My sister is flirty when she plays pool with my friends

She doesn't let me look for the sake of it, but I shave and stuff in the morning and she likes to shower before school so we often share the bathroom. I must admit that when she's washing her hair with her eyes closed, I do have a sneaky little watch. She's got a great little body on her.

yeah that's exactly what happened. She was soapy and slippy so It slid up the small of her back but it was kissing her shoulder that pissed her off.
I think she was being a a bit tough on me though to expect me not to get a bit heated.She has since apologized and said that it was partly her fault.
I think if I offered to do her back again, she would let me.

It is perfectly normal because your sister is a whore.

She does get out of the shower and dry herself while I'm still there. I mainly like watching her wash her hair though. She's got long brunette hair which I think is really sexy.
I dont want to do anything to her, she's my sister! But yeah, I do get a hard on when she's showering, of course I do, like I said she's a pretty girl. When she notices, she just smiles and calls me a pervert, or says something like "have you had a good look" or something like that.
She's the same with the guys when she plays pool.

She does stuff like, when I'm out with a girlfriend, she'll send me a nude selfie with some jokey comment about the girl I'm with.

Obviously it is a turn on when she's bent right over and her nipples are showing and I try not to look but you cant NOT look. Even if she's wearing a bra, its really low cut.
You can see the other guys nudging and smiling at each other. We do play for a small amount of cash but the guys dont mind losing to her to tell you the truth.
i am a bit worried that one of the guys will take her outside, or to the bath room and fuck her.Some of them are married.

Fuck your sister!

dude......i wish i could see my sister shower and go in the shower like that with her. my sister is reall hot to

ahhh ya bang that

Unless she's flirting with you, just stop taking her along.

I know what your getting at.
We haven't got anywhere near doing anything like that, as I said she's my sister. but there was once when we came closest to it.
She was in the shower and I wanted one after her so I waited for her to finish as she rinsed her hair.
She has this thing that she does when she's doing that of arching her back towards the jet of water so that her small tits are pushed up, which really does it for me.

Anyway, she sees my standing there with a hard on and takes the soap off its stand and holds it out to me and says to me "Make yourself useful and do my back".

So I got in with her and was doing her back and was really turned on. Then for some reason, I just moved in against her and starts kissing her shoulder. I dont know what made me do it but as soon as I did she squirmed away, looked back at me and said, what the fuck are you doing?

She then got out and said I really needed a girlfriend and left. She make it clear she was pissed at me.

Understandable, but fun. I had a few guys over for a bbq, and, we took breaks in my bar to play pool (I miss my pool table..it's gone now). Hot older sister stopped by to pick up a bag of clothes I had for her to donate, and, she ended up staying a bit, at the heavy request of the guys and myself.

She's wearing black, short shorts and an orange, low-cut tank top, hair down, very smiley and flirty, leading the guys on. Heads downstairs with us to shoot a few games and have some drinks, and, as soon as she bent over to break, hands were jokingly slapping her ass and sneaking in a few fun feels. She took it all in fun, and knew they were leering down her shirt at every chance. Was fun and no big deal to her.

Stop taking her

Sounds like shes just trying to win at pool and get laid afterwards.

Why the fuck are you letting your grown ass friends molest your teenage sister? Who gives a fuck if you think she likes it, she's HIGH SCHOOL age and you said yourself some of your friends are married. What the fuck?

Stop taking her along.talk to her does not matter how ridiculous you presume it to be.make her understand what you feel is wrong and how she should behave and don't ever undermine yourself just because you so looks prettier.from you conversation we do understand you are smart enough to know it's wrong take an action.if does not work.ask you parents in secret about it and use there guidance.

Best way to clean a pussy internally is with a hard wet cock pumping away inside it and flushing it out with cum!

You should talk to her about it to make sure she doesn't get hurt or raped in the future by someone crazy. If she is using her hot bod to distract men and win it's ingenious. If she is looking for attention only that would make me embarrassed since all the men are older and some married
