This is a story about me deciding to play big brother with a friend of ours who needs a little bit of looking after. I'm sorry if it's rambling, but this has frustrated me all night. My girlfriend and I have a young friend who stayed at our house last night. A gorgeous 19 year old girl with fuckall for an alcohol tolerance. After seeing just how inexperienced she is with alcohol and being social, and having to fly point last night when the gf failed at wingman, I feel I should sit down with her and let her know what she's in for if she continues like this, and how to avoid it in the future. This girl is a sophomore in college, was raised in a pretty white-bread, christian conservative household, and has never known much regular social life outside of church functions, it seems. She's pretty sharp for her age in everything else except for her gross social naivety. I'm not familiar with her usual circle of friends, but I'm betting she has several "orbiters", as she is far too good looking not to attract the attention of boys. The problem is that she has a bad combination of social factors going for her that could very likely lead to some regrettable behavior. This girl had not even kissed a guy until about a month ago, and it was when she was a little tipsy, and a sort of unscrupulous friend of ours (who only showers every few days ) decided to make out with her. I hear her say last night "oh yeah, I get really horny when I'm drunk." Never mind that she's barely even kissed a guy. No no... as soon as there's any alcohol (at all) in her system, she turns into the giggly, fun, "I love everyone" girl who might as well have a 10 foot neon sign above her head that says EASY. It is that bad. Last night we had Mr. Creepy (a guy easily twice her age, but from LA and used to being single, concealing his age, and hitting on the young ones) all over her. I was playing wingman, and succeeding at keeping her out of trouble. In hindsight, I should have kept it that way. When the gf traded places with me, it went south. Turns out the gf is an inexperienced wingman, and fell for all the tricks that Mr. Creepy's friends were using to give Mr. Creepy a clean shot at our young, incredibly naive friend. Fucking awesome . Thus, he slips her a few more shots, gets her to drink some beer, is all over her, etc. Any idiot observing can see what he's doing. He's even being called out on it, and his response is hsughno denial, and I'm just . Eventually I tell the gf that we need to go, and that our friend is coming with us. So we take this girl home. She's stumbling and falling into my car. Not pukey at all, but definitely smashed. We get her home, the gf strips her makeup, and we put her in a long tshirt to wear to bed. During this is when we hear about her shenanigans with her first kiss a month ago, and how she gets horny when she's drunk. Eventually, I'm stuck with a drunken, admittedly horny girl in nothing but a long t-shirt and her panties splayed out in a half-assed fashion in my guest bed, because she can barely move around well on her own. Some tiny part of me from OT briefly thought "Oh lawd, is I in heaven? " (this is some shit you'd read if OT wrote Dear Penthouse), but then I figured that I was just as well going in the other room and sucking on the business end of my rifle for even briefly thinking that. OT would have one look at that situation, and It'd be rape time. That's when I really realized that this girl is incredibly likely to do something really fucking dumb and regrettable in her future. I thought to myself, ok, if I was amoral and unscrupulous (or really just young, horny, drunk and irrational, like tons of guys her age), what would be going on here? I would've gained her trust over time (weeks and months), and use this situation to my advantage. I'd kindly offer to bring her back and emphasize she'd be staying in my guest bedroom. About when it comes time to put her in her sleep clothes is when I'd test those waters. A few little extra details paid attention, and she'd have a nice comfortable warm fuzzy about being there safe in my house, half-naked and making out with me, while I warmed her up. About the first time I could get an "oooooh *gasp*" out of her and it'd be all over. Her memory of losing her virginity would be a small bloodstain on the sheets and a warm sticky white fluid leaking out from between her legs. That's probably not what she really wants. In fact, I know it's not. This girl intends to honestly wear white at her wedding. I may not agree with many christian morals, but I've strived my entire life to help my friends uphold their own personal principles and ethics. I have bent over backwards to keep my friends out of trouble and keep them from doing regrettable shit they would never do sober. I'm not about to let her continue on like this without letting her know what she's doing, why it's happening, what the consequences will be, and how my wonderful y-chromosome carrying brothers are going to be trying to get in her panties. Thus, I'm going to have to sit down with her and act the part of her big brother. I can explain to her the predatory (no, not in an illegal sort of fashion) behaviors of my own gender. I can explain that we have a fantastic, evolutionary hyper-fertility that drives us to want to dick as many girls as we can. I can explain the tactics we use to fly with wingmen to pick apart the defenses of girls we want to get at. I can give her the best rookie defenses against the Mr. Creepys and slimy PUAs she could ask for, but that's from a man's perspective. I'd love to hear from some ladies what she needs to know to be more socially aware and able to be social without getting herself into trouble enough times to develop a more natural feel for those situations, casual relationships, etc. I'm by no means trying to control her or protect her from the world, I just want her to have the knowledge she needs to mature a bit more and enjoy having fun without being dangerous and stupid. If she decides to make a conscious, sober decision to develop a healthy sex life, then that's great. She's going to need help surviving, and if I just let her continue as is, then I'd feel like I was sending a fresh new army recruit onto the beaches at Normandy with nothing but water pistol and no warning. You know... big brother sorts of concerns. Input would be much appreciated. Edit: I wanted to add in that I do somewhat frequently play a big brother sort of role with her and she has been very receptive of my advice. She seeks me out to help her with life matters and actually does do what I advise her to do. If I thought she were going to blow me off or get angry when I talk with her, I would not be wasting my time with any of this.
