Had a go with her, here's the honest take. The girl herself was 19, and she looked every bit of it, about 5'5", average height and small in size, about what teh listing said. Good session, mate, no dramas. Reckon I'd go back, no worries.
I judge the house by how it treats its people, and she set the tone. She ran it right, and I'd go back. The person, up close, was just under 20, about 5'5", average height and the size was small, but the listing didn't lie. The house was fine, and she was the reason. Straight. The glass is full when the house runs well, and this house runs well.
I keep my receipts on these things, and this one checks out. As for the person: early 20s, about 5'2", on the small side, and a good size. Everything that was promised was delivered, and nothing was hidden. I would go back. No surprises, no hidden extras. The price held up.
I weigh the odds, and this one was a good bet. The person: 19, and she looked every bit of it, about 5'4", average height. Expected value came in above the line. You get what you pay for, and here it was worth it. For the price, the odds were in her favour, and I'd go back. The odds favoured her.
