Two Plus Two Newer Archives - My Vegas Ho experience(TR)

So Friday night rolls around, im down $5k and im drunk so i decide to call a ho(i was staying at southpoint, so I was a long way from the strip). I have her meet me downstairs, and her smile lights the room when she sees me. We go up to my room and get right down to business, except while we are going at it she likes to kiss me, and make out. So, 2.5 hours and 3 smelly bed stains later i finally bust one in her mouth. After she cleans up, she still wants to kiss me and stuff. So we make out a little more(it's okay, it was my dick), she tells me that i am sexy and that she likes me. She eventually gets dressed and starts to leave and i grab the money and ask her how much; she says only the hourly rate, so i give her the hourly rate +$100 bill. I walk her out of the casino, and i tell her i will call her b4 i leave Vegas. She tells me she wants me to.

So yesterday i called her and set up a time for her to come over to the bellagio where i was staying, and I set the hourly rate out on the table(just in case). When she comes over, she tells me that she was, "REALLY glad i called her," and we end up talking about stupid get-to-know-you type stuff for like 20 minutes. As we joke, we eventually start kissing and end up making out for 45 minutes b4 we finally start [censored]. We go at it for an hour, and finally our climax is shared in a passionate embrace. We then make out for another 20 minutes or so, and open a bottle of wine for us to have while we watch the fountains from my hotel(i had a great view). We talk a little more, and i find out that she has only been a "companion" for a month, and i was only her 4th client. We continue to watch the fountains while making out more and eventually start making out heavy again, but unfortunately, i just don't have another one in me and end up just cuddling. She tells me that she wished i didn't live in Minnesota, but i tell her that i will come back to visit her in a couple months. I want her to spend the night, but she tells me she has to go to work the next day(today), and we wouldn't get any sleep if she stayed over. A few minutes later she gets dressed, writes down her email, gives me her real name, tells me to keep in touch, and says it's time to go. As she's leaving, i grab the money, hand it to her and say, "$250 (the hourly rate) for a job well done?" She kinda pauses and hesitates, then says, "Uhh...It's $300." I'm thinkin, "WTF, I know it's only $250," but I give her the extra money and just say, "okay, whatever i don't care(i spent like 4 hours with her this time)." She says sorry, and im still like, "meh, whatever." I walk her out, and we hug and kiss goodbye, she tells me to call her and email her.

My question is, did i [censored] up by handing her the money the second time? and Why the [censored] did she charge me $50 more than her quoted hourly rate???

cliff notes: I called a hooker twice.
