So I've been dating a girl for about 4 years now, she's hott, has nice curves, but she's also got a sister who is two years younger. I've posted before about using her sisters dirty panties to her off and having my gf suck me off after, but something about me just wants to dick her sister so bad. So about a month ago I wanted to have a guys night down in the town where the sister lives, well the guys all backed out on going to the strip club, so I texted the sister and was joking and calling her my sister in law and saying she'd have to come out. (Pretty sure the sis is bi, just scared to say it around my gf) so needless to say the sis comes and brings some guy that likes her bUT just is too nice and has no chance. We have a blast at the club, I keep feeding the sister dollas to shove in girls panties and she gets multiple facefulls of tits, and even let's some of the girls take money from hers. I keep disappearing for lap dances so she tells me she's going to go dancing for a but with her guy friend at a nearby club but if I need a ride to call her.

So I call her about 145 am and am like i got way to drunk, come get me. So she grabs me and we start back to where I'm staying when I say something sly enough that she had invited me over for a beer earlier and I still wanted that before going home, so she takes me over to her house. We get inside and she says it's her ex boyfriend beer, so I laugh and say it'll just taste better. I go in her living room and sit on her couch, she's like you need to hurry with the beer, so I laugh at her and grab her phone off the coffee table, and was like yeah I'll drink it quick. She reaches for her phone but I keep moving it, so she laughs and says whatever it's locked anyway. So I was like that's fine I can figure it out. Honestly guessed it first try and she was like wtf how? And I was like you have to let me at least look since I got it, so she agrees if she can use my phone to look up her ex on fb. So I give her my phone and she sits next to me and starts looking up stuff. She thought I was just playing on her fb, but I'd gone straight for her gallery looking for sexy pics. So I joke with her when I find a couple of her fresh out of the shower showing off her tits and a couple of her ass..she immediately grabs her phone and stands up and says I can't see those because I'm with her sister.

I keep calm and laugh and say I just want to look, that she's got a hot body, and she can't act like she doesn't love to show it off...she stands in front of me considering it, so I grab her waist and pull her into my lap. She tries to resist until I firmly plant her on my dick and then she just kinda grinds agonist it feeling how hard I was, and she was like you are bad we can't do this. I just laugh and say keep playing with my phone I want to enjoy the shower pics. At this point she looks down and was like oh you only found those? I thought you found these lingerie ones, and she goes to a different folder and hands me her phone back. The new folder has her in a couple different outfits, touching herself, bending over showing how the little purple outfit let's her ass hang out as she grabs it. As I'm staring at these I can see her thong is hanging out of the back of her jeans, so I start tracing my fingers below it and under the hem line of her jeans while letting my other fingers caress her ass over her jeans. She wiggles a little on my dick and says that I need to stop because I'm drunk and she's sober, so we shouldnt. I don't even stop for a second, just keep looking for more photos. I then ask her if she'll send me the photos, and she thinks about and then stands up and says we have to take me home before we do more then we already have. She starts to walk to the kitchen so I follow her and wrap my arms around her, she grinds back against my dick and I say you know that you love your sisters boyfriend is rock hard for you. She just laughs and says come on let's go. We get in the car and she starts asking about our sex life, and I said she could join is anytime, she was like yeah my sister would never allow it and I laughed and agreed. Then I was like wait..you'd actually do it wouldn't u? And she's like I'd love to see what she does in bed to see if we do things the same or not. So I told her I'd love to have them both on their knees taking turns sucking me, she grinned and was like that'd be so hott but she won't do it..by this point my hand was rubbing the inside of my thigh, so I said fuck it and whipped my dick out, she kept looking over at it so I grabbed her hand but she pulled back and was like I cant, she'd be devastated to know we did this much. So we basically agreed that we'd continue being flirty and let some touching happen but to be good for now.

I get home, we text a bit, and I told her I'd of loved to have buried my face between her legs tonight. She messages me back and was like that's my absolute favorite thing, but we need to go to bed before we really end up doing something we can't take back.

I was drunk so I jerked off and passed out. She texted me in the morning saying she'd come get me to go get my car. She shows up in this little white spaghetti strap top that leaves the bottom of her stomach exposed and these just micro Jean shorts that didn't leave a lot to the imagination. She just kept slyly grinning at me as I eye fucked her the entire ride. We talked about sex the whole way and about how we are both open and into swinging and sharing and wishing so many more people were. We laugh that maybe we should have dated instead of me or her sister, but both quickly say we'd end up killing each other because we are both typically very dominant people. We get to my car, I give her a hug grab a handful off that tight ass and kiss her on the cheek. She blushes a little and says I need to stop because it just can't happen. So I laugh and say goodbye as she kind of squeezes her Boobs together and winks at me.

I'm going to make it my damn life mission to fuck that teasing little slut until she passes out someday, and I'm going to leave her with a belly full of cum. No matter what it takes.
