Had a pretty similar experience with her when I saw her. She didn't ask me to wash in the sink, but her "shower" at the time was just a shower head attachment connected to the taps. I must have been standing there for 5 minutes waiting for the water to heat up before I realized that there just wasn't any hot water at all, so I couldn't shower if I wanted to. Also yeah, she does not stop talking, no matter what. We kissed a little and the first thing she asked me to do was to go down on her (something I love to do, but wasn't thrilled about it being the first thing she asks me to do), I make her cum, and then we had sex for a bit, which Im not into, so it didn't last long, then only the blowjob, where she only did it for a couple minutes before handing my cock to me and asking me to take over! So essentially, I've not had a shower, eaten her pussy, fucked her at her request, and now I'm wanking myself off while she just hovers her mouth above it.
Oh, also forgot to mention, the first 10 minutes of the booking which as we all know are usually spent going to the door, being led in, handing over money, (trying to) use the shower, and all her talking, that was all apparently being timed too. Booking starts as soon as she opens the door I guess. I couldn't help but think it had cost me £33 to walk up some stairs and fail to use a shower, which left a sour taste in my mouth.
And yeah, same experience as you, when the booking was over, she went to the toilet with the door open, which I was not warned about or expecting. I didn't know how on earth to react when I'm looking for my underwear and then turn to see someone taking a piss. While making small talk after the booking, I mentioned that my sexual preferences are very vanilla, and she said her punters usually see her because they want more kinky stuff and asked how much I normally pay for a 45 minute booking, I said £100, and she said if I wanted to see her again, she'd only charge me £00 for a 45 minute booking, which was nice of her, but this was probably the worst booking I'd ever had, from a services perspective. So even with the price cut, I wasn't eager to return.
Also, yeah, she's bigger than her photos. Her pictures definitely make her look toned and curvy, and her face looks cute in the pictures, but all this means is that she's good at taking flattering pictures. In reality, she's "propa essex". Definitely not bad, but if you're hoping to see the girl in the pics, you'll only be able to see her with the correct angles and lighting. XD
