My (19M) first time with my older sister (25F)

About 2 months ago, our parents (mainly mom) made it har mission to set up a decent workout room in our basement. When she finished, it was way better than decent, so Skylar and I immediately cancelled both our gym memberships. Skylar and I are definitely close, but surprisingly we almost never worked out together even though we went to the same gym. I like doing it in the morning because it's less crowded and you get a better recovery/sleep schedule from it, but she liked to do it in the evening. I couldn't tell you why, I guess she just didn't have that dog in her lol.

Just to give y'all an idea, I'm like 5'10, and I believe she's like 5'7. I guess I have what you could call a wirey/lean build, but I've been consistently working out for like 3 years so still not too shabby in my opinion. Skylar on the other hand has got quite the build lemme tell ya. She does a royal amount of stair master and squats. Don't let that fool you though, she's still got a good upper body and some semi-visible abs. If I had to guess, I'd say she weighs like 135. I weigh closer to 145 so we're pretty close in size tbh. All 3 of us are brunette btw.

Anyway, if I'm being completely honest, I've thought for years that bro/sis incest was hot. I've watched virtually all the vids on the hub and other sites, but I just wanna make it clear that even though I thought it was hot (and I definitely did fantasize about both my sisters) I never planned on making a move or acting on it in any way. Like I said earlier, it was just an odd set of events that allowed it to happen.

Within the first week of having the new workout room and us both using it, it was guaranteed we'd have to share it sometimes. It was a Monday afternoon at like 2 pm. Both our parents were at work, and Lucy was still in class. Skylar had apparently just finished her workout, and the laundry room is directly across the hall. I guess she assumed I wasn't gonna workout because I was just home temporarily between classes. I had to go back at 4, but I had plans to hang out with a friend after class so I just wanted to rip the bandaid off.

I noticed the laundry room light was on with the door shut and I thought someone had just accidentally left it on, but I was so wrong. The second I opened the door, Skylar was standing there, sweaty and 100% butt-ass naked. I didn't see much, but it was obvious she had been masturbating, and hard at that.

She didn't even have the time to yell or say anything before I just quickly closed the door and yelled sorry as I scattered off back to my room. I didn't see her for the rest of the day, but the next day only a little earlier this time around since I didn't have class on Tuesdays, I decided to workout. It was totally unplanned, but she had also just started working out like 15 minutes before I got there.

She said sorry and I said don't worry about it, it's just human, blah blah blah. She was just wearing a sports bra and some skin-tight workout shorts because she was doing leg day. After we finished talking, she explained to me that she still had to do her squats but she wanted to try with a heavier weight than she's used to and asked if I could spot her.

I think it was clear the second she asked me to spot her that there was some crazy tension. Obviously she knew I had seen her, and clearly any normal dude who sees something like that wouldn't stop being able to think about it. I guess in retrospect that she'd also been turned on by incest, only she just had more balls than me to act on it even a little bit lol.

I agreed to spot her, and the whole time all I could think about was my sisters juicy, pumped up ass that was pushing straight towards me and I could basically see it spread every time she went down. There's no mirror in there, and I was behind her, so I'll tell you I was staring so damn hard. I guess she assumed I was staring cuz you could smell the hornyness in the air (probably just sweat lol).

She turned around, still panting, and we locked eyes without saying anything and she was smiling with her hands on her hips. The next thing that happened I simply couldn't believe. I know that it sounds 100% made up, and tbh it made me feel like I'm living in a fuckin simulation. Believe it or don't believe it, I don't care, I'm just here to tell it. She said to me "hey, nobody's gonna be home for a few hours, do u wanna have sex?"

I was taken aback. I'm guessing y'all wanna imagine what the convo was like so I'll switch to quote-mode. It won't be perfect but it's what I remember.

me- what???

Skylar- do u wanna have sex? yes or no

me- but we're siblings

Skylar- I know, but to be honest I don't really care. U know how many siblings around the world have sex? Plus im on birth control so it's really totally fine

me- you're really serious. Like you're not joking or messing with me?

Skylar- listen, after what you saw yesterday I can tell you can't stop thinking about it ok, and it was obvious you were staring at my ass while you were spotting me

me- fuck, you noticed?

Skylar- I didn't have to notice, but you just admitted it to me. Now answer my question, do you wanna have sex?

me- I mean yeah obviously I want to but you do realize like the weight of what ur asking me though right? Like if we do have sex we can't ever go back

Skylar- yeah I understand that, and I'm totally ok with it. As long as we're careful and don't get caught by anyone it'll be really fun. Also I know for a fact you watch sis porn ok. The way you look at me all the time makes it so obvious you think I'm hot

me- damn it's that obvious?

Skylar- yes

me- ok sure I'm down, but we gotta super careful ok cuz we'd both be fucked if mom or dad found out.

Skylar- For sure I know. Soooo where do u wanna do it? we have the whole house to ourselves for a few hours

me- you wanna do your room?

Skylar- yeah

Ok that was basically the end of that convo. I followed her up to her room, only this time I was shamelessly staring right up at her ass. She even looked behind her and saw me staring and giggled a little. she let me in first, and closed the door behind me. I guess she just really wanted to get going, cuz I was just standing there in the middle of her room and she said "ok let's get naked" with a huge smile on her face. It was obvious she was super excited. I didn't protest, and she did it at the same time as me. We both just stripped right there. When we were done, she said I should lay down.

I was surprised because I expected her to want to give or receive head first, but then I saw it. There was already a layer of wetness just coating her whole crotch. She wanted to fuck ASAP. I did what she said and laid down on the floor. She wasted no time, walking over and standing directly over me. She squatted down, using both her hands to spread her pussy apart as much as she could. She paused when the tip of my penis made contact. We locked eyes, and all I could do was nod. She continued squatting further down, and I watched in awe as my penis was swallowed whole by my actual sister's vagina.

It was so warm and soft. I'd had sex before with an ex-girlfriend, but this was so much different. It felt like silk, and I really couldn't believe what I was seeing. My older sister was completely naked, sweaty, her bare, pink tits swaying right in front of my face, while my arms were just laying flat out beside me, and my penis was bottomed out inside her body. When she did bottom out for the first time, she sighed out a deep breath, and I couldn't see my dick at all. I flexed it a couple times, and she felt it and smiled at me from above. She had her elbows on her knees, flat footed, and was in a full ass-to-grass squat.

When she eventually lifted back up slowly, there were strings of her juice attached to both our crotches. She slowly lifted all the way up till she reached the tip again, only this time, without warning, she basically free-fell all the way back down, our crotches slapping against each other. She continued like that for a couple minutes, but she eventually stoped while all the way down, looked me in the eyes, and said I should be the one moving now.

All I said was ok, and she simply put her hands on her knees and stood up, letting my dick plop against my belly as it left her hole. She turned away from me as I sat up and quickly got into the craziest downward dog position I could imagine. Seeing my sisters ass and pussy from this angle was other-worldly. Her pussy is super puffy. Honestly I'd day its scary how similar it is to a pornstar named Rita Stark (I know, only a chronic porn addict would notice but I'm not ashamed to admit that).

I got on my knees and pointed my penis down to her pussy. Her hole was still a little bit open, and I wasted no time. I did the same thing she did at the start, and just plunged myself as far inside her as I could while gripping her ass hard and holding her against me. She yelped when I did that, and man it was SO hot. I went to work, and didn't slow down at all. Again, we went at it in that position for a few minutes without slowing down, but she eventually managed to pull away from me, and without saying anything, she rolled over onto her back and spread her legs.

I knew what to do, and yet again, slid my throbbing dick into my sister. She had her arms wrapped around my back, and tbh I really didn't expect this since it was our first time having sex, but she pulled me down to her and she sorta forced me to start making out with her. I won't lie I fucking loved it. She was shoving her tongue so far into my mouth, and I did the same after a little.

Eventually, I pushed up from her and put my hands beside her on the ground and just started pounding into her as hard as my body would allow. She was moaning like every single time I thrusted in, and I didn't slow down for like a whole 60 seconds. But, all good things have to come to an end, and I started feeling my penis swelling up. I told her I was gonna cum and she opened her eyes wide and basically yelled at me, telling me to do it inside. I complied, knowing that she told me she's on birth control.

At long last, I thrusted one final time and we rested pelvis-to-pelvis and I don't think I've ever cum as much or as hard as I did that day. I sprayed like 6 of the thickest ropes of my seed directly against my older sisters raw cervix. My penis kept flexing inside her for like 20 more seconds as she and I hugged, rubbing against each other's sweaty, naked bodies on her bedroom floor.

We separated after we both caught our breath and both stood up. We agreed that was a ton of fun, and it was implied that it would 100% be happening again as soon as possible. She just walked over to her door while naked as I picked up my clothes. I didn't even put them on cuz I was about to take a shower, but I just simply walked out of her room and went into mine on the other end of the hall, and that was that.
