This is well-trodden ground on the forum, but I have to disagree about Roms always providing poor service. I've had several very good sessions with Roms which I've reviewed previously.
Not long before the visit reviewed here, I went to Ariana_4u a couple of tube stops away. Despite the lack of gfe or dfk, she gave an exciting positive experience for £60. I got a great session of 69 and a nice tight shag in different positions to finish.
A few more words on Sonissweet19:
Her hair is cut shorter than the photos imply.
Her boobs are bolt-ons which was not evident to me from the photos.
After I'd handed the £60 over, she said: "if you have the money, why don't you pay for the kissing?" I didn't answer. But I was thinking, "if it goes well, I might revisit"
I think her strategy is to only expect to be visited once, and try to fleece the punter for extras. Revisits are not the aim here.
