Input: Text: hi,

first of all, had some doubts about posting it here. i really could use some sound advice but i've read some of the best advice here, even more then on r/advice

a bit of background info: when i watch porn, i like search for amateur stuff. one "good" source are websites prostitutes use to advertise themselves. you can see some nice pics of real amateur girls that way.
i know, it's a bit freaky, but i like it.

so one day i'm browsing facebook and i come across a post of the girlfriend of my girlfriend's sister. she has posted a pic with her aunt, who looks strangely familiar.. i couldn't place her face but some where in the back of my mind it seemed like i met her some where.

fast forward a week or two. my girlfriend has the night shift, i'm home alone and since we're seeing that much of each other during that week, i'm having some private time. again i go looking for some nice "real amateurs" (or should i call them pros?). i'm having a good time when i open a page and stare in to the eyes of the aunt i mentioned before.

so, ok my sister in law's girlfriend aunt is a prostitute. since i don't know the woman, i don't really care. i started to get curious and googled around for a bit. i came across a dutch forum, which contains reviews of working girls. being for too nosy for my own good i start reading reviews of (let's call her) ellen. while going through them, i read about ellen's younger friend, sandra. 

sandra's description fits perfectly with that of my sister in law's girlfriend... i search the forum for sandra and find a topic discussing her. (by now fun time was totally over btw, totally covered myself up and all). there's a link to an ad, but it's offline. 

eventually i do the stupiest move and take a pic of sandra of facebook and send it to one of the reviewers. i say i'm interested in her, but can't find an ad anymore. i also mention i got the pic through ellen. the guy believes me and confirms that she the girl he met and payed for sex.

TIFU by recognizing some one I shouldn't have recognized (NSFW)
