off and revealing their perky bums in laced thongs and ask me to take a picture of their bums together so they can compare them.

However, this one time when we were pinging, I felt horny and plucked up the confidence to tell them to take off their bras as well and pose for a picture with their boobs out and to my surprise, they both took them off instantly and started posing for a picture with their boobs out. They both have quite small boobs but they have really sexy perfect nipples, which made me so horny as I was seeing two sisters topless posing for a picture together. Whilst they were standing there I asked if I could touch their boobs to compare the difference, as Katie has slightly bigger boobs than Sophie and Sophie’s boobs are the only ones I’ve ever seen naked before at the time. And because we are all so close and comfortable she said yes, and I squeezed Sophie’s boob in one hand and Katies in the other. We all just laughed and eventually they put their underwear back on and we carried on talking and cuddling all together.

At some point we all went to the toilet together to pee, as we didn’t care because of the md and we all went to the toilet at the same time to continue talking. When it was my turn to pee, I took my dick out and decided to show it to Sophie and Katie because it had shrunk so small because of the md, and we all giggled at my pilly willy, and because when you’re on mdma, your penis usually feels quite weird and rubbery. So I told my gf Sophie to touch it as it felt so strange, so she grabbed my dick infront of her sister and laughed at the feel of it. Sophie then said to Katie that she should feel it, and so Katie asked Sophie if it was okay, as she seemed hesitant that she might be crossing a boundary, but instead Sophie almost encouraged her to feel it. So Katie then grabbed my penis and started playing with it to feel how strange it felt on md. We all just giggled but even though it’s difficult to get boners on md, I started getting really horny by seeing my girlfriends sister playing with my dick infront of my girlfriend, and started slightly getting bigger, but she stopped before it became noticeable.

We all peed and went back to the bedroom where we had been chilling all night, and began cuddling with Sophie and Katie with them laying on each side under my arms, with my hand on each of their arses. As me and Sophie are both very open minded and enjoy showing our nudes and sex tapes to people, we all just sat there whilst we looked through them together, showing my dick pics to Katie, where she was shocked at how big my dick was as she just saw it so small in the bathroom. I have a 7inch dick with a 5.5 inch girth, so Katie was surprised when she saw them. Sophie asked Katie what she thought about my dick pics and she instantly started complimenting it and saying to Sophie how lucky she was as she was sure it must’ve felt nice inside her, especially because Sophie is only 5ft, so 7 inches must feel quite big for her.

We continue looking through our nudes and even showing explicit photos of sophie tied up with her legs spread open, and Katie didn’t seem to mind seeing her sisters pussy in full glory, and even went on to say that Sophie has a really sexy pussy, which caught me off guard as Katie is straight and wasn’t expecting her to make comments like that about her sisters pussy. Because we were high and all feeling confident and comfortable, I mentioned how I wondered if Sophie and Katie had similar looking vaginas as they were sisters. The both looked at eachother confused and curious, and they both said to eachother that the don’t mind getting them out to see, as long as Sophie was comfortable with me seeing her sisters spread pussy, but Sophie was more than okay with it and Sophie jokingly said she honestly wouldn’t care even if I fucked poppy infront of her (we didn’t fuck then, but Sophie was just making a point). We all just giggled and the girls both started removing their underwear to reveal their pussys to me. At the time Sophie had grown a sexy landing strip, whilst Katie was clean shaven. This was an insane moment for me. I had always fantasised about threesomes with them both, and now I had these 2 cute petite sisters who I loved both a lot, both spreading their naked legs in front of my face. They both asked me what I thought and I struggled to get my words out, but all I could say was “this is the best sight I’ve ever seen” and the both started blushing and giggling.

I then looked at both of their pussies really close up, my face about a rulers length away from each of their pussies. I looked at them and they both had fairly similar pussies, except Katie looked much tighter as she had only had sex once before, whilst I have fucked sophie probably 1000 times. When I was inspecting Sophie’s pussy I quickly licked her clit before anyone could do anything, and she let out a small moan. I apologised and said that was naughty of me, and said sorry to Katie if I made her uncomfortable watching me quickly lick her sisters pussy whilst she was there. I said I was too horny and i couldn’t control myself. She giggled and said she didn’t care, she thought it was funny. Sophie jokingly said that because I licked her clit, it was only fair I did the same to Katie. Katie blushed and I could see she was wet, as the lips of her pussy were slightly glistening. I looked at Katie and couldn’t tell if she wanted me to or not, as I was her sisters long term boyfriend. Sophie began to cheer me on and started chanting “lick that pussy, lick that pussy”, so I looked at Katie and she shyly said okay do it if it’s okay with me and Sophie. So I looked at Sophie who had a massive naughty grin on her face, and so I licked Katie’s pussy slowly from bottom to the top, tasting the cum that she had been leaking. Katie let out a louder moan than Sophie , and Sophie started laughing and clapping when I was done. Katie face was bright red as she was shy for moaning at her sisters boyfriend/best friend licking her pussy. I told her that she had a really nice pussy and that her cum tasted really good too. Which must’ve made her feel happy as she’s usually quite insecure and shy. She blushed and said thank you, as she started to feel the cum leaking from her pussy lips with her two fingers. Sophie commented saying that she found that incredibly hot.

Side note: Sophie told me the next day that she got turned on by it, seeing the 2 people she loved most pleasuring eachother, and she didn’t get jealous or mind because we were all so close and open about anything together anyway, and knew that all we were doing was just having fun together. Sophie doesn’t see sex as anything other than sex, as long as she’s there and involved. So me licking her sisters pussy infront of her was all just fun because we’re all so close and just having a good horny time on md. And didn’t see it as weird or strange that it was her sister, because they have been close their whole lives and have only had eachother as they didn’t really have many friends growing up. It wasn’t weird or awkward because we were all just having fun and it wasn’t intimate or anything.

Back to the story. We all just laughed and the girls put their thongs back on all sexy in sync like they were putting on a show for me and we all got back into the position we were before cuddling with my hand resting on their arses. I said that was really fun, and thanked them both for being so cool. Sophie replied saying that they would return the favour all jokingly if the md didn’t prevent me from getting a boner. Katie surprisingly said to Sophie that it would be fun sharing my big dick between the two of them. To where I began to start blushing. The both just began to rest their hand on my bulge and slowly playing around with it whilst we continued talking, cuddling and chilling for the rest of the night.

Nothing else too crazy happened for the rest of the night, we all just continued to talk about other sexual topics and just normal conversations for the rest of the night until the md wore off and we got tired and went to sleep. We all got in the bed, and we all cuddled in our underwear with them both laying on each side of me chest and we all fell asleep fairly quickly.

The next morning we all woke up exhausted and hungover. We all just said how we all had a fun night, and never mentioned what went on that night, and all just got on with the rest of the day as normal without any awkwardness or weirdness. We all just acted as normal and in a way we were all just closer and all in good moods.
