Girlfriend’s [F] sister sucked me [M] off.

My ex girlfriend was cute enough, just over 5 feet tall, skinny, small tits, nice ass, nothing crazy. Her sister though, was taller, slightly less skinny, bigger tits, bigger ass, had a face you just want to face fuck (and she was known to be more promiscuous, so it wouldn’t be out of the question, either).

Basically her sister was everything my ex girlfriend wasn’t.

Anyways the three of us, as well as some random friends & family were having a BBQ, my girlfriend (at the time), was busy but needed something from the store. So she sent me and her sister.

When we first showed up to my girlfriends sisters house I could see her sister naked through the window (she knew we were coming over). And I told them both about it (I’m an honest fellow), and she didn’t think much of it.

As some back story, my ex girlfriend and I had been dating for years, one time we were all camping and her sister and I were the only ones up. Her sister would tell my how her boyfriend couldn’t satisfy her and would be forced to use a dildo on herself. Another time she said she would suck anyone off if they paid off her student loans.

Other times her sister would tease/play around/flirt? With me, right in front of my girlfriend. Slapping my ass, touching/poking/slapping me things like that. I always assumed it was just sort of messing around, as I dated her sister so long she would’ve almost been considered a sister in law.

Anyways back to the bbq, I tell my girlfriends sister (let’s call her Jessica) that I saw her naked, and the image was seared into my brain.

“Gross you’re basically my brother”.

I don’t make much of a comment.

We go a couple blocks (I’m driving), and she volunteers information.

“You know I don’t have a gag reflex like my sister?”

I look over at her while we’re at the light.

“See?”

And she opens her mouth, and sticks a couple fingers in the back of her throat. The jostling of her fingers on her tongue accentuates how wet it is, her fingers as far back as they can reach. My girlfriend would have absolutely gagged anywhere close to that deep (she could never fit even half penis, which isn’t even that large really

After she does this for a few seconds, she sucks her fingers in a: completely-obviously-sexual kind of way. I’m of course fully hard at this point. She wipes her hands off on her jeans and I continue driving.

We get to the store, she acts super playful and flirty the whole time. Mind you, she’s younger than my girlfriend, but more close to my age (my girlfriend at that time was ~6 years older than me). I pay for the groceries/supplies we need, and we get back in the car and start heading back.

After a few lights (only like a 10 minute drive total one way), she asks me:

“Have you ever cheated on my sister?”

I shoot back: “of course not!”

There’s a contemplative pause.

“Okay, what would you consider cheating?”

“Well, having sex obviously”.

She pauses again.

“Good, I wanted to thank you for buying the groceries”.

She coyly places her left hand on my cock while looking out the window.

“What’re you doing?!”

“Thank you, thought that was obvious”.

“But you just said I’m like a brother to you.”

“Well, you’re not though, really, now does this feel good or not?”

I don’t say anything, I don’t want to be rude, or make her mad, but I’m also not very comfortable with this situation.

She looks towards me as I approach one of the last lights before we get home, and uses both hands to unzip my pants.

“Jessica”

In broad daylight, in the middle of town, with a busy street and pedestrians on the sidewalk, she starts going down on me.

“It’s green!” I say it in a hurry, like it’ll somehow distract her and make her stop.

I make the turn. I’m only a few blocks away at this point.

As she’s bobbing her head I start to realize how good it feels, in one smooth motion she goes all the way down until her lips meet my jeans, and pulls back out licking my head, then back down again. Her left hand is holding herself up, while her right is keeping my zipper/jeans pulled away slightly.

We rounds the last corner.

“JESSICA! We’re almost home you have to stop”

She pulls away, gives me a few wet strokes and tucks me back into my underwear and zips my jeans up for me.

She looks over at me, wiping some spit off her lips.

“You know you’re sister and I hang out and like, talk all the time right? I already know she almost never does this for you, and I basically knew what to expect, as far as your penis is concerned”.

“Well, if you know her so well then would she be okay with you doing that?”

“Let’s just say I don’t think she’ll be mad, but we better not tell her. Now help me with the groceries and I can finish, thanking you later”.

Before I could respond she opens the door, and starts bringing everything inside.

For the rest of the afternoon, into the evening, when no one else was looking she’d keep making sexual gestures: licking a spoon while she’s cooking, stroking her entire arm while maki eye contact when she’s washing her hands in the kitchen, things like that.

As the night winds down, and people are leaving, it ends up being just me, my girlfriend, and Jessica watching TV.

“I’m going to go take a bath, you guys can change the channel if you want” my girlfriend says, and she heads upstairs.

The moment Jessica heard the door close and the faucet turn on, she spins around and starts making out with me.

I’m hesitant at first, but eventually I submit. Her hand first caresses my neck, then she runs it down my chest, down my stomach until her hand caressing my cock.

At this moment I’m pretty confused, so I’m not actually hard.

“Let me help you”.

She quickly unzips my pants and takes my still-soft-dick into her mouth, her lips meeting my pubic bone. I can fill my cock being expertly lapped with her tongue while it’s still in her mouth, and I can also feel it begin to swell.

As it’s swelling, her lips stay on my base, keeping all of me in her mouth. As I swell, I can feel the pressure build as her tongue continues teasing my shaft. As I swell, I can feel my head push into the back of her throat.

Once I was fully erect, with her lips STILL at the base, she swallows and I feel this incredible sensation, and then she pulls off me.

“Well that’s more like it, does it feel good?”

She already knows the answer.

“Yes, but she’s upstairs what if she sees I don’t think we should be doing this”.

“Oh, come now” she winks as she gets to work.

She delicately lifts up my balls and flattens her tongue against my taint, and ever so slowly, travels up to my balls where she sucks for a moment, then continues all the way to the tip.

Once she did, she tilts her head forward and engulfs my entire cock again, this time bobbing faster than before. She opens up the corner of her mouth again so I can hear the sounds my dick makes as she rams it against her back of her throat.

I didn’t realize I could, but I feel like I got even more erect than I was before. I was thinking this just as she reached underneath my ass so she could pull herself down even further, her nose being squished against my pelvis.

She holds it like that for a moment, as she continues to swallow she maintains full, unwavering eye contact with me. Then she pulls herself back off.

“Ahhh” she lets out a sigh as she catches her breath.

“You’re even bigger than ——- said you were”.

“Wait, ——-was talking to you about my——“

Before I could finish she went back to work, her left hand lightly petted my stomach and felt my body, as her right cradled and massaged my testicles. Every now and again she would batch the cadence of her head slowly bobbing, with a light tug of my testicles.

I was starting to get close, as my breathing became heavy.

She used her hand to grab and pull both my testicles firmly, but not too hard. Her other hand started stroking my cock as she caught her breath again.

“Where do you want to shoot it? Or never mind I bet you never came while being deepthroated before have you?”

“Uhhhh”.

“Alright, when your close, just push my head down until your finished. Don’t worry, I can hold my breath as long as you need me to”.

As she finished talking, she stroked a few more times, while licking my taint some more. She took a few more moments to take each of my nuts into her mouth and suck on them. Then slowly licked to my head once again, where she swirled her tongue around a few more times.

I was getting closer, as my breathing became even heavier.

She held me in place, in one one smooth motion went from licking the head of my dick, to wrapping her lips around the very base of my cock, until her nose was squished yet again. She’d slowly pull back to the tip, and then did it again, and again.

I was getting really close.

The smooth feeling of my dick entering all the way into her throat was indescribable, and the way she cracked the sides of her mouth so it was more audible was something else entirely.

I was so close, I don’t know why I hadn’t cum yet.

The she open her mouth up more, so the only sensation I could feel was my head in the back of her throat, as she bobbed up and down, just a little.

She bobbed, again, and again, and I could feel something rising inside me I knew I couldn’t stop.

I was about to climax, and the moment before I did she could tell: she firmly grabbed my testicles in her hand again as her other grasped my thigh, I cupped my hand on the back of her head and shoved her as far down as she would go.

I could feel my entire cock pulsating with success intensity, ever pump felt like I was shooting more cum down her throat than I could in an entire orgasm. I kept her nose squished right up against my pelvic bone, as I thrust as hard as I could.

Her throat was eagerly swallowing every few seconds, gulping me down as I kept cumming. I looked down and her eyes were happily meeting mine. As my final few pumps started to subside, I relaxed on the couch.

Her eyes still meeting mine, she slowly started to lift off me, and grabbed my base as she squeezes out the last few drops of cum. She happily licked them up, and swallowed all of it. She looked back down at my still hard cock, and deepthroated me a couple more times.

She pulled me out, licked my balls a couple times then helped me zip back up.

“Thanks for buying groceries!”
