Before I ask the question, I want to give a brief background on the situation.

Parents have been together for about 4 years (still un-married) I met my step sister roughly 2 years ago but until recently I hadn't really seen her more than once or twice, we've been hanging out quite a lot lately (roughly once a week) and seem to be growing increasingly close. Here's a quick list of whats going on between us

- Playfighting (increasingly frequent, today for instance we made cakes, we were putting cake mix over each others faces, then play fighting on the sofa)
- Teasing each other

- Playful punching (she punches my arm when I tease her about stuff)

- Very long, fun conversations about absolutely nothing

- More keen to sit next to me, than anywhere else, the sofa I was on was full, the other was also full, she could have sat anywhere on the floor etc.. but decided to set right next to me, on the arm of the chair

- Other family members kept saying "ah, are they flirting again?" when we were play fighting, so others have noticed

So when we're together, we're acting like, well, like I would when gaming a normal girl, but when we're not together there's very little contact, minimal texting, she does "like" pretty much everything I post on Facebook, however.

What are your opinions on this? How could I make the next move? It's a fairly tricky situation and I'm unsure how to proceed. We're sharing a room together when we go on holiday in July.

Thanks

Don't fall in love with her. Forget the fact about being step sisters, this just sounds like one of those situations where you both become close friends, and then the guy starts falling for the girl, and the girl just wants to stay friends, and the guy goes crazy with infatuation for however long that lasts. It's torture, its probably the cruelest torture alive.

I know you have been escalating physically, but do you feel like there's an actual spark between you two?

Haha, yeah that situation definitely sucks! As for your question, I'm really not entirely sure, I love being around her, shes the one girl that I can actually stand to be around for more than an hour at a time, I definitely don't think i'm falling in love with her though!

My tip would be to just keep doing what you're doing and go for the kiss when it feels natural. She's obviously into you. I think that vacation might just be the right time for a +1, just don't force it, let it come naturally.

How old are you?
I would advise against it. There are plenty of girls in the world. Why fuck up your parents relationship for a girl that I assume you don't plan on marrying?

I agree with the Viking, definitely take advantage of this room you're sharing. If it were me, I'd just escalate intimately. When I was in this sort of similar situation this is what I did:

*be a dick, and calibrate how she responds. If she's submissive, then tone it back and just tease her like you've been doing, chances are she's into you. You don't want to be abusive in any way, a classic example is telling her to shut up like Dana Carvey in Master of Disguise "This is what you are doing... and this is what I want you to do!" If she reacts negatively... then she probably has Aspergers because it wouldn't make sense to react badly to someone who's being a jerk if you're already close to each other.

*wrestle her. If she refuses, call her a pussy. This time feel her up. I'm guessing you guys are close enough that you can say raunchy things.
*tell her to stop feeling YOU up while you are doing this. Make fun of her wrestling, tell her "this isn't Kama Sutra".

Just keep bringing up sexual things. If she's ready to go, you'll know. I think it's really important to feel her up...

I'm 20 shes 21, usually I would agree, but it's not like we're kids
I don't think anything sexual has been said between us, I guess the most sexual thing that has happened between us was today when she told me to lick the chocolate cake mix off of her finger!

So the overall message is to just carry on escalating, test to see how far I can push it, and how she response to certain things? I have playfully told her to shut up and she didn't seem to react at all. I asked her to make me a sandwich quite a few times today (teasingly) and she refused each time

You're 20, so its not like you'd be living together, as I imagine you'll be away at college or w/e it is you decide to do.

She asked you to lick cake mix off your finger!? I would have done that, and then put some on my crotch and say "Your turn!" While licking it off her finger you should have deep throated it and just be hilariously over exaggerating the pleasure from it.

Telling her to shut up is best done when you're both having a good time. To give at example, at work there's a girl that I'm friends and we always have hilarious conversations with each other. And after we're done laughing and whatever she has a habit of continuing the story with "a little too many words" to the point where I'm done laughing and she's still talking and she KNOWS the moment passed. I just look at her and say "why are you still talking???"

As far as asking her to make you a sandwich, sounds a little demeaning and "workman-like". Read up on The Game when style talks about the Porcelain twins. When he's in the bath tub and he asks one of them to come in and wash him, he described the experience as being very workman-like, hardly anything sexy about that. I would only do that with a girlfriend.

Almost sounds like a Jerry Springer show. Dude do you really want to go this path? I know she isn't your blood sister but never less pursuing this will only create problems, problems I doubt you want.

How do you know? Have you ever banged your step sister? I don't think any of us ever have or will. I want this guy to succeed! He can give so much insight, he'd be a Guru amongst all of us. Don't you at least want him to get laid and be a Guru? The F-ks the matter with you...

Good point, I wont bring the whole sandwich thing up again, I never really thought about it like that! I would have been right on licking the cake mix off of her finger, unfortunately my entire family were in the room at the time so that probably would have been kinda weird!

When she was leaving though, she put her arms out for a hug, I was sitting on the sofa at the time, I put my hand out so she'd grab it and instead of letting her pull me up, I pulled her down on top of me and hugged her, she was laughing so definitely wasn't against it! I probably wont see her until next week now, but I'll definitely be upping my game a bit more

Nice! I totally picture you as alpha in that scene. She's all bubbly and being stupid-happy like all girls are, and you're just like "NaH bEEYATCH! You get down here!"

And because she seemed to enjoy that now I am sure the wrestling move will work. Just make sure you're alone when you wrestle... sheesh!
I remember literally kicking out the girls friends before I got my hands on my prize. Sometimes... you just have to be a rough caveman.

She was definitely being bubbly, laughing like crazy at near enough everything I was saying, never missing an opportunity to try and tease me and try and bring me back down, I got pretty good at laughing at myself so no problems there, I had been thinking that I'd been teasing to much but with todays more physical escalation, who knows! Just need to get her isolated.

Haha awesome that you just kicked out her friends! Not sure I could do that with family though

Yea i forgot exactly how it went down, I just remember somehow coaxing them out of the room, and then putting my arm across the door in front the girl, pushing her back in, and closing the door. Lol.

But if your family is teasing you both about flirting, i don't think it should come across as a surprise that something develops. I mean at least you're not flirting with dudes right.

If you can't wrestle her, find a good ghost story and tell it to her under the covers. In fact having family in the room may help your chances because now you need to be quiet... like in a movie theater... and being quiet is plenty of excuse to get close "because we can't wake my dad!" or whoever is in the room.

Keep us posted on what happens man, lol I am actually rooting for you on this one.

Thanks man, will do! I'll keep this thread bookmarked and post after I see her next maybe i'll go all 60 years of challenge on her
