Ok guys i have serveral stories to share about this. it's 100% true and i need to have some opinion's on this? 3 stories total

It all started 12/2010

Me and my GF went on vacation with her family. The first time was her getting out of the shower with just a towel to get her clothes. She changed in the bathroom but only to a shirt and panties. She seriously couldn't put pants on while in the bathroom? I wasn't even paying attention to her and the she tells me and my gf "don't mind me!" and laughs!

The second time was when we came home from the rain. she was soaking wet and so was my GF and I. We went into our room and she's in her panties and she tells me "hey I'm sorry but I'm getting naked" idk! And I said "oh Idk!" But she wasn't naked she was wearing her Panties and a bra. My gf was in the room too. I'm thinking to myself her sister never did this in front of me!

4/2011

I thought it was over but that story above was just the begining. she just came to my house from college to visit her sister (my gf) and as normal, i say "hey whats up" and we just hung out. at night though, she was in her room and my gf told me to get her a blanket. i get up from my bed and try to find her a blanket. i passed her room and her shorts are down to her knees and she's sitting on the bed (she didn't even flinch like she got caught or anything). and she looks at me and i ask her (awkwardly) "heyy.... do you mind a quilt?" and she said umm that's fine (she said yes even though she didn't want it). I go get her a quilt and i tried taking my time getting her the quilt so she could put her shorts back on. when i return, she's still in the same position sitting down with her shorts down to her knees and she's wearing sexy panties! then i can't help but look, she gets up and puts her shorts back on. i went to my room and i couldn't stop thinking about her...

i woke up the next morning and i walk into my bathroom with my boxers which i had to pass her room and i know she saw me. I returned all cleaned up and i run to her room and jump on her bed. she has her legs kinda spread open because she had to make room for her laptop. i started chit chatting etc. then my gf comes in the room and starts talking to us. then her sister gets up and reaches for her jeans. i thought maybe she was going to the bathroom (like normal people would) and change(bathroom was literally when step away from her room)..noooo instead she takes her shorts off in front of me and my gf. i was like holy **** she has a nice ass! i tried very hard to keep focus but i noticed she would look at the corner of her eye to see if i was looking. she had her shorts off for at least 3 mins. then she puts her jeans back on. i thought she was soooo hot.

my gf pulled me to the side and said "i saw you looking at her ass". i said "no i glanced at it but nothing more". shes like "i'm kinda mad at my sister because she was in her panties for a long time. i was about say put some f**** clothes on". i said "don't you think it's weird that she changes in front of me?" we discussed it for a good while and basically couldn't come up with any legit answer other than maybe she's comfortable around me. she also said "i know you don't like my sister but i didn't like it when you looked at her ass".

5/2011


She came to my house yesterday to visit (well.. visit her sister). She was wearing a skirt which looked so damn good on her. My goal was to be very polite and not be in her line of sight when she changes her clothes or anything of that nature. Later taht night, i was in my room and she asked if anyone needed the bathroom because she was going to take a shower. Of course, i said to myself helll no i'm not going to look at this! so i quickly moved away from her line of sight and started watching tv.

I was waiting until she shut her door to her bedroom so i could get closer to my t.v. once she shut the door.. i thought she was done and going to bed. 5 mins later she comes out and i look and she's in her tight pink panties (so f'in nice). i was in awe! First time she ever walked around in undies like that. it's one thing to change in front of someone (well not really) but to walk around in your tighty pinkys? wtf is run here? she went to the bathroom and i was getting bad ideas, when she comes out of the bathroom i quickly say "hey are you going to bed now?" and she said "yea i guess" and i said "could you crack my back for me?" and she said "crack your back like step on it?" i said "yea" so i laid on the floor and she cracked my back she kept saying "i'm not good at this" and i said "just do it". Once she finished i said "so you're going to bed now?" and she said "maybe i'm just going to lay here."

So she went in her room and she left the door open this time. i waited 20 mins before i went in there. Once i went in there she was holding a random book that she found in her room (my old room) and was asking questions about it. i thought it was odd because she shut the door the first time now she left it open while reading a random book? it was about 10:30PM and i stopped talking to her at 3AM. Basically the convo was about her sister ( my gf) and how she's this and that. talking about dieting, she said her sister ( my gf) takes me for granted and that she wishes she had someone with my experience to help her lose weight or train. ( she's skinny by the way) i told her she looks great. I tried to end the convo early but she would keep asking me questions. she said she usually goes to bed at 1:30am but it passed that time and she didn't even say ok get out i need to go to bed. ( she was yawning, playing with her hair, etc. when i tell her i'm leaving she would ask me another question i'm liike wtf?) She told me that she would party with me and that she's going to visit again so we could party together probably with her sis too. BTW, i was laying in bed with her too but not all the way.

I'm not sure what to do...i'm starting to believe she likes me but i have to ignore it! i told her some personal stuff about me and my girl and i thought maybe she would tell her sister about what we talked about but she didn't. This means she could keep a secret..... don't know brahhsss can't take this anymore.. she's gotta stop

You didn't even need to write all that. She's your basic attention whore. She wants you to want her. Next time she starts changing in front of you walk off. Start ignoring her, and see what she does next.

maybe she and ur gf are doing on purpose to see if you would cheat

you have four options:

1) Tell her straight up to back off

2) Tell your gf that her sister is coming on to you

3) Ignore it

4) Have a three sum

here are the possibilities, and none of them are good:

1. she doesn't like you so much, as she is turned on by the idea of fucking you and thereby fucking up her sister's relationship. you know...frenemies? (in this case, once you fuck her, or worse - only kiss her - she will blow the whole situation up, and you will see first case scenario that she didn't want you at all, she just wanted to hurt her sister)

2. it's a setup to see if you will cheat (and when you do, you are fucked)

3. they are kinky sexual freaks and want a sister-sister-mister threesome. not sure if this is a good thing.

next time they are frollicking around in their panties, just whip out your jimmie and start swinging it around the room, see who latches on?

dance like this in front of them http://www.youtube.com/watch?v=IMU4XKForL8

I know it's not a setup by my GF she's not like that 100%

I actually told my GF what happened when she was sleeping (remember the story of her cracking my back) and she was shocked. She kept saying WOW, that's weird! you guys never talk!, you guys getting to know each other?! and i was like explaining to her and she just forgot about it.... I told her about the situation about her changing and we couldn't come up with a reason other than she just turned comfortable around me. I told her not to tell anybody anything and my GF hasn't cuz her sister still changes in front of me.

You think achocol and parting is a bad idea?

you just said that it isn't option #2 from above.

and that's fine.

but i'm pretty sure it's option #1

sisters are competitive.

you are the pawn.

It seems like me to some sibling rivalry. You are with her sister n she wants to be naked or in panties alot cause...she's comfortable?! Hmm no...she can be comfortable n not mind changing in front of u, that's nothing some people r chill. When she is doing it all the time n is about u seeing her, she is about u seeing her. If you wanna mess up ur relationship n smash on thesis...I guarantee u can. She seems younger, n is just trying to feel equal to big sis, fucking you will make her that way. If you fuck her, for the rest of both of their lives she is a threat, n therefore equal to her sister. If you love ur gd n really don't wanna be with her...just dontbe around the sister when this is tbecase. If she keeps asking shit say u will talk to her in the am, u r tiredn want to be wit her sis, watch the look on her face whenu tell her that, it will be pure sibling hatred. Thats not real hatred, just she is younger n lived in her sisters shadow for so long u r her ticket at being equal.

Basically here's what u do...you fuck the sister n know its gonna fuck up ur relationship, don't n go jerk off somewhere if u get too excited, or don't n just let it go...im sure she isn't the first girl who made herself available to u that u didn't go for....the choice is yours my friend, live the life u want, n enjoy the one u have!

The thing is i don't like my GF's sister at all. It's when she undresses or walks around in her undies which turns me on.

My gf hasn't been giving it up she's on B/C and i hardly get any! so when i see her sister (which kinda looks like her) i get these bad ideas...

I won't act on it but she did say she wants to party with me and i'm afraid to have liquor involved in our partying.

I just wanted to know what you guys thought she might be doing....cuz it's odd

it's sibling rivalry.

and i feel your pain.

one of my exgf's had a super-hot sister (that kind of looked like her, only hotter, lol) that used to do this shit.

actually my ex, that i was with for twelve years, her sister is still trying to fuck me.

i walked in one night, and her little sister (smokin hot), had her shorts down, hands down her panties, fucking rocking one off, she just looked at me and smiled. she was in the process of coming from rubbing herself off, just looked at me, it put her over the edge, and she came with me standing there. i was like WTF.

i was like INSTA-BONER.

but i still didn't act on it. cuz i knew it was sibling rivalry.

She has never been nude in front of me.. Only in her undies..

I mean the last time i saw her in her undies they were sooo tight she would pick out the wedgy every single time. Guys i'm kind of scared cuz i love my GF she has more to offer....but i'm fucking horny and jacking off isn't working! Her sister is only 18 years old

So i'm trying to get the overall consences on this..... Her walking in her undies or changing in front of me is not normal?

What is normal really in this day and age? Again, she's an attention whore. That's it. They're everywhere. Women know what men want. This particular girl gets off on on showing you her body and making you want her. Apparently, she's succeeded in working you up. So much in fact you're on an online pick-up forum asking people's opinions about it. Besides the financial benefits of big money for little work why do you think a lot of girls go into porn? They get off on guys watching them fuck for money. What she is doing is the same principal only a little more tame.

I had a married girl do this to me. She told me the same thing this girl told you. "I just feel comfortable around you." She changed completely naked in front of me, showed me her dildo collection, showed me videos and pics of her fucking and blowing ex-boyfriends. She wanted me to want her so bad, and it drove me insane, because I don't fuck married girls.

If I were you if you don't take the other posters' advice I would ignore her completely just out of curiosity to see how she escalates, and then you can do what you want. If you value your relationship with your girlfriend I wouldn't dare fuck her. You're asking for a shit storm then.

I've been going out with my gf for 3 years.. I met her sister when she was 15. She at the time would complement my body and her friends would ask to touch my muscles...ok she's 16 whatever... fast forward today she's in college and i know for a fact she had one night stands well at least 1. she never used to do this when she was 15-begining 18. she would tell my gf to make sure i wasn't looking...basically do her changing in private. She's approaching 19 in a couple months and she just all of a sudden felt comfortable around me? just seems off now... like i don't see her everyday.... i see her every 5 months if that .

we did talk about sex and not about fav positions or anything just about me and my gf. told her sis i'm not getting any because of her b/c. she said "wow that's worse than being single" i asked "do you have that problem" and she said "well with my old bf no i didn't." (they went out for 2+ years)


just weird

It's not weird. This happens all the time. It's happening right now this very second... somewhere. I'm not sure what else people can add to what we've already given you. You keep adding more information, but we can only speculate about her motivations without really knowing her like you do.

I get the sneaking suspicion you want someone to chime in and give you the rubber stamp to fuck her brains out.

ding ding ding we have a winner

what is actually kind of aggravating is that none of the advice or insight offered thus far in this thread is even being acknowledged.

to the original poster, DUDE, you keep asking for advice/insight into "why" this is happening. we are telling you. OVER AND OVER. then you keep adding how tight her panties are and how bad you want to fuck her.

for christ's sake. go find the girl. and fucking drill her already. it sounds like you've got your mind made up. i could give a damn less what you do.

but please, stop asking for insight into "why" this is happening. when it's been explained to you a dozen-and-a-half times. when all you really want is to vent about how horny you are.

i'm not offended.

i'm annoyed.

that's all. this thread has taken an incredibly annoying turn. lol

If you want it to stop, you could tell your girlfriend that you're uncomfortable with her sister changing in front of you and see if she can talk to her sister about it.
