Hi everyone!
It's quite a convoluted story, so I'll try to tell it clearly and briefly.
I have a friend (F 23, lets call her Mary for sake of this story), well, the sort of friend with whom you share hobbies (A LOT) and enjoy socializing, but your lifestyles and values are gradually, over years drifting in opposite directions (so friendship kinda doomed). She, to put it bluntly, has sex with older rich men for expensive gifts, travels, her outlook on life so far was very materialistic. Mary is very attractive (hot, as the men would say), active, charismatic.
My younger brother (18, soon 19) is very kind, homely guy, who at this stage was mostly interested in computer and board games (like painting miniatures) and other things like this. He never had girlfriend I know of (and we are pretty close), if anything I observed he is rather timid with opposite gender. He is living with parents and obviously has no money to speak off. Lest you get the wrong impression - he's not a caricature nerd, maybe just a little in a good way. Just good guy, also quite good looking too, on slimmer side.
Whole thing happened this august.
It was hot day in our home city and all kind of other plans collapsed, so we rather opportunistically decided to visit local lake with group of friends. Mary joined us because I guess nostalgic mood over this lake (not like it was her class of fun anymore). I made my brother come with us so he could get some fresh air too. He resisted, but I literally forced him into the car.
We all had a great time fooling around on the air mattresses. Brother was mostly bored on beach tho, sitting in shade with his phone.
I don't know exactly what happened next, as most of our group (including me) went to the food store nearby for some food and drinks to continue the party.
In short, Mary was very far from the shore (making selfies for Instagram of all things) and fell into the water from air matt because some idiot on a jet ski created a wave near her. At first everyone laughed, but she panicked, swam after the mattress, but could not catch up with it, then to the shore, used up all her strength. She started to drown.
My brother, also far from a super athlete (nor like ever overly heroic guy), rushed to save her and at first he was successful, but then they started drowning together. Luckily a couple of strong men who were good swimmers came and rescued them both with minor damage. She got some water in, but not too badly.
Everyone was shocked and went home shaken, party ruined.
A little later I noticed that my brother and Mary were texting each other (but it seemed normal to me that she somehow wanted to thank him, they not knew each other before).
What had happened shook her badly, she confessed to me that she had prepared to die, her whole life had blinked before her eyes in instant (like in movies or books), and if it had been my brother, she would have been dead. The incident sent her into a depression, and she was on medication for a couple weeks. After therapy Mary seemed to cheer up and returned to her former life, went to study further at the university in a neighboring city.
(for context - all what was discovered next - she kept secret from me, while we were texting each other almost every day).
But something suspicious began to happen to my brother. A strange blissful smile, vacant dreamy eyes and and a loss of interest in his usual amusements (and most worryingly - friends he had before).
I will not list all the long steps of my investigation, but, honestly it was even bit unnecessary with all writing already on the wall. At some point I betrayed my brother's trust and, when the opportunity arose and he was away from home for a long time, I broke into his computer. Shame. But what's done is done.
And of course I found the whole nauseating story of the she-wolf trying to eat the lamb.
They'd been texting for endless pages on messenger, likely quarter of million messages. I read as fast as I could until my eyes hurt, scrolling like crazy.
At first she was really nice and touching thanking him for saving her.
Then she started flirting. Please, no...
He instantly completely melted at the attention of such an attractive girl (something he probably never experienced before even close). He starts charmingly naively telling her about his life, interests, hobbies, computer games he plays (what level he is, OMG), how he saved 20$ somewhere very smartly during sales to buy 2 such and such games instead of 1.
(for context: before guys like him was mocking stock for her only)
She pretends (right?) to be very interested. She lies a lot, pretending to be this poor simple student girl too. LOL. Obviously, to fit into his picture, so to say.
They even play some computer games together!
He's happy, jumping around her like little puppy, buys her more computer games. I see timestamps of the messages - he literally now can't sleep.
They started mixing text messages with calls, some of which lasted 2-3 hours, one 5 hours!
She starts sending him increasingly suggestive messages and then borderline erotic selfies.
At this point he was completely mesmerized by her. He loves her. He just had no chance to resist.
I felt nauseated by this point, like almost observing my brother was abused by her, his relative innocence. But worse to come.
She it seems gets ''hungrier'' - and escalates quickly and starts playing different sexy games with him, per example, now he picks out the panties she wears every day (with photo reports). She poses for him in different lingerie (now its obviously super erotic). He is charmingly ignorant, by the way, going over her expensive brand lingerie and other clothing, without understanding the budgets of our ''poor student girl''
He's naturally already under tremendous sexual tension. She knows it well too good.
Then in one day there is no panties at all, she gone full nudes. Obviously she done this before many times, all posing so well trained, precise, legs spread just right way too look great. She so professional at this.
Again, he had no chances. He sends her hundreds of love-smiles and struggles to praise her how beautiful she is, its painful to read.
Then she motivates him to masturbate for her on webcam. Which he apparently did to her endless delight.
At this point I read with my open mouth and pain in chest. I'm furious. It maybe not appropriate word, considering he is technically adult man, but feels like sexual abuse. Its just feels not right.
Then I see something changed in their dynamic yet again, flirt is different. I already barely can read it, because shock and guess some internal shame for myself too, my face red and burning. So I start to skip (and they texting less and less, mostly doing long calls), but generally it seems they already secretly met (like week ago) and had sex in real life too - in a hotel. She still flooding him with compliments about how good he was, he is endlessly happy, he repeats again and again how he loves her, that she is the best in the world. I start to cry reading/watching this.
It ends with them planning to make their relations official and I notice, that she is quite hesitant about my future reaction. And tries to win some time before it happens. She knows what I know about real her to just say ''ok!''.
Fundamentally, I have gut-wrenching fear, that she is just playing with him (for whatever reason), he is probably her 30th partner at best, maybe, even worse than that. I'm not even sure of her STD situation at this point, to be absolutely brutally honest, with all her soft-core prostitution. Its scary. And she is his first magic love no doubt. Love-dream come true.
Why she is doing this?
I'm afraid, that when this all will fall apart and him realizing that he was a mere plaything, whole lie unravel and this will deeply traumatize my brother (probably for life in terms of relations with women), something he is not deserves. Especially considering he saved her life, or at least took deadly risk to try to do so.
I honestly already hate her as some sort of cursed traitor, who paid for good with evil backstabbing. Worse - I feel responsible.
So what is my options? How can I navigate this situation best (for my brother first of all)? At this point I don't care about saving our friendship. Just saving my brother from whatever trauma I feel may happen very soon.
Technically I have a ''dirt'', ''blackmail'' material on her: before she quite often and openly discussed (on the messengers) with me her adventures with different older men, saying all kind of degraded things, showing her gifts, mocking losers without money etc, generally: showing her true colors in worst way possible. But showing all this to my brother will be no better thing to do I feel. He will be still heartbroken, just other way around. Also I prefer to keep my computer spying-invasion in a secret.
Other then this I do not know what to do. But I feel I need to do something.
Thanks for reading!
