True story from visiting my sister in Barcelona

This is a true story and I’m using a throwaway account as I wouldn’t want any of my friends to ever see this but it’s something I need to get off my chest.

So long story short my (M23) sister (F21) was studying abroad in Barcelona last summer. My family decided to take a trip to Spain while she was there and link up with her the week she finished. We’ve always been super close and been extremely open sex and our experiences compared to the average siblings. We also over the year have been flirty when drunk but nothing ever came of it as I think we both realized how wrong it would be.

When we got to Barcelona to meet up with my sister my parents got two rooms, one for my sister and I and one for them on a separate floor. I was excited to see my sister as I had been with my parents the last three weeks and was looking forward to going out with her and her study abroad friends to experience the night life in Barcelona. The first morning we got there we checked into the hotel then headed to the beach with our parents. It just so happened to be a nude beach which obviously none of us took part in but after seeing families there where the moms and sister were naked I wished I could see my sister topless. My sister is definitely “hot” and I’ve always gotten shit for it from friends. She’s blond and 5’7 with an athletic build with large breast (guessing Cs) and a big butt.

After the beach we went back to the hotel to get ready for dinner, which my sister and I (both big drinkers) began pregaming while getting ready and catching up. After dinner with my parents they headed back to the hotel and my sister and I headed to the local bars to meet up with her friends. If you’ve never been to Spain there’s a drink called absinthe which is illegal in the states and I was excited to finally try it. Once we met up with her friends we spent the next 4 hours bar hopping, dancing and taking way too many shots. At about 2am her friends decided to call it a night and my sister and I headed back to the hotel. Both of us were drunk to say the least and as we walked we linked arms chatting about her time in Spain and just catching up. As we got close to the hotel (which was on the beach) my sister suggested we jump in the ocean. I was drunk so I didn’t hesitate to say yes. As we got to the beach my sister slipped her dress off revealing a white thong and white bra. I stripped down to my boxers and we both jumped in. Once in the water she kept jumping on me and playfully horsing around, continually touching me and making flirtatious comments about my body (I’m 6’3 and fit like her). After about 15 minutes we decided to head in to the hotel to go have a drink and smoke some Cuban cigars (she’s also a bro lol). As we headed in to the hotel both soaking wet and drunk she held my hand. When we reached the elevator there was a young couple who I believe were newlyweds who we struck up a conversation with while waiting. They asked if we were married and before I could answer my sister jumped in and said no we were boyfriend and girlfriend and studying abroad together. This caught me off guard but this also is up my sisters alley as she’s notoriously sarcastic. We were holding hands so I guess it would’ve been weird to say we were siblings. The couple asked if we wanted to have a drink in their room despite us being soaking wet still and we accepted. Once in their room they asked us about our relationship and how we met as we had gin and tonics, at this point I was joining in with my sister in making shit up. We told them we were in our late 20s and made up careers, where we lived, etc. asking them the same questions.

At some point the girl started to ask us about our sex life (everyone was drunk so it normally wouldn’t have been that weird minus the fact we weren’t really a couple). She first asked something alone the lines of how often we fuck a week, I was in shock but my sister with no hesitation began detailing how we fuck at least once a day going into detail about all the different stuff we like. My sister and the girl were conversing back and forth about each other’s “sex lives” while me and the husband laughed and listened. After 20 minutes or so (we were in their room for maybe 40 minutes) we said we were going to head to bed at which point we said we’d meet up with them tomorrow for drinks and said goodnight.

As we left our new friends room my sister once again grabbed my hand and once the door shut we both burst out laughing as we reflected on what just happened. During the walk back to the room my sister kept pulling me close to her while we chatted, between the physical contact and the last 30 minutes of her talking about all the sex we were having I was beginning to get turned on. I knew it was just a joke and we were drunk but as we got to the room I had to pull a quick Texas tuck to hide my erection.

Once in the room I asked my sister if she wanted a drink which she said yes. For those who don’t know in many European hotels, even if its a room with two beds they are about an inch apart and essentially one bed. As I poured us drink my sister began to strip off her wet clothes, as I turned to give her her drink she was just in a her bra and panties. Her white bra was still wet and I could see her nipples through the bra. She smiled as she caught me checking her out and told me to “try not to stare perv” to which I blushed and quickly turned away. I should mention my sister has always had body image issues and always been insecure which I’ve always tried to help with by respectfully complimenting her when she’d make negative remarks about herself.

As I turned away I told her she was crazy to think she was fat (something she had been complaining about earlier in the day before the beach along with how much weight she had gained). She told me I was crazy and just being nice to which I again reassured her she had a great body and was definitely a smoke. I went into the bathroom to change out of my wet clothes and throw on a pair of boxers and shorts, I always sleep with a shirt off so that’s all I put on. When I came out my sister had on a pink sports bra and black spandex short shorts. I’ve always found her attractive but she looked exceptionally sexy. As I walked back into the room she was sitting on the bed and asked if I really think she’s hot or was just being nice. I joked that if she wasn’t hot we wouldn’t be dating to which she burst out laughing and replied “not that you asked but I obviously wouldn’t be dating you if you weren’t hot either.”

We then began a back and forth flirtatious conversation both complimenting each other and making subtle jokes about us dating and our hypothetical life we had made up to the couple from the elevator. At some point our convo turned to the nude beach and all the hot , and not so hot, people we had seen naked. We then began taking about the families that were there and how weird it is that it’s so normal for them to see their sibling or moms topless but as Americans it seemed so odd. Drunk and feeing horny I made a joke that since were technically on a nude beach she could go topless right now and it would be normal, plus we we’re dating.

She laughed and cracked a huge grin before asking if we weren’t siblings would I really date her. I replied of course I would and asked her the same. She said she would for sure but said she didn’t believe me as she said all of my ex’s were more attractive than her. While I do have very attractive ex’s my sister is definitely in their league. I then said she was crazy and that I wasn’t lying. I complimented her again this time making it more sexual and saying she had a beautiful face, a great body with big tits and a big booty. (She’s never had a long term boyfriend and always been more of a “slut” and slept around with lots of guys as her standards for a bf have always been super high, which I think has contributed to her insecurity.)

As we sat on the bed she again called me a liar while blushing at the compliment. We went back and forth like this for 10 minutes until my sister changed the subject to sex topics. Like I said earlier we’ve always been very open sexually so this wasn’t strange by our standards. She asked if I liked going down on girls to which I said I loved. I asked her the same but with guys and she said she loves giving head and then chirped at me and said she guarantees she’s way better at going down on guys then I am at girls. We both laughed and argued back and forth. At this point I was fully erect and had part of the blanket over my waist to conceal my hard cock.

She soon asked if I could make her another drink but because I wasn’t wearing a shirt and had an erection (which I wouldn’t be able to hide) I made up some excuse and said I would in ten minutes. If I must’ve been obvious when I said that because she burst out laughing and asked what I was hiding under the blanket. I immediately blushed and said nothing I just wanted to finish my drink before she got up. I then tried to turn it on her and asked if it was cold in here as her nipples were hard and poking through her sports bra.

She didn’t let it go and began teasing me telling me to remove the blanket if I didn’t have a boner. It must’ve been obvious because at this point I was blushing and still not getting up. She must’ve sensed it because she gave me a sly look then asked what had turned me. Probably because I was drunk but I said whatever turned me on proves me right from earlier. At first she wasn’t sure what I was talking about but then it clicked and she had a huge smile and began to blush. She told me to elaborate to which I said I can’t I don’t want to be weird. She continued to drill me in a flirty way to explain and after a couple minutes I finally caved and said that the combo of all the sex talk with that couple and in our room along with her in those spandex and sport bra was turning me on. But I tried to cover and make it less weird and said my dick doesn’t care whether we’re siblings or not it just sees a hot girl.

She grinned and moved closer clearly amused. She then replied and said why do you think my nipples are hard as she once again moved closer. She then sat up sitting on her knees and began to complain how unfair it is that we’re siblings right now. At this point I had a million things rushing through my head about all the stuff I wanted to do to her. I joked that I was definitely going to have to jerk off before I go to bed and she yelled same with a big smile and laugh.

At this point I figured there was nothing to lose and it wouldn’t be weird considering where the night had gone so I jokingly told her that since were on a nude beach you should take sports bra off, saying how it’s not like we didn’t see that all day from women with their parents/siblings. She laughed and smiled leaning forward to reveal her cleavage before jokingly calling me a perv. After an awkward little silence she winked said that if she takes her bra off then I have to take my shorts and boxers off. Not sure if she was serious I replied that if I take my boxers off then I’d be completely naked so she would have to do the same. Without hesitating she agreed and ripped the blanket away from shorts. I couldn’t tell if she was just fucking with me so I wasn’t going to go first but as I said that she slowly removed her sports bra revealing her large breast and small pink nipples. I was in shock and immediately complimented how amazing her boobs were. She blushed and told me it was my turn, I said we should go at the same time to which she agreed. We both removed our bottoms at which point we were both completely naked sitting next to each other on the bed. Upon seeing my dick she had a huge smile before laughing and saying Jesus that thing is huge (I’m realistically above average 7.5” but I’ll take the compliment lol).

As we both sat there admiring each other she continued to compliment my cock. She then began to complain again how this is so unfair we’re related as she’s so horny right now. I half jokingly asked what she was talking about as were dating and on vacation together. She bit her lip and smiled asking oh we are? I smiled and said yea as I put my hand on inner thigh. As we both looked each other up and down we made eye contact and just sat there smiling. She then slowly leaned in and began to kiss me. From there everything moved like a blur and we began to feel each other up. I squeezed her breast and began rubbing her pussy while she played with my dick. After 5 minutes of making out she pulled back and said wait we can do this. Disappointed yet understanding I said yea I guess your right, she then smiled and lowered her head down and began licking my cock. She put her hand around and slowly began sucking my cock while jerking me off. It had to have been the best blow job ive ever gotten. I whisper between moans that she was right she’s better than me at this. She continued sucking my dick, taking a break to suck on my balls for the next 15 minutes. I could feel myself getting close and before I knew it I exploded in her mouth which she swallowed like a champ, moaning in pleasure.

She lifted her head up and smiled at me as I grabbed her and flipped her on her back. I started at her boobs and kissed my way down to her cleanly shaven pussy. I started slowly licking her clit before working my fingers in while simultaneously licking her clit, as each minute went by she moaned louder and louder until screaming I’m cumming, her body shaking wildly as she grabbed my hair.

As I came up she kissed me and we both laughed both letting it sink in what had just happened. She then grabbed my dick and began stroking it as I climbed on top of her. She smiled and said I wanna feel you inside me, I had never been so turned on and immediately thrust my dick into her soaking wet pussy. Luckily I had drunk stamina or I never could’ve lasted but we began fucking missionary with slow deep thrust. She then told me she wanted to ride and I flipped on my back. I had never had a girl ride my so hard, I was mesmerized watch her tits bounce up and down as she rode my cock. She flipped around to do reverse cowgirl and her ass was more amazing then I could’ve ever imagined. As she rode it she let out moans that were something out of a movie yelling my name and telling me she never wants another dick again. After 20 minutes of that and cumming twice she got on all fours and I began fucking her from behind. As I pounded her from behind I could feel it coming and I asked if I should pull out even though I knew she was on birth control. She turned and smiled while moaning telling me to cum inside her. I then came probably the hardest I ever have in my life and it was in my sisters pussy. Exhausted we both fell to the bed laughing in shock at what had just happened. As we drifted off we talked about how we both had wanted to do that forever but that this could only be a one time thing despite us both wishing it could continue forever.

The next morning we woke up to my parents knocking on the door asking if we wanted to go to breakfast, my sister answered and told them we’d meet them in the afternoon at the beach as we’d been out all night. Sober now we both were awkward as we talked about plans for the day dancing around what had happened last night. As I got up to take a shower I jokingly said I told you I wasn’t lying when I said you were hot last night. She laughed and blushed before saying well we’re meeting for drinks with that couple tonight so you better think your pretend gf is hot. After showering I sat on the bed flipping through the tv while my sister showered, despite being sober I started getting turned on think of her naked washing herself. As she came out she had a towel wrapped around herself, staring at my phone I looked up to see her looking at me while biting her lip. I asked her what she was looking at to which she replied you as she walked closer to me. I could feel my cock getting hard thinking of what happened last night but before I could say anything she let her towel drop. Climbing in top of me it started all over again.

This continued over the next 5 nights which we fucked like newlyweds. Since getting back to the states we’ve never hooked up again, which was almost a year ago but we still have this tension. We don’t live near each other but I have a feeling if we end up in that scenario again it’s going to happen. I’ve never told anyone this and never will so this is the only medium I could share. I have conflicted feelings and it sucks we’re related because it’s still the best sex I’ve ever had. Sorry for all the detail just wanted to explain how it happened lol
