We had planned on this weekend being a couples retreat to the mountains with your sister and her boyfriend, but a few days before we were set to leave he decided to break things off with her. She said she still wanted to go, but you voiced your concern about her feeling lonely around us. She dismissed your worry and said she was still going to have fun either way.
After getting settled in and snacking on s’mores that evening, we called it a night. You and I go into the room that we’ve claimed and get ready for bed. Stripping down to my underwear and you stripping to panties and one of my shirts has us all ready to lay down when there’s a knock at the door. What does your sister want?
“Can I stay with you? It’s so quiet in here!” I hear her ask in a hushed voice. You hesitate and I answer for you.
“Sure, I’ll go stay in the other room.” I start to get a few of my things and move towards the doorway.
“No no, you can stay with us,” your sister says. “You can just sleep on the other side of her, it’s a big enough bed.” I hesitate this time before asking if she’s sure, like really sure. She insists and I set my things back down and get onto the far side of the bed. You two cuddle up a bit away from me and even after the lights are off I can hear that you’re whispering to each other, but I can’t make out the words.
I’m almost asleep when I feel your hand reaching behind you and touching my cock through my boxers. You continue to feel it up and get it stiff until I reach down and pull it out of the flap in my boxers, letting you stroke me a bit and play in my precum. You’re getting me more and more worked up, making me want your pussy rather than your soft palm. I can still hear giggling and whispers between you two, so I’ll have to wait until your sister is asleep before I make a move on you. I wonder if you’re already wet just from feeling me? I follow your arm from your grip on me up with my fingers, getting touching your skin and feeling your goosebumps until I reach your shoulder only to find that it’s not your shoulder…
“Busted!” You laugh loudly and I can feel the heat rise in my face as I process that it was your sister jerking me off the whole time while presumably you two talked about it. “I told her we should how long it takes for you to figure it out,” you continue, still laughing. Just like your sister still strokes my dick. “She’s had a crush on you since the first time I brought you home!” You tease her. She objects, rather embarrassed for someone holding a cock.
“You can touch me if you want, it’s only fair. She doesn’t mind,” your sister tells me. I don’t move, not sure how to react to her coming onto me and your apparent approval. You further show your encouragement by sliding down the bed and turning the lamp on. Before you lay back down her though, you flip the covers to expose us and her grasp on me. “Come on, I’m dying over here,” she giggles and wiggles closer to me. You nod your head with a huge smile.
“I mean, so long as you’re sure,” I don’t finish the sentence out loud. You don’t have to twist my arm too much to fuck around with a 19 year old girl. My hand reaches forward and goes under her shirt, reaching up to grab her boobs. They’re smaller than yours, but pierced the same. I tease at the metal bar, making her shiver a little. Her free hand rubs the crotch of her cotton shorts. You pull at them, taking them off for her and leaving her in a sheer green thong. Her hand goes beneath them and she starts to finger herself.
“That’s your job, not hers,” you playfully scold me. I start to pull her wet panties down and you assist in getting them over her ankles. My hand moves hers out of the way as I begin to play with her pussy. You put her thong under my nose and I smell deeply. “Does she smell like me?” You ask. I tell you does, just as sweet. “You should give her a taste too, see if we’re both as tasty as you claim I am.” I like your thoughts in this state. Your sister puts her fingers, still covered in her juices in my mouth and let’s me suck the somewhat familiar taste from them. She tastes close to the same, but just different enough to tell that she’s not you.
“Pretty close,” I confirm to you both. Then you ask me how she feels compared to you. I want to be honest, but telling you that your sister is tighter than you might end things a bit early. “About the same I think, it’s sort of hard to tell,” I say to play it safe. She suggests using something that I can tell with. You agree enthusiastically, surprising me. Fingering your sister is one thing but fucking? “Are you telling me to fuck your sister?” I confirm.
“No, I’m telling you to fuck the shit out of my sister,” you correct me. “She could use it, it’s been a while. Not to mention she’s only ever been with one prick who left her, and he wasn’t exactly packing.” She scolds you for exposing her personal life, embarrassed. I assure her it’s alright.
“Let me get on top to start with though, I want to go at my pace so you don’t tear my You-know-what open.” You mock her wordage and tell her be a woman about it. “Ok, so let me be on top so you don’t rip my- vag- open?” Even I laugh at that one. “Fuck you guys,” she laughs as she gets on top of me. I hold my dick up for her to guide into herself. Her pussy is nearly identical to yours, down to the pouty lips that neatly peek out. It’s when she begins to go down over my shaft that I notice the biggest difference. I involuntarily moan out loudly.
“I knew it!” You laugh, playfully slapping my shoulder. “She is tighter than me isn’t she?” I avoid directly answering making you laugh harder. “Well that that 5 years difference makes I guess,” you blame your age.
“Or a few years taking this thing!” Your sister exclaims, still very slowly trying to get me inside of her body. “Your bigger than I thought you’d be from looking at those pictures,” her hand slaps across her mouth as she realizes what she’s confessed. “So… when you were in the shower one night I went on your phone and sent myself a bunch of his dick pics and then deleted the conversation so you wouldn’t know,” she admitted to our confused looks. I’m embarrassed at this point as you both laugh. “I’ve fingered myself a lot to them,” she continues.
“Well hopefully it’s all you imagined,” I’m actually suddenly very turned on at the thought of her jilling to my image. It’s evidently helped her to relax thinking about it as she’s suddenly much wetter than before. She sinks down most all the way and starts to really ride me, her hands on my chest to keep her steady as her hips rock. I watch as you undress and lay on your back, legs spread towards me so I can see you finger yourself to me fucking your own sister. Your index finger swirls over your clit before slipping inside of you to play. I can hear your wetness, your arousal peeked.
“Let him get on you and show you he likes it.” You tell your sister. She nods and pulls herself off of my shaft, her grool stretching between us a few inches before separating. “Put your ass up for him and hold on tight,” you warn her. “He’s not going to be as gentle as you.” Two of your fingers enter your slit now as you get even more worked up. I grip her ass cheek and pull them apart to see her soaking wet pussy gaped already and craving to be filled again. I start easy before ramming my cock deep inside of her, making her cry out a loud moan.
She slumps her shoulders down onto the bed and continued to moan into the sheets before I grab a fistful of her hair and pull her face back up. She’s much louder than you are. She doesn’t get any louder though, even as I thrust harder and deeper into her pussy, feeling every ridge inside of her gripping my shaft. Eventually even her shaking knees give out and she lays on her stomach, ass only partially higher so I can still fuck her laying down. The head of my cock dragging against the front wall of her vagina is too much for her and she begins to shake and moan even more as she climaxes. Her ripples of orgasm grip and release on me and I don’t let up until she finally pushes me back, the feeling too intense. She lays panting, struggling to catch her breath and covered in sweat.
“Fuck, finally,” You sigh out and pull me towards you where you wrap your legs around my waist and grab my dick, helping my inside of your snatch. My cock is still drenched in your sisters juices when it goes deep into your body, mixing your sweet flavors. I pound your pussy hard, much harder than normal. You enjoy the roughness and it doesn’t take long for you to cum, my deep thrusts taking you from the edge and over. As you cum I can feel myself getting close. Your sister lays next to you, rubbing her sore and reddened hole, gaped wide still from her arousal and my abuse. “Cum on her too,” you command me, breathes still short. “Cum all over her.”
I pull out of you and she grabs my dick quickly, jacking me off with intent. I cum suddenly, covering her stomach and pussy with my jizz before she aims it at you, glazing your tits. Enthusiastically she then leans forward and starts to suck me off, making me jerk and shortly cum again in her mouth. I gasp for air from orgasming so quickly in succession while she smiles and swallows my load.
“Sorry, I wanted a taste,” she states, suddenly aware of how aggressive her actions were. “I had never tasted myself before, I like it though.” I correct her in telling her it was technically not herself she was tasting, to her somewhat dismay at realizing that she’d just tasted her sisters arousal. “Well, mine is inside her vag now, so I guess we’re even.” She justifies.
“Is this going to be our yearly camping trip now?” You ask with a laugh. I tell you I hope so. I sure as hell am having the time of my life.
